  • Billing analysis [GUIDE 6]
    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.

  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)
