A cursory browse through Dublin Civic Trusts website and one is all too quickly reminded of the constant threat to our Architectural heritage

Foxrock passive development built with externally insulated poroton & aircrete blocks along with timber frame

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.

Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Architect Eva Murphyova creates a modern and sustainable take on the traditional farm settlement with the addition of a new envelope, timber frame extension and sustainable heat sources

A sustainable building must address more than energy, carbon or materials, argues Irish born architect Stephen Roe of up-and-coming London architects Roewu – it must respond to its environment. Not only does Roe’s design for the All Weather House achieve that, it boasts green materials, renewable heating and generous insulation too.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli
