If you are at all worried about keeping construction costs down and lengthening the useable lifespan of your building, it’s critical that energy performance is considered from the earliest stages of planning and design. John Hearne spoke to a number of leading Irish experts in sustainable design about following simple principles of orientation, form and layout to achieve substantial energy improvements for free

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.

The Dwelling Energy Assessment Procedure (DEAP) is now the national methodology for creation of Building Energy Rating (BER) Certificates for new dwellings in Ireland, and is an important desk top tool for predicting the performance of projects at outline design stage.

In light of the current economic conditions, an increasing number of Irish people are turning away from buying new homes, instead deciding to make the most of what they’ve got by extending and refurbishing. Lenny Antonelli visited one such house nearing completion in Glasnevin that uses a combination of materials and techniques to aim for highly sustainable results.

The Transition Towns movement has recently come to the fore as a model for sustainable development, with communities around the world signing up to reduce carbon emissions and build resilience in a world where climate change and energy security are emerging as real threats. Leading eco designer Joseph Little of Joseph Little Architects describes how the recent refurbishment and extension of a Dublin house addresses many of the movement’s concerns.  

The introduction of smart metering later this year presents a great opportunity to engage Irish people en masse into substantially reducing their energy consumption, simply by showing them how much electricity they’re consuming, and how much the cost varies at different times of the day. However, as Richard Douthwaite warns, there is a real risk that smart metering may come in a form that benefits the electricity companies and not the end-user.

While the principles of low energy building apply equally for new build and upgrades, the reality is that htting passive levels becomes much trickier when retrofitting. The Passive House Institute have taken this on board and created a retrofit standard that is ambitious but achievable.

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.

Based on past form, the Department of the Environment officials could be forgiven for bracing themselves for a construction industry backlash in response to the proposed changes for Part L of the building regulations which aim to both improve energy efficiency and reduce carbon emissions by 40%, whilst also introducing mandatory renewable energy and air tightness requirements. Jeff Colley outlines why, for reasons of self interest alone it’s very much in the industry’s interests to embrace the new regulations rather than attempt to resist change.

Is it possible to ditch fossil fuels and run a 1970s Irish bungalow on solar energy? Norman McMillan’s renovated A1-rated bungalow in Carlow proves it is.
