BS EN 15193-1 is the first part of the multiple series that specifies the methodology for evaluating the energy performance of lighting systems for providing general illumination in residential and non-residential buildings and for calculating or measuring the amount of energy required or used for lighting in buildings.
BS EN 15193-1 specifies three methods for evaluating the energy performance of lighting systems.
The method may be applied to new, existing or refurbished buildings. It also provides a methodology (LENI) as the measure of the energy efficiency of the lighting installations in buildings.
NOTE-
BS EN 15193-1 does not cover lighting requirements, the design of lighting systems, the planning of lighting installations, the characteristics of lighting equipment (lamps, control gear and luminaires) and systems used for display lighting, desk lighting or luminaires built into furniture.
BS EN 15193 does not provide any procedure for the dynamic simulation of lighting scene-setting.
BS EN 15193-1 on requirements for lighting of buildings is useful for:
The convention and procedures in BS EN 15193-1 help you ensure that the designed and installed lighting scheme conforms to good lighting practices. For new and refurbished installations in the non-residential building sector, the design of the lighting system conforms to the requirements in the lighting applications. Smart meters improve your awareness of energy consumption.
An artificial lighting system enables you to work in the dark. BS EN 15193-1 specifies three methods for evaluating the energy performance of lighting systems. i.e., calculation of the energy required for lighting, quick calculation of the energy required for lighting, and metered energy used for lighting. BS EN 15193-1 enables you estimate or measure the amount of energy required or used for lighting in buildings.
The methodology of energy estimation not only provides values for the Lighting Energy Numeric Indicator (LENI) but it will also provide input for the heating and cooling load estimations for the combined total energy performance of building indicator.
BS EN 15193-1 suggest separate metering of the energy used for lighting which helps you to give regular feedback on the effectiveness of the lighting control.
BS EN 15193-1 aims at international harmonization of the methodology for the assessment of the energy performance of buildings, called “set of EPB standards”. All EPB standards follow specific rules which help you ensure overall consistency, unambiguity and transparency.
BS EN 15193-1:2017+A1:2021 supersedes BS EN 15193‑1:2017, which is withdrawn.
The revision for inclusion in the second mandate package was performed during 2013-2016.
