Assessing the Impact on Agriculture of Predicted Changes in Irish Climate by Dr Nicholas Holden

Cork city split level timber frame house with passive solar design, rainwater harvesting, renewables & green material

In the first installment of a new feature on international green buildings, Lenny Antonelli takes a look at five innovative, sustainable and striking buildings from around the world.

An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

Energy Minister Eamon Ryan recently announced a e9 million fund to be administered by SEI for sustainable housing including, crucially, micro-generation of renewable electricity. Jason Walsh talked to SEI and industry figures to examine the scheme’s future.

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.

Many of the opportunities that trees offer for sustainable building are harnessed by a housing development in Ballymahon, Co. Longford which combines timber frame construction with recycled newspaper insulation and wood pellet heating. Adding in solar panels and attention to detail for airtightness, these low energy, low carbon homes reveal a developer who sees a bright future in going green. John Hearne visited the site to find out more.

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

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.
