Cork city split level timber frame house with passive solar design, rainwater harvesting, renewables & green material

High levels of external insulation, abundant natural light and a minimalist approach to ventilation are ensuring that Malahide Lawn Tennis and Croquet Club is as green as its courts

Construct Ireland meets former TD and MEP Brendan Halligan in his Baggot Street office to discuss the “appalling” state of the country’s building stock, and how Ireland can become a world leader in wind energy.

The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.

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

Brian Homan, Joint Managing Director of leading consulting engineers Homan O’Brien Associates describes a nursing home currently being built that is adopting a sustainable building approach to deliver healthy, comfortable accommodation at low running costs.

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

Energy Minister Eamon Ryan recently announced a e9 million fund to be administered by SEI for sustainable housing including, crucially, micro-generation of renewable electricity. Jason Walsh talked to SEI and industry figures to examine the scheme’s future.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.
