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. 

The UK's greenest ever retrofit - 6 years on

This pioneering upgrade project, completed in 2009, turned a Victorian redbrick in Birmingham into one of the UK’s greenest homes. Along with a much wider ecological agenda, the house employed fabric first principles
of insulation and airtightness, and met passive house design targets at a time when the standard was still in its infancy in the UK.

Cork bungalow upgrade phased over 12 years

It’s taken Mick Kiernan more than 10 years to upgrade his Cork bungalow, and it’s still not finished. But along the way he discovered the passive house standard and let its principles guide his way towards a warm, airtight and healthy home. 

UK's first Enerphit, six years on

Six years after it was completed, Passive House Plus takes a look at a pioneering low energy upgrade that went on to become the UK’s first certified Enerphit project, to find out how it has performed — and what lessons have been learned.

Fabric first retrofit rejuvenates Dublin social housing

Built in the 1970s, Rochestown House was a cramped, cold and damp social housing block in Sallynoggin, Co Dublin that has now been completely transformed, thanks to a deep energy retrofit inspired by passive house principles.

How to rescue a 1970s bungalow

A passive retrofit in Co Meath offers a template that could be applied across much of the Irish housing stock: a long, dark, 1970s bungalow was transformed into a bright modern home that’s now warm and comfortable.

Passive retrofit emerges from ashes of 80s bungalow

If you’ve ever wanted to take a passive house for a road test, one holiday letting on the coast of west Cork may be too good an opportunity to turn down. The aptly named Sea Spray – an as yet uncertified Enerphit upgraded bungalow – is a bona fide triumph in the face of adversity.

How to save social housing blocks

Britain and Ireland’s post-war social housing blocks are seen as ugly and uncomfortable, and suffer from high energy bills, damp and mould. But three ambitious renovation projects show the answer doesn’t always lie in demolition.

Deep retrofit brings Victorian home up to Enerphit

There was a time when insulating an historic property meant treading lightly on its building fabric. But today, guided by building physics, passive house designers continue to push the boundaries of retrofit by bringing old homes up to modern standards of super-insulation. This project is the third such deep retrofit to an historic London property by Green Tomato Energy.

London upgrade future proofs historic building

The general consensus is that it’s not appropriate to upgrade historic buildings to avant garde energy efficiency levels, creating a sense that conservation of the natural and built environments may be mutually exclusive concerns. Not so, argue Arboreal Architecture’s Harry Paticas and passive house engineer Alan Clarke in an updated version of a paper presented at the 2014 International Passive House Conference, about a highly experimental upgrade to a London townhouse that may point to a sustainable solution.
