The Deerings, a large new certified passive house in the Hertfordshire village of Harpenden, is the stunning result of meticulous attention to design, energy efficiency and ecological materials by its architects, builders and a homeowner so taken by the experience that it led to an investment in an innovative passive house start-up.
Glavloc has recently completed a 129 square metre three-bedroom house in Carrickmines, Dublin, using the company’s innovative rapid-build construction system, which combines off site manufacturing and on-site assembly
Built in 1850, this home in Dartmoor national park would have relied on local timber supplies for heating until the advent of widely-available central heating. One passive house-flavoured retrofit later, it’s back to its wood-burning roots – only this time with much less wood use, and much higher comfort.
In 2014, one couple decided to give up life in a van and convert an old newsagents in Shrewsbury into a very small low energy home, using the principles of the passive house standard as their guide. So how did it work out, and what is life really like in such a small home?
In his second column on visionary eco-buildings of the 20th century, Dr Marc Ó Riain looks at the Dover Sun House, which used a pioneering salt solution to capture and store solar energy
Two spectacular low energy social housing units looking out over Ulva Ferry’s breath-taking surroundings prove to be a superb response to local problems of fuel poverty and lack of affordable family housing.
SMET Building Products, which supplies a wide range of products for low energy and fabric-first construction, picked up the award for best small business at the Greater Newry Business Awards, organised by Newry Chamber of Commerce & Trade, on 28 September at the town’s Canal Hotel.
Leading low energy ventilation supplier Sustainable Homes Scotland has advised anyone carrying out a deep retrofit — or building a small low energy dwelling — to consider the benefits of a new generation of decentralised mechanical ventilation with heat recovery (MVHR) systems.
This house on the coast of County Waterford is built from an insulated concrete formwork shell that delivers an inherently warm and airtight construction, and easily exceeds passive house targets.
Twelve units in Great Yarmouth deliver low energy bills and comfort for new tenants using patented timber frame system.
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.
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.
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.

Late last summer, work finished on architect Paul McNally’s latest super low energy project: a three-storey building in Tipperary that has just become Ireland’s first certified passive house pharmacy.
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?
Saint-Gobain has launched its ‘Multi Comfort’ building concept at Ecobuild in London. Click here to see a short video outlining the idea, which is based on passive house principles.
Advantage Austria is to host a CPD-oriented presentation and networking event on passive house and low carbon building in Edinburgh on 2 October.
It's not too hard to remember a time when 'passive house' was a rare, hallowed term. Of course it is still the zenith of low energy building. But there was a time only a few years ago, at our predecessor magazine Construct Ireland, when the possibility of featuring a certified passive house only came along every couple of issues.
My blog post last week on 'passive house vs passivhaus' generated a fair bit of debate, so I thought it'd be nice to take a look at some of the reaction it provoked. The vast majority of those who responded disagreed with my stance, and this magazine's stance, expressing preference for the German 'passivhaus'.
How do you make an old building liveable on Ireland’s wind ravaged Atlantic coast? The answer lies in the envelope, with airtightness, super insulation and the eradication of cold bridges
People planning to build a new home could save themselves thousands of
euro each year by developing a passive house, according to the Passive
House Association of Ireland (PHAI), a new low energy design initiative
comprising passive house designers and contractors.
Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.
Creating the right comfort in buildings for elderly people involves ensuring a warm internal environment, which typically results in high energy consumption. John Hearne visited the new Castle Gardens Retirement Village as it approached completion and found a project that combines complimentary low energy technologies, materials and design to deliver high levels of comfort whilst also keeping running costs, energy consumption and carbon emissions low
It is hoped that the lessons learned from the construction and monitoring of these buildings will assist in reducing the energy usage of future school designs.
As policy makers start to set mandatory low energy and renewable energy requirements as conditions of planning, the ability of the construction industry to find sound low-cost ways of achieving the new standards is becoming a key factor. John Corless speaks to leading sustainable building consultant Jay Stuart of Delap & Waller EcoCo and Paul Gilmartin of Ecobead to discover an approach with enormous potential for en-masse usage.
