In many new commercial and institutional buildings, heat pump systems can provide significant energy performance advantages relative to conventional HVAC systems.

HPAC is a software tool that provides rapid assessment of heat pump systems for a specific set of building parameters with minimum input requirements. HPAC aims at supporting energy management consultants and building engineers in justifying a comprehensive Heat Pump project feasibility study.

Tool Features

  • Compares pre-screened Heat Pump system options to base case HVAC systems for new commercial and institutional building constructions or major retrofits
  • Provides best options on basis of GHG reduction, Net present value, simple payback
  • Uses  DOE 2.1 building energy simulations results and built-in algorithms to adjust simulation results to user input
  • Enables the evaluation of the following options:
    • Heat Pump: Air source, geothermal, water loop, heat recovery chiller, variable refrigerant flow
    • Building types: Hospital, school, long term care, small and large office, multi-residential units
    • Locations: Major cities across Canada


  • Funding: Office of Energy Efficiency (OEE) and Office of Energy Research & Development (OERD)  
  • Participation in software development: Caneta Research

HPAC was developed following consultations with experienced engineering consulting firms in the buildings sector in Canada. It is part of a broader CanmetENERGY initiative to increase awareness of available heat pumps technologies for commercial and institutional buildings in Canada and to reduce greenhouse gas (GHG) emissions.
