Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

Staggeringly airtight ecological home in Athenry set to meet the Passive House Institute standard

As fossil fuel prices rise, the need for energy efficiency in achieving both is increasingly leading Irish people to an approach which combines both ventilation and heating,

With the building of a new house in Greystones, County Wicklow, Ireland has become only the third country to feature the work of Frank Lloyd Wright. Jason Walsh visited the site to see if Wright's designs might just represent the kind of thinking required in today's energy-conscious buildings.

The environmental impact of the built environment extends far beyond energy consumption and carbon emissions throughout a building’s intended lifespan. Architect and sustainable design consultant Sinéad Cullen of DW EcoCo & BE Architecture explains why there’s a need to design buildings that can be deconstructed rather than destroyed once they reach their end of life, and looks at the obstacles to be overcome to make this happen.

Much of the debate on reducing international carbon emissions has focused on the extra cost of making the necessary cuts to slow the onset of climate change.

Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.
