Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.

Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability

Closed-panel timber frame home in Wicklow with impressive thermal performance and airtightness

The building is the first all timber office complex in Ireland. It covers almost 2,300m2 of floor space and provides accommodation for almost 100 staff working in a wide range of forestry related disciplines.

Many of the opportunities that trees offer for sustainable building are harnessed by a housing development in Ballymahon, Co. Longford which combines timber frame construction with recycled newspaper insulation and wood pellet heating. Adding in solar panels and attention to detail for airtightness, these low energy, low carbon homes reveal a developer who sees a bright future in going green. John Hearne visited the site to find out more.

Up till now, the activities of semi-state energy companies like Bord na Móna, ESB & Bord Gais have not won the favour of environmentalists. Richard Douthwaite explains how that situation is destined to rapidly change, and exclusively reveals details of the ambitious new green direction being adopted by Bord na Móna.

In terms of 1972 money, oil prices averaged about six dollars a barrel between 1987 and 2000. Last October they reached $40. They are now around $50 a barrel which means that they are beginning to climb back into the territory which caused the global economy to crash in 1979/80.

In spite of the obvious emergence of technologies and design approaches to reduce the impact of new build, environmental standards remained poor throughout the duration of the housing boom. Now, a unique combination of political will, smart incentives, and a new market of informed and empowered buyers may be about to change that, writes Lenny Antonelli

Intended as a landmark not only architecturally, Áras Chill Dara sets an example for large scale sustainable building, as Construct Ireland’s Jason Walsh found out.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures.
