It gives general principles and identifies the key factors to consider. It also defines roles and responsibilities, recommends the required competence and provides key elements for assessing the knowledge and skills of energy savings evaluators. At the project and organization level, this document is applicable to both internal and external energy savings evaluators. Selecting evaluators who calculate predicted energy savings is out of the scope of this document. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply.
