In Brislington, Jos has a lovely garden outside and a snug home inside thanks to 2013 Bristol City Council insulation scheme. Plus an electric car charging point.

Cotham householder Mike has loads of experience to share around planning issues in a conservation area and how to generate and manage energy at home.

A Predicted Energy Assessment rating of 101? No we had never seen that before either. Worth a trip to Stoke Bishop to see this award winning home, where the hosts are serving tea and cake too.

In Cliftonwood, this popular and regular Green Doors "Superhome" shows how insulation and thermal mass together radically reduces the heating demand on a large home.

An Easton man's home is "off gas" and has the same solar panels as on an Antarctic research station. Come and see how this works and what it saves him.

When Rose Cottage in Kingsdown opened last year it was still work in progress. Come and see how well it has turned out and how Toms plans for low energy consumption have worked.

A typical Easton house has been carefully and sensitively overhauled with a high emphasis on natural materials. Really worth a look.

Four households worked together to insulate their terrace's rear and side walls. Steve and Marco will tell you about this great collaborative project in St Andrews.

A whole estate was built in Kingsdown in the 1970s. One house has now been completely refurbished to be far warmer and cheaper to run for its tenants.
