Hadlow College
Download
as PDF The Rural Regeneration Centre (RRC), part of Hadlow College, was designed and built by UK company Eurobuild in 2009-2010. It was the first certified PassivHaus building in the Education sector in the UK and has now been occupied for about 2 years. Built for less than the standard cost, it costs the client less than 14 per month on average for heat energy and performs to the PassivHaus standard (as designed) when the building is operated by the users with commissioned settings. Artificial lighting is barely used due to the effective daylighting design strategy. Constructed in a factory off-site, the building was erected on-site in less than three days, and airtight (0.34h-1) to PassivHaus standards in under 10 days, saving a six week construction period over a standard build and further reducing waste and emissions. Overall, the clients are delighted with the building. It is popular with staff and students, as well as with visitors as a conference venue.
