The desire for better insulated, more environmentally friendly homes is driving ever more Irish self-builders to investigate alternatives to traditional block building. Jason Walsh visited a contemporary style factory-built timber frame house built in County Waterford in 2005.

Much of the debate on reducing international carbon emissions has focused on the extra cost of making the necessary cuts to slow the onset of climate change. According to Richard Douthwaite, the Irish Government is considering introducing Cap and Share, a system which would actually earn ordinary Irish people money for reducing emissions.

Imaginosity, the new children's museum building in Sandyford's Beacon South Quarter development, is getting the Austrian eco-house treatment, combining low energy, modular construction with a plethora of low carbon energy technologies. Jason Walsh visited the site to take a look.

Kirk Shanks, Senior Researcher at the Sustainability Research Development Group, the Focas Institute, DIT describes the development of this new sustainable generation.

Public private partnership schemes have come to dominate many aspects of Irish infrastructural development, from toll roads to urban regeneration schemes. Jason Walsh asks if they amount to privatisation by stealth and whether they come at too high a social and environmental cost.

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.

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.

The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.

In the second installment of a new feature on international green buildings, Lenny Antonelli takes a look at four innovative, sustainable and striking buildings from around the world.

The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.
