Ireland's new central bank hits nZEB & BREEAM outstanding eco rating

Rising from the shell of the stalled riverside headquarters of Anglo Irish Bank, Ireland’s financial regulator could be accused of insensitivity for choosing as its new home a site that became a toxic symbol of the banking crisis, but the building is not without virtue: it comfortably surpasses the proposed nearly zero energy building standard while achieving the onerous Breeam ‘Outstanding’ rating for sustainability.

The dazzling Dalkey home with a hidden agenda

Even in the era of climate change, there still appears to be something of a split in the world of architects between those who prioritise sustainability, energy efficiency and occupant health, and those who put design and aesthetics first. So it’s refreshing to find that the designer of this contemporary Dublin home put so much attention on insulation, airtightness and indoor air quality — as well as good looks.

Life in an air-heated passive house - Five years on

Homeowner Brendan Murphy started self-building his Cork passive house way back in 2010, long before the standard was trendy, and even chose to completely forgo a water-based heating system. So what did he learn from the experience — and how has the house been performing since?

This cellulose-filled timber frame house in the Suffolk countryside combines a rustic timber aesthetic with a simple contemporary form to rest lightly on the land.

A1 passive house overcomes tight Cork City site

Designing a dwelling to take advantage of the sun’s free heat is a big part of what makes a passive house passive. So how do you meet the low energy standard when your narrow site faces away from the sun and is overshadowed by neighbouring houses and trees, while simultaneously hitting an A1 building energy rating – and with a stunning, architecturally expressive design?

South London scheme delivers better health for residents

A sensitive development of social housing in Lambeth combines three new passive houses with six low energy flats delicately constructed inside an old Victorian terrace — and with the emphasis on good indoor air quality, residents are already reporting improvements in health & well-being since moving from their old accommodation.

Timber & Straw passive house is a world first

Built with a timber frame insulated with straw-bale, and featuring an extensive suite of ecological and recycled materials, this stunning North Yorkshire home also produces more energy than it consumes, making it the first straw-bale building in the world to reach the brand new ‘passive house plus’ standard.

DIY Cork builder hits passive & NZEB with first self-build

Despite having no construction experience, self-builder Eamonn Fleming decided he could build a new family home more cheaply — and with better attention to detail — if he did it himself. And even though he didn’t set out to build a passive house, he managed to meet the standard while doing almost all of the work in conjunction with his father, while exceeding the targets of Ireland’s nearly zero energy building definition.

Norfolk straw-bale cottage aims for passive

Passive house design is often seen as belonging to the world of hi-tech construction — perhaps unfairly, seeing as it emphasises a good building fabric over bolt-on technologies. Straw-bale construction, meanwhile, is usually regarded as the preserve of only the most committed, do-it-yourself eco-builders. To some these two approaches appear to be chalk and cheese, but in fact they are inherently compatible, and more and more projects are now combining the maths-centred approach of passive house with the extensive use of natural materials. In the first of a series of case studies on passive straw-bale dwellings, Lenny Antonelli spoke to architect Fran Bradshaw of Anne Thorne Architects, who designed and built a straw-bale home for herself in Hickling, Norfolk two years ago — and aimed to meet the passive house standard while doing so, with only a single infrared electric panel as the building’s sole active heat source.

Simple and stunning Highlands passive house merges old and new

While embracing traditional farmstead design made it trickier for this new build home in the Scottish Highlands to meet the coveted passive house standard, mixing modern standards of super-insulation with vernacular farmhouse architecture ultimately led to the creation of a very special home for proprietors Jeanette and Jon Fenwick — one that picked up a coveted UK Passivhaus Award in 2016.

UK's largest passive building opens to 2,400 students and staff

Completed early this year, the new Centre for Medicine at the University of Leicester is by far the largest single building in the UK to meet the passive house standard — and not surprisingly, its design and construction posed tough new challenges for how to meet the rigorous low energy standard on such a large, complicated building.
