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                  ...

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!

Our role Passivhaus consultancy – Refurbishment Mechanical services design   The project: Refurbishment of two semi-detached social housing cottages in North Devon, completed 2011, renovated to almost EnerPHit standard   Our focus: At first glance these houses look perfect for a cost-effective retrofit: the external walls are only 100mm thick and are made of heavily reinforced concrete.  This means there is no cavity to worry about, and the thickness of the external insulation is not such a big issue.  As with all retrofits life is never that simple; our big mistake was assuming the concrete would be relatively airtight.  The final airtest results came in just under 1.2 air changes/hour, and a large chunk of that was through the party walls. We designed the mechanical services which comprised of a central biomass boiler for the two dwellings and individual MVHR’s.   Read more on Energy Action Devon’s blog     The team: Client:North Devon Homes Architect:Clive Jones Contractor: RR Richardson                ...
