John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.

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.

Everyone knows that the cheapest way of doing something can turn out to be very expensive in the end. The decision to make Ireland ’s electricity system so reliant on gas is about to bear this principle out. By Richard Douthwaite.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

A striking new house in County Cork proves that meeting the passive house standard needn’t mean sacrificing good design

It could be a reflex response to the shockingly poor construction standards that came to define Ireland’s boom years, but the world’s leading low energy building standard is starting to thrive in Ireland. As the several case studies following this article reveal, a groundswell of Irish clients, designers, contractors and manufacturers are starting to recognise the opportunities available in becoming early adopters of a standard destined for exponential global growth.

On 7 June 2011 environment minister Phil Hogan TD signed the latest changes to Part L of the building regulations into law, which will make it mandatory for all new homes to be 60% more energy efficient than the standards at the peak of the construction boom. Jeff Colley sheds some light on the key changes

Everyone agrees that the standard of building materials must be maintained but is localised technical certification resulting in a death of innovative and environmentally friendly building products and systems reaching the Irish market? Construct Ireland's Jason Walsh & Jeff Colley investigate.

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.
