TS EN 16247-2

TS EN 16247-2 is the part of the energy audit series that addresses the specific rules for buildings. It complements the general framework in TS EN 16247-1 and provides a structured basis for how an audit in a building or building group is to be planned, what it should deliver, and which additional building-specific conditions need to be considered. Individual private dwellings are outside its scope; the focus is on energy assessment in multi-unit, commercial or institutional premises.

What building energy audits are meant to capture

An energy audit is a systematic review of how energy is used, where the main consumption drivers are, and where improvement opportunities may exist. In buildings, that usually means looking at heating, cooling, ventilation, domestic hot water, lighting and, where relevant, auxiliary systems as part of one operating picture. For a group of buildings, the analysis often shifts from a single asset view to shared operating logic, similar occupancy patterns and central systems that influence consumption across the portfolio.

How this part relates to the general audit framework

This part does not stand alone as a generic audit code; it adds building-specific requirements to the broader principles of EN 16247-1. In practice, that means the audit method and deliverables stay aligned with the general energy-audit framework while paying closer attention to the characteristics of the building stock, the intended use, operating conditions and the availability of data and measurements. The result is a more consistent audit approach for understanding building energy performance and comparing improvement options.
