Richard Douthwaite explains why the bailout may turn out to be a gift to Ireland, and offers some advice for dealing with a default.

A sustainable building must address more than energy, carbon or materials, argues Irish born architect Stephen Roe of up-and-coming London architects Roewu – it must respond to its environment. Not only does Roe’s design for the All Weather House achieve that, it boasts green materials, renewable heating and generous insulation too.

Ireland's first passive house development emerged as the big winner at the inaugural Isover Energy Efficiency Awards in February. We look at the winner and other finalists

Martin Murray, chairman of the Passive House Association of Ireland and founder of Martin Murray Architects, explains why the world’s leading energy efficiency standard is on the up in Ireland

As it nears completion, John Hearne visits what is anticipated to be one of the lowest energy buildings in Ireland's recent history.

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable

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.

As policy makers start to set mandatory low energy and renewable energy requirements as conditions of planning, the ability of the construction industry to find sound low-cost ways of achieving the new standards is becoming a key factor. John Corless speaks to leading sustainable building consultant Jay Stuart of Delap & Waller EcoCo and Paul Gilmartin of Ecobead to discover an approach with enormous potential for en-masse usage.

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

Heat recovery ventilation, a technology that has become a standard building application in Scandinavian countries, is rapidly gaining recognition in Ireland as a solution to both problems.
