HEM is the new government methodology for assessing energy performance of UK homes
Sustenic, in partnership with Quidos, has been awarded a high-profile contract by the Department for Energy Security and Net Zero (DESNZ) to develop and maintain the core software engine for the Home Energy Model (HEM), the new government calculation methodology for assessing the energy performance of homes in the UK.
HEM will support energy efficiency improvements in a wide range of new and existing housing types in the UK, aligning with the upcoming Future Homes Standard and reformed Energy Performance Certificates (EPCs). By offering a more accurate assessment of building energy performance, it will help to reduce the nation’s carbon emissions in the journey towards net zero.
Sustenic will draw on its many years of experience developing and implementing energy calculation methodologies to lead the development of the HEM engine, and maintain the underlying Python codebase. Quidos will play an important role in feature development and maintenance, leveraging its experience in developing energy assessment software and its 20 years expertise in assessing the energy efficiency of dwellings.
Work will begin immediately on a consultation version of the core engine.
Jose Ortiz, Director at Sustenic, said: “This contract award marks an important milestone in the evolution of building energy modelling in the UK. Our team brings unparalleled expertise in energy modelling methodologies and software development, having previously played central roles in developing SAP, SBEM, and the initial phases of HEM. We’re looking forward to working closely with Quidos, DESNZ and the MHCLG to deliver this critical project successfully and assist in the UK’s net zero ambitions.”
Chris Barrington, CTO at Quidos, said: “Improving the energy performance of the UK’s homes is crucial to achieving carbon emission reduction objectives. Our established reputation in energy efficiency software and assessment will be invaluable in the development of the HEM’s core software engine, together with Sustenic’s deep methodological expertise. Together we will ensure that HEM is a reliable, user-friendly tool that supports industry professionals in delivering energy-efficient dwellings.”
