Rhvac Version 9 Recent Update History

Version Changes

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."

2/18/2011 9.01.0 (Official Release)

Original Upgrade Price Schedule from February 2011:

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.
