25、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
26、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. This European Standard also gi
27、ves 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 coolin
28、g load impacts on the combined total energy 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

31、) 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 e
32、xisting 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 to
33、tal 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
34、 manufacturing 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
35、 from 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 r
