While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

Not only does the new OPW-designed district veterinary office in Drumshanbo Co. Leitrim place strong emphasis on natural ventilation and lighting, it rests comfortably in the rural landscape and boats commendable green features too. Lenny Antonelli reports

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.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli

Plans for the first Irish eco-village have been in the works since 1999, but – finally – work is well underway at The Village in Cloughjordan, Co Tipperary. Following a site visit in December, Lenny Antonelli gives an overview of the innovative project’s renewable energy district heating system and sustainable planning and community design approach, before profiling four of the first houses to be built.

World record oil prices are being shattered so regularly that breaking news stories on the matter seem cliché, with other fossil energy sources heading in the same direction. Richard Douthwaite describes the first significant signs that Irish banks may be starting to take the issue on board regarding property lending.

In light of the current economic conditions, an increasing number of Irish people are turning away from buying new homes, instead deciding to make the most of what they’ve got by extending and refurbishing. Lenny Antonelli visited one such house nearing completion in Glasnevin that uses a combination of materials and techniques to aim for highly sustainable results.

Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.
