  • Engineering estimate [GUIDE 16]
    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.

Evaluation methodology comparison table

Evaluation method Pros & cons Method characteristics Required input data
  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
Billing analysis
Fallback methodology: residential / billing analysis [PSMC 8]
Easy Too aggregated Unitary, participant Bottom-up and top-down Ex-post only For each participant By complementary method No, follows from method For behaviour, temperature E.g. free riders (in case of subsidies)
Deemed savings
(alternative method as mentioned in the current PSMC engineering estimate [PSMC 16])
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
Energy indicator sector (energy intensity)
Fallback methodology: non-residential / subsector indicator [PSMC 12
Fallback methodology: agriculture / subsector indicator [PSMC 18]
Only statistics Aggregated (black box) Total savings Top-down Ex-post only From statistics No (included in total savings) No (included in total savings) For activity level and temperature E.g. double counting
Energy indicator equipment (unit consumption)
Fallback methodology: industry general / (subsector indicator/unit consumption) [PSMC 17]
Easy (trend) Only uniform systems Unitary, system Bottom-up Ex-post only Per average unit of equipment By complementary method No, follows from method For behaviour, temperature, activity level E.g. double counting
