Passivhaus active

Jonathon Porritt

Jonathon Porritt, Founder Director of Forum for the Future, has called upon the UK construction industry to urgently embrace the German low energy standard Passivhaus as part of efforts to meet the 2016 Zero Carbon target. Speaking in the Foreword to Green Building Store’s new technical film ‘Passivhaus low energy building in the UK’ launched on Tuesday 12th October 2010,  Jonathon Porritt stressed the urgency with which the construction industry needs to adopt low energy construction and praised Green Building Store’s efforts to combine traditional UK cavity wall construction with the Passivhaus standard in its Denby Dale Passivhaus project.

In his Foreword to the film, Jonathon Porritt says :

“I think people in the UK are just waking up to how far behind we are on really energy efficient housing, in comparison with other European countries. And the great thing is this Government has now confimed the Zero Carbon housing target for 2016 so we’re going to have to be doing a huge amount to catch up. We’re going to have to see an unprecedented wave of innovation around construction technques and design. For me it’s really important that what’s been going on elsewhere particularly in Germany with Passivhaus is now brought in as part of that innovation cycle in the UK.. And I think we know that the kind of design features that underpin the Passivhaus idea will be invaluable to builders and to communities here in the UK”.

The ‘Passivhaus low energy building in the UK’ film is freely available to view at Green Building Store’s website www.greenbuildingstore.co.uk from 12/10/10. The 60+ minute film aimed at building professionals covers all stages of construction of the Denby Dale Passivhaus – the UK’s first Passivhaus to be built using traditional British cavity wall construction methods.

To get cavity wall to perform to Passivhaus standard, the Green Building Store team needed to develop many original design details. The film includes much of the technical detailing for the project, including floor and foundations, first floor, roof, window openings, mechanical ventilation with heat recovery systems and much more. The film sets out to offer the UK construction industry a template for building ultra low energy Passivhaus buildings using construction methods and materials familiar to UK builders and designers. It can also offer detailing for radically improving the energy efficiency and airtightness of cavity wall construction, regardless of whether the project is aiming for the Passivhaus standard.

Filmed over 12 months of construction, the technical film contains on-site footage and technical diagrams and graphics, as well as interviews with the clients and Green Building Store Directors. Green Building Store has also made a 10 minute documentary ‘Future Passiv’ (presented by TV environmentalist Penney Poyzer) which makes the case for Passivhaus low energy building in the UK to a wider audience. The technical film and documentary will be available to freely view from Green Building Store’s website www.greenbuildingstore.co.uk from 12/10/10. A free technical briefing on the Denby Dale Passivhaus project to accompany the film is also available as a 40 page pdf for building professionals registering at: www.greenbuildingstore.co.uk/denbydalehouse

Denby Dale Passivhaus
The Denby Dale Passivhaus project in West Yorkshire is one of the first certified Passivhaus homes in the UK and is the first to be built in the British vernacular style, using a cavity wall construction. The house will require minimal heating and will use 90% less energy for space heating than the UK average. Built to a tight budget of £141K, the 118m2 three-bed detached house aims to be an exemplar of how Passivhaus construction can be achieved inexpensively by a small, skilled construction team. The project was led and managed by Green Building Company (Green Building Store’s construction division).

Key features
