Opinion - Is passive house going mainstream?

Archie O’Donnell, projects coordinator for Éasca and the Irish Passive House Association
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!

An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.
If you’re applying for planning permission to build in Cappagh, North Ballymun or Northwest Balbriggan, 30% of your heating must come from renewable energy, and your heating must be less than 50Kwh/m2 per annum—roughly twice the standard of most new homes.


The unprecedented development seen in Ireland in the Celtic Tiger years was fueled by the availability of cheap, abundant fossil energy. As the boom ends, the state is attempting to boost the economy with investment in larger than ever infrastructural projects which will not benefit many of the tax payers who are funding them, and crucially don’t recognize the extent to which peak oil production will affect their viability, as Richard Douthwaite reveals.

In the first installment of a new feature on international green buildings, Lenny Antonelli takes a look at five innovative, sustainable and striking buildings from around the world.
