Until recently the York Street flats had been a living legacy of failed past approaches to social housing – a slum of mainly north-facing flats dating from Victorian times, and poorly rebuilt in the year Ireland became a republic, 1949. John Hearne visited the recently redeveloped York Street and found a thoroughly sustainable set of buildings that should inspire thoughts of future progress rather than past failings.

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

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.

Mixing excellent thermal performance with renewable heating, efforts to boost biodiversity and plans for micro-generation, a new timber frame house in rural Cork shows that both appealing design and low environmental impact can be achieved with one-off rural housing.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

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.

Interhabs, a company who build to the highly energy efficient Canadian Super E programme, have recently entered the Irish house building market.
Jeff Colley speaks to Ronan Long , General Manager of Interhabs Ireland, about the reasons why he believes Interhabs will bring energy efficient, comfortable, healthy homes to people across Ireland

In September, Sustainable Energy Ireland launched a major energy efficient housing development in Tuam, Co Galway. Houses in the development are over 70% more energy efficient than houses built to standard Building Regulations requirements. Construct Ireland’s John Hearne describes.
