In September, Sustainable Energy Ireland launched a major energy efficient housing development in Tuam, Co Galway. Houses in the development are over 70% more energy efficient than houses built to standard Building Regulations requirements. Construct Ireland’s John Hearne describes.

“Electrical waste is one of the fastest growing waste streams in Ireland. It is a source of valuable materials which can readily be recycled and which we must divert from landfill”, Minister Martin Cullen, 19 February 2003.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.

An advocate of sustainable building long before it was fashionable, Bill Quigley of NuTech Renewables has subsequently seen the mainstreaming of sustainability at first hand, having input into substantial projects for Leahy Bros, MKN and GEDA Construction amongst others. In their latest project, NuTech are working with Wicklow County Council on a social housing scheme with impressively high energy performance targets to meet, as Quigley explains.

A new house in west Cork offers a green vision for the future of Irish home building: not only is it A-rated, airtight and highly energy efficient, it’s built with ecological materials that are manufactured in Ireland too.

Completed in December 2009, Graham Group’s new headquarters reveal the construction and asset management company’s commitment to green building. The project’s sustainability adviser, Chris Croly of BDP describes an innovative design that pushes the boundaries of natural ventilation and takes a thoughtful approach to materials and buildings services to ensure a minimal environmental impact.

Prestige commercial buildings can place a heavy toll on the environment, typically relying in Ireland on carbon intensive grid electricity to power air conditioning systems throughout the warmer parts of the year and inefficient electric lighting – often all year around. Completed in November 2004, software company SAP’s Galway offices offer a rare opportunity to find out how a natural ventilated and low energy lighting building is working in practice, as John Hearne reveals.

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.

With oil prices remaining at ominously high levels in spite of sluggish economic growth figures and efforts by the International Energy Agency to release additional capacity, Ireland must act fast to cut oil usage. Why then, has the government withdrawn grants for renewables while continuing to subsidise oil and gas boilers?

Much hope has been pinned on the development of new technologies for sinking carbon and generating low impact energy. Richard Douthwaite reveals the major contribution that could be offered by something very old; a soil type that has been in use for 6,000 years.
