Lark Rise is an elegant new passive house in rural Buckinghamshire designed by bere:architects, but it is more than ‘just’ a passive house. Because it produces and stores so much of its own energy through on-site solar power, it is a certified passive house ‘plus’, and in this article, its architect Justin Bere explains how dwellings like this can play a key role in decarbonising our economies and societies in the coming decades.
With a decade of experience designing primary schools to the passive house standard under their belt, Architype have now designed the UK’s first passive secondary school — and all of the evidence suggests there is no better way to ensure a healthy, comfortable environment that is supremely conducive to learning.
Facing the challenge of how to bring a Victorian home with damp old brick walls up to a modern low energy standard, architect Brendan O’Connor deployed an innovative solution: build entirely new and superinsulated timber frame walls within the old structure.
A stunning new passive house in Cork breaks the conventions of passive house form with a design that manages to be both dramatic yet discreet at the same time, inspired by a US project to contort itself beautifully into its steeply sloping site.
This issue features a passive house ‘plus’ certified three-storey office building in Strasbourg, France.
As awareness of the urgency of the climate crisis grows, efforts to kickstart en masse deep energy efficiency interventions are gathering apace. But poorly conceived low energy building efforts can lead to unintended consequences including overheating – a risk that’s bound to grow as the world warms up. Phi Architecture co-founder Claire Jamieson details the risks and offers some solutions on how to create low energy buildings that are comfortable in summer and winter.
Climate breakdown and global ecological crises mean that our efforts to make buildings sustainable must go far beyond operational energy use – including number crunching and drastically reducing environmental impacts of building materials. John Cradden reports on progress in the uptake of the building blocks of life cycle analysis of buildings: Environmental Product Declarations.
Air source heat pumps are rapidly becoming one of the dominant technologies in sustainable building, but how well do they perform in real world conditions? Can they be part of the solution to retrofitting homes, given the challenges in making existing homes suitable for low energy heating? A rare monitoring study on a pioneering retrofit scheme offers encouraging signs.
Radon is one of the most dangerous indoor air pollutants, yet there is little research on how it is affected by different forms of construction and ventilation. A new study, however, suggests that homes built to the passive house standard are significantly less at risk of radon build-up.
Despite the challenges of getting planning permission within a national park, a new passive house on a hillside in the South Downs managed to woo the planners with a sympathetic, discerning design inspired by a surprising source — two dilapidated old chicken sheds.
A beautifully detailed and rustic new passive house in the north of Scotland was built with a unique off-site construction system using local timber, and was created by a design-and-build firm that aims to put sustainability at the heart of everything it does.
It sounds like an impossibility: a high density, architectural, zero energy home on the tightest of back garden sites, adaptable to the needs of everyone from empty nesters to a family of six without opening a toolbox. But sometimes a project comes along that redefines what is possible.
This issue features an intriguing new passive house apartment building in north-west Spain.
How we heat our homes has a direct impact on the quality of air that we breathe. This impacts on our health. The impact is both local and national. Burning solid fuel – in an open fireplace or stove – generates fine particle pollution which affects the air in our own home and in the local neighbourhood. There are choices and actions we can take that will reduce this pollution.
In the early stages of the Covid-19 crisis, there was little official recognition that airborne transmission was a risk. Has that view changed, and what role will building ventilation play when winter approaches?
The UN’s Scott Foster says deep retrofit of our building stock, and a sustainable built environment, should be at the heart of our recovery from the Covid-19 pandemic.
With governments across Europe looking for ways to jump start their economies following the early impact of Covid-19, attention is increasingly turning to deep retrofit. But while there is strong evidence that deep retrofit could play a major role, the devil will be in the detail – and the challenge of dramatically upscaling a nascent industry shouldn’t be underestimated.
Built mostly with clay blocks and sited above the sandy shores of Seaton, on the Devon coast, this new development of eight high-end apartments not only meets the passive house ‘plus’ standard — meaning it pairs the requisite ultra-low energy fabric with a substantial amount of renewable energy generation — but it also boasts serious attention to the use of ecological and healthy material.
This issue features the passive house ‘plus’ certified headquarters of Métropole Rouen Normandie, located on the banks of the Seine in Rouen, France, and designed by Jacques Ferrier Architecture.
This inspiring project may be exactly what the deep retrofit sector needs: an example of how to turn a bog standard, cold suburban home of little architectural merit into a climate champion delivering outstanding levels of energy performance, comfort and health, all while transforming the building architecturally.
A rundown 1970s scheme of one-bedroom, single storey social housing units in Ballyshannon, Co Donegal, has been transformed into a pioneering development of cosy, A-rated, NZEB-busting homes. The pioneering project – the first completed under Ireland’s deep retrofit pilot scheme – also breathed new life into an unloved green area and is expected to help fuel a regeneration project in the town.
Even though its stunning views lay directly northward, simple design, good detailing and lots of insulation have turned this 1960s semi on the edge of Dublin Bay into a warm and light-filled low energy home.
Cement is responsible for up to 8% of global carbon emissions, and in this guide, sustainable design expert Jay Stuart looks at ways to minimise its environmental impact through good design, and at some of the alternative, lower carbon cement and concrete products on the market.
When it comes to air pollution, we tend to worry most about things like traffic fumes and solid fuel burning — or when it comes to indoor air, condensation, damp and mould. But one of the biggest threats in the air we breathe comes from something we are exposed to almost every day, but rarely think about: cooking. John Hearne reports on the evidence for how cooking affects indoor air quality, and what we can do about it.
