Solar Decathlon

Lenny Antonelli takes a look at some of the entrants of the 2009 Solar Decathlon, a competition that challenges university teams from around the world to design and build homes that capture the sun’s energy.
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!

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.
Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

Few words in the vocabulary of Ireland’s built environment come with more baggage than ‘bungalow’. For many people, it embodies a total disregard for good architecture and the environment, in part due to its association with isolated one-off housing. John Hearne visited a house in Mayo that mixes considered design with a host of modern technologies to breathe new life into the form.


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.

As energy prices continue to rise, the Irish construction industry is moving into uncharted territory, where all elements that affect energy performance—from orientation, to building design, to specification, to standard of workmanship—are increasingly recognised as key concerns.


U-value alone is a blunt instrument for gauging the thermal performance of a building. Ground-breaking eco architects Joseph Little and Benat Arregi of Building Life Consultancy explain why our increasingly ambitious insulation efforts must involve a rigorous attention to thermal bridging if we’re serious about creating low energy, healthy buildings.
