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.

Built in 2004, Tomás O’Leary's house in Wicklow was the first in the country to be certified by the Passive House Institute — but how would it fare when subjected to a BER assessment six years later?

Designing sustainable buildings doesn’t always mean hi-tech solutions. From green roofs to living walls to constructed wetlands, sometimes it’s just a matter of embracing natural solutions. Lenny Antonelli investigates the emerging technologies and designs that use nature to improve the performance of buildings.

Ever since the seminal Agenda 21 was endorsed by 150 nations including Ireland in 1992, increasing lip service has been paid to sustainable development in everything from government policy to manufacturers’ claims. However, as John Hearne describes, in Tralee Town Council’s Rath Oraigh housing development, local action has been taken with not only local, but global benefits that embody the principles of sustainable development.

Conventional wisdom dictates that higher construction costs — for instance to reduce energy consumption and carbon emissions — would either squeeze developers’ profit margins or increase house prices. Tom Dunne, Head of DIT’s School of Real Estate and Construction Economics, reveals how misguided this view could be...

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 worl­d has learned the hard way that our political leaders lacked the judgement and resolve to identify and address the problems which led to the recession. Richard Douthwaite argues that a similarly flawed judgement is evident in the assumption that the economy will recover, and advises on how to prepare for a future of global economic contraction.

‘‘We have a body of extremely experienced and competent staff who will be able to hit the ground running”

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.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.
