Wimbish Passivhaus asks What Performance Gap?!
Wimbish Passivhaus was completed back in 2011, and was a first for all involved in creating the scheme. The development was the subject of a Building Performance Evaluation study supported by the Technology Strategy Board (TSB). All 14 units were equipped with sensors to log energy consumption, thermal comfort, and air quality.
Measured performance data and occpancy feedback from this study was presented at the 2014 UK Passivhaus Conference. The data proves that the housing is performing as predicted. In John Lever, Hastoe Housing & Martin Ingham, Linktreat presentation they mentioned that a brief Case Study, and a longer Executive Summary, both derived from the detailed TSB study, were to be made available. These can now be downloded at Wimbish Passivhaus.
The study has confirmed that building to Passivhaus quality is the way to deliver excellent low energy homes at an affordable cost, delighting both residents and the housing association. This is remarkable because the development was a first for all involved and the experience will bring future improvements. Martin Ingham, Linktreat Ltd, TSB - Wimbish Passivhaus Delivers Case Study
The case study not only outlines performance data, but also includes analysis of the effects of occupants behaviour and tips for future Passivhaus developments.
