Construct Ireland and Century Homes present the need for Energy Labels before the Joint Oireachtas Committee

Ireland ’s reliance on fossil fuel sources for electricity generation places the whole country on unstable ground as these limited resources dwindle

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.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

A new development in the historic town of Thomastown, County Kilkenny brings the cutting edge of green innovation into a setting known for its medieval heritage. John Hearne visited the site, where a commitment to the environment is evident in sustainable design combined with everything from airtight detailing to technologies such as factory insulated timber frame, low energy windows, solar thermal, photovoltaic and heat recovery ventilation

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.

Jason Walsh visited the recently refurbished offices of Wicklow County Council to see an approach that achieves energy conservation, carbon reduction and dramatically increased occupant comfort by lowering electricity and heat demand and avoiding unwanted overheating
