No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building

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.

In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

Ireland ’s reliance on fossil fuel sources for electricity generation places the whole country on unstable ground as these limited resources dwindle

Sustainable Energy Ireland's House of Tomorrow grant aid scheme has been successful in driving up standards in Irish residential building. Why, then, ask Construct Ireland’s Jason Walsh and Jeff Colley, are the residents in most need of the economic benefits brought by the scheme being left out?

The Orchard, a new building on the campus of Stranmillis College, a teacher training college in Belfast, has become the first winner of a sustainable planning award organised by the Royal Town Planning Institute alongside a host of other awards. Jason Walsh visited the new building to find out about its green credentials.

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

Construct Ireland spoke to Adi Roche to find out about the progress so far, and the need for continuing support.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack
