Fears are growing amongst energy rating trainers that Ireland is running out of time to ensure building energy ratings are in place for existing homes at point of sale or rental from January. Jeff Colley spoke to SEI and to leading figures involved in energy rating training to find out more and shed some light on how homes will be assessed.

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 this fifth & final article in the series, Joseph Little compares simulations of several internal insulation options on common wall types, with worrying conclusions.

Ireland has been waiting for a green procurement plan in the public sector for two years. Jason Walsh looks at what the plan should include and why it is needed, now more than ever, and with sustainable building at its core.

In spite of the obvious emergence of technologies and design approaches to reduce the impact of new build, environmental standards remained poor throughout the duration of the housing boom. Now, a unique combination of political will, smart incentives, and a new market of informed and empowered buyers may be about to change that, writes Lenny Antonelli

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

A new development in County Westmeath answers a nagging question about district heating: how to make it financially viable when it services energy efficient buildings. Lenny Antonelli visited a housing estate that combines low energy design with an innovative district heating system and ecological timber frame construction

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

Patrick Daly, co-founder of the RiSE (Research in Sustainable Environments) research unit in the DIT has undertaken an in depth study and critique of the current Irish Part L for energy efficiency in dwellings, comparing it in detail to the UK equivalent. The findings raise challenging questions about the Irish standards and methodology and highlight serious shortcomings in comparison to our UK neighbours, permitting substantially higher levels of CO2 emissions from new homes in Ireland than in the UK.

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.
