Cork retrofit blitzes new build NZEB standard

The retrofit and extension of a run-down semi in Cork shows just how radically a typical Irish home can be transformed with a skilful retrofit — and why, if your budget is limited, upgrading the building fabric should be your first priority.

Cheshire semi gets passive retrofit for £60k

Vet Chris Copeman was so meticulous about the deep retrofit of his home near the village of Frodsham that he decided to train as a passive house consultant and project manage the build himself. The result? A certified passive house created on a surprisingly low budget.

The deepest greenest retrofit ever?

With obsessive attention to preserving and restoring the original fabric of these two Victorian townhouses, and a commitment to shunning petrochemicals and using only natural materials, could this be the most wildly ambitious and sustainable passive retrofit ever undertaken in the UK?

Holy Trinity

Situated in a stunning location in the west of Ireland, between Galway Bay and the limestone hills of the Burren, this project provided a complex challenge in three parts: deep retrofit an old cottage into a yoga studio, reinvigorate its original extension, and build a new barrel-roofed passive-grade extension — then make it all work together as one unified home and workspace.

Historic London house gets near passive transformation

The default answer when you want to do pretty much anything to a listed building is ‘no’. The default assumption if you want to achieve the Enerphit standard for retrofit is ‘tackle everything’. So how on earth do you retrofit a listed building to within a whisker of the Enerphit standard — with the blessing of the conservation officer?

Granite-hewn Victorian home upgraded to PHI low energy standard

Built in 1850, this home in Dartmoor national park would have relied on local timber supplies for heating until the advent of widely-available central heating. One passive house-flavoured retrofit later, it’s back to its wood-burning roots – only this time with much less wood use, and much higher comfort.

From derelict shop to tiny low energy home

In 2014, one couple decided to give up life in a van and convert an old newsagents in Shrewsbury into a very small low energy home, using the principles of the passive house standard as their guide. So how did it work out, and what is life really like in such a small home?

World class passive social housing

Simultaneously tackling fuel poverty and climate change requires drastic action on deep retrofitting the existing housing stock – and fast. Dún Laoghaire-Rathdown’s deep retrofit and renovation of Rochestown House may be Ireland’s most significant retrofit to date – a fact reflected in the project picking up the sustainability award at the 2017 Irish Architecture Awards.

Dublin boiler house reborn as green building exemplar

If the reduce, reuse, recycle mantra has a built embodiment, it’s arguably the recently completed Rediscovery Centre in Ballymun, Dublin – a 1960s boiler house for a much maligned early district heating system that’s been transformed into a sustainability education centre, and that makes use of a remarkably large palette of green materials and sustainable technologies.

18th century ruin becomes stylish low-energy home

Homeowners Anne and Patrick Jordan’s ambitious upgrade and extension project in County Kildare took the shell of an 18th century farmhouse and transformed it into an elegant family home with a striking-yet-sensitive modern extension — all while embracing a healthy and fabric-first approach to retrofit combined with clever heating system design that has brought them from a G to an A3 rating.

Solihull upgrade trials revolutionary retrofit approach

An exciting and innovative new deep retrofit project in Solihull has drastically cut the energy consumption of a small block of flats by smoothly and efficiently wrapping the entire structure in both insulation and ventilation ducting, delivering huge energy savings and minimal disturbance to the residents.

Deep retrofit transforms big, complex South Dublin home

At first glance, this sprawling house in Blackrock would appear to be a nightmare candidate for a deep energy upgrade — large and sprawling, and with a mix of structures built at different times and with different materials. But guided by the passive house standard, the team behind it managed to turn a G-rated energy guzzler into a healthy and very-low energy family home – complete with an A rating.

Welsh school fuses passive & eco material innovation

This new award-winning two-building extension to a primary school in the south of Wales delivers healthy, ultra low energy school buildings – one of which is passive house certified – while pushing the boundaries of timber engineering. 

Fermanagh schoolhouse reborn as passive family home

The abandoned husk of a 1960s school building sounds a very long way from a comfortable, ultra low energy family home. Thanks to a remarkable upgrade effort – influenced by reading Passive House Plus – one Fermanagh family are reaping the rewards of one such transformation.
