I’m trying to make my flat a SuperHome – a network of exemplar, old dwellings which have undergone an energy-efficiency retrofit. This means I have to improve its energy efficiency by over 60%. I’ve had the initial assessment done to show the starting point. It looks like I’ll be close to the mark when it’s finished but I may be let down by my windows, which are not so easy to double glaze – see blog on this. Superhomes are aiming to create a network of homes that are local and publicly accessible, within 15 minutes, to nearly everyone in the country.
