Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.

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.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.

It has long been anticipated that the cost of sustainable building will come down as it enters the mass market, benefiting from economies of scale and greater industry confidence in low impact techniques and technologies as they become more familiar. Jay Stuart, managing director of integrated sustainable design consultants Delap and Waller EcoCo reveals a Kildare housing project which is likely to rapidly accelerate this process, and convince even the most conservative elements of the industry that low energy, low carbon building can be achieved at little or no additional cost

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.

When designing and building high density apartment and housing developments, the attention, so often lacking, to acoustic performance, can have a critical impact on the quality of life of the buildings’ inhabitants, as leading acoustic consultant Jim Dunne, Managing Director of Integrated Acoustic Solutions explains

The German-Irish Chamber of Industry and Commerce (GICIC) has just completed a study titled “The Potential of Renewable Energy in Ireland”.
Based on the study’s findings, Bernd Reinhard, Deputy Executive Director of the GICIC outlines the potential that fast emerging renewable technologies possess to revolutionise Ireland’s energy supply, from wind power’s capacity on a national level, to the benefits the likes of solar and geothermal can offer proactive homeowners

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.
