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

Aine Mc Elhinney discovers that the threat radon poses to private water supply needs addressing to help prevent lung cancer deaths

At Tom Heneghan’s new development in Dromard, Belmullet, Co. Mayo, it’s a case of sixteen units down, eleven to go as Construct Ireland goes to press. Exceeding the thermal performance requirements of the Building Regulations by some 60%, these houses incorporate a range of innovative and affordable sustainable building technologies which together deliver high comfort, low energy living, as John Hearne reveals.

Two years ago Construct Ireland ran a case study on Mater Orchard, a Mercy Sisters convent building that successfully balanced cutting edge technologies with pragmatic green design. Such was the success of that building, its architects were commissioned by Mercy Sisters in Limerick to repeat the feat. John Hearne visited the freshly completed building to find out how they fared

The ESB's Home Insulation Scheme aimed to upgrade the homes of 1,000 pensioners on fuel allowance last year - it ended up reaching almost three times that number, reducing carbon emissions and improving the lives of many. Lenny Antonelli found out more.

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.

One thing householders don't want to fail is their wastewater treatment system – the pollution, the health hazard, the cost and not least the embarrassment factor are all potentially serious. And yet, one wastewater treatment system provider says that such failures are very likely. As Jason Walsh asks, is he right?

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

In this fifth & final article in the series, Joseph Little compares simulations of several internal insulation options on common wall types, with worrying conclusions.
