The Energy Performance of Buildings Directive sets out the general framework for the calculation of building energy performance and the assessment tools that have been developed for the UK (the Standard Assessment Procedure (SAP) for dwellings and the Simplified Building Energy Method (SBEM) for non-dwellings) comply fully with those requirements. If a future revision of the directive amends this framework then we would aim to comply with those requirements.
My Department has consulted extensively with industry. In addition, I have replied to 13 letters which I received on this issue. These were from individual businesses involved in the heating industry sent via their respective Members of Parliament. I have also responded to 45 parliamentary questions on this topic since January 2008.
