Passive Housing

Built in 2004, Tomás O’Leary's house in Wicklow was the first in the country to be certified by the Passive House Institute — but how would it fare when subjected to a BER assessment six years later?

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.
