Renewable Energy

John Hearne explains how truly low energy buildings can succeed or fail depending on how they engage with their occupants.

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 introduction of smart metering later this year presents a great opportunity to engage Irish people en masse into substantially reducing their energy consumption, simply by showing them how much electricity they’re consuming, and how much the cost varies at different times of the day. However, as Richard Douthwaite warns, there is a real risk that smart metering may come in a form that benefits the electricity companies and not the end-user.

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.

John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.

Government incentives are crucial to sparking a massive energy upgrade of our housing stock, but practical examples are just as important. Keen to push his home's energy performance to the limits, one Dublin homeowner overhauled his entire building fabric and installed renewable heating systems and heat recovery ventilation. Lenny Antonelli visited the house.

Up till now, the activities of semi-state energy companies like Bord na Móna, ESB & Bord Gais have not won the favour of environmentalists. Richard Douthwaite explains how that situation is destined to rapidly change, and exclusively reveals details of the ambitious new green direction being adopted by Bord na Móna.

Richard Douthwaite explains how inadequate conventional energy generation is and reveals the potential that combined heat and power & energy service companies can offer.

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.

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.
