The newest upgrade to its Hourly Analysis Program (HAP) improves project estimates when designing heating and cooling systems, the company says. Windows®-formatted HAP 4.03 allows estimation of heating-cooling loads for commercial buildings, as well as hourly energy and operating costs. The software models conditions in all rooms of the building, considering windows, doors, skylights, floors, and other variables, in all times of day and seasons.
