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.

Tom Woolley, Professor of Architecture at Queens University Belfast and Editor of the Green Building Handbook, draws attention to the recent event which demonstrated the potential and importance of sustainable building in Ireland.

The vast majority of Irish buildings are in need of substantial energy upgrade work. Given the difficult economic conditions and low public awareness of the cost, comfort and health benefits of a well-designed energy renovation, the notion of upgrading most Irish buildings is a considerable challenge. However, as Lenny Antonelli explains, new ideas are emerging that could stimulate energy upgrade work on an unprecedented scale.

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

‘Interest in sustainable construction, both from private sector individuals and businesses and from the public sector has grown rapidly in the last couple of years. Unfortunately the ability of the industry to respond to this interest is under developed’ – Tom Woolley.

Conventional wisdom dictates that higher construction costs — for instance to reduce energy consumption and carbon emissions — would either squeeze developers’ profit margins or increase house prices. Tom Dunne, Head of DIT’s School of Real Estate and Construction Economics, reveals how misguided this view could be...

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

For the first time in several years, 2007 will see a budget deficit in Ireland so the question must be asked: where does this leave state aid for sustainable building? Construct Ireland’s Jeff Colley and Jason Walsh propose a new approach to improving the energy efficiency of existing homes that might even fix a few of the difficulties seen in the last eighteen months

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.

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.
