A new development at Grange Lough, Rosslare, reveals that passive houses can be made Irish – both in terms of what they’re built with, and how they look.

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle?

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.

Do termites apply building science better than humans? Award winning architect Sean Harrington takes a characteristically left-of-brain approach to our international feature, leading to some humbling lessons.

As the new-build sector grinds to a halt a window of opportunity has opened for builders, architects and other construction service providers – refurbishing Ireland’s existing housing stock. Jason Walsh visited an end-terrace house in inner city Dublin to see just how significant the improvements can be.

A new development in County Westmeath answers a nagging question about district heating: how to make it financially viable when it services energy efficient buildings.

Patrick Daly, co-founder of the RiSE (Research in Sustainable Environments) research unit in the DIT has undertaken an in depth study and critique of the current Irish Part L for energy efficiency in dwellings, comparing it in detail to the UK equivalent. The findings raise challenging questions about the Irish standards and methodology and highlight serious shortcomings in comparison to our UK neighbours, permitting substantially higher levels of CO2 emissions from new homes in Ireland than in the UK.
