Publisher's Synopsis
Built environment clients are increasingly interested in the operational energy performance of the buildings that they invest in, procure, or occupy. This can lead to targets being set in the project brief to achieve energy performance in line with the design estimates. As a result, building services engineers and energy consultants are being asked to provide estimates of the likely operational energy performance of buildings at the design stage, and accordingly to inform the design proposals. This document aims to help building services engineers and energy modellers to respond to this request in a robust way.
