New Product Preview Advertising Section Free ventilation software for ASHRAE 62-2004 compliance RenewAire has upgraded its ventilation software suite to include an easy-to-use ventilation calculator. By filling in an on-screen form you can choose between ASHRAE 62-1999 and the recently adapted 62-2004 version. Drop-down menus allow selection of occupancy type. When using the 62-1999 version you may enter either the number of occupants or square footage of floor space. For the 62-2004 version you must enter both the number of occupants and the square footage, and the type of heating or cooling system (which determines how well the air mixes in the space, i.e., the ventilation effectiveness). Individual zone ventilation requirements are analyzed in this method providing a ventilation rate for both required exhaust and minimum fresh air supply. The project report may be saved, edited and printed to document code design compliance. The RenewAire ventilation software suite also includes a psychrometric calculation and charting program, weather data for major cities in the USA and Canada and the latest versions of RenewAire’s ventilation load calculator and annual savings calculator. The last two programs allow analysis of the performance of the full line of RenewAire static-plate energy recovery ventilators based on the product’s ARI-Certified ability to efficiently transfer heat and humidity. This tool will help identify ventilation requirements and an efficient design solution with an integrated approach.
