There has been a growing awareness for some time that many ‘low energy buildings’ use more energy than the designers thought they would. As energy costs have risen, this awareness has started to spread to building owners, who hear much about low energy buildings and subscribe to programmes that rate the design of the building, only to find that their ‘low energy design’ turns out to have a typical energy bill. The performance of low energy designs is often little better than that of an older building they have replaced, or supplemented.
There is a mismatch between the expectations around the performance of new buildings and the reality of the utility bills. This difference between expected and realised energy performance has come to be known as the ‘performance gap’. CIBSE TM:54
Join the IES Team in London on Wednesday 24th September (4pm – 6pm), for the return of the next instalment of our popular interactive Faculty series, where we explore the Performance Gap phenomenon in detail. We’ll discuss what we can do to improve the accuracy of our design modelling, with an insight into the newly released CIBSE TM:54. Following on we’ll discuss the advantages of Soft Landings and what recent advances in Building Simulation can allow you to use real building data to improve the Design Process of new buildings.
Can’t make the seminar in person? Don’t worry, we’ll be providing live updates throughout the event on our live twitter feed, using the #PerformanceGap hashtag. Not only can you follow our World Green Building Week event live but you can also play your part in the discussion taking place, by filling out this quick survey below and by putting your questions and issues to our team using the #PerformanceGap hashtag or the comments section of this blog post.
The Faculty seminars are a place for interaction among the industry and the more feedback that is provided, the better we can start to address the issues we are all facing. It’s time for us to close the #PerformanceGap.
