In the hands of the right architect, meeting the passive house standard needn’t involve compromising on design. Construct Ireland visited a recently certified passive house which shows that a seamless low energy architecture is possible

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.

High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.

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

Can a supermarket be green? Tesco's new store in Tramore, County Waterford suggests that, at least in terms of the building it’s housed in, the sky’s the limit. Jason Walsh visited a building which meets passive house standards and demonstrates impressive attention to sustainability throughout its design.

Newly inaugurated RIAI president Paul Keogh selects four diverse UK projects that integrate sustainability without compromising on design

SEAI recently proposed a series of changes to Deap — the software tool used to calculate BERs — including a reduction in its primary energy factor. But while this will benefit electrically-powered heating devices, some in the industry still feel systems such as heat pumps are disadvantaged by Deap and the BER system

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.

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.
