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. There is also provision for editing the weather data as well as adding data for other cities.

In addition, it can look up outdoor design weather data for over 2000 cities located around the world. Chvac automatically looks up all cooling load and correction factors necessary for computing loads. The program allows an unlimited number of rooms which can be grouped into as many as 100 air handling systems. The cooling loads can be calculated with either the CLTD method or the new RTS (Radiant Time Series) method.
