If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.

As of 2006 there is more and more talk in Ireland about the house of tomorrow and some very progressive houses have been built that go far beyond the basic legislative requirements for modern housing. Among them is Baile Glas, a development of twelve social and affordable housing units in Lombardstown, County Cork, initiated by the Blackwater Resource Development Agency and Cork County Council. Construct Ireland’s Jason Walsh finds out more.

The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.

Every eurozone government has debt problems and is cutting its spending, Richard Douthwaite says. Defaults and a prolonged depression are inevitable unless countries inject money into their economies in an unconventional way. A prosperous low-carbon economy would be the result

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

Jason Walsh spoke to David Smith of O'Mahony Pike Architects about the practice's uniquely-designed show apartments for this year's Myhome.ie Spring House and Garden exhibition.

Richard Douthwaite reveals that oil and gas peak are barely mentioned in the Government's recent energy Green Paper.

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. 

Energy Minister Eamon Ryan recently announced a e9 million fund to be administered by SEI for sustainable housing including, crucially, micro-generation of renewable electricity. Jason Walsh talked to SEI and industry figures to examine the scheme’s future.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.
