KORE Retrofit, a leading provider of sustainable retrofit solutions in Ireland, is pleased to announce the appointment of Dr Barry Mc Carron as its new managing director. Mc Carron brings extensive experience in sustainable development, building energy performance, and project management to this pivotal role.

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.

Home buyers seeking sustainable luxury and energy income in a sought-after part of England have a rare opportunity with a newly launched passive house scheme in St Albans.

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.

In issue 38 of Passive House Plus we published an in-depth assessment comparing the build specs including five wall types to a typical Irish house. To enable the industry to fairly compare a broader range of build options, we now expand that analysis with the addition of four timber frame wall types and two insulated concrete formwork systems

Can a low energy building be truly sustainable if it doesn’t fully consider its occupants needs? The latest offering from one of Scotland’s leading green designers uses passive house knowhow to signal the way to pragmatic, modest, occupant-centric architecture.

We take a look at Pepper Tree Passive House, a small secondary dwelling attached to a young family’s home in the Australian Illawarra region.

Sometimes a building comes along that asks challenging questions. Chris Croly, building services engineering director of BDP, describes one such example – a building designed to tackle the specific energy profile of offices, while trialling an innovative, dynamically controlled approach to adaptive comfort.

A passive house, by its nature, requires a much smaller amount of energy than a typical home, and when its heating demand is met by electricity, and you cover it in solar PV panels, you can start to see the potential for a whole new generation of passive homes that are semi-independent of the electricity grid. This is the case for Carrstone House in Bedfordshire, which generates so much solar energy it had to be registered as a power station.

A new development in County Wicklow demonstrates how typical housing estates might be turned into electricity microgrids through solar power and battery storage, with residents buying and selling renewable energy from each other, helping to insulate them from price spikes and outages.

In trickier housing markets, the instincts of house builders have often tended towards building to the worst legal standards required – or worse. One award-winning new project in Belfast’s suburbs is showing that it doesn’t have to be this way – and that developers can thrive by pitching homes designed to ensure comfort and low bills at increasingly energy-conscious consumers.

Issue 43 featured an off-grid prototype house in British Columbia, designed and constructed to demonstrate an innovative approach to future building.

What do you get if you cross a quantum physicist, a forensic accountant, a merchant, an engineer and a software-whizz-kid architect? A terrible punchline presumably. But as Jeff Colley discovered on a trip to Sussex, you get something not to be laughed at: a collaborative approach that may be about to unlock a scalable, highly sustainable, circular economy-proof, flat pack build approach.

The potential of the passive house standard to change the world isn’t restricted to tackling climate change – it’s about social justice too.

Actor Ed Begley Junior is one of America’s best-known and longest-standing environmental activists. Fresh from lighting up our screens in the final season of Better Call Saul, Begley spoke to Passive House Plus about the roots of his activism, and what drives him on in the face of such adversity.
