Designing a passive house is one thing. Designing a scheme of passive houses to make the most of the views on an extraordinary coastal site is another. And designing that scheme to tie into the local supply chains and architectural vernacular – while ensuring the homes are set up for changing, potentially disengaged occupants – is the stuff of magic.

How do you serve the needs of senior citizens who have fallen on hard times in the Big Apple? In Betances Residence, CookFox Architects have cooked up an extraordinary response, integrating the protective benefits of passive house with beautifully considered, user-tailored design.

The penny has yet to drop for many clients and designers about the risks posed by overheating in an Irish context. With the climate hotting up and building design typically uninformed by feedback on actual performance, is the industry heading for a hot mess, asks Dr Shane Colclough?

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?

Sometimes a building comes along that does almost too much. Passive house stalwarts Kirsty Maguire Architects’ latest opus is an award-winning architectural, engineering, and sustainability feat – which asks questions not just about how we build, but how we live.

Fancy owning an energy positive, timber-based passive house in one of the most desirable locations in England, without the hassle of having to build it yourself? A new three-house development nearing completion in Hertfordshire may be just the ticket.

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?

The proof in the pudding with a notionally low energy building is in the eating. Since moving into their new passive house a little under two years ago, the Murray family’s heating costs have been scarcely believable – in a home that also blitzes the embodied carbon targets in the RIAI 2030 Climate Challenge.

Sometimes reality is stranger than fiction. And sometimes strange but breathtaking fiction subverts reality.

In issue 47 we took a break from our normal approach to Big Picture, with good reason: passive house playing a starring role in an extraordinary US TV show.

Rapidly decarbonising our cold, leaky dwellings is the greatest challenge facing the building industry, one fraught with complexity and risk. Given that the UK faces similar challenges to Ireland – in a similar climate, with similar housing stock – what can we learn from British efforts to meet this challenge? Leading UK green building association the AECB has put forward a proposal that could help to chart a new course through these choppy waters.

As the world edges ever closer to the precipice of runaway climate change, some sustainability terms have moved from relative obscurity towards the mainstream of marketing and public discourse – and none more so than zero carbon. But is zero carbon construction a real prospect, or is it just wishful thinking?

A site with a dilapidated building in Bristol has been transformed into a crucial social space by a husband and wife team of environmentally and socially engaged architects, aided by a polymath sustainability consultant.

If thermal comfort is important for people of all ages, it’s even more so for elderly people, for whom the right living conditions can be a matter of life or death. Passive House Plus visited one award-winning extra care facility in Exeter to learn how the decision to go passive was working out for the residents.

Few architects are tasked with knocking their old family home, but for John Morehead, once this difficult decision was made, it was a chance to create a future-proofed new passive house that embraces its stunning natural surroundings and exhibits remarkable attention to detail.

What does it feel like to suffer the cold, mould and discomfort of a 1960s bungalow, and experience its rebirth as a passive house? The owner of one award-winning project spills the beans.

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.

While the passive house standard has had a lasting impact on the design and construction of new homes in Ireland, progress has been slower in commercial property. With the business world under increasing pressure to take meaningful climate action while providing better working conditions for staff, one new office building in the southeast may be a sign of things to come – and a beacon for a UN-affiliated project.

The new Oxfordshire studio of Charlie Luxton Design, the practice of the well-known TV presenter and architectural designer, is deeply impressive for its exhaustive attention to sustainability across every facet of the project, from energy use and embodied carbon to the reuse of materials and the ecological restoration of the three-and-a-half-acre site. It’s a gorgeous building, too.

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.

What happens when one of Ireland’s most seasoned passive house builders and a renowned design-led architecture practice collaborate? They create a head turning, high density passive house scheme that showcases the aesthetic possibilities of external insulation.

If you were choosing how to build in a bushfire-prone region of Australia, you could be forgiven for skirting over the possibility of packing your walls with straw. Talina Edwards of Envirotecture describes an extraordinary off-grid passive house which uses straw and a range of low embodied carbon building materials to blitz regulatory requirements on fire, while delivering year-round comfort levels that the neighbours can scarcely believe.
