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

 

If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.

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

If you are at all worried about keeping construction costs down and lengthening the useable lifespan of your building, it’s critical that energy performance is considered from the earliest stages of planning and design. John Hearne spoke to a number of leading Irish experts in sustainable design about following simple principles of orientation, form and layout to achieve substantial energy improvements for free

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.

Assessing the Impact on Agriculture of Predicted Changes in Irish Climate by Dr Nicholas Holden

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.

Ireland — along with much of the western world — relies on the International Energy Agency‘s oil production forecasts. But are they reliable, asks Lenny Antonelli?

It has long been anticipated that the cost of sustainable building will come down as it enters the mass market, benefiting from economies of scale and greater industry confidence in low impact techniques and technologies as they become more familiar. Jay Stuart, managing director of integrated sustainable design consultants Delap and Waller EcoCo reveals a Kildare housing project which is likely to rapidly accelerate this process, and convince even the most conservative elements of the industry that low energy, low carbon building can be achieved at little or no additional cost
