[en] After a recall of the definition and principle of operation of the CEEs (Certificate of Energy Saving) and of the concerned actions of energy saving, a brief indication of the extension in time of a fourth period for this certificate, and a discussion of its perpetuation and evolution, this publication comments the content of the different standard sheets, notably those which concern heat and cold networks. These sheets address various aspects: network insulation (for the primary and secondary networks), the optimisation of adjustments and consumptions (for the primary and secondary networks), temperature management (for the primary and secondary networks), the connection to a heat network, heat recovery. Possible evolutions and possible new sheets are evoked. Several appendices are provided which give actual examples of these sheets
