Lessons from AHMM’s Stirling Prize-winning Burntwood School building performance study

Episode 27. We continue our focus on building performance; AHMM sustainability lead Craig Robertson shares important lessons from a building performance study of 2015 Stirling Prize-winning Burntwood School in southwest London. It is still much too rare for architects – and clients – to transparently share post-occupancy data, especially when it flags up a significant performance gap, so kudos to AHMM for sharing this study with us. In the case of Burntwood School, heating loads were nine times the design prediction, while electricity loads were four times as much. Shocking as this may sound, it is not unusual. Craig explains why and what we need to do about it. A key premise of the study was to investigate the relationship between energy performance and indoor environmental quality. These must be looked at in tandem. Our conversation with Craig reveals, in practice, the many building performance issues we discussed in our last episode with Judit Kimpian.
