If achieving eco buildings is challenging for new build, it is doubly so for renovation projects. Philip & Delphine Geoghegan of iCon Architecture & Uban Design describe a low impact renovation that balances these apparent tensions with great success.

With some of the most impressive moves toward sustainability over the last few years coming in the form of planning requirements, it should come as no surprise that many local authorities are pioneering energy efficient housing in their own housing stock. Jason Walsh visited a site in Oldtown, County Dublin, to see how Fingal County Council is putting sustainability into practice with help from Keenan Timber Frame, Ecological Building Systems, Nutech Renewables and others

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

The announcement in 2007 of the introduction of Smart electricity metering led to widespread hope that Ireland could set a global example by empowering consumers to cut electricity use and generate their own renewable electricity. John Hearne investigates current progress on the initiative, and discovers signs that Ireland’s approach to smart metering could represent a missed opportunity.

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

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

Tom Woolley, Professor of Architecture at Queens University Belfast and Editor of the Green Building Handbook, draws attention to the recent event which demonstrated the potential and importance of sustainable building in Ireland.

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building

When the two worlds of heritage and development collide opinions frequently become polarised and fraught with difficulty. There are few more vexed issues, as Tim Carey, Heritage Officer with Dun Laoghaire Rathdown County Council reveals
