The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.

Since establishing UCD’s Energy Research Group in 1975, the career of Professor J Owen Lewis has taken in the role of principal at the UCD College of Engineering, Mathematical and Physical Sciences, a Bord na Móna R&D directorship and expert roles advising EU research, national energy policy and building regulations. Appointed CEO of SEAI last year, Professor Lewis has been a champion of sustainable building since before the term existed. His selection combines a proto-green Alvar Aalto design, the reimagined Reichstag and an unusual academic building with two new cutting edge sustainable buildings.

A marked lack of adequate central government action to promote sustainable house building in Ireland has been recently counteracted by planning authorities such as Fingal County Council taking action into their own hands, and setting standards geared to protect their constituents in an oil and gas scarce future. However, as sustainable building consultant Will Woodrow discovered from surveying planning authorities around the country, local government willingness is not always met with a full grasp of the issues needed to make sustainable housing happen.

With the goal of achieving zero carbon standards for new homes by as soon as 2013, environment minister John Gormley has committed to introducing 60 per cent energy and carbon reductions under changes to part L of the building regulations next year. John Hearne spoke to leading industry figures to find out how the revised regulation could raise standards for both new and existing homes.

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.

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.

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

A sustainable energy project in north Tipperary has the potential to create a pioneering green community – buildings are getting energy makeovers, grants are available for renewables and the ecovillage at Cloughjordan is under construction. But getting householders in the area to go green is still proving a hard sell, as Lenny Antonelli reports

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.
