Carrier HAP (Hourly Analysis Program) is Carrier Corporation’s proprietary building energy simulation and HVAC design software that integrates load calculations, system modeling, and equipment selection into a single platform. HAP performs hourly energy simulations to predict annual energy consumption and demand profiles for commercial buildings. The software includes Carrier equipment performance data, enabling direct specification of company chillers, rooftop units, and controls.
Technical Capabilities
HAP calculates heating and cooling loads using ASHRAE design day methodology, then performs hourly energy simulations across annual weather profiles. The software models central plant equipment including multiple chillers with part-load performance curves, condenser water loops, and pumping strategies. Users can evaluate demand-side management, thermal storage, and alternative refrigerants.
Market Position and Adoption
Carrier HAP serves mechanical contractors and engineering firms designing large commercial and institutional HVAC systems. The platform’s integration with Carrier equipment specifications streamlines design communication with equipment manufacturers. HAP competes with Trane Trace and EnergyPlus-based platforms, offering manufacturer-specific advantages and equipment data for projects specified to Carrier equipment.
