Elite Software offers over 30 programs for all kinds of mechanical, electrical, and plumbing design applications. This monthly newsletter will announce new software, tradeshow events, and tips on using existing software. See previous newsletters here.

Chvac is a commercial HVAC load calculation program based on the ASHRAE CLTD/RTS calculation procedures, which comply with ANSI Std. 183.  See details on Std. 183 here. Elite Software has created new Chvac videos, some interactive and some continuous play with voice and sound. Here is a link to the new videos. The continuous play videos are also available on the new Elite Software YouTube channel, as seen here.

The most recent video for Chvac involves how to use the gbXML file import and export feature. A gbXML file is a file created from a CAD drawing system like Revit or AutoCAD MEP. A building drawing created in one of these advanced drawing systems contains building information needed for a load calculation such as roof, wall, and glass areas plus quantities of lights, people, equipment loads. This information within the drawing file can be exported to a special gbXML file that can be read and imported into the Chvac program. Using this feature saves you many hours of time, since you don't have to type into Chvac all these room data details.

The gbXML files can be quite variable in what they contain. To better handle this situation, several new import options have been provided in a free update to existing Chvac 8 users. Read more details about what a gbXML file is and download some sample gbXML files.

If you have any questions, please feel free to call 800-648-9523 or 979-690-9420, or send email to info@elitesoft.com.

Chvac - Commercial HVAC Load Calculations

Chvac has been an industry leader in commercial HVAC load calculation software since 1979. Try Elite Software's flagship program today and see why so many commercial designers are choosing Chvac. Get both Chvac and EnergyPro (which Chvac links to) and you'll have the most powerful, user-friendly commercial load calculation/energy analysis combo on the market.

Chvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings, and is accepted for Std. 183 submittals. The cooling loads can be calculated with either the CLTD method or the newer RTS (Radiant Time Series) method. The program allows up to an unlimited number of rooms, which can be grouped into as many as 100 air handling systems. Chvac automatically looks up all cooling load and correction factors necessary for computing loads. In addition, it can look up outdoor design weather data for over 2000 cities located around the world. There is also provision for editing the weather data as well as adding data for other cities.

Comprehensive reports list the general project data, detailed room loads, air handler summary loads, outside air loads, total building loads, building envelope analysis, tonnage requirements, CFM air quantities, chilled water flow rates (if applicable), and complete psychrometric data with entering and leaving coil conditions. Other outstanding features include ASHRAE Standard 62 analysis, automatic building rotation, 360 degree wall orientations, tilted glass, exterior shading, internal operating load profiles, variable indoor design temperatures, people diversity, pretreated outside air, seasonal infiltration and ventilation rates, reheat loads, duct gains and losses, and return air plenums.
