Red brick Surrey home becomes an unintentional passive house

The team behind this Surrey home intended to use it as a test-bed for passive house design and construction, without necessarily expecting to achieve certification. But as the house neared completion, they realised that they were within touching distance of the coveted low energy standard.

Passive research centre acts as living showcase for green tech

A new research centre in Northern Ireland could stake a claim as being one of the greenest buildings on these islands. Not only is it passive, it boasts a whole suite of ecological features, and aims to be at the cutting edge in the research and development of new sustainable and renewable technologies.

The builder's view - why passive house doesn't cost extra

With this passive house in Co Kildare, father-and-son building team Pat and Paul Doran prove that meeting the strict low energy standard can be done for even less than a ‘normal’ build – to the tune of a €20,000 reduction in build costs compared to the Department of the Environment’s suggested compliance approach.

International selection - issue 11

This issue’s international selection features a developer-built passive house in Philadelphia, a big new research centre in Frankfurt, a sleek family home in Vienna, and a new low-energy factory in Canada where passive timber buildings will be prefabricated.

UK's first Enerphit, six years on

Six years after it was completed, Passive House Plus takes a look at a pioneering low energy upgrade that went on to become the UK’s first certified Enerphit project, to find out how it has performed — and what lessons have been learned.

Fabric first retrofit rejuvenates Dublin social housing

Built in the 1970s, Rochestown House was a cramped, cold and damp social housing block in Sallynoggin, Co Dublin that has now been completely transformed, thanks to a deep energy retrofit inspired by passive house principles.

Essex house nears passive against the odds

When Mike Jacob of Trunk Low Energy Building started planning to build this unique Essex home, it seemed likely to run way over budget, and still fail to meet the passive house standard. But rethinking key details and making tough compromises got the house within touching distance of passive, while slashing costs.

Hereford archive chooses passive preservation

Safeguarding historic documents and other artefacts requires stable building conditions. Until now this was usually achieved with the expensive and energy-hogging use of heating and cooling equipment, but a new
approach by Herefordshire Council used the passive house approach to conserve energy, money — and the county’s precious historical archives.

Smart Dublin passive house shows tiny heating bills

Building this stylish south Dublin passive house, which recently picked up a Made in Germany energy efficiency award, demanded a steep learning curve, not least when it came to airtightness — but despite the struggles, it ultimately gave its owners their dream low energy home.

International selection - issue 10

This issue’s international selection of passive and low energy building includes two homes built for retirement —one in Austria, one in New Mexico — a striking house in a Romanian forest, and an out-of-this-world passive-certified dome in tropical south-west China.

Will building boom see low energy failures?

Low energy building isn’t complicated, but it’s easy to get wrong. Since Irish house builders downed tools en masse when the last boom ended, energy efficiency standards for new homes have seen unprecedented rises of 40% in 2008 and 60% in 2011, shooting far ahead of the UK. But with signs of a new boom emerging, can the industry get to grips with this brave new world of insulation, airtightness and thermal bridging and deliver healthy low-energy homes — or are damp and mould set to become the norm in new build?

The new proposed passive house classes explained

The Passive House Institute’s announcement of new classes of passive house certification – including renewable energy generation – at this year’s International Passive House Conference caused something of a stir. Dr Benjamin Krick, the institute’s head of component certification sheds some light on the new classes and explains the rationale behind proposals which may set up passive house for a fabric first approach to near – and sub – zero energy building.

How to rescue a 1970s bungalow

A passive retrofit in Co Meath offers a template that could be applied across much of the Irish housing stock: a long, dark, 1970s bungalow was transformed into a bright modern home that’s now warm and comfortable.
