General description
Conversion of the 1930s Globe Pub into modern highly insulated houses.
Work started Oct 07, and project completed May 09.
Annual energy use
no figures available at present
Why we did it
Go Green converted the pub into 4 dwellings trough seizing the opportunity to create a prototype example of applying eco-renovation technology to existing buildings, rather than a new build.
Heating and power
Gas system boiler which provides the underfloor heating.
Insulation
Internal and external insulation was added to an average depth of 6 inches (approx 3 inches on inside and 3 inches on outside). Celotex high yield insulation was used throughout.
The roof was insulated to 8 inches, and underfloor insulation was used throughout.
Renewable Generation
The capacity of the renewable energy installation is 17,000 kwh per annum, with 48% being electricity and 52% hot water. By our reckoning this represents around 40% of the energy costs. This combines with a low start figure due to the high yield insulation and triple glazing.
• 48 panel solar photovoltaic array
(electricity). The Photovoltaic panels are
48 No. Kyocera 130 GHT with a capacity
of 130w each).
• 8 panel Solar thermal array (hot water).
The hot water panels are 8 No VITOSOL
100 panels with a potential output of
900w each.

Advice and information
Dr Chris Jardine of the Environmental Change Institute gave initial advice about renewable energy, and his company JoJu Ltd installed the solar photovoltaics
Insulation was rated by a company in Witney (awaiting further details).
Ray Foulk at GoGreen was the project architect, and GoGreen Contracting did all the building work.
Other info
About 70% of the interior lights are low energy, with a mixture of CFLs and Light Emitting Diodes.
“Great sense of comfort in the house – it's neither too hot nor too cold. It was extremely comfortable through the last winter, with a reasonable energy consumption.
It’s very quiet as the triple glazing not only prevents heat escaping, but stops noise penetrating.”
“It's amazingly gratifying to see the building go from dream to reality, and the finished house is very close to the original drawn ideas.”
“We had a great team of people getting all the details integrated into the house. For example the solar panels are kept on the roof using an innovative method to ensure that they didn't puncture the roof membrane or create a thermal bridge for heat to escape, the solar panels on the side of the house are recessed into the walls. “
“It's a great feeling of satisfaction now it's all completed,
It's good to see the number of people who stop outside to look at and talk about the house, explaining to each other how it works – the visibility and interest generated is part of the reason I converted it.”
Further advice
“If you're planning anything similar, the only three words I can say are insulation, insulation, insulation. It's really key, because if you can keep heat in, you don't need to worry so much about how you generate the heat. By insulating on the outside of the house as well as inside, we eliminated 'cold bridges'.”
When asked if he would do anything different, he mentions that maybe he would have angled the solar panels on the roof for a greater yield – but this can be done at a later date if required.
