The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.

With the age of cheap and abundant fossil fuel energy coming to an end, district heating, where a development is heated from a single, centralised heat source is becoming an increasingly attractive option due to the capital and running cost, efficiency and environmental benefits it can offer. Paraic Davis of Davis Associates mechanical and electrical engineers explains why district heating has become a viable and increasingly popular choice in Ireland.

A new extension to the EPA's headquarters in Wexford lives up to the organisation's aim of environmental protection, boasting passive ventilation and lighting, a host of green technologies and a sustainable approach to landscaping.

Turning a ruined farm house into a usable dwelling has been a dream for decades, but can an age-old structure really be brought-up to the cutting edge of energy efficiency? Architect Frank Cooney has found a way with a ruin in Cavan currently undergoing renovation. Jason Walsh visited the site to find out more.

With banks in America and the UK encountering major difficulties as previously booming economies head towards recession, a similar and perhaps even worse fate may be awaiting Irish banks. Worryingly, the situation is shaping up to be so bad, that the very future of the banks may be under threat, as Richard Douthwaite explains.

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.

Commercial, industrial and institutional buildings use a great deal of energy to ensure the comfort of the occupants and the efficient operation of their businesses. Building Energy Management Systems (BEMS) enable building owners to use this energy efficiently, as Sustainable Energy Ireland’s Chris Hughes explains

An advocate of sustainable building long before it was fashionable, Bill Quigley of NuTech Renewables has subsequently seen the mainstreaming of sustainability at first hand, having input into substantial projects for Leahy Bros, MKN and GEDA Construction amongst others. In their latest project, NuTech are working with Wicklow County Council on a social housing scheme with impressively high energy performance targets to meet, as Quigley explains.

Although not a particularly sustainable building in many regards, there is much environmental merit in the Dominic Stevens designed Mimetic House, a 1300 Sq. ft structure built for e120,000  near Dromahair, Co. Leitrim. The house’s builder Conor McManus of GreenTek Construction, specialists in building highly ecological, low energy, airtight homes and extensions, describes the sustainable aspects of the house.

It could be a reflex response to the shockingly poor construction standards that came to define Ireland’s boom years, but the world’s leading low energy building standard is starting to thrive in Ireland. As the several case studies following this article reveal, a groundswell of Irish clients, designers, contractors and manufacturers are starting to recognise the opportunities available in becoming early adopters of a standard destined for exponential global growth.
