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!

As the January 2006 deadline for implementation of the EU Directive on the Energy Performance of Buildings draws ever nearer, the Irish Government has spelt out its plans to delay the across the board introduction of building energy ratings until 2009. But how does this compare to other EU Member States?


Up to 150,000 workers are at potential risk of developing fatal lung cancer as a result of exposure to dangerously high levels of radiation, while a leading radon expert has cited ‘widespread confusion amongst employers’ regarding their legal requirements.

As of 2006 there is more and more talk in Ireland about the house of tomorrow and some very progressive houses have been built that go far beyond the basic legislative requirements for modern housing. Among them is Baile Glas, a development of twelve social and affordable housing units in Lombardstown, County Cork, initiated by the Blackwater Resource Development Agency and Cork County Council. Construct Ireland’s Jason Walsh finds out more.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.


Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.
