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

The government recently announced a fund of e100 million for energy upgrading Irish houses in 2009, to be divided equally between low income and middle income earners. Focusing on the latter, Jason Walsh looks at the details of the Home Energy Saving scheme and speaks to key figures in the industry to get their views on the ingredients needed to make the scheme a success

Semi-state business Bord Gáis have placed green innovation at the centre of their business strategy. As CEO John Mullins reveals, pay as you save and renewable energy will shape the company’s future.

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.

In April this year the first NSAI Agrément certificate was issued for the application of external insulation to existing dwellings. Joseph Little of leading green architects Joseph Little Architects used analysis from his practice’s Building Life Consultancy service to assess the certificate, and encountered issues which raised questions over whether it should have been issued in its current form.

In September, Sustainable Energy Ireland launched a major energy efficient housing development in Tuam, Co Galway. Houses in the development are over 70% more energy efficient than houses built to standard Building Regulations requirements. Construct Ireland’s John Hearne describes.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.
