Duncan Stewart demands an energy revolution

Cork city split level timber frame house with passive solar design, rainwater harvesting, renewables & green material

Number Two Grand Canal Square office, completed in September 2009 and substantially occupied by law firm Byrne Wallace in August this year, set a landmark in commercial office development by combining world-class design with sustainability - reconciling the architecture of Daniel Libeskind with achieving both a Breeam Excellent rating and an A3 BER certificate. Paul Dunne, sustainability and M&E director for Arup, outlines some of the project’s history and its achievements

Hugh Dorrian, member of the Main Committee of the recently launched Building Limes Forum Ireland reveals lime is regaining ground as a key material not only in conservation projects, but in new build.

Fears are growing amongst energy rating trainers that Ireland is running out of time to ensure building energy ratings are in place for existing homes at point of sale or rental from January. Jeff Colley spoke to SEI and to leading figures involved in energy rating training to find out more and shed some light on how homes will be assessed.

A new public park on the northside of Dublin combines wind power and sustainable water management with environmentally sound materials and strategies to boost biodiversity, making it a standard-bearer in urban design. Lenny Antonelli visited the site

There are surprisingly few truly iconic buildings, structures that dominate their environs, not to mention the country's intellectual landscape. Halla Chontae Chorcai, Cork County Hall, is one such building. Construct Ireland's Jason Walsh visited to find out about the building's environmental credentials.

“The thing to bear in mind is that even though it got knocked down, every single window sill went into another house, all the flooring and slates went into another house”, says Stephen Porter of Stonebrokers on the recent demolition of Lough na Vale in Sandymount.

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.

The emergence of climate change as a serious concern has helped create a burgeoning market for a vast range of eco technologies. All too often, however, the basic principles of sustainable design are ignored or misunderstood. Chris Croly of mechanical and electrical engineers Building Design Partnership describes the detail of a building which reveals a no-nonsense attention to sustainability.
