Normally in the preliminary phase of an EPC contract an EPC Facilitator is involved. The EPC Facilitator provides the necessary know-how and experience to support the building manager with the successful implementation of an EPC project. The EPC Facilitator acts as a mediator between client and ESCO to build up a sustainable relationship and to create trust between the future contract partners.

Often activities such as check on historical building consumption, existing contracts (either on supply of energy or on O&M), general conditions of the buildings, check on saving potential and estimation of the volume of investment are carried out by the EPC Facilitator (i.e. energy agency or similar) along with the Energy Manager of the Public Body.

These activities are aimed at assessing the suitability of the concerned building(s) for an EPC contract.

The basis of the energy costs baseline is the energy consumption in a reference year (e.g. past year before implementation of EPC) in connection with the energy supply prices applicable to the client at a certain key date (e.g. 31/12 of the reference year).

The baseline is to be provided to all bidders in the invitation to tender. They will prepare their saving forecast on this basis. In the context of the implementation planning, the baseline might be finally checked and confirmed by the contractually bound ESCO.
