The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.

It’s not surprising that a 1970s bungalow on an exposed north-facing site might be draughty and burdened with high energy bills - but external insulation, a new heating system and a brand new roof can make all the difference. Lenny Antonelli reports.

As the new-build sector grinds to a halt a window of opportunity has opened for builders, architects and other construction service providers – refurbishing Ireland’s existing housing stock. Jason Walsh visited an end-terrace house in inner city Dublin to see just how significant the improvements can be.

A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing

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.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

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.

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

At the start of July a key event in the Irish construction industry passed almost entirely unnoticed, with the requirement that the brand new Dwelling Energy Assessment Procedure (DEAP) calculation software be used for all planning applications for new homes with immediate effect. The new tool will be used to calculate Building Energy Ratings (BER) under the requirements of the Energy Performance of Buildings Directive (EPBD). Patrick Daly, lecturer in Environmental Design in the School of Architecture at DIT Bolton St. reveals his view on DEAP and its impact on the industry.
