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.

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.

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

The first scheme of renewable energy grants for Irish homeowners, the Greener Homes Scheme, was launched on Monday 27th March 2006 and will make grant funding available to homeowners looking to install renewable energy heating technology

Since the announcement last September by the Minister for the Environment of substantial improvements to be made under Part L of the Building Regulations, speculation has been rife in the construction industry about what the details of the updated regulations would entail. Jeff Colley examines some of the key parts of a regulatory improvement that will help the Irish construction industry to modernise and meet the demands of a rapidly changing world.

The building is the first all timber office complex in Ireland. It covers almost 2,300m2 of floor space and provides accommodation for almost 100 staff working in a wide range of forestry related disciplines.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

In light of the current economic conditions, an increasing number of Irish people are turning away from buying new homes, instead deciding to make the most of what they’ve got by extending and refurbishing. Lenny Antonelli visited one such house nearing completion in Glasnevin that uses a combination of materials and techniques to aim for highly sustainable results.

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.

Architect Paul Leech explains why the new Navan Credit Union is arguably Ireland’s most innovative sustainable building to date, and outlines his hopes that the experience gained from this project can help the construction industry to realise sustainable building in Ireland.
