The Dwelling Energy Assessment Procedure (DEAP) is now the national methodology for creation of Building Energy Rating (BER) Certificates for new dwellings in Ireland, and is an important desk top tool for predicting the performance of projects at outline design stage.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Atop a hill in New Ross, County Wexford, is a beacon for sustainability in large-scale developments, which draws extensively from across the palette of sustainable building options to achieve a building that is notable not just aesthetically, but also in health, energy and environmental impact terms. Jason Walsh visited the new Solar Croi spa, part of the Brandon House Hotel, Health Club and Spa, to find 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.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

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.

An increasing number of sustainable homes are being built in Ireland but many of them are in rural areas, and yet, Ireland is an increasingly urban society. Jason Walsh looks at one recent attempt to renovate a small terraced house in inner-city Dublin, bringing it up to modern environmental and energy efficiency standards.

Recent allegations that a single leaf timber frame development in Leitrim was forced to incorporate an outer layer of blockwork in spite of no such requirement in the Building Regulations or by the local authority in question suggests that something is seriously amiss, as Frank Coles explains.

Up to 150,000 workers are at potential risk of developing fatal lung cancer as a result of exposure to dangerously high levels of radiation, while a leading radon expert has cited ‘widespread confusion amongst employers’ regarding their legal requirements.

Construct Ireland’s John Hearne discovers the growing shift towards making sites independent in terms of both water supply and wastewater treatment.
