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
Fire Protection CAD Details just $350
Fire Protection CAD Details is a collection of 151 fully editable .dwg files that can be used with virtually any CAD package. Unlike other CAD packages which have only details, Fire Protection Details also includes standardized schedules, notes and symbols.  The Fire Protection Details are only $350.  See a complete listing and sample detail drawings at 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.
Utility Rate Competition
Many states in the U.S. now allow electric power consumers to choose their electric utility supplier.  The Elite Software AUDIT program is especially good for showing the savings a business can enjoy with a reduced electric power rate.  AUDIT can evaluate not only heating and cooling operating costs, but miscellaneous appliance and equipment energy use as well.  In some states, even home owners can benefit from a switch.
It is often difficult to locate and evaluate competing utilities for a given region.  In Texas, a company called Energy Optimizers Inc. specializes in locating the best power option for you.  And for other states, they can advise you on how to research the issue yourself.  For more details, visit or call them at 469-519-1061.
Software Training
Three companies located in different areas of the United States offer training on Elite Software programs.  The companies are listed in alphabetical order below with the name of their main trainer and a summary of their company's capabilities.  Each of these companies will travel if needed and some of them already have a schedule of training seminars.  See their respective web sites for details.
