| Abstract: | The content of this dissertation has two main sections. The first section is to investigate the lighting design methods for obstructed interiors and the next section is to propose an interior lighting design approach for Hong Kong. In the first section, a case study is set to investigate the working plane illuminance determined by three different methods used for obstructed interior lighting design. They are Lumen design method for obstructed interiors by Carter et al. [Refs. 1 and 2], Computer software Lumen - Micro and Point - by - point calculation method. After the case study of obstructed interior lighting design, the advantages and disadvantages of these three methods are discussed. An experimental study is performed to demonstrate the deficiencies of the method of Carter et al. with respect to different partition arrangements. The best tool for obstructed interior lighting design is proposed and existing IESNA partitioned space calculation concept is investigated and recommendations to enhance this concept are suggested. In the next section, CIBSE and IESNA lighting design methods for empty and partitioned interiors are investigated. A case study is set to compare the results calculated by these two methods. The disadvantages of these two methods are then discussed. Finally, an interior lighting design approach suitable for Hong Kong is proposed, which includes design illuminance recommendation, factor for light loss, factor for utilisation, uniformity, discomfort glare and partitioned space calculation. |
