“双碳”背景下闽东南沿海城市通风光伏屋顶设计策略研究——以福州市某高校体育馆为例

Research on the Design Strategy of Ventilated Photovoltaic Roof in Coastal Cities in Southeast Fujian in the context of"Double Carbon"—An Example of the Gymnasium of a University in Fuzhou

“双碳”目标下,光伏发电被作为减碳有效手段快速发展,传统通风屋顶由于达不到理想效益被逐渐淘汰。以福州市为例,通过考虑风向指标和太阳高度角,研究一种适用于东南沿海城市的通风光伏屋顶。采用Cite Space数据分析、Ecotect和PHOENICS软件数据模拟检验研究假设,得出新型可调节通风光伏屋顶能最大限度利用太阳辐射实现产能效益,根据季节调整安置角度能够有效改善建筑室内热环境的结论。对“双碳”目标下未来城市建筑更新起到良好的推进作用。

In the context of"Double Carbon"target,photovoltaic power generation is developing rapidly as an effective means of carbon reduction.The traditional ventilation roof is gradually eliminated because it can not reach the ideal benefit.Taking Fuzhou area as an example,this paper studies a ventilation photovoltaic roof suitable for southeast coastal cities by considering wind direction index and solar height Angle.Using CiteSpace data analysis,Ecotect and PHOENICS software data simulation to test the research hypothesis,the following results were obtained:The new type of adjustable ventilation photovoltaic roof can maximize the use of solar radiation to achieve productivity benefits,and can adjust according to the season,effectively improve the indoor thermal environment of the building,and has a good role in promoting the future urban building renewal under the"double carbon"goal.
