Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

Stricter air-tightness standards might be helping to reduce energy use in new build, but is it leading to higher indoor concentrations of chemical and biological toxins? Lenny Antonelli investigates an emerging approach to building that is combining attention to environmental impact with consideration for the potential health effects of modern building materials and practices.

A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

 

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.

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

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable

Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.

Conventional wisdom dictates that higher construction costs — for instance to reduce energy consumption and carbon emissions — would either squeeze developers’ profit margins or increase house prices. Tom Dunne, Head of DIT’s School of Real Estate and Construction Economics, reveals how misguided this view could be...
