Air-tightness is a key factor in any low energy build, but is often overlooked in comparison to energy sources and insulation. Lenny Antonelli examines how air-tightness is achieved in buildings, from design stage down to the final sealing

The Transition Towns movement has recently come to the fore as a model for sustainable development, with communities around the world signing up to reduce carbon emissions and build resilience in a world where climate change and energy security are emerging as real threats. Leading eco designer Joseph Little of Joseph Little Architects describes how the recent refurbishment and extension of a Dublin house addresses many of the movement’s concerns.  

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.

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.

As oil prices surge and the need to rapidly switch to energy sources that are secure and environmentally friendly becomes increasingly apparent, more and more Irish people are tapping into the renewable energy resources at their disposal. But are the Government giving people the incentive to make the switch?

Kevin O’Flaherty’s development overlooking Galway Bay combines impressive energy saving techniques with the sorts of features that buyers of high-spec homes have grown to expect, as John Hearne discovers.

Richard Douthwaite reveals that oil and gas peak are barely mentioned in the Government's recent energy Green Paper.

Chris Croly from BDP outlines the low energy and renewable energy strategies used in University College Cork’s new Environmental Research Institute, a test bed for the design and performance of sustainable buildings, which is ideally suited to housing the 200+ environmental projects carried out by its researchers.

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.

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?
