Research on Passive Design Strategies of Aquaculture Building in Hot and Humid Area

The purpose of this study is to improve the quality and efficiency of a land-based aquaculture building in Guangzhou， addressing issues such as high temperature and humidity in the working environment， as well as high energy consumption. The research methods include： 1） sorting out design specifications and pointing out that there are significant gaps in the green design specifications of this type of agricultural building； 2） conducting measurement in summer and questionnaire surveys to reveal problems such as high temperature and humidity in the indoor environment and insufficient lighting during building operation； 3） based on a passive design approach， focusing on natural ventilation， natural lighting， building envelope， photovoltaic power generation， and environmental friendliness， short-term and long-term design solutions are proposed； 4） combining wind-thermal environment， light environment， and energy consumption simulations to verify the effectiveness of the design solutions. The main conclusions are as follows： 1） natural ventilation is a key measure for regulating the indoor thermal environment. By enhancing natural ventilation， thermal comfort needs during summer and transitional seasons have been optimized； 2） in combination with the window system， the indoor natural lighting has been optimized synchronously， to save lighting energy； 3） the introduction of photovoltaic power generation can meet the energy needs during summer and the transitional seasons， but due to the large energy consumption for water body insulation in winter， there is still a certain gap in winter power generation； 4） the comparison of schemes shows that the standard building can ensure the comfort of the indoor working environment， while the experimental building more comprehensively moves towards the goals of energy saving， low carbon， comfort， and environmental friendliness. In summary， with a passive design approach， the problems existing in the working environment and equipment process of the aquaculture building have been systematically solved. The research path， design strategy， and technical measures proposed in this project are widely applicable to the research， design， and quality improvement of different types of industrialized agricultural buildings.
