The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

As the new-build sector grinds to a halt a window of opportunity has opened for builders, architects and other construction service providers – refurbishing Ireland’s existing housing stock. Jason Walsh visited an end-terrace house in inner city Dublin to see just how significant the improvements can be.

Patrick Daly  highlights that the energy refurbishment of our existing housing stock must become a priority. Daly has undertaken a retrospective DEAP case study assessment of an example house and its BER ratings, with staggering results.

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?
