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.

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

With money leaving local economies across Ireland to service debt and significant drops in local authority revenues, towns such as Dundalk, Ennis and Kilkenny are investigating the possibility of bringing in electronic currencies to keep money circulating locally, as Richard Douthwaite reveals.
