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

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

With great attention to energy, materials and water, ABK Architects’ new civic precinct shows that smart green design can show no sign of compromise

Renovated agricultural barn marries its traditional look with modern green features

With the building of a new house in Greystones, County Wicklow, Ireland has become only the third country to feature the work of Frank Lloyd Wright. Jason Walsh visited the site to see if Wright's designs might just represent the kind of thinking required in today's energy-conscious buildings.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures. 

Designed and patented by Irish firm NuTech Renewables, solar enhanced ventilation aims to bring big energy and cost savings to the retrofit market by combining solar and ventilation technologies. NuTech’s Bill Quigley explains how it works.

Developers across Ireland are beginning to see the sense in shifting from individual heating systems to centralised energy production feeding into district heating networks. John Hearne visited a mixed-use scheme in Ballisodare, County Sligo, where a cutting edge biomass energy centre is providing a multitude of different buildings with energy from a green, secure source.

Ireland — along with much of the western world — relies on the International Energy Agency‘s oil production forecasts. But are they reliable, asks Lenny Antonelli?
