This new development of 28 units brings affordable passive housing to the Isle of Wight, bolstering the island’s bold eco ambitions while embracing a traditional seaside aesthetic.

This inspiring rural passive house, designed by architect Graham Bizley and his wife Emily, is first and foremost a striking piece of contemporary architecture that enhances its scenic location 

This issue’s collection of inspiring international passive houses includes a striking Black Forest family home, the world’s first ‘passive house premium’ building, a deeply ecological Canadian house, and a New York tower that’s set to be the world’s tallest passive house.

The latest versions of PHPP and designPH are intended to make passive house design both easier and more accurate than ever before — and to plan for a future powered by renewable energy. Jan Steiger of the Passive House Institute explains the latest features of both software packages.

The Energiesprong initiative is planning to deliver drastic energy upgrades to over 100,000 homes in the Netherlands using a wildly ambitious approach to retrofitting the country’s building stock. Now the organisation has moved to the UK, where it is hoping to undertake its first projects next year.

As the climates gets warmer, overheating in buildings is likely to get worse — particularly given the modern architectural preference for huge expanses of unshaded glass. But what really causes overheating, is it really worse in low energy buildings, how do passive houses fare, and what can be done to prevent it?

For decades now, European countries have been regulating the amount of energy new buildings can consume for heating and electricity. But as these standards get ever tighter, is time to start controlling the embodied energy and wider environmental impact of building materials — and what’s the best way to do it?

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.

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. 

The head teachers of an East London school put their interest in sustainable building into practice by adding a new passive house extension — and the results already seem to be paying off for pupils.

Huge expanses of unshaded glass are usually a taboo for passive house designers, but with his clients insistent on maximising their wide-angle coastal panorama, this project’s architect found clever ways to integrate the passive house approach with wrapping the house’s ground floor in glass.

This house on the coast of County Waterford is built from an insulated concrete formwork shell that delivers an inherently warm and airtight construction, and easily exceeds passive house targets.

Three years ago quantity surveyor Ross Cremin set out from scratch with the goal of self-building a passive house on a site in rural County Longford. Here he tells the story of his project and offers advice for others thinking of building their own passive house.

This issue’s selection includes a Chinese apartment block, Finnish social housing, an ambitious New York retrofit, and a German passive house district

The Tory government's decision to scrap the proposed zero carbon standard for new dwellings might appear to be a kick in the teeth for green building — but could the move present an opportunity for a better  standard to step in?

The upgrade of two social housing blocks in Manchester to the Enerphit standard demonstrates how deep energy retrofit can play a part in turning old, run-down estates into vibrant, comfortable, low energy communities.

This ambitious and complicated project — a partial upgrade, partial rebuild of an old detached property in south Dublin — is on course to achieve the onerous Enerphit standard for retrofit.

This affordable housing scheme in Exeter not only embraces a suite of healthy and natural materials, but it has vindicated the local council’s embrace of the passive house standard, with many of the units requiring no additional heating whatsoever.

In April 2010, Geoff and Kate Tunstall moved into their pioneering house at Denby Dale. It was one of the UK’s first passive house projects, and the first to be built with a traditional British cavity wall system. Five years later, how are the Tunstalls finding life in a passive house?

This summer, work was completed on the Enterprise Centre at the University of East Anglia, which might just be the most sustainable large building ever constructed in Britain.

Despite some setbacks, this passive house in Roscommon managed to meet the passive house standard for fairly standard costs — all while emphasising natural materials like untreated timber, cellulose and sheep’s wool.

This striking new-build passive house combines a traditional farmhouse form with ultra-low energy performance and a spectacular location – using two different forms of masonry construction

This issue’s international selection features an embassy in Indonesia, an educational building in South Korea, an experimental solar-powered house in France, and social housing in Philadelphia.

As previously revealed in Passive House Plus, the evidence appears to indicate that natural ventilation systems don’t adequately ventilate our homes. But does mechanical ventilation perform any better?
