Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack

Adding to the list of developers aiming to deliver energy efficient housing, Cronan Nagle Construction are currently on site with 188 highly insulated, airtight homes in Ennis, co. Clare. The development, which also incorporates heat recovery ventilation and condensing gas boilers is surpassing the thermal requirements of Building Regulations by up to 45%, as John Hearne discovers.

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

The desire for better insulated, more environmentally friendly homes is driving ever more Irish self-builders to investigate alternatives to traditional block building. Jason Walsh visited a contemporary style factory-built timber frame house built in County Waterford in 2005.

For the first time in several years, 2007 will see a budget deficit in Ireland so the question must be asked: where does this leave state aid for sustainable building? Construct Ireland’s Jeff Colley and Jason Walsh propose a new approach to improving the energy efficiency of existing homes that might even fix a few of the difficulties seen in the last eighteen months
