A striking new house in County Cork proves that meeting the passive house standard needn’t mean sacrificing good design

With the threats posed by anthropogenic climate change now accepted as a key international issue, efforts to curb carbon dioxide emissions are becoming manifest around the world in spite of – and even as a response to – the global recession. But any such efforts may be in vain if the focus on carbon dioxide distracts from the need to curtail methane emissions, as Richard Douthwaite explains

 
A framework for strategic sustainability is essential if we’re serious about greening the Irish built environment.
According to green architect Pat Barry, we should look no further than The Natural Step.

A new development at Grange Lough, Rosslare, reveals that passive houses can be made Irish – both in terms of what they’re built with, and how they look.

If you’re not assessing the environmental performance of your suppliers and their products, it’s rapidly becoming a case of “caveat emptor”. Many of the world’s biggest companies are now buying green, and the Irish government is about to follow suit. Ignore the issue and you put your company at a competitive disadvantage, argues Brian O’Kennedy, managing director of Clearstream Solutions

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.

Much of the housing built around Dublin over the last forty years has been built of single-leaf nine-inch hollow block construction – which are both notoriously energy inefficient and extremely difficult to insulate effectively without causing damp problems. Lenny Antonelli visited a hollow block house which has been ecologically renovated to protect occupant health whilst shooting to the top of the energy rating scale.

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.

A new extension to the EPA's headquarters in Wexford lives up to the organisation's aim of environmental protection, boasting passive ventilation and lighting, a host of green technologies and a sustainable approach to landscaping.

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.
