Carlow A1 upgrade

Is it possible to ditch fossil fuels and run a 1970s Irish bungalow on solar energy? Norman McMillan’s renovated A1-rated bungalow in Carlow proves it is.
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!

Is it possible to ditch fossil fuels and run a 1970s Irish bungalow on solar energy? Norman McMillan’s renovated A1-rated bungalow in Carlow proves it is.

Just outside the quiet rural town of Templepatrick, County Antrim, located ten miles north of Belfast, is a timber frame house that sets new standards for comfort and, the owners hope, sustainability. Jason Walsh visited the house and found a traditional aesthetic that belies its ultra modern sustainability features

Patrick Daly, co-founder of the RiSE (Research in Sustainable Environments) research unit in the DIT has undertaken an in depth study and critique of the current Irish Part L for energy efficiency in dwellings, comparing it in detail to the UK equivalent. The findings raise challenging questions about the Irish standards and methodology and highlight serious shortcomings in comparison to our UK neighbours, permitting substantially higher levels of CO2 emissions from new homes in Ireland than in the UK.

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.

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.


World record oil prices are being shattered so regularly that breaking news stories on the matter seem cliché, with other fossil energy sources heading in the same direction. Richard Douthwaite describes the first significant signs that Irish banks may be starting to take the issue on board regarding property lending.
