Aiming for EnerPHit

In line with Superhomes week in September, we've decided to put some local case studies of low energy homes on the blog, some of which will open their doors to interested visitors (see previous posts)

Kate and Geoff's house in Derby is likely to become a Superhome very soon. This house is currently being refurbished to EnerPHit (the Passivhaus refurbishment standard).

This 1950s detached house is East-West facing and has been extended at some point to give 5 bedrooms, and a 1980s single storey extension. 

The refurbishment work includes insulation under floors, a "warm roof", external wall insulation (and some cavity wall insulation - rather odd original construction to say the least).

The work also includes Passivhaus-suitable triple glazing, a new boiler but some old radiators retained, lots

of water saving improvements, a recycled solar PV system, a tank suitable for adding solar hot water in the future, ...plus big fruit and vegetable plots, and ex-battery chickens!
