- Billing analysis [GUIDE 15]
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: financial incentive / residential / deemed savings [GUIDE 9] |
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) |
| Stock modelling Fallback methodology: financial incentives / residential / stock modelling [GUIDE 10] |
Easy calculation | A lot of data needed | Number of actions | Bottom-up | Ex-ante and ex-post | No (see deemed savings as complementary method) | From method (stock/market data > replaced equipment) | Yes, from complementary method | See deemed savings as complementary method | E.g. free riders (in number of actions) |
| Diffusion indicator Fallback methodology: financial incentives / residential / diffusion indicator [GUIDE 11] |
Easy | Only for uniform systems | Number of actions | Bottom-up | Ex-post only | No (see deemed savings as complementary method) | From penetration rate per year | Yes, from complementary method | See deemed savings as complementary method | E.g. free riders (in number of actions) |
| Econometric modelling Fallback methodology: fiscal / all sectors / econometric modelling [GUIDE 21] |
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) |
| Econometric – Price elasticity Fallback methodology: fiscal / all sectors / econometric price elasticity [GUIDE 22] |
Simple (only price) | Situation dependent | Total savings | Top-down | Ex-ante and ex-post | For (sub)sector | No (included in total savings) | No (included in total savings) | No (method on normalised case) | E.g. double counting |
