| dc.title | A study of day lighting environment under different plot ratio/building height restrictions : a case in Hong Kong | en_US |
| dcterms.abstract | As an international metropolis, Hong Kong now is facing numerous of challenges, which generally addresses the unbalance situation in land supply-demand. Hong Kong struggles to development the intensive land use for maximum its fundamental needs of social, economic and environmental developments. Through the literature review of the planning and design consideration, day lighting environment and feasible studies using Autodesk Ecotect Analysis, including the previous works in the team, it presents theoretical framework for the further study of plot ratio and building height restrictions in Kai Tak Development Area. By the 3D spatial modeling analysis methods, composing the model establishment and solar radiation analysis, it systematic illustrates the resolution processes for the comparison of plot ratio and building height restrictions. It presents detailed data sources, preliminary design procedures of the 3D model, and the analysis techniques in the modification of building orientation and the solar radiation levels. It generally points the optimal building orientations in Hong Kong, by considering the optimized features of incident solar radiation, sunlight hours, the land intensive use and the natural ventilation, then suggests 192.5 degree (0 degree as north) as the optimum meteorological parameter based statement. Furthermore, it analysis the solar exposure levels, including direct and diffuse solar radiation, in all the three study areas at 4th Aug and 5th Feb to provide the isolation calculation and shadow ranges. It provides both the visual analysis supported by such 3D spatial techniques and the quantitative tables with exactly values of each test node (the statistical results are shown in the dissertation body and the original output data is attached in the appendices). Finally, it concludes that scenario 3 and 4, the situations in both summer and winter, suppose slightly changes compared with scenario 2, but scenario 5, as the extremely scenario, causes significant changes in both summer and winter days. By the increasing of the plot ratio and building height, the weaken scope of solar radiation becomes larger and larger in each contour of isolation level. | en_US |
