Tall buildings tend to be among the worst offenders in terms of energy and environmental profligacy – but one new Viennese project shows that high rise doesn’t have to mean high environmental impact.

Circulation and readership aren’t the same thing, though some people conflate them.

Circulation’s easy to measure – if you’re willing to subject your magazine to the scrutiny of independent auditing – but readership’s another matter. So let’s deal with circulation first.

Leading Irish timber frame manufacturer Cygnum is launching a pioneering closed low embodied carbon panelised building system that integrates cellulose insulation.

The Precision system has been developed by the company to drive down the costs of a building system that’s becoming increasingly popular due to its thermal performance, healthiness and low environmental impact.

Ireland's first passive house development emerged as the big winner at the first inaugural Isover Energy Efficiency Awards in Dublin on Friday. The Grange Lough project — by developer Michael Bennett and Shoalwater Timber Frame — won first place in the competition and will now go on to Isover's European awards in Barcelona this June. This is the first time Ireland will be represented at the finals.

People planning to build a new home could save themselves thousands of euro each year by developing a passive house, according to the Passive House Association of Ireland (PHAI), a new low energy design initiative comprising passive house designers and contractors.

Ambitious companies in the Irish sustainable building sector should look to the US, says Century Homes founder Gerry McCaughey. As chief executive of LA-based green building business consultancy Infineco, McCaughey is witnessing first-hand how the land of opportunity is waking up to green construction.

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

As the new-build sector grinds to a halt a window of opportunity has opened for builders, architects and other construction service providers – refurbishing Ireland’s existing housing stock. Jason Walsh visited an end-terrace house in inner city Dublin to see just how significant the improvements can be.

Earlier this year constructireland.ie broke the news of the introduction of the pilot Home Energy Saving Scheme, a new grant funding programme designed to stimulate the en masse refurbishment of Ireland’s poorly performing existing housing stock. John Hearne travelled to one of the pilot areas to see how the scheme is working on the ground, and discover how the scheme is developing.

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.

“Electrical waste is one of the fastest growing waste streams in Ireland. It is a source of valuable materials which can readily be recycled and which we must divert from landfill”, Minister Martin Cullen, 19 February 2003.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

The groundbreaking Gaelscoil an Eiscir Riada, Tullamore, Co. Offaly was the first project to comprehensively draw from the Department of Education & Science’s DART (Design Awareness Research and Technology) programme, delivering a sustainable research project on school design.

Jason Walsh spoke to David Smith of O'Mahony Pike Architects about the practice's uniquely-designed show apartments for this year's Myhome.ie Spring House and Garden exhibition.

There are surprisingly few truly iconic buildings, structures that dominate their environs, not to mention the country's intellectual landscape. Halla Chontae Chorcai, Cork County Hall, is one such building. Construct Ireland's Jason Walsh visited to find out about the building's environmental credentials.
