- Measurement [GUIDE 23]
The measurement method requires measuring of the energy consumption of a single piece of equipment or a single installation to calculate the gross energy saved. Corrections may be needed to calculate the net energy savings, for example for the operational hours. The method will provide the energy savings for a single installation or piece of equipment.
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 | |
| Measurement | 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: passenger transport / deemed savings [GUIDE 26] |
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) |
| Econometric modelling Fallback methodology: industry general / econometric modelling [GUIDE 25] |
Explanation of relations | Possibly missing factors | Total savings | Top-down | Ex-post only | For (sub)sector | Depends on case | Depends on case | For behaviour, temperature, activity level | No (if covered in method) |
