Retrofitting investment

The government is aiming to energy upgrade one million buildings by 2020, but huge investment will be needed to reach that goal as finance expert Jack O’Keeffe of Larchmont Consulting explains
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!

The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.

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.


On 7 June 2011 environment minister Phil Hogan TD signed the latest changes to Part L of the building regulations into law, which will make it mandatory for all new homes to be 60% more energy efficient than the standards at the peak of the construction boom. Jeff Colley sheds some light on the key changes

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.

Set in the shadow of Macgillycuddy's Reeks, Killorglin, County Kerry is a dramatic and rugged location best known as a tourist destination and home to Puck Fair. It’s also home, however, to one of Ireland’s most successful companies, FEXCO, which has opened its new low-energy corporate headquarters in the town.

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...

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.
