Richard Douthwaite explores the best options available to solve the intermittency problem of wind energy and help Ireland to harness its famously abundant natural resources

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.

Randy Ralston and Mel Cronin aimed for the passive house standard with their upgrade, and though they didn’t quite get there they ended up with a house that produces more energy than it consumes, making it one of the country’s flagship green renovation projects.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

Two years ago Construct Ireland ran a case study on Mater Orchard, a Mercy Sisters convent building that successfully balanced cutting edge technologies with pragmatic green design. Such was the success of that building, its architects were commissioned by Mercy Sisters in Limerick to repeat the feat. John Hearne visited the freshly completed building to find out how they fared

John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

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.

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.
