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.

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.

Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.

When it comes to redeveloping old buildings, green designers face two choices: replace existing structures with modern, energy efficient buildings or refurbish and avoid the embodied energy and waste of demolition and new construction. Lenny Antonelli visited a redeveloped convent in Booterstown, County Dublin that combines the best of both approaches.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.

In 2005 Construct Ireland profiled the timber frame extension to Hannah and Martin Naughton’s Meath cottage. Five years later we’re returning to profile the upgrade of the original bungalow — a renovation that demonstrates how to detail dry lining without running the risk of mould growth

As the en masse energy upgrading of Irish homes and other buildings takes-off on an unprecedented scale, there are real dangers that even conscientious clients, professionals and contractors will make decisions that fail to save energy and create unhealthy buildings. Pioneering green architect Joseph Little, draws from the research and experience of his architectural practice & Building Life Consultancy to offer advice that should be heeded before any energy upgrade.
