Results of a new five-year study of recycled concrete show that it performs as well, and in several cases even better, than conventional concrete.

Cement is responsible for up to 8% of global carbon emissions, and in this guide, sustainable design expert Jay Stuart looks at ways to minimise its environmental impact through good design, and at some of the alternative, lower carbon cement and concrete products on the market.

Quinn Building Products has become the first company in Ireland to attain an environmental product declaration (EPD) for a structural precast concrete product under the Irish EPD system.

Researchers at the Institute of Industrial Science at the University of Tokyo have developed a new procedure for recycling concrete with the addition of discarded wood.

Low carbon concrete blocks are now widely available on the Irish market – bringing up to 50% reductions in embodied CO2 – and Passive House Plus helped make it happen.

Architect Tom Duffy has long had an interest in green design, and working on a self-build project for himself and his wife he was able to prove a point: making a modest family home to the highest standards need not cost the earth.

Designing a dwelling to take advantage of the sun’s free heat is a big part of what makes a passive house passive. So how do you meet the low energy standard when your narrow site faces away from the sun and is overshadowed by neighbouring houses and trees, while simultaneously hitting an A1 building energy rating – and with a stunning, architecturally expressive design?

Traditional screeds require significant drying before the final floor covering can be installed, however, if this is not well planned for, it may well delay the completion of the entire project.

Any building, no matter how cold and draughty, no matter how remote, can be improved to world-class energy performance, as an upgraded and extended Donegal cottage dating back to the 1800s proves.

Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike. Leading green designer Joseph Little of Joseph Little Architects investigates the particular problems associated with dry-lining single-leaf concrete block walls

If one was to draw a conclusion on how seriously sustainability is being taken at government level using the number of occurrences of the word "sustainable" in policy documents, housing guidelines and speeches from Ministers, it would come across that Ireland's on a sound sustainable footing.
