摘要

The UK's commitment to reduce CO_2 emissions by 80 per cent by 2050 presents the construction industry with an extremely difficult challenge. To produce the highly energy-efficient new buildings and adequately retrofit the 20 million existing ones we must start to use all the tools at our disposal. Worryingly, it is now apparent that a significant gap between the as-designed thermal performance of buildings and the actual performance already exists. This paper puts forward the case that a significant contributor to that gap is the regulatory regime that has been put in place, which allows the U-values of all the building components and structures to be calculated - never verified by measurement. A list of the main measurement and calculation standards that are available is then given with a brief description of their possible place in a rigorous system for ensuring that building designs are based on accurate, validated thermal performance values for the structures from which the energy performance is calculated.
