Home Quality Mark cost output
The Home Quality Mark One, Technical Manual SD239, England, Scotland & Wales, published by BRE in 2018 defines cost output as a metric that is:
|
…unique to the HQM and is calculated by the HQM energy engine using modelled outputs from approved building energy calculation software, against which cost credits are awarded. It is an output based on the energy cost factor metric taken from the SAP assessment. When calculating the cost output, a home’s actual performance is compared against the relevant national Building Regulations compliance standard (i.e. a baseline), and the comparison is expressed as a percentage improvement. The percentage improvement is then compared against a best practice performance level for modelled stock of house types, and then ‘translated’ into a cost output. |
A description of how to obtain a home’s cost output is summarised in the Methodology section on P112 of the Technical Manual and more detail about how the cost output is defined and calculated is provided in Guidance note 28 available at: https://kb.breeam.com/knowledgebase/gn28-home-quality-mark-hqm-energy-and-cost-methodology-guidance-note-draft/
