Passive Housing

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

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?

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

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.

Randy Ralston and Mel Cronin aimed for the passive house standard with their upgrade, and though they didn’t quite get there they ended up with a house that produces more energy than it consumes, making it one of the country’s flagship green renovation projects.

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.

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.
