Energy Audit is Windows software for calculating monthly and annual heating and cooling costs for residential and light commercial buildings, with the ability to simulate nearly all HVAC system types, analyze appliance and domestic hot water energy use, and handle both simple and complex utility rate structures. It references ARI and GAMA equipment data (included) to align performance and cost projections, generates concise graphical reports with color pie, bar, and line charts, and supports economic comparisons of HVAC systems, including loan and lease analyses for purchase decisions. Energy Audit links with RHVAC and CHVAC for streamlined workflows from load calculation to energy/cost analysis, and includes a heat pump balance point graph and optional pictures for numerous equipment models in reports.
