If one was to draw a conclusion on how seriously sustainability is being taken at government level using the number of occurrences of the word "sustainable" in policy documents, housing guidelines and speeches from Ministers, it would come across that Ireland's on a sound sustainable footing.

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

As we all know, Ireland is currently paying the price for the inability of its political and corporate leaders to take seriously the warning signs of an economy where property investment and borrowing generally got out of control. Looking at policy and commercial investment plans for energy supply and distribution, Richard Douthwaite asks, are the decision makers showing an alarmingly similar attitude to evident gas supply threats?

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.

Randy Ralston and Mel Cronin aimed for the passive house standard with their upgrade, and though they didn’t quite get there they ended up with a house that produces more energy than it consumes, making it one of the country’s flagship green renovation projects.
