The new technology provides'actual' thermal fabric performance data Knauf Insulation EXCLUSIVE: System that uses machine learning to measure the'actual' fabric thermal performance of a home within three months could provide evidence base for national retrofit programme Knauf Insulation has developed a technology that uses machine learning systems to accurately measure the'actual' energy performance of individual homes, an innovation that could drastically enhance the accuracy of energy performance certificates (EPC), BusinessGreen can reveal. The new technology, which can generate an assessment of fabric performance of a home within three months, could provide the evidence base for an energy efficiency retrofit programme for the nation's homes, the company said. The "discreet, scalable and cost-efficient" measurement tool ensures the building fabric component of a building's EPC rating can be backed by real evidence, rather than "notional Standard Assessment Procedure calculations", according to Knauf Insulation. The company stressed the tool marked a major departure from other available techniques to measure'actual' fabric thermal performance, which it said were "intrusive and expensive". Steven Heath, technical and strategy director of Knauf Insulation, celebrated the launch of the product, noting that the UK's 2050 net zero emissions ambition depended on the country's housing …
