| Abstract: | This dissertation examines the existing public area lighting of the Hong Kong Housing Authority (HKHA) with 4 target Block types: Slab Block, H-Block, Trident Block and Tower Block. The design, maintenance practice and operation method of the public lighting of each block type are analyzed to find out methods to achieve the best balance between economical consideration and occupants' acceptance. During the process, a survey is carried out to find out tenants' opinion of existing public lighting. It is found that tenants generally are not satisfied with the existing public lighting. To find out the reasons, the design of public lighting for the aforementioned 4 block types is analyzed with the use of computer modeling. It is found that the existing illuminance standard of HKHA is low compared with international standards from the Illuminating Engineering Society (IESNA) and the Chartered Institution of Building Services Engineers (CIBSE). The existing public lighting does not provide enough light to corridor but sufficient to lift lobby. Thus, HKHA should revise its existing illuminance standard and the design of public lighting. Meanwhile, since HKHA does not have maintenance schedule for public lighting, a 5 years interval of bulk lamp replacement and luminaire cleaning is suggested to make sure that the illuminance depreciation of public lighting is within a reasonable level. Meanwhile, the operation of existing public lighting is by timer and is not flexible. It cannot provide tenants illuminance whenever surrounding illuminance is not enough. In contrast, light-sensor control can provide light according to the change of environment by switching on or off public lighting accordingly. Thus, light-sensor control is a better alternative of the existing timer control. In order to provide sufficient illuminance to tenant, HKHA is recommended to revise its design, maintenance practice and operation method of existing public lighting. |
