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.

Mellott’s Joinery, based in Mayo since 1857, has long been a specialist in Joinery. Construct Ireland grabbed Thomas Mellott for a quick chat about the company’s history and the techniques involved.

Two years ago Construct Ireland ran a case study on Mater Orchard, a Mercy Sisters convent building that successfully balanced cutting edge technologies with pragmatic green design. Such was the success of that building, its architects were commissioned by Mercy Sisters in Limerick to repeat the feat. John Hearne visited the freshly completed building to find out how they fared

With the publication earlier this year of three reports on drinking water quality, urban waste water discharges, and implementation of the phosphorous regulations, the EPA’s Office of Environmental Enforcement(OEE) has presented an overview of water management by local authorities in Ireland. Presented as a package of reports, they paint a picture of how local authorities are doing in relation to the management of water resources in the country. Construct Ireland’s Jeff Colley speaks to Doctor Matt Crowe, Programme Manager of the OEE on the state of national water quality.

Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.

Stricter air-tightness standards might be helping to reduce energy use in new build, but is it leading to higher indoor concentrations of chemical and biological toxins? Lenny Antonelli investigates an emerging approach to building that is combining attention to environmental impact with consideration for the potential health effects of modern building materials and practices.

As Construct Ireland goes to press, the construction industry awaits Ministers Dick Roche and Noel Dempsey to sign off the long overdue timetable for implementing the Energy Performance of Buildings Directive, a piece of legislation set to make energy performance a key factor in property sales. But can Ireland train up enough auditors to label buildings by January 2006?

Iain Douglas, President of the Irish Planning Institute reveals his views on the state of planning in Ireland, and the factors which could not only damage the environment in Ireland, but also cause social segregation, and aid unsustainable development across Ireland

In the third installment of a new feature on international green buildings, Lenny Antonelli takes a look at more innovative, sustainable and striking buildings from around the world.
