Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

As the January 2006 deadline for implementation of the EU Directive on the Energy Performance of Buildings draws ever nearer, the Irish Government has spelt out its plans to delay the across the board introduction of building energy ratings until 2009. But how does this compare to other EU Member States?

Sustainable Energy Ireland's House of Tomorrow grant aid scheme has been successful in driving up standards in Irish residential building. Why, then, ask Construct Ireland’s Jason Walsh and Jeff Colley, are the residents in most need of the economic benefits brought by the scheme being left out?

Often regarded as a comfortable stopover for those travelling between Limerick and Killarney, the town of Adare has seen it’s profile upped considerably in recent years with the wonderful restoration and overhaul of the nearby Adare Manor Hotel

More and more businesses are looking to alternative energy sources to light, heat and cool their buildings but few have made a commitment to cutting carbon emissions to match Newbridge Silver, a silverware manufacturer in County Kildare. Jason Walsh visited the factory to find out more.

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.

On 7 June 2011 environment minister Phil Hogan TD signed the latest changes to Part L of the building regulations into law, which will make it mandatory for all new homes to be 60% more energy efficient than the standards at the peak of the construction boom. Jeff Colley sheds some light on the key changes

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.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.
