When Construct Ireland asked Vivienne Brophy of the UCD Energy Research Group to select projects for this feature she suggested that the second year UCD Architecture students make the selection, using UCD’s sustainable building rating system tool to verify their choice

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

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.

At Tom Heneghan’s new development in Dromard, Belmullet, Co. Mayo, it’s a case of sixteen units down, eleven to go as Construct Ireland goes to press. Exceeding the thermal performance requirements of the Building Regulations by some 60%, these houses incorporate a range of innovative and affordable sustainable building technologies which together deliver high comfort, low energy living, as John Hearne reveals.

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.

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 aftermath of our recent awareness raising, Construct Ireland began to research what measures the Irish government was taking to prepare for the Energy directive, and how this compared with views from other EU member states, an investigation that is revealing startling results.

Is it possible to ditch fossil fuels and run a 1970s Irish bungalow on solar energy? Norman McMillan’s renovated A1-rated bungalow in Carlow proves it is. 

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.

Since the announcement last September by the Minister for the Environment of substantial improvements to be made under Part L of the Building Regulations, speculation has been rife in the construction industry about what the details of the updated regulations would entail. Jeff Colley examines some of the key parts of a regulatory improvement that will help the Irish construction industry to modernise and meet the demands of a rapidly changing world.
