Where to start with energy efficiency

Start by clarifying the purpose of the review, the asset or process involved, the available source documents, and the decision the findings will support. Different assignments require different evidence and methods.

Before work begins, document the scope, acceptance criteria, access requirements and expected deliverables in a clear brief or terms of reference.

Technical opinions and analytical reports should rely on verifiable evidence; regulated activities must be carried out by appropriately authorised professionals.

If the initial evidence is incomplete, agree any additional measurement, inspection or analysis before proceeding.
