Kensa Heat Pumps is hoping the revised Building Regulations standards for new-build homes in England, which are due to be brought in from June 2022, means flexibility will become a key factor when assessing renewable energy solutions rather than efficiency alone.
Kensa also hopes Standard Assessment Procedure (SAP) ratings will reflect this following the Part L and F revisions to the regulations.
Kenso CEO Simon Lomax said: “It is vital that SAPs can accurately assess the performance of emerging system architectures and technologies. Many ground arrays can use waste heat to bolster the source temperature to improve efficiency and reduce running costs and carbon emissions. This advantage must be reflected in SAPs.
“Equally, the most appealing solutions, for house builders and house owners, will be heat pumps integrated with heat batteries to maximise the ability of the heat pump to operate when electricity is both low cost and low carbon. Pure efficiency is no longer the key metric: flexibility is more important to deliver the best outcomes for all stakeholders.”
