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.

As interest in sustainable building continues to escalate, Construct Ireland is increasingly unearthing buildings that betray an ambition to break new ground under a plethora of green criteria. John Hearne visited one such house in County Louth, and found a project driven by passive house and BER scale-topping ambitions combined with on-site energy and water supply strategies and a commitment to the use of green materials

Intended as a landmark not only architecturally, Áras Chill Dara sets an example for large scale sustainable building, as Construct Ireland’s Jason Walsh found out.

In an ideal world every occupied building in Ireland would be energy upgraded to the highest standard, tapping into numerous benefits for the building occupant, the construction industry and society as a whole. Construct Ireland is calling for the introduction of pay as you save, a repayment model which offers the potential of making significant energy upgrade investments achievable in the vast majority of Irish buildings, as Jeff Colley reveals.

The government recently announced a fund of e100 million for energy upgrading Irish houses in 2009, to be divided equally between low income and middle income earners. Focusing on the latter, Jason Walsh looks at the details of the Home Energy Saving scheme and speaks to key figures in the industry to get their views on the ingredients needed to make the scheme a success

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

Upgrading and extending a semi-detached house on a tight site in Limerick required ingenuity from architect Patti O’Neill.

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.
