Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

Tom Woolley, Professor of Architecture at Queens University Belfast and Editor of the Green Building Handbook, draws attention to the recent event which demonstrated the potential and importance of sustainable building in Ireland.

In light of Ireland’s poor performance in the recent European Environment Agency Report on drinking water quality, the issue of Ireland’s wastewater treatment from one off houses is poised to stay in the spotlight. Construct Ireland’s Pat Kennedy, environmental engineer, investigates.

The environmental impact of the built environment extends far beyond energy consumption and carbon emissions throughout a building’s intended lifespan. Architect and sustainable design consultant Sinéad Cullen of DW EcoCo & BE Architecture explains why there’s a need to design buildings that can be deconstructed rather than destroyed once they reach their end of life, and looks at the obstacles to be overcome to make this happen.

A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

Lenny Antonelli takes a look at some of the entrants of the 2009 Solar Decathlon, a competition that challenges university teams from around the world to design and build homes that capture the sun’s energy.

As the en masse energy upgrading of Irish homes and other buildings takes-off on an unprecedented scale, there are real dangers that even conscientious clients, professionals and contractors will make decisions that fail to save energy and create unhealthy buildings. Pioneering green architect Joseph Little, draws from the research and experience of his architectural practice & Building Life Consultancy to offer advice that should be heeded before any energy upgrade.

As more and more people upgrade their homes to make them more energy efficient, it’s crucial for them to consider installing some sort of ventilation system to keep them healthy. Astrid Madsen compares heat recovery ventilation to a relative newbie on the Irish market, demand controlled ventilation.

Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.

John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.
