An energy conscious renovation and extension in south Dublin breathes new life into a typical semi detached home — the house is now wrapped with external insulation and boasts breathable and ecological materials too.

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.

The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.

Energy efficiency is about more than just U-values – the building envelope must be airtight and virtually cold bridge free. Construct Ireland visited a single-leaf concrete house nearing completion in Moate which combines an excellent envelope with wind, solar and a range of green measures, with the aim of reducing energy and carbon figures to zero in the home’s BER score.

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.

In an ideal world every occupied building in Ireland would be energy upgraded to the highest standard, tapping into numerous benefits for the building occupant, the construction industry and society as a whole. Construct Ireland is calling for the introduction of pay as you save, a repayment model which offers the potential of making significant energy upgrade investments achievable in the vast majority of Irish buildings, as Jeff Colley reveals.

Everyone knows that the cheapest way of doing something can turn out to be very expensive in the end. The decision to make Ireland ’s electricity system so reliant on gas is about to bear this principle out. By Richard Douthwaite.

Up till now, the activities of semi-state energy companies like Bord na Móna, ESB & Bord Gais have not won the favour of environmentalists. Richard Douthwaite explains how that situation is destined to rapidly change, and exclusively reveals details of the ambitious new green direction being adopted by Bord na Móna.

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.
