Do you need to meet the requirements of IECC (International Energy Conservation Code) and ASHRAE Standard 90.1 or other area-specific codes and want to follow a prescriptive or trade-off path? COMcheck™ software will meet your needs! It is free software from the US Department of Energy designed to make it easy for builders, designers, and contractors to determine whether new commercial or high-rise residential buildings, additions, and alterations meet the requirements of the IECC and ASHRAE Standard 90.1 and area-specific codes. COMcheck™ is appropriate for trade-off calculations for insulation, windows, lighting, HVAC, and hot water heating.

The COMcheck™ building envelope reporting software is free, but the learning curve is steep. Call E3 Power today for a free COMcheck™ services quote in Denver CO. My price on a building can be as low as $200 for COMcheck™ compliance and consulting services. All I need to start is a digital copy of your building plans. I complete the take offs using Sketch-up™ and enter the data into COMcheck™. Turnaround time is usually two business days.
