The LEEP Air-Source Heat Pump (ASHP) Sizing and Selection App is a tool for HVAC designers and contractors to use with builders and homeowners in both new-builds and retrofits of existing homes. This tool follows Natural Resources Canada’s Excel-based Air-source Heat Pump Sizing and Select Tool and accompanying guide, offering a simplified system that improves user experience and allows users to create and keep track of multiple projects.
The ASHP Sizing and Selection App helps designers and contractors quickly define ASHP systems that will meet the needs of their clients. Users begin by creating a project and identifying important factors to be considered for their specific scenario and can then use the app to determine potential heat pump solutions. Collaborators can be added to the project allowing designers, contractors, builders, and other parties to exchange comments on proposed solutions within the app and work together to select the most appropriate ASHP system.
