In the second installment of a new feature on international green buildings, Lenny Antonelli takes a look at four innovative, sustainable and striking buildings from around the world.

Hugh Dorrian, member of the Main Committee of the recently launched Building Limes Forum Ireland reveals lime is regaining ground as a key material not only in conservation projects, but in new build.

Sustainable building at its best is about much more than just energy and carbon emissions, and involves considering location, form, orientation and the use of healthy, environmentally friendly materials. Mike Haslam of trail-blazing ecological architects Solearth describes a family home which scores highly on every front

With the building of a new house in Greystones, County Wicklow, Ireland has become only the third country to feature the work of Frank Lloyd Wright. Jason Walsh visited the site to see if Wright's designs might just represent the kind of thinking required in today's energy-conscious buildings.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects

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.

After a long struggle to build their home, Karen and Steve Ward finally got their wish — an energy efficient, timber frame house that boasts a palette of healthy and ecological materials and a fully renewable heating system.

Sustainable architect Simon McGuinness describes a project in Dublin which is set to surpass the onerous standard using structural insulated panels.

It is not alone as an artist and historical author of distinction that Peter Pearson is noted.  His role as a conservationist in the last three decades has had a tangible effect in protecting Ireland’s built heritage, and raising consciousness of the value and importance of conservation work

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.
