The Welsh government has issued a new standard for social housing that requires an embodied carbon assessment, favours timber-based offsite construction, and bans fossil fuel boilers.

At COP26, the United Nations Economic Commission for Europe (UNECE) recognised the UK’s Sustainable Development Foundation (SDF), along with South West College in Northern Ireland and the Construction Scotland Innovation Centre, as international centres of excellence for high performance buildings.

Most people think of cold, cramped and poor-quality buildings when they think of student accommodation, but two new passive house residences at King’s College, Cambridge are rewriting the rulebook, with their focus on occupant comfort, architectural quality, and an enlightened, long-term view of construction costs.

An intriguing new passive house in Dundee takes the traditional ‘box’ form associated with the standard and turns it on its head, using a series of pitched roofs and different claddings to make it feel more like a traditional city terrace than a single dwelling – built with a heavy emphasis on carbon sequestering materials.

Coventry University research has found that 40 per cent of primary school classrooms examined in a study did not have an adequate ventilation rate to combat the spread of Covid-19.

Complete with butterfly roofed extension, this fabric first renovation has turned a cold and uninspiring 1970s bungalow into a cosy A-rated modern home, with some clever design touches helping to open the house up to wide-angle views and dramatic coastal light.

Sometimes it takes the constraints of a challenging site to bring out the best possible design, and that was certainly the case for this Limerick City passive house, where the project team managed to deliver a unique, curving passive house in response to a tricky urban plot.

In recent years, as energy efficiency targets for new buildings have tightened, attention has turned to cutting the embodied carbon of buildings by switching from materials like concrete and steel to lower carbon alternatives like timber. But if we are serious about solving the ecological emergency as well as stabilising the climate, we must look even further than embodied carbon, and think more deeply about the core values we apply to materials and buildings, and the manner in which we use them.

The UK and Ireland’s oil heating industry says it has taken a “major step forward” in the use of biofuels in domestic oil boilers, with early tests concluding that hydrotreated vegetable oil (HVO) works in virtually all existing oil boilers.

Ahead of the Built Environment Summit (28-29 October) and COP26 (1-12 November), the Royal Institute of British Architects (RIBA) and Architects Declare have published a report demonstrating the critical role the sector must play in reducing greenhouse gas emissions.

The Passive House Institute celebrated the low energy standard’s 30th birthday at the 25th International Passive House Conference in September. Around seven hundred participants registered for the conference, which mostly took place online due to Covid.

A new analysis of the exposure of London households to indoor pollutants highlights “systematic inequalities” in exposure, overwhelmingly driven by factors beyond the control of those people worst affected.

The winners of the international Passive House Award will be announced on Friday 10 September as part of the 25th International Passive House Conference, which is fully available online. Tickets to the conference are still available.

While the Irish government is delivering CO2 monitors to schools to help prevent the spread of Covid-19, and some European regions have mandated the use of such monitors in all buildings open to the public, the UK has yet to introduce such measures and has removed the requirement for mask-wearing in schools.

The redevelopment of Agar Grove by Camden Council in London was the winner of the large project award at this year’s UK Passivhaus Awards, which were held on 30 June.

South West College’s new Erne Campus building in Enniskillen, Co Fermanagh, is the world’s largest, and the first educational building, to be certified to the passive house premium standard, the Passive House Institute has confirmed.

This all-wood passive-certified home in the village of Kippen was built directly by its architect owners, who not only achieved the passive house standard but did so with an ecological approach that sought to use building materials ultra-efficiently and make it easy to deconstruct and recycle the building at the end of its life.

A new passive house on Galway Bay beautifully blends vernacular design with touches of Arts & Crafts while still appearing thoroughly contemporary, but under its neat exterior is the thinking of an architectural practice striving to reduce the environmental impact of its buildings, inspired by the Architects Declare pledge.

Angle House in north London is a wonderful example of sustainable urban housing: modest in scale and built on a run-down site in the heart of north London, it boasts a passive approach to energy efficiency and some beautiful design touches.

Proper ventilation has been recognised as an important quality for school buildings at least since the Victorian era. But, in the current pandemic, have we lost sight of the role of ventilation?

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.

Duncan Smith reflects on the social and architectural significance of Glasgow's tenement flats, and their potential place in a zero carbon future, as the city prepares to host COP 26. 

Leading insulation manufacturer Xtratherm has announced the signing of an agreement in principle to purchase Ballytherm’s operations in Ireland and the UK.

On June 8, 2021 Passive House Plus, in association with Farrat, chaired a hugely informative roundtable on thermal breaks. If you missed it, the video can now be viewed online.

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.
