  • Engineering estimate [GUIDE 3]
    This method requires data on the amount of energy saved as a result of the changes in large specific installations. Engineering estimates are a very suitable method for this. The method will provide the energy savings for a single installation. In this case the energy savings in different installations will differ quite a lot, which requires collecting the energy savings results of all installations separately and add them up to get the total effect of the policy.

  Pro Con Savings output Aggregation level Application (ex-ante/ex-post) Energy use before and after actions Number of energy saving actions Energy saved per action Normalisation factors Gross-to-net adjustments
Measurement
Fallback methodology: normative residential measurement [PSMC 1]		 Precise Expensive Unitary, system or participant Bottom-up Ex-post only For each system or participant By complementary method No, follows from method For behaviour, temperature E.g. non-compliance
Deemed savings
Fallback methodology JG: normative residential deemed [PSMC 2]		 Cheap Imprecise Unitary, mostly system Bottom-up Ex-ante and ex-post No (covered in savings) By complementary method To be estimated No (covered in method) E.g. free riders (in case of subsidies)
Engineering estimate Precise Expensive Unitary, complex system Bottom-up Ex-ante and ex-post For each system By complementary method No, follows from method No (method on normalised case) E.g. non-compliance
