Home Quality Mark high temperature reporting tool
The Home Quality Mark (HQM) high temperature reporting tool is a reporting tool that feeds into a calculation methodology to identify a home’s threshold temperature. This has been developed by BRE solely for use within the foundation route of the Temperature issue of the HQM assessment.
The intention of this tool and accompanying calculation methodology is to support the offering of capped credits to homes whose circumstances make them less likely to be at risk of overheating during summer months, where full dynamic thermal analysis is not completed.
It assesses and scores the building on key factors that affect overheating risk on a whole house basis, and should not be treated as a detailed tool to identify the presence or absence of localised overheating.
The identified threshold temperature for the home uses data from Standard Assessment Procedure (SAP) outputs and additional bolt-on inputs relating to the following topics:
- Surroundings.
- Provision of mechanical ventilation.
- Capacity for natural ventilation.
- Solar gains.
- Heat gains from communal heating.
- User factors.
The calculation methodology to determine the threshold temperature is described in the HQM Temperature supporting document.
Please note: this tool and accompanying calculation methodology will produce an estimated output founded on basic information inputs. To establish the overheating risk of a home, BRE Global would always recommend completing full dynamic thermal modelling in accordance with best practice.
