A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

Completed in October 2006 the headquarters of the Netherlands chapter of the World Wide Fund for Nature (WWF) is nothing if not a striking building. It also happens to be one of the single most sustainable buildings created in recent years. Construct Ireland continues its series of examining internationally significant sustainable buildings, with Jason Walsh putting questions to the building's architects, Amsterdam-based RAU.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

Martin Murray, chairman of the Passive House Association of Ireland and founder of Martin Murray Architects, explains why the world’s leading energy efficiency standard is on the up in Ireland

Everyone knows that the cheapest way of doing something can turn out to be very expensive in the end. The decision to make Ireland ’s electricity system so reliant on gas is about to bear this principle out. By Richard Douthwaite.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

In line with a growing consumer demand, the availability of green products is constantly increasing, leading to a situation where product quality need not be compromised in a search for a more eco friendly interior, as Jill Phillips of zero4zero7 interior design explains.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.
