Renovated agricultural barn marries its traditional look with modern green features

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

It’s not surprising that a 1970s bungalow on an exposed north-facing site might be draughty and burdened with high energy bills - but external insulation, a new heating system and a brand new roof can make all the difference. Lenny Antonelli reports.

After a long struggle to build their home, Karen and Steve Ward finally got their wish — an energy efficient, timber frame house that boasts a palette of healthy and ecological materials and a fully renewable heating system.

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

‘Interest in sustainable construction, both from private sector individuals and businesses and from the public sector has grown rapidly in the last couple of years. Unfortunately the ability of the industry to respond to this interest is under developed’ – Tom Woolley.

Nothing focuses the mind like a target. The growing impact of Building Energy Ratings (BER) is increasingly encouraging Irish people to aim for the highest energy rating they can. Patrick and Niamh Daly’s house in Mullingar takes this trend to the next level, using a myriad of sustainable green materials and technologies to become a net energy producer and go beyond the limit of the BER scale. John Hearne visited the nearly completed house to find out more.

The market for new residential build may have bottomed out, but compared to the rest of the construction industry the sustainable building sector appears buoyant. Changing market conditions, various government incentives and updated building regulations are all helping greener building companies - but with few houses likely to be built this year and capital restricted, challenges still lie ahead.

If one was to draw a conclusion on how seriously sustainability is being taken at government level using the number of occurrences of the word "sustainable" in policy documents, housing guidelines and speeches from Ministers, it would come across that Ireland's on a sound sustainable footing.
