| Abstract: | Modern society defines sustainable development as the use of resources to satisfy future generations. Economy, Society, and Environment are three aspects that need to be focused on for sustainable development. If society wants to develop, it will inevitably bring about a continuous increase in energy consumption. The extensive use of fossil fuels has resulted in extremely large carbon emissions. The emergence of sustainable energy has become the key to meeting sustainable development and reducing carbon emissions. Countries around the world reacted quickly and enthusiastically. In the end, the United Nations came up with 17 sustainable development goals. By 2030, both developing and developed countries will have embarked on their own sustainable development initiatives. Hong Kong has demonstrated rapid action under the theme of sustainable development. In 2021, Hong Kong published《Hong Kong's Climate Action Plan 2050》, which aims to reduce the use of fossil fuels and increase the proportion of renewable energy. Subsequently, the Hong Kong government established the Steering Committee on Climate Change and Carbon Neutrality, which aims to reduce carbon emissions by 2035 to half the level of the early 21st century. The Hong Kong government aims to move away from coal as much as possible by 2035 and gradually replace renewables with core power sources, which will account for at least 7.5% of power generation. The ultimate goal is to achieve net-zero power generation by 2050. However, the development of renewable energy in Hong Kong has its limitations, and land resources are scarce, so wind energy and water energy are difficult to occupy a high proportion of Hong Kong's power generation structure. Solar energy stands out, and vigorously developing solar energy is the best solution for Hong Kong's sustainable development There is a growing interest in sustainable building design and energy efficiency. Building shading plays a crucial role in improving energy performance, while solar photovoltaic (PV) technology offers a green energy solution. Bifacial solar PV panels, which can generate electricity from both the front and back sides, have emerged as a promising option for building shading. However, research on their use as shading devices is limited. The purpose of this project is to assess the effectiveness of solar shading panels that are mounted on a building's outside walls in Hong Kong. Examine the differences in performance between Bifacial solar PV and monifacial solar PV panels, accounting for many variables such as orientation and installation angle. Study how to achieve the most efficient conversion of solar radiation into electricity through Energyplus simulation, and minimize indoor heat gain. |
