Construct Ireland tracked down the busy director of Limerick Civil Trust to talk about the sterling work already done, current projects and to ponder the implications of recent FAS cutbacks.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.

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.

The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.

In this adapted extract from his new book Natural Building: A Guide to Materials and Techniques, seminal eco architect Professor Tom Woolley outlines some of the reasons why natural building is necessary.

With over twenty years of design behind him, architect Martin Meyer has tackled plenty of big projects in his time, but his first home renovation challenge – to turn a dank 19th century red-brick house into a bright energy efficient home – was still eye-opening. Lenny Antonelli reports.

Architect Paul Leech explains why the new Navan Credit Union is arguably Ireland’s most innovative sustainable building to date, and outlines his hopes that the experience gained from this project can help the construction industry to realise sustainable building in Ireland.

Every eurozone government has debt problems and is cutting its spending, Richard Douthwaite says. Defaults and a prolonged depression are inevitable unless countries inject money into their economies in an unconventional way. A prosperous low-carbon economy would be the result

Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.
