BS EN 15193:2007EN 15193:2007 (E) 5 Introduction This European Standard was devised to establish conventions and procedures for t
24、he 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 stand
25、ard 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. This European Standard also gives advice on techniques for separate mete
26、ring 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 energ
27、y performance of building indicator. Figure 1 gives an overview of the methodology and the flow of the processes involved. The methodology and format of the presentation of the results would satisfy the requirements of the EC Directive on Energy Performance of Buildings 2002/91/EC. BS EN 15193:2007E

29、7 1 Scope This European Standard specifies the calculation methodology for the evaluation of the amount of energy used for indoor lighting inside the building and provides a numeric indicator for lighting energy requirements used for certification purposes. This European Standard can be used for exi
30、sting buildings and for the design of new or renovated buildings. It also provides reference schemes to base the targets for energy allocated for lighting usage. This European Standard also provides a methodology for the calculation of instantaneous lighting energy use for the estimation of the tota
31、l energy performance of the building. Parasitic powers not included in the luminaire are excluded. In this European Standard, the buildings are classified in the following categories: offices, education buildings, hospitals, hotels, restaurants, sports facilities, wholesale and retail services and m
32、anufacturing factories. In some locations outside lighting may be fed with power from the building. This lighting may be used for illumination of the faade, open-air car park lighting, security lighting, garden lighting etc. These lighting systems may consume significant energy and if they are fed f
33、rom the building, this load will not be included in the Lighting Energy Numeric Indicator or into the values used for heating and cooling load estimate. If metering of the lighting load is employed, these loads may be included in the measured lighting energy. 2 Normative references The following ref
