- Energy indicator equipment [GUIDE 17]
The equipment energy indicator method (also called unit consumption method) concerns the calculation of unitary savings for energy using systems, like appliances or equipment. The equipment considered is very much dependent on the subsector. The equipment energy indicator method uses an indicator on energy consumption per unit of physical output. For example, the energy required to produce one tonne of steel. The indicator approach is closely related to the concept of unitary savings applied in most evaluation methods.
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 | |
Deemed savings Fallback methodology: appliances / deemed [PSMC 14] |
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 (alternative for subsector modelling mentioned in PSMC 17) |
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 equipment | 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 |
