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 fears grow amongst climate scientists that the world may be close to reaching a tipping point leading to runaway global warming, there’s a growing recognition that the forthcoming UN climate conference in Copenhagen must deliver dramatic and binding targets to cut carbon. According to Richard Douthwaite, the talks are unlikely to deliver sufficiently meaningful action.

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.

There are surprisingly few truly iconic buildings, structures that dominate their environs, not to mention the country's intellectual landscape. Halla Chontae Chorcai, Cork County Hall, is one such building. Construct Ireland's Jason Walsh visited to find out about the building's environmental credentials.

The building is the first all timber office complex in Ireland. It covers almost 2,300m2 of floor space and provides accommodation for almost 100 staff working in a wide range of forestry related disciplines.

With over twenty years of design behind him, architect Martin Meyer has tackled plenty of big projects in his time, but his first home renovation challenge – to turn a dank 19th century red-brick house into a bright energy efficient home – was still eye-opening. Lenny Antonelli reports.
