Kevin O’Flaherty’s development overlooking Galway Bay combines impressive energy saving techniques with the sorts of features that buyers of high-spec homes have grown to expect, as John Hearne discovers.

Construct Ireland and Century Homes present the need for Energy Labels before the Joint Oireachtas Committee

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.

U-value alone is a blunt instrument for gauging the thermal performance of a building. Ground-breaking eco architects Joseph Little and Benat Arregi of Building Life Consultancy explain why our increasingly ambitious insulation efforts must involve a rigorous attention to thermal bridging if we’re serious about creating low energy, healthy buildings.

Construct Ireland spoke to the six newest approved ÉASCA members, companies involved in everything from eco-friendly timber frame
homes and natural insulation, to energy rating, eco friendly cement and a variety of other sustainable building products.

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.

Box-like, small windows, primary colour renders - there is a common misconception that building to the passive house standard involves sacrificing design freedom for the sake of thermal performance. Not so, argues passive house guru Tomás O’Leary of MosArt and the Irish Passive House Academy, as his selection of architecturally diverse buildings reveals.

The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains

If achieving eco buildings is challenging for new build, it is doubly so for renovation projects. Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.

As the January 2006 deadline for implementation of the EU Directive on the Energy Performance of Buildings draws ever nearer, the Irish Government has spelt out its plans to delay the across the board introduction of building energy ratings until 2009. But how does this compare to other EU Member States?
