Ireland's most airtight house?

An experienced timber framer with an eye for detail, Tim O'Donovan set about building a low energy stick-built home in the Cork countryside and achieved a staggering level of airtightness.

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!

Brian Homan, Joint Managing Director of leading consulting engineers Homan O’Brien Associates describes a nursing home currently being built that is adopting a sustainable building approach to deliver healthy, comfortable accommodation at low running costs.

Lenny Antonelli visited a recently refurbished complex of social housing flats in Galway city that has combined excellence in urban regeneration with energy efficiency and major strides towards sustainability
Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

The emergence of climate change as a serious concern has helped create a burgeoning market for a vast range of eco technologies. All too often, however, the basic principles of sustainable design are ignored or misunderstood. Chris Croly of mechanical and electrical engineers Building Design Partnership describes the detail of a building which reveals a no-nonsense attention to sustainability.

Intended as a landmark not only architecturally, Áras Chill Dara sets an example for large scale sustainable building, as Construct Ireland’s Jason Walsh found out.

Innovative low energy construction is rarely recognised on a European scale. The Isover Energy Efficiency Awards are one exception — here are nominations from across the continent that were celebrated at the European awards ceremony in Barcelona on 2 June


John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.
While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.
