With oil prices nearing record highs, forward thinking developers who’ve taken the initiative to incorporate green aspects into their projects are showing a buoyancy that starkly contradicts the downturn, as John Hearne reveals.

In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.

Ernst Posthuma of Solarcon sheds light on a demonstration project in west Cork that combines passive and active solar gains to remarkable effect.

Construct Ireland’s John Hearne discovers a low energy, low carbon house being built in Galway which is achieving sustainable results whilst not jarring with aesthetic conventions.

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.

The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.

The worl­d has learned the hard way that our political leaders lacked the judgement and resolve to identify and address the problems which led to the recession. Richard Douthwaite argues that a similarly flawed judgement is evident in the assumption that the economy will recover, and advises on how to prepare for a future of global economic contraction.

The Carroll’s cigarette factory in Dundalk has been reborn as an avant garde exemplar of wind energy storage and an ingenious approach to integrated heating, ventilation and cooling, as sustainable design expert Chris Croly of BDP explains.

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.
