Forgive the 80s hip hop house reference in the headline, but the volume of the walls in this volumetric modular school building in Birr was literally pumped up – with recycled newspaper insulation. Built to passive house principles, it’s a story of one Roscommon manufacturer reimagining the role that offsite methods can play in the delivery of highly sustainable permanent accommodation for schools – while delivering exceptionally low embodied carbon results.

While tokenistic or poorly conceived attempts at supporting the decarbonisation and greening of buildings still abound in the finance sector, there are signs of structural changes on the horizon - changes designed to unlock widespread change. But do those changes go far enough?

As governments come under increasing pressure to make real and significant reductions in energy use and carbon emissions while tackling energy poverty, interest in passive house has never been higher. But short of expecting regulators to commit to certified passive house, is there a way of adopting the key principles that make passive house work?

In September Cairn Homes lit the fuse on a passive house explosion, publishing a position paper on passive house and announcing the construction of nearly 1,800 apartments to the standard. But what’s behind the company’s bold move?

Last year Irish banking behemoth AIB launched discounted development finance for homes certified to the Irish Green Building Council’s rating system, the Home Performance Index. But what was behind the move, how is it being received and does this indicate the finance industry is getting serious about green homes?

How do you solve a problem like decarbonising social housing, and do so rapidly, en masse, in a manner that lifts vulnerable people out of fuel poverty while delivering warm, healthy homes? River Clyde Homes may be about to pull off the seemingly impossible.

The ever-tightening ambitions to integrate sustainability throughout Ireland’s new and existing buildings won’t be realised unless we can find smart, flexible ways to upskill the industry. Lis O’Brien of Technological University of the Shannon (TUS) explains how Digital Academy for Sustainable Built Environment (DASBE) has it cracked.

Sometimes a building comes along that asks challenging questions. Chris Croly, building services engineering director of BDP, describes one such example – a building designed to tackle the specific energy profile of offices, while trialling an innovative, dynamically controlled approach to adaptive comfort.

Actor Ed Begley Junior is one of America’s best-known and longest-standing environmental activists. Fresh from lighting up our screens in the final season of Better Call Saul, Begley spoke to Passive House Plus about the roots of his activism, and what drives him on in the face of such adversity.

The pioneering Cannock Mill development in Colchester is just the second cohousing project in the UK to achieve passive house certification, making it a leader not just in terms of its thermal performance, but in demonstrating the vital role shared living can play in both building vibrant communities, and in mitigating the climate crisis.

Since Erne Campus opened its doors in September, students of South West College in Enniskillen can now experience one of the world’s most environmentally advanced higher education buildings, and the largest building in the world so far certified to the passive house premium standard, in recognition of both its highly efficient building fabric and the large amount of solar energy it generates.

A new housing scheme designed by Coady Architects in Wicklow has achieved the highest green home certification – while suggesting that the convictions of one practice on a single project can help to transform the industry.

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.

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.

Where basements are present in low energy buildings, they can prove a weak spot without particular care and attention, as Passive House Association of Ireland board member John Morehead of Wain Morehead Architects Ltd explains.

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.

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.

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.

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.
