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!

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.


Why Ireland’s failing treatment systems & septic tanks must be tackled

Two years ago Construct Ireland ran a case study on Mater Orchard, a Mercy Sisters convent building that successfully balanced cutting edge technologies with pragmatic green design. Such was the success of that building, its architects were commissioned by Mercy Sisters in Limerick to repeat the feat. John Hearne visited the freshly completed building to find out how they fared

A new public park on the northside of Dublin combines wind power and sustainable water management with environmentally sound materials and strategies to boost biodiversity, making it a standard-bearer in urban design. Lenny Antonelli visited the site

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.

It has long been anticipated that the cost of sustainable building will come down as it enters the mass market, benefiting from economies of scale and greater industry confidence in low impact techniques and technologies as they become more familiar. Jay Stuart, managing director of integrated sustainable design consultants Delap and Waller EcoCo reveals a Kildare housing project which is likely to rapidly accelerate this process, and convince even the most conservative elements of the industry that low energy, low carbon building can be achieved at little or no additional cost

The rapidly growing public interest in sustainable building is finally starting to impact on property developers. Bill Quigley of Nutech Consultants describes an innovative 200 house development currently on site in Co. Cork where forward-thinking developers J & W Leahy Brothers have decided that the market is ready for low energy, low CO2 buildings.
