Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

Plans for the first Irish eco-village have been in the works since 1999, but – finally – work is well underway at The Village in Cloughjordan, Co Tipperary. Following a site visit in December, Lenny Antonelli gives an overview of the innovative project’s renewable energy district heating system and sustainable planning and community design approach, before profiling four of the first houses to be built.

The emergence of climate change as a serious concern has helped create a burgeoning market for a vast range of eco technologies. All too often, however, the basic principles of sustainable design are ignored or misunderstood. Chris Croly of mechanical and electrical engineers Building Design Partnership describes the detail of a building which reveals a no-nonsense attention to sustainability.

As the organisation entrusted by OECD countries to predict future global energy supplies, the International Energy Agency’s projections have significant impact on energy policy around the world. IEA officials recently told The Guardian that the organisation’s figures on oil supply had been inflated and that oil peak is happening. Richard Douthwaite assesses the fall out

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.

Conventional wisdom dictates that higher construction costs — for instance to reduce energy consumption and carbon emissions — would either squeeze developers’ profit margins or increase house prices. Tom Dunne, Head of DIT’s School of Real Estate and Construction Economics, reveals how misguided this view could be...

Many of the opportunities that trees offer for sustainable building are harnessed by a housing development in Ballymahon, Co. Longford which combines timber frame construction with recycled newspaper insulation and wood pellet heating. Adding in solar panels and attention to detail for airtightness, these low energy, low carbon homes reveal a developer who sees a bright future in going green. John Hearne visited the site to find out more.

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.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

Much of the debate on reducing international carbon emissions has focused on the extra cost of making the necessary cuts to slow the onset of climate change. According to Richard Douthwaite, the Irish Government is considering introducing Cap and Share, a system which would actually earn ordinary Irish people money for reducing emissions.
