From the Construct Ireland archives
Welcome to the archive of Construct Ireland, the award-winning Irish green building magazine which spawned Passive House Plus.
The feature articles in these archives span from 2003 to 2011, including case studies on hundreds of Irish sustainable buildings and dozens of investigative pieces on everything from green design and building methods, to the economic arguments for low energy construction.
While these articles appeared in an Irish publication, the vast majority of the content is relevant to our new audience in the UK and further afield. That said, readers from some regions should take care when reading some of the design advice - lots of south facing glazing in New Zealand may not be the wisest choice, for instance.
Dip in, and enjoy!
Retrofitting investment

If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.
Carrigaline passive house
A striking new house in County Cork proves that meeting the passive house standard needn’t mean sacrificing good design
Hidden Depths
Construct Ireland’s John Hearne discovers a low energy, low carbon house being built in Galway which is achieving sustainable results whilst not jarring with aesthetic conventions.
Heavy electricity
SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system
Green giant
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.
