Our role: Passivhaus consultancy Mechanical services design Co-heating test Post occupancy monitoring & occupant support   The project: 20 social houses in rural Cornwall completed in 2011.  Passivhaus was chosen because there was no gas on the site, and the housing association had very poor experience with heat pumps.   Our focus: This was our first significant Passivhaus scheme, we provided consultancy from concept through to completion on the building fabric.    We undertook the mechanical services design, which relied heavily on electricity for heating and hot water (plus solar thermal).  Using electricity to heat meant achieving Passivhaus was critical, and we focused particularly on reducing losses from the hot water system.  We were particularly keen to see how the buildings actually performed so undertook a co-heating test on two of the dwellings.  This was one of the first such tests on a Passivhaus development.   In addition, for the whole site we took hourly data on room temperatures, humidity in addition to energy use for heating, hot water and small power.  We also carried out regular interviews with the occupants.  The results have been very interesting and fed through to our work in numerous ways from lobbying PHI regarding internal heat gains to improvements in our ventilation commissioning.    The team: Client: Aster Group Architect:Mitchell Architects  Certification by Co-create...

Our role: Passivhaus Certification   The project: 18 mixed tenure dwellings in London completed in 2012 (plus a further 12 that were close to meeting Passivhaus)   Our focus: The team was relatively inexperienced so in addition to certification we provided support on all aspects, from how to apply PHPP to a larger site to what to look for on site.  Once completed we also helped with fault finding and remedial work to ensure the occupants got the best out of the project.   The team: Client:Octavia Housing Architect: Cartwright Pickard                  ...

Princedale Road

2011 – This project, part of the Technology Strategy Board’s (TSB) Retrofit for the Future competition, sets a milestone for low energy refurbishments in the UK. Not only does this project meet the Passivhaus Institut’s EnerPHit refurbishment standard (25 kWh/m2yr, 1.0 achr@50Pa), it meets the newbuild Passivhaus standard as well (15 kWh/m2yr, 0.6 ach@50Pa). What is remarkable about this is that it is done within the confines of local planning policy – in a conservation area. This is done by the use of substantial amounts of internal insulation (200 PU foam) and triple glazing sash window look-alikes. The key to the airtightness, an order of magnitude better than most UK newbuilds, lies in the way that the void between each floor has been treated. Normally this area is a nightmare for airtightness, and what is impressive about this refurbishment is the way that Phillip Proffit, of Ryder Strategies, designed the insulation package. Instead of wrapping membrane around joist buried in the external wall, he designed a steel beam (pictured) to pick up all the joist ends, shortening them so that he had a continuous three storey high void to place his insulation and OSB air barrier in, uninterrupted by the floor zones. Other innovations include Heat Recovery Ventilation with a labyrinth running under the basement floor to preheat the external air, and the aforementioned triple glazed windows. Brilliant – well done all the team who were involved!
