Passive assessment

Built in 2004, Tomás O’Leary's house in Wicklow was the first in the country to be certified by the Passive House Institute — but how would it fare when subjected to a BER assessment six years later?
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!

Richard Douthwaite explains why the bailout may turn out to be a gift to Ireland, and offers some advice for dealing with a default.

Completed in October 2006 the headquarters of the Netherlands chapter of the World Wide Fund for Nature (WWF) is nothing if not a striking building. It also happens to be one of the single most sustainable buildings created in recent years. Construct Ireland continues its series of examining internationally significant sustainable buildings, with Jason Walsh putting questions to the building's architects, Amsterdam-based RAU.

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.


Box-like, small windows, primary colour renders - there is a common misconception that building to the passive house standard involves sacrificing design freedom for the sake of thermal performance. Not so, argues passive house guru Tomás O’Leary of MosArt and the Irish Passive House Academy, as his selection of architecturally diverse buildings reveals.

The Daintree Building is a mixed-use, sustainable urban building on Pleasant’s Place, just off Camden St. Dublin , writes Brian O’Brien of Solearth Architects. Conceived in 1999 it has been a long development process—but by late September Daintree should be open for business and the ever innovative Daintree (Paper Co) Ltd will have a new home, one appropriate to the delightfulness of their products and their focus on nature’s generosity for their raw materials.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack


Developers across Ireland are beginning to see the sense in shifting from individual heating systems to centralised energy production feeding into district heating networks. John Hearne visited a mixed-use scheme in Ballisodare, County Sligo, where a cutting edge biomass energy centre is providing a multitude of different buildings with energy from a green, secure source.
