Not fit for purpose



EPCs are not fit for purpose with an industry insider warning of bogus surveys


Carbon emissions from homes with high 'EPC ratings' have been proven to be little different from poorly insultated properties, a new study has found.

The study compared estimates of CO2 emissions from 1,038 homes based on their Energy Performance Certificate rating with measurements derived from actual meter readings from these same homes.

The meter readings in the study showed minimal variations in emissions between properties of very different EPC ratings.



It's jaw-dropping stuff when a box-ticking game actually turns out to be a box-ticking game. Fraud and fakery in the CO2 emissions game as well apparently. 

Whatever next? Ed Miliband turns out to be an absurdly intransigent and ludicrously destructive ideologue? 

Cripes!

I assume the EPC rating is about as meaningful as using your shoe size to assess your fitness. As with so many 'measurements' nowadays it relies on observation, assumption and quesswork to produce a pseudo-scientific value which is then touted as absolute fact to be used for further purposes. See also CO2, Global warming, OBR forecasts, HS2 costings etc.

“… a box-ticking game actually turns out to be a box-ticking game...”

That’s exactly what it is, I believe. The “assessor” inputs a few simple responses into a pretty basic (see what I did there?) Excel spreadsheet and out pops a number. No context, no understanding, no intelligence.

NWTPIPO.

Woodsy - yes, observation, assumption and guesswork plus some things which have more to do with government policy than saving energy.

Peter - and everyone involved takes it seriously because there is money in it. Crazy games they play, but the money keeps it going. NWTPIPO?
