Residential Loads Analysis
Rhvac Update with New MJ8 Addendas and Software Links
ACCA has been continuously improving the MJ8 calculation procedures with four new addenda, A thru D, that have been released over the past few months.  As of the time of this writing (10/01/2004), Rhvac is the only load calculation software available that includes all four addenda.  A summary of what the addenda addressed is shown below.  Complete details on the addenda can be seen on this ACCA web page. 
Addendum A:  This is a "Do's and Don'ts" list on how to use MJ8 procedures. The Rhvac Help window now includes the list of from this addendum.
Addendum B:  This implememts an Hourly Fenestration Gain (HFG) procedure for room level loads whenever you have rooms in multiple zones within the same system. System Concept Warnings were also included whenever a system has "excursion" as a result of not having adequate exposure diversity.

Addendum C: Gives you much more control over duct loads and has an easier to understand and more flexible set of inputs.
Addendum D: Provides more options to let you define the envelope construction tightness when determining infiltration. Also provides a more accurate methodology of accounting for the effect of fireplaces on infiltration.

New Link to REM/Rate:  Many of you in the home energy rating business use a program called REM/Rate.  Click on this link for details on this program.  Rhvac can now export project data for immediate use in REM/Rate.
New Link to ResCheck:  Many states require the use of a Department of Energy program called ResCheck.  Click on this link for details.  This program requires input data similar to Rhvac. To speed the process, Rhvac can now export project data for immediate use in ResCheck.
Current users of Rhvac version 8 can obtain a free update by downloading the Rhvac update from this web page.  Rhvac 8 users can also obtain a new CDROM for $25 plus shipping.The update cost for Rhvac6 users is $149 plus shipping.  Call 800-648-9523 to order or go online to our order page to place your order.
AutoCAD Links to Ductsize, Fire, S-Pipe, and D-Pipe
AutoDesk, the makers of the popular AutoCAD drafting software has released a new package called AutoDesk Building Systems 2005 (ABS).  The ABS package provides architectural drawing features along with the ability to draw hvac, plumbing, mechanical, and electrical systems.  AutoDesk is offering various priced upgrades to people who already own different combinations of AutoCAD, Archictural Desktop and other existing packages.  See the following webpage for more details on the ABS package.
From scratch, ABS typiclly has a street price around $5,500.  Depending upon what AutoDesk products you already own, an upgrade to ABS (called a cross-grade by AutoDesk) could be as low as $1,000.
Besides advanced drawing capabilities, a major benefit of ABS is that it provides links to four of Elite Software's programs: Ductsize, Fire, S-Pipe, and D-Pipe.  Each of these Elite programs can receive data from a drawing done with ABS, perform calculations, send appropriate sizing data back to the drawing.
Only the Static Regain version of Ductsize and the1,000 sprinkler capacity version of FIRE have this new link capability.  Existing users of those programs can obtain a free update by downloading an update file from www.elitesoft.com Those of you who don't own those programs but would like to investigate further should download demos of those programs from Elite's web site and also contact your local AutoCAD dealer to receive a demonstration of ABS 2005.
New Chvac7 Release Incorporates RTS
Elite Software is pleased to announce the release of Chvac7 for commercial hvac load calculations which incorporates the new ASHRAE Radiant Time Series (RTS) calculation method along with retaining the CLTD method for use of comparisons.  The new, sophisticated RTS method provides numerous improvements over previous calculation procedures such as TETD, CLTD, and TFM methods.
The primary benefit of the RTS method is improved accuracy because it factors in the delayed effect of both radiant and conduction heat gains.  In addition, RTS offers greater sensitivities to material properties as new inputs are provided for absorptance, emittance, and other factors known as Delta R and h (outside).  These new inputs allow the designer to account for subtle changes in roof and wall sections that can significantly affect cooling loads.
Even glass has additional new inputs to allow for greater sensitivity in the RTS calculations.  Rather than just using one average SHGC (solar heat gain coefficient) for load calculations, the RTS method allows for varying SHGC values at different solar angles.
The new Chvac7 release contains many more new features beyond just adding the RTS calculation procedures.  For a complete list of the new features please visit our newsroom.  Current users of Chvac version 6 can upgrade to Chvac7 for only $149 plus shipping.  Call 800-648-9523 to order or go online at our order page to place your order.
For those of you who might like to test the update before buying it, you should download and install the Chvac7 functional demo.  It will coexist with a full version Chvac6 installation with no interference.  If you like how the Chvac7 demo works, you can place your order to have it unlocked into the full version.
Article on RTS in ASHRAE Journal - January 2004 Issue
Steve Bruning wrote a comprehensive article entitled, "A New Way to Calculate Cooling Loads," that appeared on page 20 in the January 2004 issue of the ASHRAE Journal.  This article gives a comprehensive explanation of the principles and methods used in the RTS procedures.  This article can also be downloaded for a small fee from this ASHRAE web site link.
Collection of Electrical Tools
New Program - Electrical Tools just $249
Electrical Tools (E-Tools) is a new program that provides 14 common electrical calculation and data look-up tasks. These tasks include wire sizing, conduit sizing, motor equipment sizing, panel sizing, lighting requirements (in metric or English units), current to power conversion, Ohm's Law calculator, capacitor sizing for power factor correction, voltage drop, short circuit, and the quick look-up of many electrical formulas and conversion factors. Results are instantly displayed on the screen as data is entered.  See more details and download a functional demo at the E-tools description web page.
HSYM Hydraulic Only Analysis Version just $495
Hsym is a program for modeling chilled and hot water hvac piping systems.  The full version of Hsym for $995 performs both a hydraulic analysis with flows, velocities, and pressures, and a thermal analysis such that all entering and leaving water and air temperatures are calculated.  It is this thermal analysis capability that sets Hsym apart from all its competitors.
However, the thermal analysis also requires many additional inputs that designers sometimes do not want to deal with if they are interested in just a hydraulic analysis to see if desired flow rates can be achieved with the given pipe and pump sizes.  A hydraulic only analysis is much easier for a program to solve, so that is why it only costs $495.
The hydraulic only analysis differs from the full analysis in that the goal of the software is to achieve desired flow rates for the given pipe network and flow control valves.  In the full analysis version of Hsym, the primary goal is to achieve the desired air temperatures with the given water temperatures.  Flow rates are adjusted to achieve the air temperature goal. The full analysis version of Hsym thus performs both a hydraulic and thermal analysis of a chilled/hot water piping system.
If the hydraulic only analysis version of Hsym is purchased for $495, the full analysis version can be obtained at any later time by just paying the difference in price of $500.  See the HSYM description web page for more details and a functional demo of Hsym.  Existing Hsym users need a new .wef file to use the new release of HSYM, which can be requested free of charge by e-mailing sales@elitesoft.com
Three CAD Detail Packages just $350 each
Hvac CAD Details, Plumbing CAD Details, and now the newest addition Fire Protection CAD Details are a great addition to your drawing library.  These fully editable .dwg files that can be used with virtually any CAD package. Unlike other CAD packages which have only standard details, these details packages include standardized schedules, notes and symbols.  For a complete listing and sample detail drawings of the newest release see the Fire Protection Details web page.  See also the Plumbing CAD Details at this web page, and the HVAC Details packages at this web page.
