The Commercial Load Calculation Software quickly and accurately calculates the maximum heating and cooling loads for commercial buildings, according to the company. Cooling loads can be calculated with either the Cooling Load Temperature Difference method or the Radiant Time Series method. The program allows for 50 zones, which can be grouped into as many as 50 air-handling systems. The software 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 2,000 cities around the world. Comprehensive reports list the general project data, detailed zone 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. It is powered by Elite Software's Commercial HVAC Load Calculation (CHVAC) software.
