Investigation Of The Strategies And Methodologies For Zero Carbon Solar Builging At Tropical Island

With highlighting the importance of island space,some countries or organizations have put their eyes on the building energy conservation in developing the islands.As a high-level product of energy-saving buildings,the research and utilization of zero-carbon solar buildings has gradually become the main way to realize the ecological development of island.At present,the development and construction of South China Sea islands are advancing step by step,but the research on the strategies and methods of zero-carbon solar buildings in this area is basically in a blank state.Therefore,this paper integrates the content of solar energy application technology as an indispensable design element of building,it can not only effectively reduce the construction cost,reduce the energy loss caused by the building,but also improve the comprehensive efficiency of solar energy utilization,so as to better build zero-carbon solar energy buildings in line with the tropical island environment.Firstly,based on the analysis of the regional environmental characteristics,solar energy resources potential,residential building energy season and energy proportion in tropical island area,the basic model parameters of zero-carbon building based on solar energy utilization are determined,and the integrated optimization system model design of solar energy building is established.Secondly,through the integrated design of solar collector components and building interface,the solar building envelope module is formed.This module can not only effectively improve the basic functions of building interface such as thermal insulation,but also fully capture solar energy resources to realize the independent supply of building power and hot water.Thirdly,the solar energy building envelope module is coupled with the indoor equipment to make the solar energy system truly become a part of the whole building.While controlling the impact of solar energy system on building energy utilization and indoor thermal environment,it can also effectively impr ove the overall efficiency of solar energy utilization.Fourthly,according to the comprehensive load of the model building,the position and quantity of the collector module are arranged,and the application and compensation design of the solar energy system are completed at the same time.The energy consumption simulation software Energy Plus is used to simulate the energy supply and operation energy consumption of the model,so as to make a preliminary design evaluation on the feasibility of zero-carbon solar architecture design in tropical island areas.Finally,the stages and ranges of the whole life cycle of solar energy buildings are divided,and the economic,energy and environmental benefits of solar energy buildings are analyzed through the model building parameters.The economy and feasibility of solar energy buildings in tropical islands are further demonstrated,which can provide reliable and objective reference for other regional environments with similar climate characteristics.
