Watford, just over 30 kilometres north of London, is now home to an aspirational new house, developed by an Irish company, designed to completely remove carbon emissions from the home. Jason Walsh visited the site to learn more
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!


Long-caricatured as resource destroying monsters clad in steel and glass, the skyscraper is rarely viewed as an environmentally sound form of architecture. Construct Ireland’s Jason Walsh looks at efforts underway to change that perception.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.


If the Irish construction industry is truly to rapidly embrace the concept of sustainability, leadership from the public sector will be paramount in setting the right example. John Hearne spoke to the design team of the Opus and RIBA award-winning Cork Civic Offices, a development which keeps carbon emissions and fossil energy consumption to a minimum, and once more puts the public sector at the forefront of innovative sustainable design

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.
As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

The Passive House standard, an internationally renowned approach to building that negates the need for conventional heating, has attracted considerable interest in Ireland recently as energy prices continue to rise. Vivienne Brophy, Dr Irena Kondratenko, Patxi Hernandez and Kevin Burke of UCD’s Energy Research Group look at the effect this approach could have on cutting Ireland’s energy consumption and CO2 emissions.
