Semi-state business Bord Gáis have placed green innovation at the centre of their business strategy. As CEO John Mullins reveals, pay as you save and renewable energy will shape the company’s future.

In terms of 1972 money, oil prices averaged about six dollars a barrel between 1987 and 2000. Last October they reached $40. They are now around $50 a barrel which means that they are beginning to climb back into the territory which caused the global economy to crash in 1979/80.

Richard Douthwaite looks at the viability of heat pumps, and the factors that could determine their future role in a changing energy landscape.

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 Why then, has the government withdrawn grants for renewables while continuing to subsidise oil and gas boilers?

It is not alone as an artist and historical author of distinction that Peter Pearson is noted.  His role as a conservationist in the last three decades has had a tangible effect in protecting Ireland’s built heritage, and raising consciousness of the value and importance of conservation work

Lenny Antonelli visits a new residential development in rural Carlow that boasts only the second and third certified passive houses in Ireland, and encouragingly, finds that meeting and exceeding the coveted passive standard wasn’t as difficult as expected.

As the main attraction at the Spring House and Garden Show in the RDS earlier this year, the “Eco House” claimed to offer the house buying public an entirely ecologically sound new home, with considerations for energy efficiency, the environment and health evident in the design, structure, materials and technologies showcased in the house. Construct Ireland spoke to the house’s architect, John Goulding and Director of Century Homes, Paul MacDonald, who explain not only the technological considerations but the environmental demand for such a project.

John Goulding, the architect on the Eco House, has been actively involved in researching energy efficient design for the past 18 years, working through UCD’s influential Energy Research Group, and has worked on several European Commission funded research and building demonstration projects. He explains to Construct Ireland’s Jeff Colley how the Eco House performs.

Few concepts in sustainable design have caught on like the passive house. Since the construction of the first passive house in Germany in 1990, an estimated 15 to 20,000 houses have been built to what is arguably the world’s leading low energy building standard. Drawing from his experience in sustainable building since the early 1980s, Bill Quigley of NuTech Renewables posits an alternative approach.

Completed in October 2006 the headquarters of the Netherlands chapter of the World Wide Fund for Nature (WWF) is nothing if not a striking building. It also happens to be one of the single most sustainable buildings created in recent years. Construct Ireland continues its series of examining internationally significant sustainable buildings, with Jason Walsh putting questions to the building's architects, Amsterdam-based RAU.

During his tenure as energy minister Eamon Ryan instigated plans to energy upgrade Ireland’s draughty, damp housing stock. Ryan and his wife, writer Victoria White, show Construct Ireland how their own home has been given the green treatment, and architect Mike Haslam of Solearth describes the project.
