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.
Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.
The development of sustainable building in Ireland has had to wait for the public to become concerned about energy supply, climate change, and the implications of living in draughty, damp buildings. Much of the established low energy know-how emanates from countries where cold winters drove innovation. Drawing from 50 years of research and development between the Canadian government and housing industry, the Super E programme may be just what Ireland needs, as John Hearne discovered at a new development in Rosslare.
In recent years it’s become increasingly accepted that the age of cheap and abundant oil and gas supplies is coming to an end, and that future energy needs will have to be met from cleaner, more widely available fuel sources. According to Richard Douthwaite, the prospects of exponentially rising costs and failure to ramp up carbon capture and storage will mitigate against coal’s ability to take up the slack
John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.
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.
Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.
Earlier this year constructireland.ie broke the news of the introduction of the pilot Home Energy Saving Scheme, a new grant funding programme designed to stimulate the en masse refurbishment of Ireland’s poorly performing existing housing stock. John Hearne travelled to one of the pilot areas to see how the scheme is working on the ground, and discover how the scheme is developing.
The announcement in 2007 of the introduction of Smart electricity metering led to widespread hope that Ireland could set a global example by empowering consumers to cut electricity use and generate their own renewable electricity. John Hearne investigates current progress on the initiative, and discovers signs that Ireland’s approach to smart metering could represent a missed opportunity.
RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.
