This document describes a method for assessing the energy performance of an occupied building based on metered energy use, and includes a software implementation of the method. Recent UK and European initiatives mean that the benefits of performance assessment are being backed by legislation. TM22 and its software provides support for these assessment needs. While primarily directed at assessing energy performance, the procedure has a wide range of uses for building managers, design professionals, and energy management specialists contributing to the 'virtuous circle' of good building management and satisfied occupants.

This publication is supported by a number of supplementary files that are freely available here. For hard copy purchasers, these were previously supplied on CD but should now be downloded using this link.
