The notion that curbing CO2 emissions would damage economic growth has been used as an excuse from developed countries such as the USA not to switch from fossil fuels to renewable energy. However, as Richard Douthwaite reveals, the people of Austrian town Güssing are discovering firsthand that this couldn’t be further from the truth.

The rapid emergence of sustainable building in Ireland has been heavily influenced by the techniques of early-adopters extending from Scandinavia, to Canada, to Germany and Austria. John Hearne visited a recently completed timber home in Galway which uses Austrian know-how to couple air-tightness, high levels of insulation and healthy materials with a sustainable approach to heating and ventilation

Buildings that are designed or refurbished to use little energy all too often fail to deliver the expected performance, if the building occupants aren’t able to use the building as intended. John Hearne reveals the crucial role that user-friendly heating controls play in ensuring that a theoretically low energy building delivers the expected results.

For a building to truly be considered a passive house a vast range of criteria need to be met, as Niels Bjergstrom, founder of Zero-Carbon Solutions Ltd reveals.

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

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

A log bungalow in rural Meath has been extended and given a total energy upgrade – and wood is at the heart of the renovation, with a timber frame extension and external insulation system along with a fresh log finish.
