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

When residents of Hollywood solemnly and publicly state the need to combat climate change, it is easy to reject as self-righteous, opportunistic bleating. When it’s a resident of Hollywood, County Wicklow, and the environmental statement is in the form of a poroton-block house infused with sustainable features, it provokes an altogether different response, as Lenny Antonelli reveals.

As the new-build sector grinds to a halt a window of opportunity has opened for builders, architects and other construction service providers – refurbishing Ireland’s existing housing stock. Jason Walsh visited an end-terrace house in inner city Dublin to see just how significant the improvements can be.

There’s rather more to designing a sustainable building than specifying low-embodied energy materials and making sure it will require little energy and maintenance in use. Low water demand and the ability to get the nutrients discharged in the sewage back to the land are important too.

As the en masse energy upgrading of Irish homes and other buildings takes-off on an unprecedented scale, there are real dangers that even conscientious clients, professionals and contractors will make decisions that fail to save energy and create unhealthy buildings. Pioneering green architect Joseph Little, draws from the research and experience of his architectural practice & Building Life Consultancy to offer advice that should be heeded before any energy upgrade.

Unless greenhouse gas emissions from land are tackled, any efforts to reduce emissions from buildings may fall short in attempting to stave off the worst consequences of climate change. Richard Douthwaite explains how, with a little ingenuity, techniques can be applied to dramatically reduce land emissions whilst simultaneously providing new raw material streams and energy source

Four years ago the construction industry was focused on building big and fast — but at the same time, a small team was carefully and ecologically retrofitting a terraced Dublin house on a tight budget according to passive house principles.

Box-like, small windows, primary colour renders - there is a common misconception that building to the passive house standard involves sacrificing design freedom for the sake of thermal performance. Not so, argues passive house guru Tomás O’Leary of MosArt and the Irish Passive House Academy, as his selection of architecturally diverse buildings reveals.

Newly elected Green Party Ministers John Gormley & Eamon Ryan talk to Construct Ireland about their vision for a sustainable future.
