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.

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

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

Jason Walsh visited the Green Building, a pioneering sustainable development built in Dublin's Temple Bar in 1994, to find out how one of Ireland’s most ground breaking eco designs has been performing over the last decade.

The government recently announced a fund of e100 million for energy upgrading Irish houses in 2009, to be divided equally between low income and middle income earners. Focusing on the latter, Jason Walsh looks at the details of the Home Energy Saving scheme and speaks to key figures in the industry to get their views on the ingredients needed to make the scheme a success

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.

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.
