BS 40101, Building performance evaluation of occupied and operational buildings (using data gathered from tests, measurements, observations and user experience) – Specification, was launched early in 2022. The standard was intended to be applicable to recently completed and existing buildings of all types and scales to provide a consistent basis for establishing and recording the actual in-use performance of buildings. It was intended that results obtained through the application of the standard could satisfy diverse needs ranging from verification of designed performance, providing information on which to improve design and delivery of future buildings, to understanding performance prior to (and after) improvement works and investigating reasons for excessive energy demand or occupant concerns.
With BS 40101 having been in circulation for over two years, it is time to take stock to understand where and how the standard is being used, the purposes it is being used for and why it is not being used where it could be beneficial. Following this survey BSI is expected to set in motion a refresh of the standard to enable it to be used more widely. The anonymized results of the survey will also be shared with the wider BPE community including those involved in training/CPD, development of guidance material and case studies to improve the adoption building performance evaluation and hence improve the performance of buildings in use.
Whether you are an existing user of BS 40101, someone who carries out any form of building performance evaluation, a client, designer, constructor, finance provider or are involved in policy and regulation in the buildings and building improvement sectors, please take a few minutes to respond to the survey here.
