How to Earn £1300 a Year from a Zero Carbon Passivhaus
Fenestration Calculations
Larch House, our first Welsh Passivhaus Social Housing prototype, is officially certified by the Passivhaus Institute and has also been designed to achieve Zero Carbon Code 6 of the Code for Sustainable Homes. This is a 3 bed passivhaus designed to minimize Annual Heat Demand (below 15kW/m2/yr). Much of the winter warmth in this house is derived from solar gains, but Ebbw Vale is 1000ft up in the top of a valley, with cold and misty winters. To keep winter heat inside, the insulation levels are very high and because of the relative lack of winter sun compared to a lowland site, the windows are unusually large to maximize the solar gains from a bright overcast winter sky (55% of south elevation). This is the traditional design strategy for a passivhaus, resulting in great comfort, tiny energy bills, and bright and airy interior spaces. However for social housing, we needed to find a way to overcome the costs associated with large windows and retractable blinds, so we made subtle but crucial changes to the way we designed the second passivhaus, Lime House, currently under construction.

A new mini-community of zero and near zero carbon homes on the site of the old steel works at Ebbw Vale look set to not only stimulate the development a low carbon built environment in Wales but also to kick-start a ‘green’ economy in the country.
The Welsh Future Homes project, launched today by Jane Davidson AM, Minister for Environment, Sustainability and Housing, is a unique development of three affordable houses and a visitor centre. One of the homes has been designed to meet Level 6 of the Code for Sustainable Homes, making it a zero carbon home - the first to be achieved in Wales.
Each of the buildings are constructed from a range of locally sourced materials that demonstrate high sustainability credentials and low energy costs of as little as £50 per annum.

Following the huge success of the North London conference in February, which was fully booked in a week with a waiting list of more than 100 people, a much bigger, national conference will take place this Autumn (again in London) with a much wider outreach. The steering group is putting together an exciting programme which includes a low-cost exhibition of carefully selected, high quality suppliers.
Watch this space for more information coming soon.

Our Welsh Passivhaus social housing prototype today achieved what is probably the best result so far for a UK pressurised air test for an above-ground, detached house. As predicted, the second airtest which was carried out today on our 3 bed social housing passivhaus prototype (after completion of M&E installation including services penetrations) achieved an even better result than the first test. On decompression at 50 pascals the result was 0.17 air changes per hour, but on average of 50pa decompression and compression, 0.197 air changes per hour was the final result as measured and calculated by Paul Jennings, probably the UK’s most respected air testing specialist.

Fund raising is now complete. The tenders came in on budget. One of the UK’s first certified Passivhaus retrofits starts on site on May 17th. The building is predicted to make 94% energy savings compared to the existing building, while at the same time greatly increasing the usable floor space of the building. When the centre re-opens it will be re-orientated southwards to a new community garden.

On Monday the timber frame contractors of our Welsh Passivhaus prototype social housing managed a fantastic first air test result of 0.29 air changes per hour under 50 pascals air pressure! This is one of the best air test results carried out by a UK contractor so far; more than twice as good as the minimum standard required for a Passivhaus, 34 times better than UK Building Regulations, and right up there with the best current German construction standards.
It’s a really great show of what can be achieved by the UK construction industry where there is a keen and motivated and diligent contractor teamed with diligent architects providing a carefully thought out and thoroughly explained airtightness rationale. Continue Reading »

The Camden passivhaus home is about knowledge transfer from Austria and Germany and the Welsh Passivhaus project is about trying to apply this knowledge to social housing prototypes. We are also working on a terraced Welsh Passivhaus home to save more money and energy than detached houses.
Where there is political will, such as in Wales, we believe it is possible to achieve 90% energy savings in houses now. This is in spite of the Welsh heads of valley location having Winter conditions as unfavourable as an Austrian mountainside. This is because, whilst the winter outdoor temperatures in Wales are warmer than Austria, there is a lot less winter sun on a Welsh hill than on an Austrian mountain.
We are trying to show that the UK can and should be making massive savings on all new buildings NOW. The less-developed world is understandably becoming very frustrated with the lack of action from the developed world. Two days ago, the chief negotiator for India at the Copenhagen and Mexico climate change conferences described the overall achievements so far of the UK, America and Australia as “pathetic” and he is absolutely right about this.

What was planned as a small Camden and Islington Passivhaus conference on February 3rd for local architects and council employees, quickly became an over-subscribed event and a major UK Passivhaus conference. Refer to the following link for more details: www.cuttingthecarbon.co.uk/news/15/101

These are the first prototypes for passivhaus homes at Ebbw Vale in Wales, to be on show at the Eisteddfod in July this year. 700 homes are planned for the site over the next few years. Wales is going zero carbon on all new homes from next year (2011) and it is possible that they will define zero carbon as based on the Passivhaus standard of energy efficiency. This is a definition of zero carbon that is 3 times more ambitious in terms of specific heat requirements than the English definition of zero carbon to be applied to new homes in England in 5 years time.

Camden Passivhaus, Camden, London
(due to be completed March 2010)
The primary objective of this project is to achieve a comfortable home for a young family, whilst minimising energy consumption. This house has been designed to use less than 13kWh/m2/a for heating (a typical new home in the UK is likely to consume nearer 100kWh/m2/a)
The project is a 120m2 single family house split over two floors, with two wild flower meadow roofs and a south facing garden. Continue Reading »

Councillor Alexis Rowell of Camden Council, the Liberal Democrat ‘Eco Councillor’ and very active chair of the Camden Sustainability Task Force has organized what will arguably be the first dedicated Passivhaus conference in the UK (The AECB could also arguably claim this). The decision to organize the conference came after a period of broad but intensive research by Alexis and the Camden Council Sustainability Taskforce on cutting carbon emissions in UK buildings. This research was carried out in the UK (inviting a wide range of experts to present to the Sustainability committee) and abroad (research visits) by Alexis and other Liberal Democrat councilors.
One of the most convincing research visits included a trip to Frankfurt to meet the leader of the passivhaus schools programme there, Axel Bretzke, and to visit the successful Riedberg School, now famous throughout Europe for its proven success in cutting energy consumption to amazingly low levels. Axel explained that the Frankfurt school was developed after energy and air quality monitoring of traditionally designed schools. Apart from the high energy demand of contemporary traditionally designed schools, they found, in practice, appalling winter air quality in schools that relied on only natural ventilation. By combining natural (summer) and active (winter) heat recovery ventilation, the Riedberg passivhaus school is now famous throughout Europe for achieving extremely low heat energy and electrical demand, whilst at the same time achieving extremely good summer and winter air quality.

The Welsh Assembly, advised by Nick Tune of BRE (Wales), is leading the UK in its drive towards the most efficient, low energy designs possible for new housing.
These are similar first steps to those of the small, self-contained Vorarlberg region in Austria. In the early 1980’s, when in the UK we were squandering our oil reserves without making any plans for renewable energy generation or energy efficiency, as if there was no tomorrow, the government of Vorarlberg developed a plan for self-sufficiency in food and energy. Vorarlberg is now prosperous and the community is well housed, well educated, well fed and relatively happy. Continue Reading »

Energy Data Monitoring: results from a Passivhaus using no heat energy whatsoever, compared with results from a London Terraced House using occasional heating
Passivhaus and the Muse
The Muse, my home and also my office, was started on site in 2002 before I knew about Passivhaus techniques emerging in Germany; but together with Max Fordham we discovered an approach, unique in the UK at that time, that is almost identical to the Passivhaus approach. Wolfgang Feist, the founder of the Passivhaus Institute, has visited the Muse and announced at the AECB conference this year that he is keen to provide certification subject to satisfactory energy monitoring and careful checking of our PHPP analysis. So until our various other Passivhaus projects are complete, energy and temperature monitoring of my own house provides the best possible comparison of energy use with traditional housing in the UK.

Wolfgang Feist, founder of the Passivhaus Institute, teaches at AECB national conference, June 2009 and gives masterclasses at bere:architects
Wolfgang Feist came to the UK to provide a series of lectures over two days at this years AECB national conference at Oxford Brookes University. As a physicist and a university lecturer, his talks are always clearly presented and illustrated by graphs based on robust data derived from the monitoring of hundreds of completed projects around Europe and further afield. He explained the fundamental principles of Passivhaus design over a number of packed sessions. Even for those who were already familiar with these advanced techniques, there was much to benefit from hearing them direct from Wolfgang and to be able to hear the answers to questions from the audience.
After the conference, Wolfgang came to London where he spent a long day with invited guests at my home, the Muse. Continue Reading »

Wednesday July 1st 10:00 - 14:00 – Early booking essential
We have aimed this CPD at those people who want a detailed and practical introduction to Passivhaus design, but who are not ready to do a full PHPP course (see AECB website for info about a full course). We aim to give attendees a good understanding of what it is like to design using the German Passivhaus Planning Package (PHPP).
We understand that the event may sell out early but we have offered to do another at a later date if RIBA London keeps a waiting list.

Planning permission was granted on January 15th for our Camden Passivhaus. The structure is being pre-fabricated in Austria and the Austrians will fit the windows, the electrics, the plumbing and all the finishes to achieve the highest quality of workmanship in the shortest time possible.
Knowledge Transfer and Training for Passivhais Skills
Cllr Alexis Rowell of Camden Council (www.ecocouncillor.org.uk) will organize a team of councillors, planning and sustainability officers to monitor progress of the construction and learn from the techniques brought over from Austria in order to help Camden achieve his vision of incorporating Passivhaus requirements into the Camden’s Local Development Framework. A number of learning workshops are planned during the process of the build, in order to help UK partners and policy makers to understand how to attain the standards that we need in the UK to achieve the most energy efficient house design concept in the world today.
