Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

Number Two Grand Canal Square office, completed in September 2009 and substantially occupied by law firm Byrne Wallace in August this year, set a landmark in commercial office development by combining world-class design with sustainability - reconciling the architecture of Daniel Libeskind with achieving both a Breeam Excellent rating and an A3 BER certificate. Paul Dunne, sustainability and M&E director for Arup, outlines some of the project’s history and its achievements

Architect Paul Leech explains why the new Navan Credit Union is arguably Ireland’s most innovative sustainable building to date, and outlines his hopes that the experience gained from this project can help the construction industry to realise sustainable building in Ireland.

The development of sustainable building in Ireland has had to wait for the public to become concerned about energy supply, climate change, and the implications of living in draughty, damp buildings.  Much of the established low energy know-how emanates from countries where cold winters drove innovation. Drawing from 50 years of research and development between the Canadian government and housing industry, the Super E programme may be just what Ireland needs, as John Hearne discovered at a new development in Rosslare.

John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

With the publication earlier this year of three reports on drinking water quality, urban waste water discharges, and implementation of the phosphorous regulations, the EPA’s Office of Environmental Enforcement(OEE) has presented an overview of water management by local authorities in Ireland. Presented as a package of reports, they paint a picture of how local authorities are doing in relation to the management of water resources in the country. Construct Ireland’s Jeff Colley speaks to Doctor Matt Crowe, Programme Manager of the OEE on the state of national water quality.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Iain Douglas, President of the Irish Planning Institute reveals his views on the state of planning in Ireland, and the factors which could not only damage the environment in Ireland, but also cause social segregation, and aid unsustainable development across Ireland

Much hope has been pinned on the development of new technologies for sinking carbon and generating low impact energy. Richard Douthwaite reveals the major contribution that could be offered by something very old; a soil type that has been in use for 6,000 years.

Bank of America Tower, to be located at One Bryant Park in midtown Manhattan is a US$1 billion project that has been designed to be one of the most highly efficient and ecologically friendly tall buildings in the world. The building, currently under construction, is expected to be complete in 2008.

Jason Walsh got in touch with Cook + Fox Architects in New York, designers of the Bank of America Tower to see how the practice plans to square the circle of designing an environmentally sound high-rise building.
