Landowners & Cement Producers Gain, Homebuyers & Taxpayers Suffer. By Richard Douthwaite

Thanks to the ESCo model, one school in Donegal has gone green, seen its heating bills reduced by 15% yet has not had to outlay one cent in capital expenditure. John Hearne investigates an emerging trend that is bringing low carbon energy into another realm.

Designing a low energy building when you've got unlimited space is one thing – but what if you need to make your walls thin to maximise space on a small site in an architectural conservation area? Lenny Antonelli visited a new St Vincent De Paul sheltered housing project that fit a lot of sustainable features on to a small plot in Dublin's north inner city.

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.

Achieving building regulations compliance and a good energy rating is one thing. Delivering a genuinely low energy building is quite another. A new scheme by one of Ireland’s most decorated developers may help show the market a way forward.

Can a supermarket be green? Tesco's new store in Tramore, County Waterford suggests that, at least in terms of the building it’s housed in, the sky’s the limit. Jason Walsh visited a building which meets passive house standards and demonstrates impressive attention to sustainability throughout its design.

The rapidly growing public interest in sustainable building is finally starting to impact on property developers. Bill Quigley of Nutech Consultants describes an innovative 200 house development currently on site in Co. Cork where forward-thinking developers J & W Leahy Brothers have decided that the market is ready for low energy, low CO2 buildings.

Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.

Jason Walsh spoke to David Smith of O'Mahony Pike Architects about the practice's uniquely-designed show apartments for this year's Myhome.ie Spring House and Garden exhibition.

It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.
