Contrary to popular belief, passive house isn’t about maximisation of passive solar gains. It’s about optimisation, balancing free winter heat with avoiding summer overheating. But on a site that seemed hellbent on denying sunlight, every last ray has been stolen to somehow deliver not just a passive house, but a net zero energy home.

An Edinburgh-steeped couple wanted Georgian grandeur in a Cork city infill. Their architect obliged, wrapping double-height spaces and oversized glazing in a climate-responsive envelope that shrugs off Irish winters. Additional reporting: Jeff Colley
Gordon Bunshaft's Banque Lambert has presided over Boulevard Marnix since 1964, a listed modernist landmark facing the King's Palace, its celebrated precast concrete exoskeleton as distinctive today as the day it was built.
The myth that energy-efficient building is a needless luxury has been dealt a significant blow by new research published by the UK’s Passivhaus Trust.
The EU is set to publish plans to reform how electricity and gas are priced – to drive the widespread uptake of heat pumps and cut heating bills by up to 60 per cent.
World-renowned green building writer Lloyd Alter spills the beans on the first ever combined UK and Ireland passive house conference in Belfast.
Life cycle assessments are crucial for sustainable building design, but understanding their inherent limitations is key to making better decisions with imperfect data, writes Dr Lois Hurst.
Made to look easy on TV, Duncan and Anaya decided to give selfbuilding a go and somehow created the most comfortable house they’ve ever lived in – even in the face of extreme heat events.
An award-winning retrofit demonstrates that universal design and ultra-low energy performance are powerful allies, not competing priorities.
With 35,000 homes under their belt, one of the UK and Ireland's most prolific developers has just completed its first passive house scheme - aided by an innovative airtightness approach.
Big Picture - Forrest Passive House in Spotswood achieves certification while maintaining contemporary family functionality through thoughtful material choices and spatial planning.
An architect’s four-year quest to build his family home on a Dublin laneway demonstrates how mass timber can maximize space and character in the tightest urban sites – with award-winning results, and fascinating performance insights.

The Association for Environment Conscious Building (AECB) is recruiting an executive director in what the organisation describes as a rare opportunity to shape the future of sustainable construction in the UK
With an increasing emphasis on the electrification of heat as the electricity grid decarbonises, interest in reducing the embodied carbon of buildings is growing. But does a focus on embodied carbon alone risk giving needlessly energy intensive ways of making buildings a free pass? In the first of a new series of articles, Dr Lois Hurst journeys into understanding embodied and life cycle impacts in construction.
From frozen tea to thermal bliss: energy specialist Esmond Tresidder transformed his leaky 1970s Highland home into one of the highest performing retrofits ever featured in these pages, combining academic knowledge with hands-on retrofit innovation to create a comfortable, healthy family haven with breathtaking views of Ben Nevis, proving that even Scotland’s most challenging climates are no match for passive house principles.
Through passion, patience, and architectural expertise, a 16th century Carmel-ite friar’s cottage in Kinsale, owned by Passive House Plus columnist Dr Marc Ó Riain, has achieved what many thought impossible— an A1 energy rating for a Tudor-era building. But not without challenges.
Ireland's largest passive house development to date, Shanganagh Castle, is proof that with proper planning and collaboration, delivering high density housing doesn’t mean compromising on quality or climate action – without increasing costs or causing delays.
As electricity decarbonises, the case for switching from fossil fuel boilers to efficient use of electricity to heat buildings via heat pumps has become overwhelming. But in markets like the UK where electricity is far more expensive than the European average, and people on low incomes may be chronically underheating poorly insulated homes, could a drive to electrify heating exacerbate energy poverty?
Build Homes Better has secured an updated KIWA Agrément certificate for its Isoquick insulated foundation system, adding a brick support detail that solves a critical structural requirement set by leading warranty providers including the National House Building Council (NHBC).
What do you do when a building type is inefficient, common, hard to treat – and often used to house vulnerable people? Chris Morgan of leading passive house architects John Gilbert Architects tells the story of an extraordinary pilot project that may show the way to solve the stickiest of problems.
In recent years, the drive to reduce the embodied carbon of buildings has led to a resurgent interest in timber and other biobased building materials. But peering into the future, if we are to think not just about carbon but also land, water, and regenerating nature, how might we build to meet our essential needs, and what might we build with?

Mike Eliason, architect, founder of Larch Lab and author of the must read Building for People, reflects on how a series of personal and global crises – from pandemic lockdowns and climate disasters to urban housing challenges – shaped his mission to bring sustainable, community-focused, and climateadaptive neighbourhoods to North America.
Five years ago, a fabric first trailblazer took a dose of his own medicine – and delivered a family home that combines climate action, comfort, cost-effectiveness and resilience in the face of a record-breaking storm.
As global temperatures soar, an Irish organisation is bringing experts together this month for a summit on the future of sustainable construction.
It’s a radical idea: that to negate the environmental damage of construction, we don’t just need to build sustainably, we need to build less. However, most architects and building designers earn a living by doing exactly the opposite: by building stuff. So how can the design practice be reinvented for a world in which we need to do more with much, much less?
What do you get when a clinician couple decide to build their dream family home? In the skilled hands of leading Scottish architects Paper Igloo, you get a forensically detailed, highly ecological, cosy home that wraps up low embodied carbon and passive house into a beautiful design.
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.
