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.

From the Construct Ireland archives
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!
The Active Solar House
Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.
Group effort
With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.
True to Form
Adding to the list of developers aiming to deliver energy efficient housing, Cronan Nagle Construction are currently on site with 188 highly insulated, airtight homes in Ennis, co. Clare. The development, which also incorporates heat recovery ventilation and condensing gas boilers is surpassing the thermal requirements of Building Regulations by up to 45%, as John Hearne discovers.
Zero waste
Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.
International selection
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
Renewed efforts
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.
Thin air
Independent integrated sustainable design consultant Xavier Dubuisson explains why heed must be paid to a recent study on the threats that misjudged energy upgrade work can pose to indoor air quality.
International
Green architect Minka McInerney profiles six unique green buildings including a cardboard school building, a globe-trotting recycled museum & the tallest timber building in the world
Anti social housing
Sustainable Energy Ireland's House of Tomorrow grant aid scheme has been successful in driving up standards in Irish residential building. Why, then, ask Construct Ireland’s Jason Walsh and Jeff Colley, are the residents in most need of the economic benefits brought by the scheme being left out?
