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.

Ireland — along with much of the western world — relies on the International Energy Agency‘s oil production forecasts. But are they reliable, asks Lenny Antonelli?

It is not alone as an artist and historical author of distinction that Peter Pearson is noted.  His role as a conservationist in the last three decades has had a tangible effect in protecting Ireland’s built heritage, and raising consciousness of the value and importance of conservation work

Public private partnership schemes have come to dominate many aspects of Irish infrastructural development, from toll roads to urban regeneration schemes. Jason Walsh asks if they amount to privatisation by stealth and whether they come at too high a social and environmental cost.

In light of Ireland’s poor performance in the recent European Environment Agency Report on drinking water quality, the issue of Ireland’s wastewater treatment from one off houses is poised to stay in the spotlight. Construct Ireland’s Pat Kennedy, environmental engineer, investigates.

Economic analysts are starting to warn of the threat rising oil prices pose to Ireland’s recovery prospects. Richard Douthwaite argues that energy efficiency and renewables investments must be central to government plans, and explains how more than 100% of the cost of energy investments may come back to the exchequer.

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.

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.

With 36 years experience in ecological architecture, Paul Leech of Gaia Ecotecture possesses a formidable knowledge of international green design. Fresh from picking up the best ecological building 2010 Lama award for the pioneering Navan Credit Union  – and a favourable review in Prof George Baird’s Sustainable Buildings in Practice: What the Users Think - a global survey of green buildings - Leech describes a handful of inspirational green exemplar projects from around the world.

The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.
