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

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.

Construct Ireland spoke to the six newest approved ÉASCA members, companies involved in everything from eco-friendly timber frame
homes and natural insulation, to energy rating, eco friendly cement and a variety of other sustainable building products.

The environmental impact of the built environment extends far beyond energy consumption and carbon emissions throughout a building’s intended lifespan. Architect and sustainable design consultant Sinéad Cullen of DW EcoCo & BE Architecture explains why there’s a need to design buildings that can be deconstructed rather than destroyed once they reach their end of life, and looks at the obstacles to be overcome to make this happen.

Kirk Shanks, Senior Researcher at the Sustainability Research Development Group, the Focas Institute, DIT describes the development of this new sustainable generation.

 
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.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

Ireland ’s reliance on fossil fuel sources for electricity generation places the whole country on unstable ground as these limited resources dwindle
