The HQM energy engine is built into the full HQM assessment tool within BREEAM projects. To use the engine to calculate the HEPR for a home, you need to register a project on BREEEAM projects and upload the relevant files listed in the ‘Methodology’ section of the ‘Energy and Cost’ assessment issue. The engine is not currently available via the pre-assessment tool.
There is also an excel tool (HQM-2015-Beta-Energy-forecast-and-cost-IE-Pr-70-0201-.xltx) that is used in combination with the HQM energy engine when credits are sought via the comprehensive route in the ‘Energy and Cost’ assessment issue. This tool is available in BREEAM projects, under ‘Home Quality Mark 2015 Beta Assessment Tools’.
