Homeowner Brendan Murphy started self-building his Cork passive house way back in 2010, long before the standard was trendy, and even chose to completely forgo a water-based heating system. So what did he learn from the experience — and how has the house been performing since?
This ambitious experimental retrofit of a Victorian barn high in the hills of West Yorkshire has turned a cavernous, draughty space into a comfortable low energy period home — and cut its heating bills by over 80%.
A new development of passive housing on the outskirts of Norwich shows how to combine energy efficiency, ecology and affordability on one exemplary site — and why the city continues to be an unlikely leader in pushing passive house construction in the UK.
This cellulose-filled timber frame house in the Suffolk countryside combines a rustic timber aesthetic with a simple contemporary form to rest lightly on the land.
In the first in a new series of technical articles on some of the key technologies in sustainable building, John Hearne makes the case for wrapping buildings in an external insulation layer, and describes some of the main issues to watch out for.
The first social housing scheme of any kind to top Ireland’s BER scale, this project is a timely reminder that in the midst of a national housing emergency, it is possible to tackle climate change and blitz the forthcoming nearly zero energy building targets, while housing the most vulnerable in society in healthy, fuel poverty-proof homes predicted to incur zero heating cost.
If the reduce, reuse, recycle mantra has a built embodiment, it’s arguably the recently completed Rediscovery Centre in Ballymun, Dublin – a 1960s boiler house for a much maligned early district heating system that’s been transformed into a sustainability education centre, and that makes use of a remarkably large palette of green materials and sustainable technologies.
Designing a dwelling to take advantage of the sun’s free heat is a big part of what makes a passive house passive. So how do you meet the low energy standard when your narrow site faces away from the sun and is overshadowed by neighbouring houses and trees, while simultaneously hitting an A1 building energy rating – and with a stunning, architecturally expressive design?
An oversized passive house may be no more sustainable than a correctly sized house built to a more modest spec. In the latest instalment of her journey to build a passive family home, Nessa Duggan finds that visiting some real passive houses may force a change in approach regarding size and complexity, with potentially significant cost benefits.
A sensitive development of social housing in Lambeth combines three new passive houses with six low energy flats delicately constructed inside an old Victorian terrace — and with the emphasis on good indoor air quality, residents are already reporting improvements in health & well-being since moving from their old accommodation.
With an intricate design based on the concept of two pitched-roof sections that overlap, this eye-catching timberframed Sussex home proves you can meet the passive house standard with just about any shape.
Built with a timber frame insulated with straw-bale, and featuring an extensive suite of ecological and recycled materials, this stunning North Yorkshire home also produces more energy than it consumes, making it the first straw-bale building in the world to reach the brand new ‘passive house plus’ standard.
In the sixth report on her journey to self-build a passive house, Nessa Duggan struggles to reconcile glazing functionality and thermal performance, takes conflicting advice on heating and ventilation, and reaches some decisions on joinery.
Designed around an existing timber chalet, this striking contemporary house managed to go passive on a budget for one lucky family of six, all while inadvertently blitzing Ireland’s forthcoming nearly zero energy building standard.
This large family home in south Dublin proves that big homes don’t need to be cold and draughty, comfortably beating Ireland’s planned nearly zero energy building standard for 2021 — even though it was finished in 2015.
Investigations may eventually confirm the specifics of how the fire at the West London tower block spread so catastrophically on the night of 14 June, but the government and construction industry faces much deeper questions about whether a culture of deregulation, cost-cutting and buck-passing turned what should have been a small, inconsequential fire into a national tragedy.
A brand new passive-certified nursery at the University of Aberdeen provides the children of staff and students with a bright, warm and healthy space for learning and playing.
This is what you get when one of Ireland’s most experienced low energy builders creates a home for his own family, with help from one of the country’s foremost ecological architects — a modern and elegant passive house that pays detailed attention to sustainability at every turn.
At a time when the industry’s under increasing pressure to deliver cost-effective, robust, low energy homes at breakneck speed, one new west Dublin project is leading the way – while picking off sustainability targets for fun.
After a litany of dangerous and high profile building failures in Ireland, many in the country’s building industry looked longingly across the Irish Sea and held up the UK as an example of how to do building control properly. But following a series of embarrassing defects with UK construction projects, it’s clear the British system is far from perfect. So is either of these building control systems properly equipped to deliver safe, healthy and well-constructed buildings?
In the fifth instalment of her column on designing and building a passive house for her family, Nessa Duggan talks about the importance of getting good advice — on everything from airtight sliding doors down to your choice of timber flooring.
In the second instalment of this column, architect and DIT lecturer Simon McGuinness outlines the key priorities for the industry to learn in order to deliver successful ultra low energy buildings in 2017 and beyond.
The gradual decarbonisation of our electricity grids — as renewable energy is phased in, while coal and peat are phased out — coupled with the proliferation of new buildings with very limited heat demand, has some experts asking if heating our homes and offices directly with electricity is starting to make sense again. So is it time to bring back the dreaded storage heater?
