Newly elected Green Party Ministers John Gormley & Eamon Ryan talk to Construct Ireland about their vision for a sustainable future.

Patrick Daly  highlights that the energy refurbishment of our existing housing stock must become a priority. Daly has undertaken a retrospective DEAP case study assessment of an example house and its BER ratings, with staggering results.

It’s not often you find an industrial facility that combines low carbon construction with emphasis on natural materials, occupant health and energy efficiency, but Rehan Electronics’ new Wicklow factory is no ordinary building. Lenny Antonelli paid a visit to what must be Ireland’s greenest factory.

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

With banks in America and the UK encountering major difficulties as previously booming economies head towards recession, a similar and perhaps even worse fate may be awaiting Irish banks. Worryingly, the situation is shaping up to be so bad, that the very future of the banks may be under threat, as Richard Douthwaite explains.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

Geothermal heating is being specified by everyone from self-builders to developers to local authorities in increasing frequency across Ireland. As a relatively new technology in Ireland, it is crucial that anyone considering a geothermal system knows what they are getting into, to ensure an efficient, reliable heating source.

With over 20 years experience in this field in Ireland, Dr Paul Sikora, Vice Chairman of the Geothermal Association of Ireland explains what issues to be aware of when considering geothermal, from site suitability, to what to look for from suppliers and installers.

Homeowners thinking of applying for Home Energy Saving scheme grants should pay close attention to a renovation project in Stillorgan, south Dublin. The refurbishment boasts every upgrade measure grant-aided under the scheme, including three types of wall insulation, a high efficiency boiler and sophisticated heating controls.
