If you work in HVAC design, one tool comes up over and over—HAP, or the Hourly Analysis Program. It is used by engineers widely to calculate cooling loads, heating loads, and energy performance of buildings. As many of the calculations made in HVAC design are crucial to that particular system, HAP provides structured work to ensure correct sizing of systems. The software may be technical in an appearance, but understanding the general HAP guidelines will make your work a lot easier.

These guidelines serve as a roadmap for preparing input data, selecting equipment, and interpreting results. With the right approach, even someone new to HVAC can start designing smarter systems.
