In light of the failure of AER 5 and the widespread pessimism in the wind industry regarding converting AER 6 contracts into operating wind farms, we asked the six main political parties what their proposals are for the development of an Irish wind industry.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

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.

Richard Douthwaite looks at the viability of heat pumps, and the factors that could determine their future role in a changing energy landscape.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

With the goal of achieving zero carbon standards for new homes by as soon as 2013, environment minister John Gormley has committed to introducing 60 per cent energy and carbon reductions under changes to part L of the building regulations next year. John Hearne spoke to leading industry figures to find out how the revised regulation could raise standards for both new and existing homes.

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

High levels of external insulation, abundant natural light and a minimalist approach to ventilation are ensuring that Malahide Lawn Tennis and Croquet Club is as green as its courts

The mainstreaming of sustainable building technologies is manifesting itself in a growing number of developers seeking to find the greener option. Jason Walsh describes a recent project where airtight timber frame construction meets high-tech solar thermal in a North Dublin House of Tomorrow funded scheme which is delivering low carbon results

Is it possible to ditch fossil fuels and run a 1970s Irish bungalow on solar energy? Norman McMillan’s renovated A1-rated bungalow in Carlow proves it is.
