With 36 years experience in ecological architecture, Paul Leech of Gaia Ecotecture possesses a formidable knowledge of international green design. Fresh from picking up the best ecological building 2010 Lama award for the pioneering Navan Credit Union  – and a favourable review in Prof George Baird’s Sustainable Buildings in Practice: What the Users Think - a global survey of green buildings - Leech describes a handful of inspirational green exemplar projects from around the world.

The Orchard, a new building on the campus of Stranmillis College, a teacher training college in Belfast, has become the first winner of a sustainable planning award organised by the Royal Town Planning Institute alongside a host of other awards. Jason Walsh visited the new building to find out about its green credentials.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

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.

In the aftermath of our recent awareness raising, Construct Ireland began to research what measures the Irish government was taking to prepare for the Energy directive, and how this compared with views from other EU member states, an investigation that is revealing startling results.
