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

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

A new extension to the EPA's headquarters in Wexford lives up to the organisation's aim of environmental protection, boasting passive ventilation and lighting, a host of green technologies and a sustainable approach to landscaping.

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.

A cursory browse through Dublin Civic Trusts website and one is all too quickly reminded of the constant threat to our Architectural heritage

Nowhere demonstrates the need for a high-performance building envelope quite like a coastal site. John Hearne visited a cutting edge timber frame house overlooking Sligo Bay that was designed to achieve a highly insulated, air-tight and low embodied energy envelope whilst making the most of the spectacular vista.

Part of the Mater Hospital redevelopment, the recently completed Mater Orchard building is a first class example of how to integrate sustainable building strategies into a substantial building whilst keeping extra cost to a minimum.

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.

Until recently the York Street flats had been a living legacy of failed past approaches to social housing – a slum of mainly north-facing flats dating from Victorian times, and poorly rebuilt in the year Ireland became a republic, 1949. John Hearne visited the recently redeveloped York Street and found a thoroughly sustainable set of buildings that should inspire thoughts of future progress rather than past failings.

Historic buildings are all too easy to ignore when considering potential candidates for energy upgrade work. The heritage value of an historic building can often mitigate against the most obvious interventions, such as adding some form of wall insulation or replacing windows. Architect Fergal McGirl takes a typical Georgian building in Dublin through the energy rating process and proposes some considered upgrade measures.
