- Billing analysis [GUIDE 24]
The billing analysis method requires energy meter readings (often from surveys) as input data which are used to calculate the gross energy saved. Corrections may be needed to calculate the net energy savings. In the case of dwellings the corrections needed are for the outside temperature, the occupancy and the behaviour of occupants. The method will provide the energy savings for a single dwelling, 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 | |
Billing analysis | 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 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) |
