Thamesmead Retrofit House

This highly ambitious project aimed to refurbish a pre-cast concrete panel end terrace in the Thamesmead Estate, South-East London. The team created an innovative, robust and replicable refurbishment solution, which cut 80% of the dwellings carbon emissions, achieving high levels of comfort at attractive costs. The property was transformed from a four bedroom hard-to-treat property into a six bedroom super-insulated home supporting a 7-person family. The scheme includes external cladding, triple glazing and high levels of air tightness. Fresh air is provided by a mechanical ventilation system with heat recovery (MVHR). Ten photovoltaic (PV) panels and a vacuum tube collector on the roof provide renewable electricity and water heating. A gas boiler is provided to meet the peak heating load. A key innovation is a highly-insulated solar-air heater containing a super-insulating aerogel cover integrated into the external insulation on the south faade pre-heating the MVHR on cold sunny days.

Grove Cottage

Extension & Refurbishment of Victorian Townhouse using Passivhaus methodology and CarbonLite guidance. Certified to the Passivhaus Institute's new EnerPHit (refurbishment) Standard. [NEW:Passivhaus Trust awards shortlisted project - presentation available on these pages].PHPP certification is based on 20 C, rather than the 21 C the house was heated to during 2010/11. Forecasts are based on a 'typical year' rather than the 'actual' year being monitored. Measured data here is from 2005/06 (before) and 2009/10 (after). Measured room temperatures show an average of 21 degrees centigrade during the heating season. Please note the final air leakage as certified under EnerPHit was an N50 of 1.0 ACH. When adjusted for 2010 average monthly temps.& an internal temp. of 21 C, PHPP predicted a space heat demand of 36kWh/m2.a whereas 35kWh/m2.a was measured.

Hounslow Passivhaus Retrofit

This social housing retrofit by bere:architects, will be Enerphit passivhaus making use of external insulation, new windows, and heat recovery ventilation to ensure fresh air at the same time as very low heat loss. Specific heat energy requirements will be reduced by 95%, while alsominimizing primary energy use. The existing property has an abnormally high energy demand asassessed using the Passivhaus Planning Package (PHPP). These large values are in part due to a complete absence of loft insulation. The main objectives of the project are to show that deepenergy cuts are possible with social housing stock. As UK exposure to and experience of Passivhaus grows, we aim to show that improved thermal comfort, reduced energy bills and lower CO2 emissions are possible for millions of people in existing houses.

Wake Green Road - Attempt to renovate to Passivhaus standard

This project is an attempt to take a 1920s detached house and make it as near to passivhaus as possible, although this probably means enerPHit (if we're lucky). 300mm external EPS on three sides, internal insulation on fourth (boundary) wall together with 300mm underfloor and full loft insulation. Air tight envelope design issues included eliminating thermal bridging at eaves level caused by the need to accommodate increased wall width, and the transition from internal to external insulation on the fourth wall. Planning requires reinstatement of appearance of front of property but the rear has been totally redesigned to maximise solar gain. Green roof on one-storey extension; solar (hot water) panels; greywater recycling unit for one shower/toilet; rainwater recycling rejected due to high environmental impact/not carbon neutral.

Elliott Drive (EnerPHit)

58 Elliott Drive in Wellesbourne is the second certified EnerPHit project in the UK. Built in the 1940s, this semi-detached dwelling, owned by Orbit Heart of England Housing Association is one of a number of speedily built properties that were built to tackle the post war demand for new housing and whose construction is well known for poor thermal performance and associated problems with high heating bills and condensation. Fuel bills for a house of this type would typically cost around 1,100 a year (if mains gas is available), while the transformed building should now cost just a couple of hundred to run.The building has been upgraded with a 200mm layer of high performing insulation throughout. The existing solid floor slab was excavated to make space for insulation in the ground floor. Internal load bearing walls were removed and rebuilt with a thermal break inserted. uPVC triple glazed windows were positioned in the external wall insulation layer and supported on timber bearers.

Thornhill Road

Thornhill Road is a EnerPHit certified retrofit of a 1950s detatched house. Project measures included a new PIR insulated ground floor slab, EPS external wall insulation, mineral wool pitched roof insulation, PIR flat roof insulation and green roof; triple glazing , MVHR, low water use appliances and sanitary ware and solar PV.The project was carried out by clients, architects and builders with no prior knowledge of Passivhaus techniques and building, with the support of experienced energy and airtightness consultants. The total budget was under 1000 per m2 including design, build, certification and finishing. The final result of airtightness at 0.32ACH and 23kWh annual heating demand demonstrate that, with care, novice teams can achieve great retrofit results.

Bristol Retrofit

A full thermal retrofit of a mid-century, three-storey property built into a hill and located within a Conservation Area in Bristol. The project included an extension, designed and built to a very energy efficient specification. The extension was needed, both to accommodate home-based business facilities, and to improve access to the lower floor, which is now the kitchen/dining area. A key challenge for this project was to address the amount of thermal bridges created by the excess amount of concrete used during the period of the original construction. Concrete gutters and a balcony have been removed. External wall insulation has been used throughout (U
