Renewable Energy

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

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.

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.

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.

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.

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

Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

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

The first scheme of renewable energy grants for Irish homeowners, the Greener Homes Scheme, was launched on Monday 27th March 2006 and will make grant funding available to homeowners looking to install renewable energy heating technology

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.
