Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

Nothing focuses the mind like a target. The growing impact of Building Energy Ratings (BER) is increasingly encouraging Irish people to aim for the highest energy rating they can. Patrick and Niamh Daly’s house in Mullingar takes this trend to the next level, using a myriad of sustainable green materials and technologies to become a net energy producer and go beyond the limit of the BER scale. John Hearne visited the nearly completed house to find out more.

The rendering industry in Ireland is in a process of change and thus has been the centre of much heated debate between renderers, the meat industry, Irish livestock farmers and the Department of Agriculture and Food.

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.

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

In spite of the obvious emergence of technologies and design approaches to reduce the impact of new build, environmental standards remained poor throughout the duration of the housing boom. Now, a unique combination of political will, smart incentives, and a new market of informed and empowered buyers may be about to change that, writes Lenny Antonelli

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli
