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?

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.

During his tenure as energy minister Eamon Ryan instigated plans to energy upgrade Ireland’s draughty, damp housing stock. Ryan and his wife, writer Victoria White, show Construct Ireland how their own home has been given the green treatment, and architect Mike Haslam of Solearth describes the project.

With money leaving local economies across Ireland to service debt and significant drops in local authority revenues, towns such as Dundalk, Ennis and Kilkenny are investigating the possibility of bringing in electronic currencies to keep money circulating locally, as Richard Douthwaite reveals.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

In the third installment of a new feature on international green buildings, Lenny Antonelli takes a look at more innovative, sustainable and striking buildings from around the world.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

Fingal County Council have clearly shown a laudable commitment to innovation by introducing a mandatory planning requirement for seven areas that all new developments reduce energy use and C02 emissions relating to space & water heating to 60% below Building Regulations requirements, with 30% of space & water heating coming from renewable energy sources
