Bringing Wates homes into the Future

Wates property structural and low energy refurbishment based on an optimised structural insulated render consisting of a steel cage filled with insulation (Structherm). The void created allows for plumbing and ventilation ducting to provide heat recovery air heating and vent control throughout the house from a heat exchange unit located in the roof space. Other features include air source heat pump supplemented by solar and PV cells, triple glazed windows and doors with reveal detail to improve sealing and solar gain, weather compensating energy controls and a broadband based monitoring system to enable point of use metering information. A porch to reduce energy loss from front door and veranda at the rear for washing to reduce energy...

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

City West Homes - Low Carbon Retrofit in the Queens Park Estate Conservation Area

This project will focus on a mid-terrace, 2-bed property in the heart of the Queens Park Conservation Area. This project will build on that experience, learning from both its obstacles and successes whilst seeking to apply those lessons within the more challenging context of a 59m2 Conservation Area property. Our approach to energy saving and CO2 reduction will follow a lean-clean-green hierarchy: seeking to minimise heat losses from the property thermal fabric and ventilation method; to supply residual space and water heating using replicable, low carbon technology; to minimise lighting energy loads; and finally to consider micro-generation using proven, renewable energy systems.
