Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

Built on stilts, entirely encased in recycled newspaper insulation on all sides, and designed to be easily taken apart so that its constituent elements can be reused once it reaches its end of life, Portlaoise Locomotive Drivers Building could hardly be more green. But it is – it’s a certified passive house. Iarnród Éireann senior architect David Hughes explains how such a sustainable exemplar came to be.

Can a supermarket be green? Tesco's new store in Tramore, County Waterford suggests that, at least in terms of the building it’s housed in, the sky’s the limit. Jason Walsh visited a building which meets passive house standards and demonstrates impressive attention to sustainability throughout its design.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

Randy Ralston and Mel Cronin aimed for the passive house standard with their upgrade, and though they didn’t quite get there they ended up with a house that produces more energy than it consumes, making it one of the country’s flagship green renovation projects.

With the building of a new house in Greystones, County Wicklow, Ireland has become only the third country to feature the work of Frank Lloyd Wright. Jason Walsh visited the site to see if Wright's designs might just represent the kind of thinking required in today's energy-conscious buildings.

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.
