Passive Housing

Staggeringly airtight ecological home in Athenry set to meet the Passive House Institute standard

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

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.

When residents of Hollywood solemnly and publicly state the need to combat climate change, it is easy to reject as self-righteous, opportunistic bleating. When it’s a resident of Hollywood, County Wicklow, and the environmental statement is in the form of a poroton-block house infused with sustainable features, it provokes an altogether different response, as Lenny Antonelli reveals.

On Tuesday the 15th of March a passive house, a house that does not need to be heated, was built a few miles outside of Galway. The brain child of Lars Pettersson of Galway based Scandinavian Homes Ltd, it is believed to be the world’s first standardized and factory made passive house.

The Passive House standard, an internationally renowned approach to building that negates the need for conventional heating, has attracted considerable interest in Ireland recently as energy prices continue to rise. Vivienne Brophy, Dr Irena Kondratenko, Patxi Hernandez and Kevin Burke of UCD’s Energy Research Group look at the effect this approach could have on cutting Ireland’s energy consumption and CO2 emissions.

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

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.

Turning a ruined farm house into a usable dwelling has been a dream for decades, but can an age-old structure really be brought-up to the cutting edge of energy efficiency? Architect Frank Cooney has found a way with a ruin in Cavan currently undergoing renovation. Jason Walsh visited the site to find out more.

Can a supermarket be green? Tesco's new store in Tramore, County Waterford suggests that, at least in terms of the building it’s housed in, the sky’s the limit. Jason Walsh visited a building which meets passive house standards and demonstrates impressive attention to sustainability throughout its design.
