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.

The winner of the sustainability award at the 2011 Irish Architecture awards, Roebuck Castle student residence at UCD’s Belfield campus is also the biggest certified passive house project built to date in Ireland and the UK. Tony Rigg of Kavanagh Tuite Architects explains how such a significant building achieved passive results.

As of 2006 there is more and more talk in Ireland about the house of tomorrow and some very progressive houses have been built that go far beyond the basic legislative requirements for modern housing. Among them is Baile Glas, a development of twelve social and affordable housing units in Lombardstown, County Cork, initiated by the Blackwater Resource Development Agency and Cork County Council. Construct Ireland’s Jason Walsh finds out more.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

The groundbreaking Gaelscoil an Eiscir Riada, Tullamore, Co. Offaly was the first project to comprehensively draw from the Department of Education & Science’s DART (Design Awareness Research and Technology) programme, delivering a sustainable research project on school design.

For the first time in several years, 2007 will see a budget deficit in Ireland so the question must be asked: where does this leave state aid for sustainable building? Construct Ireland’s Jeff Colley and Jason Walsh propose a new approach to improving the energy efficiency of existing homes that might even fix a few of the difficulties seen in the last eighteen months

Kevin O’Flaherty’s development overlooking Galway Bay combines impressive energy saving techniques with the sorts of features that buyers of high-spec homes have grown to expect, as John Hearne discovers.

Recently sold by private tender for over e1.3 million, the ECO House in Shankill, Co. Dublin exceeded auctioneers expectations, an indicative example of the shift from public curiosity to eagerness to invest in contemporary sustainable building.

An experienced timber framer with an eye for detail, Tim O'Donovan set about building a low energy stick-built home in the Cork countryside and achieved a staggering level of airtightness.
