    I recon that I could do an EPC from a satellite photo of the house and a shore questionnaire!

    What do the rest of us think?

    Slough councils done it for use , its just a shame no bugger knows ( or cares ) about it in my area , and it's hidden deep in thier web matrix

    EPC , dont know much about them , but they seem pointless , am I missing something

    they are pointless and a bit meaningless but all home sellers need one as do all landlords.

    As it happens I just did an EP evaluation from a satellite and nothing else (but using specialised software that isn't significantly different or better than the standard stuff)

    We came up with £15,000 a year for heat & water whereas the actual yearly bill is/was £18,000. Not too bad?

    Hi Tony

    No idea to be honest: The estimation was done for a 200 room Country Hall to allow various unusual renewable technologies' business case to be tested. It just so happens that the owners ( a refreshingly pro-active lot) already had the Carbon Trust in to do an evaluation so I had a good comparison of theoretical (from satellite) versus real.

    nice one -- was the satellite looking at visible light or infra red?

    What does a satellite image tell you that you can do an assesment?

    Hi Tony: Just dimensions and construction type (very quick and dirty)
    Bot: Local weather data then used to estimate usage comparing to similar usage patterns.

    So presumably you could do the rest of the UK now? :bigsmile:

    Could do, but the results would be even more pointless than the current EPCs

    :wink:
