Richard Douthwaite looks at the viability of heat pumps, and the factors that could determine their future role in a changing energy landscape.

For the first time in several years, 2007 will see a budget deficit in Ireland so the question must be asked: where does this leave state aid for sustainable building? Construct Ireland’s Jeff Colley and Jason Walsh propose a new approach to improving the energy efficiency of existing homes that might even fix a few of the difficulties seen in the last eighteen months

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.

During his tenure as energy minister Eamon Ryan instigated plans to energy upgrade Ireland’s draughty, damp housing stock. Ryan and his wife, writer Victoria White, show Construct Ireland how their own home has been given the green treatment, and architect Mike Haslam of Solearth describes the project.

Two years ago Construct Ireland ran a case study on Mater Orchard, a Mercy Sisters convent building that successfully balanced cutting edge technologies with pragmatic green design. Such was the success of that building, its architects were commissioned by Mercy Sisters in Limerick to repeat the feat. John Hearne visited the freshly completed building to find out how they fared

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

Recently sold by private tender for over e1.3 million, the ECO House in Shankill, Co. Dublin exceeded auctioneers expectations, an indicative example of the shift from public curiosity to eagerness to invest in contemporary sustainable building.

The Orchard, a new building on the campus of Stranmillis College, a teacher training college in Belfast, has become the first winner of a sustainable planning award organised by the Royal Town Planning Institute alongside a host of other awards. Jason Walsh visited the new building to find out about its green credentials.

After a long struggle to build their home, Karen and Steve Ward finally got their wish — an energy efficient, timber frame house that boasts a palette of healthy and ecological materials and a fully renewable heating system.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists
