With the goal of achieving zero carbon standards for new homes by as soon as 2013, environment minister John Gormley has committed to introducing 60 per cent energy and carbon reductions under changes to part L of the building regulations next year. John Hearne spoke to leading industry figures to find out how the revised regulation could raise standards for both new and existing homes.

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

Construct Ireland’s John Hearne discovers a low energy, low carbon house being built in Galway which is achieving sustainable results whilst not jarring with aesthetic conventions.

The advent of central heating improved the comfort of life for countless Irish people over the past century, but as energy efficient building grows, some pioneering homeowners think they can live without it. What’s life like for them?

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

Fears are growing amongst energy rating trainers that Ireland is running out of time to ensure building energy ratings are in place for existing homes at point of sale or rental from January. Jeff Colley spoke to SEI and to leading figures involved in energy rating training to find out more and shed some light on how homes will be assessed.

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.

Construct Ireland’s John Hearne discovers the growing shift towards making sites independent in terms of both water supply and wastewater treatment.

In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack

In this fifth & final article in the series, Joseph Little compares simulations of several internal insulation options on common wall types, with worrying conclusions.
