BS EN 15193:2007

BS EN 15193:2007 was devised to establish conventions and procedures for the estimation of energy requirements of lighting in buildings, and to give a methodology for a numeric indicator of energy performance of buildings. It also provides guidance on the establishment of notional limits for lighting energy derived from reference schemes.

Having the correct lighting standard in buildings is of paramount importance and the convention and procedures assume that the designed and installed lighting scheme conforms to good lighting practices. For new installations the design should be to EN 12464-1.

BS EN 15193:2007 also gives advice on techniques for separate metering of the energy used for lighting that will give regular feedback on the effectiveness of the lighting controls. The methodology of energy estimation not only provides values for the numeric indicator but will also provide input for the heating and cooling load impacts on the combined total energy performance of building indicator.

BS EN 15193:2007 contains:

• Normative references
• Terms and definitions
• Calculating energy uses for lighting
• Metering
• Calculation of lighting energyin buildings
• Benchmark of lighting energy requirements
• Lighting design and practice
