G&S win funding from TSB for energy performance evaluation

Gale & Snowden Architects Ltd are pleased to announce that we have been successful in winning funding from the Technology Strategy Board (TSB) under the energy performance evaluation funding.

The intensive assessment over the next 18 months will be for the Passivhaus flats at Knights Place which were commissioned and are owned by Exeter City Council. The project was designed by Gale & Snowden Architects and completed in summer 2011. The in depth study will include:
  • energy monitoring
  • dynamic U-value and heat flux monitoring of building materials
  • air quality monitoring
  • temperature, humidity and CO2 monitoring
  • thermal comfort assessment for both winter warmth and summer overheating
  • renewable energy systems performance monitoring
  • tenant questionnaire

Through this monitoring, we will be able to assess how a Passivhaus scheme performs in operation. Part of the monitoring will be to compare a Passivhaus building with MVHR to a super-insulated, naturally ventilated dwelling.
 
The funding was won as part of a competition run by the TSB. The results of the monitoring will be published on our website in due course.

Opening ceremony for new extension to social club at Woolsery Sports and Community Hall

The ongoing success of the community building was celebrated on 30th September with an opening ceremony for the new extension designed by Gale & Snowden Architects.  The original building was designed 10 years ago and remains one of the most environmentally aware public buildings in the UK.  The quality of the design was recognised in 2003 when the building was awarded a special Civic Trust Award for 'Vital Villages'.

David and Sam Gale were present at the extension opening ceremony and thanks were given by the community for Gale & Snowden's work and their charitable contribution to the project.

More information about Woolsery Sports and Community Hall can be found on our website.

Insulating a Cob Cottage - 1

Jason our mechanical and energy engineer has recently been taking some time off from work to renovate and insulate his own cob cottage.  Having already plastered internally using traditional methods and lime based plasters it was now time to apply what was learnt to the external facade.   In its existing condition the cottage had cement render which needed to be replaced due to cracking and movement.   This presented an ideal opportunity to also apply some form of external wall insulation system.  Having researched various different ways of insulating cob walls ranging from hemp products to EPS systems to wood fibres Jason deciding on using a lime based insulating render system containing perlites.  A render system called Unilit 20 with a  thermal conductivity of 0.066 W/m.K.   Whilst  not as good as some modern insulants this is still a significant improvement over applying nothing.   A balance had to be found between maintaining the aesthetics of the cottage and cob, vapour permeability and cost.    In addition the render system  has extraction qualities which promotes the drying out of the humidity and moisture in the walls which in turn ensures the walls stay warmer for longer.

Prior to the work taking place SPAB (Society for Protection of Ancient Buildings) decided to use the cottage as part of a research project they were conducting.  This  research project, which is part funded by the Dartmoor National Park Authority's Sustainable Development Fund is concerned with investigating the thermal performance of traditionally built walls and what can be done to improve them.  


The SPAB Building Performance Survey, prior to the works taking place, looked at:
  • Fabric heat loss through the U-value measurement of wall elements both in the form of in-situ and calculated U-values.
  • Air infiltration through air permeability testing and thermographic survey.
  • Moisture, room and wall moisture including wall surface and interstitial moisture behaviour.
  • Indoor air conditions and comfort levels via the measurement of CO2.
  • Interior temperature and relative humidity.
Once the insulating measures have been carried out SPAB will return this winter to carry out the tests again.  In addition to the external insulating render it is intended to dig out the ground floors and insulate them, increase the roof insulation and make the cottage more air tight.

G&S obtain funding through TSB Design for Future Climate: Adapting Buildings Round 2

Gale & Snowden are pleased to announce that we have been successful in winning significant funding for two clients' projects from the Technology Strategy Board (TSB) - Design for Future Climate: Adapting Buildings Round 2 competition. The projects are a new public swimming pool facility and a new office complex, both to be designed to Passivhaus standards. The funding is to allow the practice to investigate solutions to deal with future climate change by employing our skills in building physics and low environmental impact, passive design.

The award of the funding comes after the practice was successful last year in the Round 1 funding from the TSB for investigating and designing in climate change adaption for an Extra Care Facility in Exeter, Devon. This Round 1 work will be completed in October 2011 and the results will be made available shortly afterwards.

G&S Passivhaus flats shortlisted for multiple awards at 2011 LABC South West Building Excellence Awards.

Gale & Snowden's Passivhaus scheme at Rowan House for Exeter City Council has been shortlisted for three awards at the 2011 LABC South West Building Excellence Awards: Best Social Housing Development; Best Technical Development and Best Sustainable Development.

3 Passivhaus flats at Rowan House, Sivell Place, Exeter

The 3 flats at Rowan House, Sivell Place, Exeter are among the first social housing accommodation in the UK to be built using the Passivhaus method for an apartment development.

When the client, Exeter City Council, was offered a funding opportunity by the HCA to develop council housing in Exeter, it was decided to use this chance to provide exemplary, affordable housing, built to the highest standard of sustainable construction.

To meet the stringent Passivhaus standard it was required to achieve exceptional levels of air tightness with the air permeability target as low as 0.3 cbm/sqm/h. This, together with high levels of insulation, high performance windows and doors, thermal bridge free detailing and the use of a more than 90% efficient mechanical ventilation system has reduced the overall heating demand to a minimum so that a traditional heating system was not required.

Achieving the Passivhaus standard was only possible through the combined effort of the design team developing the air tightness strategy and detailing, the site management team and builders for implementing this strategy and finally the client for their commitment and passion to deliver an outstanding, exemplary housing scheme. Purely through passive design elements Rowan House will use approximately 90% less heating energy when compared to a standard UK building (if built to current Building Regulation requirements). In other words Rowan House could be heated by the equivalent of 1.5 litre of heating oil, i.e.15 kWh of thermal energy per sqm per year, or 60p per sqm per year (based on a price for heating oil of 40p a litre), making it truly affordable for its future tenants without compromising on comfort or indoor air quality.

This year the LABC SW Building Excellence Award winners will be announced at a black tie gala dinner on Friday 24th June 2011.  David, Lawrence and Tomas from G&S will be attending.

Excellent feedback follows TSB presentation


Extra Care for Exeter.  Gale & Snowden Architects

"I really enjoyed the presentation on this project. They are confident that they can provide a safe thermal environment for vulnerable older occupants to 2050 using a passive design. My favourite part is the knowledge that older people in the UK aren't used to passive homes and so they are building in an alert system to prompt occupants to close their windows when the temperature is higher outside than inside.

Another lovely aspect of this project is that they took the opportunity to totally redesign the care home to have bedrooms facing north and the living rooms facing south and overlooking communal gardens to give a sense of other people being around. It's not just a design to avoid overheating above 25 degrees, but also designed to be a more pleasant place to live."
