TS EN 16247-2

TS EN 16247-2. OFFICIAL SCOPE IS UNAVAILABLE. This standard addresses energy audits for buildings, meaning the systematic assessment of how a building uses energy, where losses or inefficiencies may occur, and where improvement opportunities can be identified. In general technical terms, a building energy audit looks at the envelope, HVAC systems, lighting, occupancy patterns, controls, and operating practices that influence overall energy performance.

What a building energy audit means in practice

An energy audit is more than reviewing utility bills. It is an engineering-led process for understanding where energy is consumed, why loads arise, and which measures may reduce consumption or improve efficiency. In a building context, this usually involves heating, cooling, ventilation, domestic hot water, lighting, and plug loads, considered together rather than in isolation. The value of the audit lies in turning scattered data into a prioritised view of saving opportunities.

Building energy use results from the interaction between the physical fabric and the way the building is operated. Insulation, airtightness, glazing performance, zoning, control strategies, schedules, and user behaviour all affect demand. For that reason, building audits combine site observations with technical data to identify measures that are realistic for the specific building and its use pattern. Based on the title alone, this listing is clearly focused on buildings as the audit subject; detailed clause-by-clause requirements are not verified here.

• Technical and operational factors that shape building energy consumption
• Integrated consideration of heating, cooling, ventilation, lighting, and related systems
• Identification of saving potential through measurement, observation, and data analysis
• Interpretation of improvement options in relation to building use and system interactions
