[en] The global report of the SNEC survey 2020 proposes an overview of the context (recall of French objectives regarding energy and ecological transition), presents Energy Performance Contracts as a solution for energy efficiency, discusses the role of the SNEC in the development of these contracts, describes the role of these contracts in the arrangement related to Energy Saving Certificates (CEE), and proposes an overview of the situation. Then survey results are presented: panel presentation, analysis of CPE contractual commitments, analysis per types of action of energy performance. The results of the survey are discussed in terms of development of energy performance contracts over time, of results in energy savings, of benefits in energetic renovation. Statistical data are also presented and briefly commented, notably for the residential sector (different types of housing and of heating systems), housings with collective heating, objectives of energy savings, energy efficiency. This document also proposes reports for 2019 and 2017 which address heating types, the role of CPEs, the main undertaken actions (global, technical, and service-related CPEs), the commitment for performance, opportunities of energy saving in collective housing. Recommendations are stated by the SNEC.
