TS EN 16247-2

TS EN 16247-2 defines the framework for planning, carrying out, and reporting energy audits for buildings. It addresses the requirements, methodology, and deliverables for an energy audit in a building or a group of buildings, and it functions as the building-specific companion to the general requirements in EN 16247-1.

In general technical terms, an energy audit is a structured review of how energy is used so that major consumption drivers can be identified. In buildings, that typically means looking at the building envelope, heating, cooling, ventilation, lighting, and occupancy-related patterns together, because these elements interact. The building focus helps separate the audit boundary from process energy or on-site transport energy when those are present.

Building-specific requirements used alongside EN 16247-1

This part adds building-focused requirements to the general energy audit framework and is applied simultaneously with EN 16247-1. If the audit scope also includes processes, EN 16247-3 may be applied; if on-site transport is included, EN 16247-4 may be chosen. In practice, that helps define whether the audit boundary is limited to the building itself or extends to other operational energy uses.

• Applies to energy audits for a single building or a group of buildings.
• Addresses the method and deliverables in a building context.
• Used together with EN 16247-1 as a supplementary part.
• Points to other EN 16247 parts when processes or on-site transport are in scope.
