Rhvac Version 9 Recent Update History

Version Changes

4/5/2017 9.01.236

  1. Technical changes related to the room notes feature.

3/30/2017 9.01.234

  1. Made some adjustments to the About box to accommodate a wider variety of screen font size settings.

2/24//2017 9.01.232 (Test Version)

  1. Fixed a bug where if you had basement walls in rooms in a system and had the building volume option for the project set to Above Grade the volume value shown on the System Summary Loads report was actually the total volume, not just above grade.

  2. Technical changes related to Drawing Board.

1/16/2017 9.01.220

  1. Fixed a bug on the Miscellaneous report when using metric units, where the entered infiltration air changes per hour amounts shown on that report were not correct.

  2. Changed the default option for new systems you create so that the blower door test type option is set to single-point instead of multi-point.

  3. Added a Help button to the bottom of the infiltration dialog. Added text to the infiltration help topic to explain why identical values entered for winter and summer blower door data results in different steady-state infiltration values.

  4. Added blower door information to the Miscellaneous report that shows up when blower door is your selected infiltration method.

  5. Added a message box that opens when you click "Help | Check for Update" and Rhvac is unable to launch the Elite Software Update Manager program. The message explains that you can instead open Update Manager from the Windows Start menu.

1/13/2017 9.01.215 (Test Version)

  1. Corrected a problem in the Check Figures part of the reports where if you entered a custom building volume the note explaining that the volume is based on custom building volume did not include the asterisks as a prefix to the note.

  2. On the General tab of the Select Reports dialog added an option called, "Show calculated total volume also if building volume option is custom or above grade". This option makes it so if the Building Volume Option is set to either Custom or Above Grade then an additional line will be added whereever volume is shown that gives you the actual, total volume in addition to the other volume.

1/9/2017 9.01.213

  1. Fixed a bug that could happen on the Manual S Performance Data report where if the psychrometrics were unable to solve for the entering coil condition the line showing elevation and supply airflow would be shown three times.

  2. Fixed another bug that developed in the 9.01.205 update, where if you had assigned a system number to a room but have not yet created the system that goes with that system number then an error 9, subscript out of range, would occur.

1/5/2017 9.01.211

  1. Fixed bugs that developed in the 9.01.205 update. One was an error 91 that would show up in the Evaluation of Project window if you had any systems without rooms in them. Another was that on the Winter Infiltration dialog if you had chosen the Manual J infiltration method and the Sync checkbox was checked when you clicked OK the summer value shown on the System Data window would be the same as the winter (and vice-versa). Another was that if you had chosen the Manual J method of infiltration the reports would show zero infiltration.

1/4/2017 9.01.205

  1. Removed the limit of 10 recent items on the Floor Material dialog (the list can now go up to 1000 recent floors instead of only showing 10). Did the same for the dialogs for roofs, walls, glass and doors.

  2. Fixed a bug on the Floor Material dialog where if you sorted the bottom list by one of certain columns such as U-Value by clicking on the column header you would get a message box saying, "No material is selected" upon clicking OK or double clicking the bottom list. Did the same for the dialogs for roofs, walls, glass and doors.

  3. Fixed a bug on the Manual S Cooling Performance Data window where if you changed the Units input at the top from English to Metric or vice-versa the values shown in the gray boxes at the top of the window under "System 1 Loads" and "System 1 Design Conditions" would not show the correct values.

  4. Added the "Disable Auto Diversity" property to the "Tabular Manual D Ductsize Defaults" window.

  5. Added "Building Volume Option" and "Building Volume Value" inputs to the Design Conditions tab of the General Project Data window.

  6. Added a "System Is Isolated" input to the System Data window to let you specify that a system should isolated from the rest of the house when doing certain calculations related to space volume and infiltration.

  7. Added a "Test AC/hr" input to the Blower Door Method - Single-Point inputs on the Winter Infiltration dialog. This input lets you enter an air changes per hour value instead of a test flow value. The program will use the current system's volume as well as the building volume to determine a test airflow, which is then plugged into the blower door formulas.

  8. Changed the way blower door infiltration flow is calculated so that the resulting steady state flow of infiltration derived in the blower door calculations is assumed to be for the entire building, and the current system's portion of that building infiltration is assigned to the current system.

8/24/2016 9.01.200

  1. Fixed a problem that developed in the previous update, where if you clicked the button beside the winter Infiltration input on the System Data window and selected the Manual J Air Changes per Hour Method option on the Winter Infiltration dialog, and had the "Sync..." checkbox at bottom of the window selected, after saving the project or closing and then reopening the System Data window the amount shown for the summer Infiltration input would be incorrect. Fixed the same kind of problem for the Summer Infiltration dialog.

8/22/2016 9.01.199

  1. Fixed a problem where if the project filename had the "%" character it was possible for the program to fail to generate report pages.

  2. Made it so the winter Infiltration input on the System Data window is grayed out and read-only, so you have to click the dropdown help button beside the input and enter your infiltration value on the Winter Infiltration dialog. Did the same for summer.

  3. Made it so you can have a CFM of infiltration that is less than 10. Formerly, all CFM values had to be greater than 10 to be recognized as CFM instead of air changes per hour.

3/4/2016 9.01.186

  1. Added and assigned fields to the project file in order for the Elite Software PsyChart program to be able to include supply side and return side duct temperature rises when importing a system from Rhvac using its Import Air Handler Data and Air Handler Model windows.

  2. Changed the name of the Occurrences ("Occ") input on the Room Data window to Room Quantity ("Qty") to avoid users confusing the input to mean "occupants."

  3. Fixed a bug that could happen under very rare circumstances, where if all the parameters were just right it was possible for the duct sizing calculations to not be able to find a close enough solution in trying to find a duct size that met your Design Loss/100 input, and would report a zero size.

2/17/2016 9.01.184

  1. Added a "Show System Name" toggle button to the Load Preview window, that will add the system name after the "System 1" text.

  2. Fixed a bug that developed in a recent version, where if you selected the Manual J AC/hr method and specified any fireplaces on the Winter Infiltration dialog, the fireplace CFM due to infiltration was not being included in the winter infiltration amount.

2/3/2016 9.01.183

  1. Made it so if you have created your ducts with either Manual D Ductsize or Tabular Manual D Ductsize the Load Preview window will not show a duct size at the zone level. Formerly it had been showing a size that was based on the parameters of the "built-in" duct sizing option.

  2. Fixed a bug that developed in a recent version, where the export to EnergyPro did not include wall, roof and other room components in the exported BLD file.

1/18/2016 9.01.181

  1. Fixed a bug that developed in the 9.01.175 update, which made it possible for certain inputs on the Room Data window to change from the original value you entered under certain circumstances.

1/5/2016 9.01.180

  1. Fixed a bug that developed in the previous update, which could make it so no reports would be selected on the Select Reports window under some circumstances.

12/29/2015 9.01.175

  1. Updated the export to EnergyPro 6 to accommodate the latest version of that software.

  2. Made certain changes to accommodate some foreign language double byte character set systems to prevent a problem where some room data were not being saved to or read from the project file.

11/16/2015 9.01.170

  1. Modified the new "TMY3 Weather Data City" input on the export to EnergyGauge USA feature so it will pre-select the city you selected on General Project Data under more circumstances.

11/9/2015 9.01.169 (Test Version)

  1. Made it so the Bold Critical Path function on the Tabular Manual D Ductsize window makes the text blue colored in addition to the font being bold.

  2. In Drawing Board, made it so the Global Material Change feature is able to change walls whose Kneewall property is True to a different roof material.

  3. Added an option to the General tab of the Select Reports dialog called, "Include company street address in page header". Checking the box will make the 3rd line in the left side of the page header of the reports show the company street address followed by the city, state and ZIP.

  4. Changed the icon and position of the Manual S Cooling Performance Data item in the Project menu, and added it to the main toolbar. Also changed the button for it in the System Data window's toolbar.

  5. Fixed a problem in the export to EnergyGauge USA, where the error message that warns about having too many rooms could be displayed even when you have selected the top option to combine materials and rooms into one big room per system, and the number of resulting rooms does not happen to exceed the maximum number of rooms EnergyGauge USA allows.

  6. Made changes to the export of ENB files in the export to EnergyGauge USA feature. Added a "TMY3 Weather Data City" input at the bottom to let you select the TMY3 city to write to the ENB file in order to avoid problems when opening in the EnergyGauge USA program. And made other small changes to the ENB file export.

9/4/2015 9.01.168

  1. Fixed a bug where you could get an error 6, overflow, if on the Duct Load Factors dialog you had zero entered for both the supply and the return duct surface area, and you had checked the Manual Override checkbox for one or more of the load types. Now if you enter zero for both areas the supply and return override amounts will be equally split between supply and return.

  2. For supply systems in Drawing Board, changed the defaults in the Fan Available Static Pressure property so the pressure loss due to a filter is lower than it was. This change only affects new installations.

  3. Fixed a bug where if you had a window and referenced it to a partition wall with an STD (summer temerature difference) of -1 the sensible gain of the window would be negative. Now the window will use the indoor to outdoor summer design temperature difference.

  4. Took measures to prevent a problem where the second part of the Building Rotation Report (the "Whole Building" part) would sometimes unnecessarily be moved to the next page.

  5. Fixed a bug that developed in the previous update, where if you checked the Manual Override box for latent gain on the Duct Load Factors dialog the percent value you entered in the Percent of Total Load box would not get used, and would be replaced with a different value.

  6. Added a dropdown help button to the upper right corner of all the dropdown help windows that include a list, and in the popup menu that appears when you click that new button added menu selections that let you select the maximum number of list items to allow in any such window.

  7. Corrected the text in the dropdown help window for the wall partition summer temperature difference (STD) to explain that the purpose of entering -1 is to make the program use a CLTD for the partition from Manual J's Table 4B in determining the wall's sensible gain.

  8. Added several example temperature options to the dropdown help for the STD and WTD inputs for walls, floors and roofs.

  9. Added a Manual S Overview topic to the F1 help, which gives you information about finding the data you need.

  10. Updated all the sample Drawing Board projects so that the border is no longer a Container object. Did the same with the Drawing Board template drawings.

8/18/2015 9.01.166

  1. On the Load Preview window and report on the "Misc. Supply" row (if present), made it so if the miscellaneous supply latent gain is negative its value is added to the sensible to determine the value shown in the net gain column. Formerly a negative latent gain was not included due to the fact that we don't include a negative latent gain at the system level when determining a system's net gain. But since that exclusion does take place at the system level for the miscellaneous row it is appropriate, even though if the negative miscellaneous latent gain is large enough it will make the values in the net gain column not appear to add up correctly. Also did the same for the "Misc. Return" row.

  2. Changed the way duct gains and losses are added so that they are split up into supply and return loads instead of all being assigned to the supply side. This change can affect supply CFM values in existing projects, as well as reported entering coil conditions.

  3. Made it so latent duct gains are included on the Psychrometric Chart report, causing the process lines for the SD and RD points to be appropriately slanted instead of horizontal.

  4. Fixed a bug where negative miscellaneous gains were not being shown on the Psychrometric Chart report.

  5. On the Psychrometric Chart report made it so the point label positions on the chart can be changed by the user by editing the program's configuration file for the current user. Also made it so the label names can be edited in the same way.

7/30/2015 9.01.165

  1. Fixed a problem on the System Data window, where if you typed something into one of the inputs on either the heating or the cooling grid on the Equipment tab without pressing Enter, and then clicked Next System or Previous System to change the system the very last thing you typed into the grid could be gone.

  2. Removed a couple of outdated topics in the help file about infiltration.

  3. Changed the way wall directions are written to the ENB file in the export to EnergyGauge USA in order to accommodate changes in EnergyGauge version 4.

  4. Removed the word "unconditioned" from the description of type 19 floors, in case you are blowing supply air into the crawl space.

  5. Added a Roof/Ceiling Slope Calculator to the Room and Roof objects in Drawing Board. This dialog opens when you click the button in the dropdown help for the Roof Slope (Intrinsic) and Roof Slope properties of those objects, respectively. It makes it easy to calculate the roof or ceiling slope in a room, from which the program calculates the area of the roof or ceiling.

  6. Changed the name of the Cooling Coil Interpolator window to Manual S Cooling Performance Data, and made several changes regarding that window. Added the ability to enter sensible to total ratios instead of sensible capacities. Added a Direct Capacity Adjustment input to accommodate the adjustments required by some manufacturers. Added Load and Cap./Load% boxes to show the capacity results with respect to the loads of the current system. Added an Auto Track Load input to let you enter custom total and sensible loads instead of those of the current system. Added an "Include this grid on Manual S report" checkbox to let you choose whether to include the interpolation values you entered on the report. Added the ability to change to a different system. Added a Units input to let you change the units for the interpolation data you enter, in case they are different from those of the current project. Added a Manual S Performance Data report that shows the interpolation results from the data you entered, and optionally shows the actual grid of interpolation data you entered from the manufacturer to help verify that you indeed entered manufacturer performance data values for the equipment you selected. Added a Manual S Performance Data item under the Project menu to take you directly to the window.

  7. Added several help topics to the F1 help, including several examples, to show you how to use the Manual S Performance Data window given various formats of manufacturer performance data.

  8. Added the following inputs to the Cooling Data grid on the Equipment tab of the System Data window: "Adjusted Total Capacity (Optional)", "Adjusted Sensible Capacity (Optional)", and "Adjusted Latent Capacity (Optional)". These inputs are filled in for you automatically if you enter data on the Manual S Performance Cooling Performance data window. If you do not enter data on that window and instead enter these values directly they will be shown on the Manual S Performance Data report, the Equipment Data report and the Room Load Summary report.

  9. Added the ability to reset the menu and toolbars of the main window by holding down the Alt key and right clicking on the background of the main window.

4/28/2015 9.01.157

  1. Took measures to prevent loss of data for projects that have the Drawing Board drawing saved in the project file.

  2. Fixed a problem where the Proposal Maker document templates for Rhvac were not being included in the setup.

  3. Fixed a bug on the Copy Document Template window in Proposal Maker, for the documents in projects listed under the Rhvac Projects tab, where the preview of the document would not show up.

3/23/2015 9.01.155

  1. Made it so the "Delete Component (Shift+F5)" item in the Room menu is available for the Default Room Data window.

  2. On the Tabular Manual D Ductsize window, modified the display of equivalent length data in the right-side fittings grid to show which nominal equivalent length was used for fittings that have a range of possible nominal equivalent lengths.

  3. On the Tabular Manual D Ductsize window, fixed a bug in the calculation of the number of downstream takeoffs for fittings in Group 2, where that number was always being determined as zero, which meant that the nominal fitting equivalent length being used was always the one at the bottom of the range.

3/5/2015 9.01.152

  1. Fixed a problem on graphic Manual D Ductsize where if you had created a Supply Trunk that was not plugged in to anything but it had other ducts connected to it, under certain circumstances the program could lock up upon calculating.

3/5/2015 9.01.136

  1. Compiled new version that includes the changes described below in the test versions.

12/16/2014 9.01.135 (Test Version)

  1. Fixed a problem in the previous test version, 9.01.134, where the program performed slowly in several places.

11/25/2014 9.01.134 (Test Version)

  1. Added a line to show velocity pressure on the Pressure Changes Graph.

  2. Took measures to prevent the program from locking up upon opening the Drawing Board window in a project with huge drawing data in which one or more images have been placed on the drawing in a format that is contrary to the instructions given in the series of online videos, here: http://www.elitesoft.com/pub/videos/db/importfiles2/dbimportfilestoc.html

10/9/2014 9.01.131

  1. Edited some of the text on the Winter Infiltration dialog to make it clear that the direct options at the bottom (Direct Entry CFM and Direct Entry AC/Hr) require you to enter flow for the natural, non-pressurized state.

  2. Modified some of the sample projects that are in Drawing Board mode to have landscape orientation on the drawing.

  3. Fixed a bug on the Room Load Summary report that would happen when you had entered a value for the radiator Btuh per length and had also entered duct load factor values that caused there to be ductwork sensible loss. In that case the Htg Rad Len column values showing the calculated radiator length required would be lower than they should be at the zone, system and building levels.

5/15/2014 9.01.129

  1. Expanded the dropdown help for the Group input on the Custom Wall dialog to show thermal mass descriptions, examples, and descriptions of the examples.

  2. Added the list of Manual J assumed attic temperatures to the dropdown help for the Attic Ceiling Type input on the Duct Load Factors dialog.

  3. Fixed a bug on the Edit Custom Fitting dialog, where if you were editing an existing fitting the program would not save your edits and would show you an error message box that says, "Fitting Not Added," which would show an error saying, "Fitting record was not found."

  4. Changed the captions of the Lighting & Equipment, People, and Profile frames on the Room Data window to include shortcut keys. Now, to put the cursor in the first input of these frames, type Alt+L, Alt+P, or Alt+O.

  5. Fixed a bug that developed in a recent update, where the export to EnergyPro 5 would not work unless you also had EnergyPro 6 installed.

3/6/2014 9.01.128

  1. Changed the logic that makes it so as you type in the room dimensions it also changes floor 1 and roof 1 dimensions so that it will not do that if there is only a space character in the floor or roof material input. Formerly, those inputs had to be totally blank for it to not do it.

  2. Added the ability to choose to export to EnergyPro 6 instead of EnergyPro 5.

1/9/2014 9.01.124

  1. Added a Summer Wet Bulb dialog that opens when you click the dropdown help button beside the summer wet bulb input on the General Project Data window. This new dialog lets you enter a desired grains difference value, and it will calculate a corresponding wet bulb temperature for you.

  2. Changed the way the calculations deal with partition walls when distributing system infiltration gains and losses to the rooms, so that such walls are included in the sum of the room's above grade gross wall area.

  3. Fixed a bug in the export to EnergyGauge USA, where the cavity and board R-values of walls was not always being included in the export.

  4. Modified the export to EnergyGauge USA, where the total number of bedrooms is determined by the number of rooms with just "bed" in the name instead of "bedroom."

9/24/2013 9.01.122

  1. Fixed a bug on the Duct Size Preview report, where the values in the Rough. Factor and Design L/100 columns were being rounded off to 1 decimal place.

  2. Made it so if you have entered any notes for a room on the Room Notes dialog they will be added to the Detailed Room Loads report.

  3. Made it so the "Actual" line under the "Cooling System Summary" section of the Room Load Summary report does not get included if you have unchecked the "Include this system's equipment on the Room Load Summary report" checkbox on the System Data window. Also made it so the "Cooling System Summary" section does not show up at all unless at least one of the necessary options to show the possible quantities below it is turned on.

8/14/2013 9.01.121

  1. Made a small correction to the calculation of the percentage of shading on a window due to an overhang in some cases.

  2. Fixed a bug in the Export to EnergyPro feature, where the exporting code would look for the custom mapping data files in the wrong folder. The custom mapping data files are only used if you customized the EnergyPro mapping by using the EnergyPro Custom Mapping window in Rhvac.

6/5/2013 9.01.118

  1. In the Bill of Materials component, fixed a bug in the automatic generation of the fitting parts list for certain types of takeoff fittings, where it was possible for the required quantity to be smaller than it should be in certain circumstances.

  2. Fixed a bug where the "Help on Current Window" toolbar button and menu item could become disabled under certain circumstances.

5/15/2013 9.01.117

  1. On the Detailed Room Loads report made it so the room length and width show as "n/a" if entered as 1 and the area, or if the project is in Drawing Board mode and the room is not a perfect rectangle with only 4 walls.

  2. Made it so the Drawing Board button and menu item are enabled even in projects that are not in Drawing Board mode. For such projects clicking the button shows a message box that explains that you have to switch the mode of the project using the Room Data Entry Mode function.

  3. Added items in the Help menu to take you to the page of links on our website for Bill of Materials and Proposal Maker videos. Also changed such menu items for Drawing Board and Manual D Ductsize to take you that same page that lists all the videos.

4/12/2013 9.01.116

  1. Fixed a bug in Manual D Ductsize and Tabular Manual D Ductsize, where if you had a system with multiple zones and you had set the Use CV if MultiZone input to Yes on the System Data window, trunks that feed only one zone would have the airflow from the peak calculation method assigned to them instead of the airflow from the average method.

4/5/2013 9.01.115

  1. Added an "Open Project from Recent Folder" item in the File menu, which lets you display the Open Project dialog already set to one of your recent project folders.

  2. Added a "Browse Recent Folder" button to the multi-project Project Explorer window, which lets you instantly change the list of project files to that of any of your recent project folders.

  3. Changed the folder location where certain temporary files are written while the program is running, in the case of the installation being the old, pre-2010 type.

  4. Fixed a bug that developed in one of the updates on the RPER 1.01 ACCA Design Review Form Data window, where it was not possible to change the picture in the Contractor's Signature input.

2/6/2013 9.01.113

  1. Added a "Num Pad" toolbar that lets you enter numeric values into inputs by clicking with the mouse.

  2. Made it so the EnergyGauge file export writes appropriate values for the cooling coil CFM entries.

  3. Fixed a bug on the ACCA review form report, where for heat pumps the heating capacity was sometimes incorrect.

12/6/2012 9.01.99

  1. Made some small changes to the ENB file for the Export to EnergyGauge USA FlaRes 2010 to accommodate version 3.0.03 of that software.

  2. Fixed a bug where if you had an active license for Bill of Materials and had entered ducts on the Tabular Manual D Ductsize window and had set the Takeoff Source of the project bill of materials to "TMDD" the takeoff from the ducts on the Tabular Manual D Ductsize window would be limited to the demo level (only 6 trunks and 6 runouts).

11/20/2012 9.01.98

  1. Fixed a bug where if you had any systems with no rooms in them that came in sequence before systems with rooms in them the return airflows for ducts in the higher system numbers would not get assigned correctly. This bug fix applies to ducts created in graphic Manual D Ductsize or on the Tabular Manual D Ductsize window.

  2. Removed the Minimize button from the Room Notes window, which was inappropriate for that window.

  3. Added over 500 US and Canada city records to the weather database from Table 1A in the latest edition of Manual J. Depending on the existing data for each city, we either added a new city record or edited the existing data.

  4. Made improvents to the fireplace options and inputs on the Winter Infiltration dialog, as well as to the F1 help information about fireplaces.

9/18/2012 9.01.90

  1. Fixed a bug where custom duct fittings you added were not being saved globally, but only in the current project.

  2. Added a "Merge from Project" button to the Custom Fittings dialog. This new button lets you copy any custom fittings that may be in the current project into your custom fitting database, so you can use those custom fittings in other projects. This feature can be useful when opening a project that was done on another computer and that had custom fittings added to it. You can now copy the custom fittings from that project into your own custom fitting database.

  3. Made improvements to the help file.

  4. Fixed a bug on the Hourly Room Net Gain report when the project is set to metric units, where the values for the data points were having the conversion from Btuh to watts done twice on them, making them too small.

  5. Removed the "Square ft. per Ton" line from the Check Figures section when you have both the "Show Net tonnage" and "Show Recommended tonnage" boxes unchecked on the General tab of the Select Reports dialog. Also made it so the "ft²/Ton" column on the Load Preview window and report is hidden when showing neither kind of tonnage.

8/17/2012 9.01.83

  1. Changed the text of the dropdown help for the Elevation Derating inputs. It now says that the normal thing is to leave those inputs set to a value of 1.0, and just let the program calculate the actual load without any derating, and then apply whatever derating factors the manufacturers recommend when selecting the heating and cooling equipment.

  2. Fixed a bug on the Winter Infiltration dialog where if you first selected "Manual J Air changes per Hour Method" and entered a number of fireplaces greater than zero, and then changed to one of the other infiltration methods the fireplace CFM from the "Manual J Air changes per Hour Method" option would still get added to the winter infiltration rate in the calculations.

  3. Fixed a bug on the Zone Summary Loads report when there are multiple zones in a system, where the lines showing glass sensible gains were showing the gain from the average load calculation rather than the peak.

7/5/2012 9.01.82

  1. Fixed a bug when entering rooms in Drawing Board, where if there were certain problems with the Room objects on a drawing it was sometimes possible for the program to not be able to correct those problems, and it would report various errors about the rooms.

  2. Changed "ACCA Design Review Form" to "RPER 1.01 ACCA Design Review Form" everywhere.

  3. Fixed a bug on the Zone Summary Loads report, where it was not showing a line for the AED Excursion load, though that load was included in the total being shown.

  4. For Drawing Board projects, made it so if the data on the Default Room Data window are incomplete when you drag and drop a room onto the drawing a message box will ask you whether you want to copy some generic defaults to the default room data before proceeding.

5/18/2012 9.01.80

  1. Fixed a problem in the Export EnergyGauge USA feature, where the ENB file produced, when imported into EnergyGauge USA, would cause the Temperatures tab on the Equipment tab to be blank instead of having the Programmable Thermostat checkbox.

  2. Fixed a bug that developed in the previous version, 9.01.78, which made it so some of the graphs, such as pie charts, would not show up on every computer.

5/11/2012 9.01.78

  1. Fixed a bug where if you had the Load Preview window open and had its Auto-Refresh feature turned on, and then on the Room Data window you opened the Sloped Ceiling Area Calculator, when you clicked OK on that dialog it would not always remember what you had just entered on it, and the roof's width and length on the Room Data window would sometimes remain unchanged.

  2. Fixed a problem in the Export EnergyGauge USA feature, where if you selected the 2010 format and there was only one space being written to the ENB file (either you selected the first option and there was only one system in the project, or you selected the second option and there was only one room in the project), partition walls would have their "Adjacent To" input in EnergyGauge USA blank. That was happening because the program was writing "Interior" for the ADJACENT_TO field in the ENB file, and EnergyGauge USA only allows Interior as an option if there are multiple spaces. The program now writes "Garage" if there is only one space in the ENB file.

  3. Made it so the ENB file created with the Export EnergyGauge USA feature includes much less extraneous information.

4/30/2012 9.01.77

  1. Fixed a bug in the Export EnergyGauge USA feature, where if you had two walls that were nearly identical in different rooms only one of them would get included in the ENB file.

4/27/2012 9.01.76

  1. Fixed a bug in the Export EnergyGauge USA feature when using the option to group rooms and materials in a system together, where the ceiling area on the Ceilings tab of EGUSA was incorrect.

4/25/2012 9.01.75 (Test Version)

  1. Fixed a bug in the Export EnergyGauge USA feature when using the option to export each room as a separate space, where if you had a wall that was blank or otherwise ignored on the Room Data window, followed by a good wall, and you had a window or door that referenced that good wall, the exported window or door in the ENB file would not be associated with the correct wall and could cause a "List index out of bounds" error in EGUSA.

  2. Made it so room names exported in the ENB file with the Export EnergyGauge USA feature only include characters that program allows for room names (letters, numbers and spaces). Also made it so room names in the ENB file are limited to 30 characters or less, since that is another limitation in EGUSA.

4/24/2012 9.01.74 (Test Version)

  1. Added "Save as Default" and "Load Default" buttons to the Reports tab of the Select Reports dialog. These buttons lets you save your report selection checkboxes in one project and later load those same selections in another project.

  2. Made it so the elevation adjustment factors do not show up on the Project report unless they are not equal to 1, and the cooling factors are not shown unless the "Show Recommended tonnage" checkbox on the General tab of the Select Reports dialog is also checked.

  3. Added an option to the Export EnergyGauge USA file that lets you create only one space (room) per system in the ENB file, and group together similar floors and roofs that are in the same system into one big floor or roof.

  4. In the Export EnergyGauge USA feature, when selecting one of the 2010 format options made it so the comment for each material includes the room(s) and item number(s) that were the source of each material in the Rhvac project.

  5. Added a "Permit Number(s)" input to the Project tab of the General Project Data window. The text you enter shows up on the Project report.

4/16/2012 9.01.72

  1. Modified the help file topic for the new EnergyGauge export feature.

4/13/2012 9.01.71 (Test Version)

  1. Added a checkbox to the Export EnergyGauge USA dialog that lets you create an ENB file in the format of the previous version of the program, which was called "EnergyGauge USA FlaRes2008."

4/10/2012 9.01.70 (Test Version)

  1. Fixed a bug in the export of the new version of the EnergyGauge ENB file, which could cause an "List index out of bounds" and other errors after importing the ENB file into in EnergyGauge and opening the project.

4/9/2012 9.01.69 (Test Version)

  1. Changed the way the CFM Per Runout input on the General Project Data window is handled in the calculations for the built-in duct sizing, so that the value entered serves as a maximum CFM per runout rather than a target average CFM per runout.

  2. Corrected the summer weather data for Knoxville, Tennessee.

  3. Changed the icons on the Room Data window's toolbar for the Create New Room and Insert New Room buttons in order to make them look completely different than the "R" button that is used to open the Room Data window.

  4. Modified the ENB file created for the EnergyGauge USA file export feature so that it can include multiple systems and multiple rooms.

3/1/2012 9.01.64

  1. Fixed a bug in the EnergyPro export, where rooms, windows and skylights with multiple occurrences were only being written to the EnergyPro file once.

  2. Added a line that shows exhaust CFM to the Total Building Summary Loads report and System Summary Loads reports.

  3. Made a minor correction to the SHGC values for the following window construction materials to match Manual J: 2A-w-o, 2A-a-o, 2A-v-o, 2A-f-o, 2A-w-d, 2A-a-d, 2A-v-d, 2A-f-d, 2B-w-o, 2B-a-o, 2B-v-o, 2B-f-o, 2B-w-d, 2B-a-d, 2B-v-d, 2B-f-d, 3A-w-o, 3A-a-o, 3A-v-o, 3A-f-o, 3A-w-d, 3A-a-d, 3A-v-d, 3A-f-d.

  4. Corrected the weather data for Fayetteville, North Carolina.

1/16/2012 9.01.63

  1. Added several Help buttons in various windows throughout the program. Also added links to some online instructional videos in various places in the program, including in the Help menu and on the Tabular Manual D Ductsize and Drawing Board windows.

1/12/2012 9.01.62

  1. Fixed a bug on the Wall object in Drawing Board, where if, before you divided a wall with the Divide Wall Here command you had set the Kneewall property to True, the new wall segment created by dividing the wall would have that property set to the default value of False instead of matching that of the original wall segment.

  2. Modified the "Repair and Compact Database" function to accommodate a file that is so corrupt that it does not appear to be a database, but not so corrupt that it cannot be repaired. Formerly, if a file was corrupt enough to no longer appear to be a database the program would refuse to even try to repair it. Now it will give you a warning on a Yes/No message box. If you click Yes the program will go ahead and try to repair it.

  3. Fixed a bug where if you added a new city on the Weather Database window while the General Project Data window was open the General Project Data's list of cities would not include your new city until you closed and reopened that window.

  4. Added a "Match Upstream Duct Size" property to ducts on the Tabular Manual D Ductsize window. This property shows up for any duct that is not a main trunk (the first one in the system).

  5. Added a cooling coil interpolater window that can be opened from the System Data window. The current window only deals with cooling data for air conditioners and air source heat pumps, which is the majority of cases, but we plan to expand this feature to include other kinds of data soon.

11/21/2011 9.01.57

  1. Fixed a bug on the Tabular Manual D Ductsize Layout dialog, where after you checked or unchecked any of the checkboxes the gray row at the top of the list would display incorrectly.

  2. Fixed a problem where if you used the "Copy to Clipboard" feature of the Load Preview window and then pasted it into an Excel spreadsheet, on certain projects an extra row would be created for any rooms that had "Not MDD" or "Not TMDD" notes in the Duct Size column. Also made it so only visible columns are copied to the clipboard.

  3. On the Tabular Manual D Ductsize window, made it so when you select an 11-B fitting for a duct it automatically sets the Material Option property to "None" instead of "Default," since a new item does not need to be added to the project bill of materials for this kind of fitting, which is just a bend in the flex duct.

  4. On the Tabular Manual D Ductsize window, made it so when you change the Material property for a duct by typing the first letter of the material ID (instead of using the dropdown help window), the Roughness property will automatically change to be appropriate for the new material. Made the same kind of change on the Tabular Manual D Ductsize Defaults window.

  5. Fixed a bug on the Tabular Manual D Ductsize window, where any duct you added to the "Individual Ducts" part of the tree would be flagged as invalid and would generate a warning saying that the duct would be ignored.

  6. Fixed a bug on the Tabular Manual D Ductsize window, where the Copy Fittings button and menu item were always enabled. Now they are only enabled when a duct with fittings is selected.

  7. Added an Insert Trunk feature to the Tabular Manual D Ductsize window. Clicking this button will insert a new trunk in between the current duct and the one just upstream of it (or downstream, on the return side).

  8. Added Cut Branch and Paste Branch buttons to the Tabular Manual D Ductsize window. This feature allows you to move a trunk and the ducts connected to it to a different location within the same system.

10/24/2011 9.01.54

  1. Added a "Save and Compact Project" item to the File menu. This feature is like "Save Project," but also performs a "Repair and Compact Database" on the project file.

10/21/2011 9.01.53 (Test Version)

  1. Fixed a bug on the System Data window, where if you clicked Copy System in that window's toolbar any recent changes you may have made to the current system just prior to clicking Copy System would not be included in the system data that gets copied to the clipboard.

  2. Made it so the "Show Net Tonnage" and "Show Recommended Tonnage" options on the General tab of the Select Reports dialog are complied with on the print preview version of the Load Preview. Formerly, which tonnages were shown were based on the state of the "Show Net Ton" and "Show Rec Ton" buttons on the Load Preview window itself.

9/12/2011 9.01.49

  1. Fixed a problem on the Equipment Cooling Loads window, where the cells in the grid that are for entering numeric values would accept non-numeric characters as well.

  2. Fixed a bug that could occur under certain circumstances in the calculation of Manual D Ductsize return duct cumulative losses and effective lengths, as described in its Readme file. Fixed the same potential problem in Tabular Manual D Ductsize.

8/25/2011 9.01.48

  1. Fixed a bug in the new feature added in the previous update that warns you when you have selected an infiltration option that does not match the building area. If the building area was over 3,000 square feet and you had appropriately selected an option in the 5th column, an incorrect warning would be added to the Evaluation of Project window saying that the column was not correct.

8/23/2011 9.01.47

  1. Added a warning to the Evaluation of Project window when the infiltration method chosen on the Winter Infiltration dialog is "Manual J Air Changes per Hour Method" and the selected column is wrong for the entered building area. Did the same for the Summer Infiltration dialog.

  2. Fixed an obscure bug where if you imported an Rhvac 8 project in which you had never opened the System Data window, and you also never opened the System Data window in the project after you imported it into Rhvac 9, the Evaluation of Project window would show a "No current record" error.

  3. Corrected the name of Elizabeth City, North Carolina, which had been only "Elizabeth."

  4. Corrected the weather data for Gainesville, Florida to match Manual J.

  5. Fixed a bug on the Manual D Ductsize Data report, where if the Return Main Trunk object had its "Add Return Loss to Supply" property set to False (which is not common) the total effective length of the supply would be incorrect. Also fixed a bug in the same circumstance, where the line showing the return loss added to the supply would incorrectly show the loss of the return side instead of zero.

  6. Fixed a problem with the self-extracting setup file available on the web, rh9setup.exe, where if a file named Setup.exe was located in the same folder as rh9setup.exe the Setup.exe in the same folder would be run instead of the Setup.exe contained in rh9setup.exe.

7/15/2011 9.01.46

  1. Fixed a bug that was introduced in a recent version, where if you selected all the reports on the Select Reports window only the default set of reports would be included.

7/12/2011 9.01.45

  1. In the export to EnergyGauge USA, changed the way R-values are written for the block walls that have no framing but do have board insulation (category 13A), so board insulation is read as being interior instead of exterior. The help for EnergyGauge USA explains that its "Wall Cavity Ins. R-Value" input can also be used for the interior insulation when you have concrete block with interior insulation.

  2. Fixed a bug in the Global Material Change feature for projects done with Drawing Board, where the description for glass items would stay the same when you performed a change.

6/30/2011 9.01.44

  1. Corrected the weather data for Shreveport, Louisiana to match Manual J.

  2. Added thousands separators and units to the line that shows equipment total capacity on the Room Load Summary report.

  3. Fixed a bug that developed recently on the print preview version of the Building Rotation Duct Sizes report, where the room CFM values for each rotation were the same value, which was that of the unrotated building. Also went back to performing the rotation calcs twice during generation of the print preview if both rotation reports have been selected, which is necessary because of the option on Select Reports where the system air type can be forced to Auto for the building rotation report.

  4. On the Rotate or Mirror Rooms dialog, made it so the Building Orientation direction on the General Project Data window is only updated if you have selected all rooms for rotation or mirroring. The message box displayed after the rotation tells you whether or not the orientation direction has been updated.

6/22/2011 9.01.42

  1. Changed the error that gets displayed for a duct in the Evaluation of Project window when the sizing method is set to use the schedule, but the schedule has all zero values entered. Formerly, the error would say, "Subscript out of range," but now it says, "Sizing method is "Schedule," but duct schedule has all zero sizes."

  2. Fixed a bug on the Room Data window when using the F5 and F6 functions ("Copy Above Or Default And Room Dimension" and "Insert Only Default Room Data"), where the description of the current material would not get updated to be that of the material from the default room. This bug made it so the last part of the material description shown on the "Summary Loads" reports could be incorrect.

  3. Added the formulas for calculating duct surface areas to the F1 help file, for situations where you want to hand calculate the duct surface areas to enter on the Duct Load Factors dialog.

6/17/2011 9.01.41 (Test Version)

  1. Made it so if you associate Rhvac version 6 or 8 project files (extension "RHV") with Rhvac9.exe the program will import the project, treating the file as if you had selected it with the "Open Previous Version Project" feature.

6/9/2011 9.01.40

  1. Changed the "Not MDD" message on the Load Preview window to "Not TMDD" when the message applies to the Tabular Manual D Ductsize window rather than graphic Manual D Ductsize.

  2. Fixed a bug on the "Duct Size Preview" and "Building Rotation Duct Size Preview" windows where the size for the supply main trunk would show up as minus one ("-1") if that duct had been defined using Tabular Manual D ductsize or graphic Manual D Ductsize.

  3. Fixed a bug where if you had created ducts with the Tabular Manual D Ductsize window and had selected to print one or more of the Tabular Manual D Ductsize reports, and you also selected to print the Room Load Summary report, the number of runout ducts per room shown on the Room Load Summary report would be higher than it should be.

  4. Modified the reporting code so the building rotation will only be performed once during report generation even if you have both of the rotation reports selected.

  5. Made it so fewer reports are selected by default when starting a new project using the Blank Project icon. Also made it so each of the sample projects have fewer reports selected than they did before.

5/17/2011 9.01.38

  1. Fixed a bug when exporting a project to EnergyPro, where if you selected "Existing" as the Surface Type the assemblies assigned to each of the materials would be incorrect.

5/11/2011 9.01.37

  1. Fixed a bug where if you had used a custom basement wall with more than 2 characters after the final dash (which indicates the wall's floor depth), when exporting to resCHECK the floor depth would be assigned a value of zero.

  2. Made it so when you export a file to Rem/Rate the floor depth of any custom basement walls will be assigned.

  3. Fixed a bug where any text you entered for the Comment field on the Cooling tab of the Equipment tab of the System Data window would not get saved.

  4. Fixed a bug where even if you checked the box for the "Show EER for air conditioners and air source heat pumps on reports" option on the Rhvac Options dialog the reports would still only show the SEER for those units.

  5. Made it so the cooling and heating efficiency values are shown more thoroughly on reports. For example, the efficiency of a two speed furnace now gives the AFUE of both the high and low speeds.

4/27/2011 9.01.34

  1. Made it so when you create a new room on the Room Data window it always sets the system and zone number inputs to that of the most recent room you had been viewing. Formerly it only did that if you had the "Copy all default data to rooms created in Room Data window mode" option on the Rhvac Options dialog unchecked.

  2. Fixed a bug in the export to EnergyPro, where each floor was not always being included.

  3. Fixed a bug in the export to EnergyPro, where skylights were not being included in the export.

  4. Added an "EnergyPro Export" dialog that opens when you export to EnergyPro. This new dialog has an option that lets you set EnergyPro's Surface Type input ("Existing," "New," "Altered," or "Removed") for all of the materials and rooms exported.

4/18/2011 9.01.31

  1. Reduced the time it takes to generate the reports when the Print Preview window is not open yet.

  2. Fixed a bug on the Winter Infiltration dialog, where if you selected the "Foam (as recommended by foam manufacturers)" option (0.1 air changes per hour) and the Sync checkbox at the bottom of the window was checked, the summer infiltration value would get set to a value other than 0.1. Fixed the same bug on the Summer Infiltration dialog.

  3. Fixed a bug where the Mirror option on the Rotate or Mirror Rooms dialog did not work.

  4. Added a Register Sizing Data property to main trunks on the Tabular Manual D Ductsize window. Clicking the button beside this property opens a dialog that lets you enter register widths and heights that correspond to ranges of CFM values. Any runouts in the same system that have their Auto Assign Register Size property set to True will have their Register Width and Register Height properties automatically sized according to the data on that dialog.

  5. Added 11 properties to the left side of the Tabular Manual D Ductsize Defaults dialog. Including these properties gives you more control over the default properties assigned to new ducts you create, and it makes it faster to make changes to multiple ducts at one time.

4/6/2011 9.01.28

  1. Added Copy Fittings and Paste Fittings functions to the Tabular Manual D Ductsize window's toolbar and right click popup menu. This feature lets you copy and paste just the fittings from one duct to another. The clipboard for this feature is separate from the clipboard used for the Copy Duct and Paste Duct functions.

  2. Made it so when you select a Group 13 fitting, in either Graphic or Tabular Manual D Ductsize, the device pressure loss is adjusted to account for the velocity of the duct compared to the reference velocity of 900 FPM for the Group 13 fittings. This change corrects a situation where the back-calculated equivalent length for one of these fittings could be very high if the velocity for the duct was very low.

  3. Made it so you can type a feet and inches value into the Length property for a duct on the Tabular Manual D Ductsize window. Remember that in inputs where you can type feet and inches, you can type the number for feet, then a dash, then the number for inches.

  4. Fixed a bug where the total effective length shown in a few places in the program and its reports was sometimes based on the route with the longest effective length rather than the route with the highest pressure loss. The route with the highest pressure loss is usually the one with the highest effective length, but not always. So the program now always chooses the route with the highest pressure loss when it refers to the total effective length of a duct system.

4/1/2011 9.01.26

  1. Changed the wording of the warnings displayed in the Evaluation of Project window when you have a material with a zero U-value.

  2. Made it so the Evaluation of Project window remembers its size and position better, so it will stay where you put it.

  3. Added "MDD" or "TMDD" to the beginning of any errors or warnings from graphic Manual D Ductsize or Tabular Manual D Ductsize that are shown in the Evaluation of Project window.

  4. Made it so if the fan external static pressure entered on the Tabular Manual D Ductsize window is lower than the total system static pressure loss the "Design Friction Rate Status" will say, "ESP Low." Also added a warning when the design friction rate status is not "OK" on that window, and for duct systems entered on graphic Manual D Ductsize.

  5. Fixed a bug where if you unchecked the "Display values in decimal feet when using English units" option on the Rhvac Options dialog some values would not show up on the Tabular Manual D Ductsize window, such as duct lengths and fitting equivalent lengths.

3/23/2011 9.01.25

  1. Fixed a bug that could happen after using the "Duplicate Room" function in Drawing Board, where the project could then have a persistent error number 3021, "No current record." Also made it so any project having this problem is automatically repaired once you open it in this version.

3/22/2011 9.01.24

  1. Added a Sloped Ceiling Area Calculator dialog, which opens by clicking the item in the dropdown help for the roof/ceiling's Width and Length inputs. This dialog lets you enter dimensions for a room's sloped ceiling, and calculates the resulting area of the ceiling. The area is copied to the roof/ceiling's Width input, and the number 1 is copied to the Length input.

3/16/2011 9.01.21

  1. Fixed a bug that would happen during the import of Rhvac 6 or 8 projects, where the Comment for the cooling equipment entered on the System Data window would be changed to say, "0" (zero) instead of the original text.

  2. Fixed a bug on the System Equipment Data and the equipment part of the System Room Load Summary reports, where the efficiency values for heating and cooling did not match those shown on the Equipment tab of the System Data window. Also fixed a bug where if the unit was two speed (two stage furnace, etc.) the capacity shown on those reports was the value from the field used to save single speed capacity rather than the field for a two speed unit's high speed capacity.

3/14/2011 9.01.20

  1. Fixed a bug on the Room Data window where the F5 function for copying the above glass or door was copying the item from room 1 instead of from the current room.

  2. Fixed a bug in the export of EnergyGauge USA files where if a custom wall's description included the insulation R-value and the "R-Whatever" text was at the end of the description the program could lock up.

  3. Improved the mapping of glass types for custom windows when exporting to EnergyGauge USA.

  4. When exporting to EnergyGauge USA, made it so each error or warning only appears once in the list.

  5. Made it so when exporting to EnergyGauge USA walls that contain windows with differing overhangs are exported as different walls rather than grouping them together.

3/11/2011 9.01.19

  1. Updated the menu, "Help | Elite Software on the Web | Rhvac Update Page" to go to the version 9 recent history page.

  2. Technical changes regarding how materials on the Room Data window are read and written.

  3. Made it so the ACCA design review form can be printed for each system in the project.

  4. Fixed a bug on the ACCA design review form where if all the rooms were heating only the system CFM would still be shown in the Cooling CFM line. The same problem was fixed when rooms are all cooling only.

3/7/2011 9.01.11

  1. Fixed a bug on the Global Material Change dialog when opened from the Room Data window, where the bottom input for the floor material (the material to change the floor to) would not change after you selected a floor on the Floor Material dialog.

  2. Fixed a bug on the Room Data window, where if you had the "Exclude partition from wall lengths for Floor 1 perimeter calc" option checked on the Rhvac Options dialog, when you pressed F5 to insert the default floor into the Floor 1 row, the perimeter value inserted would not include the first wall's length, even if that wall was not a partition.

3/4/2011 9.01.9

  1. Added options for the ACCA Design Review Form so on the Select Reports dialog you can choose between the form's headers referencing IRC (International Residential Code) or UMC (Uniform Mechanical Code).

  2. Updated the ACCA Design Review Form report to the "8 Mar 10" version. Also added a note at the bottom of the page that says that the form was generated by the Rhvac program.

  3. Modified the ACCA Design Review Form report so that everything is compacted toward the top of the page slightly, in order to make it so the text at the bottom of the report will print even on older printers with smaller printable areas.

  4. Fixed a bug where if you had a room with a system number greater than the number of systems you had defined on the System Data window the Evaluation of Project window would show a fatal error that said, "Update or CancelUpdate without AddNew or Edit."

  5. Fixed a bug on the new Equipment Cooling Loads window, where if you opened it from the Default Room Data window it would not save your data.

  6. Added a Notes input to the bottom right corner of the Room Data window. Clicking the dropdown help button opens a new Room Notes window where you can save formatted text and/or graphics for each room.

  7. Fixed a bug when creating a new room, where the "Add Default Floor To New Rooms" and "Add Default Roof To New Rooms" buttons were being ignored. Applies to rooms created on the Room Data window, the Drawing Board window, and the Project Explorer window.

  8. Fixed a bug on the toolbar on the Room Data window, where the "Insert Only Default Room Data" was not being enabled for all of the inputs that can copy data from the Default Room Data window.

  9. Fixed a bug where several windows did not have cut, copy and paste functionality, including the Room Data and System Data windows.

  10. Fixed a bug in the Equipment Cooling Loads part of the Detailed Room Loads reports, where if the project was metric the latent load shown for individual items was in Btuh rather than watts.

  11. Fixed a bug in the Equipment Cooling Loads part of the Detailed Room Loads reports, where if you changed a room's sensible or latent equipment load by typing it into the inputs on the Room Data window itself after having entered one or more specific items of equipment on the Equipment Cooling Loads window, the "Miscellaneous Equipment" row on the report would still have the old values.

  12. Fixed a bug where the F5 and F6 functions ("Copy Above or Default and Room Dimension" and "Insert Only Default Room Data") on the Room Data window did not always work for Doors.

2/25/2011 9.01.5

  1. Modified the way project files are updated upon opening so that a complete rebuild is performed if the project needs updating. Any of your existing projects you open in today's version will undergo this automatic rebuild when you open them.

  2. Replaced the dropdown help for the sensible and latent equipment inputs on the Room Data window with a new popup window named, "Equipment Cooling Loads." This new window lets you enter multiple items that contribute the the sensible and latent equipment loads of the room, including diversity factors. The dropdown help for each item has a list that includes items from Manual J's Table 6B.

  3. Fixed a bug where if the current project had no rooms and you clicked "Evaluate Project" the Evalaution of Project window would include an error that said, "Subscript out of range."

  4. Fixed a problem in the Autoload Rhvac 9.rh9 project that gets installed in a first time installation, where the duct insulation values shown on the Duct Load Factors dialog were set to zero instead of 6.

2/22/2011 9.01.1

  1. Fixed a bug on the Radiant Floor Properties dialog when opened from the Room Data window, where the dropdown help window for the room number was not being filled up with the room numbers and names.

  2. Fixed a bug on on the Room Data window, where the Evaluate Room function would show an error in the Evaluation of Room window that said, "Subscript out of range."

  1. Fixed a bug on the Room Data window, where pressing F5 to copy the above component for floors and doors did not work.

  2. Fixed a problem on the ACCA Design Review Form report where it was possible for the default value for the number of bedrooms to not include some bedroom names. Now any room containing "bed" will be counted as a bedroom. If the count is wrong you can always override the default by filling in the Override column on the "ACCA Design Review Form Data" window.

  3. Fixed bugs on the ACCA Design Review Form report where the default values for the cooling equipment's sensible capacity, latent capacity and total capacity were coming from the wrong fields.

  4. Fixed a bug on Drawing Board, where if a Room object's Floor Material (Instrinsic) property was blank and you had drawn a Floor object in the room, the U-value and other properties of the Floor object would get set to zero or blank. Fixed the same problem for roofs.

  5. Added the ability to set the surface area for a scenario on the Duct Load Factors dialog to that of ducts entered on the Tabular Manual D Ductsize window.

  6. Added duct surface area and duct load factor scenario columns to those available on the duct grid on the Tabular Manual D Ductsize window.

  7. Fixed a bug on the Tabular Manual D Ductsize window where if you were editing a duct or fitting property in the center or right grid, and the edit box was still visible, and you then clicked a different duct on the duct grid your new property value would get saved to the new duct instead of the one selected previously.

  8. Made it so only a few of the columns are shown by default on the duct grid on the Tabular Manual D Ductsize window. Click the Tree Layout button to see more columns.

  9. Made it so the edit box is visible and on the Contractor input upon first opening the ACCA Design Review Form Data window.

  10. Made it so when you click any column on a row on the ACCA Design Review Form Data window the edit box is shown in whichever column is editable for that row.

2/9/2011 9.00.72 (Beta 3, First Public Beta)

  1. Fixed a bug in Drawing Board, where a skylight could generate an inappropriate warning saying that the ground reflectance entered for the glass was too low.

  2. Made it so descriptions of materials used in the project are saved in the project file itself, which makes it so when you open a project that someone else entered that has custom materials that are not in your custom material list the descriptions of those custom materials will be shown on the reports.

  3. Made it so the first supply arrow node is selected upon first opening the Tabular Manual D Ductsize window.

See the Readme file for the private beta history before this point.
