    This paper focuses on the experiences and decision‐making processes of private homeowners who have successfully carried out low carbon retrofits which have reduced modelled CO2 emissions by more than 60%, very largely in the absence of policy support. The group studied are ‘Superhome’ owner‐occupiers. Superhomes is the UK’s largest and most long‐established open home network, where groups of owners open their homes to the public, to share their experiences and to inspire others to undertake work on their own homes (www.superhomes.org.uk). The majority (130) of Superhomes are owner‐occupied with the remainder (nearly 40) owned by landlords or research organisations. Through questionnaires and interviews, this research investigates Superhome owner‐ occupiers, their homes, their motivations and experiences of low carbon retrofit.

    An interesting read..

    Yes. *Very* interesting.

    Summary:
    These householders have renovated their homes and reduced carbon emissions by 60% or more.

    I'd be interested to know what 'modelled' means in this case. Modelling by RDSAP seems to have an "engineering approximation" range of from half to double of reality :tongue:.

    Dataset

    Property age

    More likely than the general population to live in pre‐1919 properties; the more recent the build date, the fewer Superhomes there are.

    Built form

    A relatively high proportion of detached or semi‐detached houses, and relatively few terraced houses. Very few flats.


    That asks the question whether older houses are easier to improve as they are worse to start with, or more difficult because they are older houses.

    To me it says that the sort of people interested in these things are the comfortably off middle classes, who are much more likely to live in detached "character" houses.
