This paper describes the framework for a proposed certification for energy consultants targeting the grocery sector, i.e. supermarkets. Thecertificationshould cover necessary knowledge and requirements, with the overall aim of increasing energy efficiency and reducing related costs for the store at the system level. Within the retail sector, supermarkets are the most energy-intensive buildings. Buildings intended for food sector applications need to be of a special design, with requirements that differ from other premises. Half of the electricity used is employed to keep food cold. However, energy efficiency can be improved through efficient equipment and increased knowledge, sometimes by 30-50% or more. This paper presents different skills and requirements needed by a certified energy consultant, CEC, working with energy efficiency in supermarket, from the retailer's perspective. Thus, the specifications can be used to further develop the certification area; energy consulting for supermarkets and good practice approaches targeting this area.
