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.

Lenny Antonelli takes a look at some of the entrants of the 2009 Solar Decathlon, a competition that challenges university teams from around the world to design and build homes that capture the sun’s energy.

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.

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.

As interest in sustainable building continues to escalate, Construct Ireland is increasingly unearthing buildings that betray an ambition to break new ground under a plethora of green criteria. John Hearne visited one such house in County Louth, and found a project driven by passive house and BER scale-topping ambitions combined with on-site energy and water supply strategies and a commitment to the use of green materials

Up till now, the activities of semi-state energy companies like Bord na Móna, ESB & Bord Gais have not won the favour of environmentalists. Richard Douthwaite explains how that situation is destined to rapidly change, and exclusively reveals details of the ambitious new green direction being adopted by Bord na Móna.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Construct Ireland’s John Hearne discovers a low energy, low carbon house being built in Galway which is achieving sustainable results whilst not jarring with aesthetic conventions.
