Nottingham passive house enters Solar Decathlon

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

A cursory browse through Dublin Civic Trusts website and one is all too quickly reminded of the constant threat to our Architectural heritage

Chris Croly from BDP outlines the low energy and renewable energy strategies used in University College Cork’s new Environmental Research Institute, a test bed for the design and performance of sustainable buildings, which is ideally suited to housing the 200+ environmental projects carried out by its researchers.

Located in Oldtown, a hard to find country town in County Dublin, is a stunning new one-off house that not only manages to bring open-plan living to rural life, but also meets the onerous passive house standards using low impact materials. Jason Walsh visited the site as the house neared completion to find out more, an opportunity that Construct Ireland couldn’t pass up

Due to the ill-considered productivity of the house building industry towards the tail end of the economic boom, Ireland is now saddled with hundreds of thousands of vacant homes in various states of completion. Structural engineer Sadhbh Ní Hógáin, currently writing her thesis for a masters architectural degree in advanced environmental and energy studies at the Centre for Alternative Technology, looks at the options Ireland has to address the problem.

Germany has a reputation for high quality craftsmanship, an attention to detail and a positive attitude to sustainable and healthy housing. Jason Walsh visited a new German-built house in County Dublin to see if the expertise can be exported.

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.

Every eurozone government has debt problems and is cutting its spending, Richard Douthwaite says. Defaults and a prolonged depression are inevitable unless countries inject money into their economies in an unconventional way. A prosperous low-carbon economy would be the result

John Hearne spoke to a number of independent energy experts to develop an impartial view of the main sustainable heating options.
