The present practical guidelines have been developed within the TEMPO project. They should guide technicians in performing audits on energy systems in building to identify, diagnose and correct components or systems behaving in a suboptimal way.

The flowcharts offer a first to gradually narrow down issues, and thus refer the user to issue profiles corresponding to probable issues.

Issue profiles provide more detailed information on specific types of issues, grouping together issues affecting given components and/or sharing similar mechanisms or symptoms.

Links are also provided between issues and metrics which are related to them and might support diagnosis.

General information on issues causing high return temperatures and references can be found in the last sections.
