摘要

近年来,气候和能源危机给人类带来了一些问题,甚至威胁到发达国家的生命。这导致了促进环境可持续性和脱碳的全球法规。在这个方向上,增加可再生能源的使用将是关键。因此,可再生能源发电的增加需要开发新能源园区,这需要大量的自由空间和大量的投资。因此,解决这个问题的一个有趣的方法是将光伏(pv)集成到人行道和道路上。本研究通过在雅典实施的一个试点项目来评估光伏路面的性能。该研究的重点是了解光伏路面在现实条件下的热行为、能源生产和小气候影响。实验测量分两个阶段进行,并辅以使用天气研究与预报(WRF)模型与建筑效应参数化(BEP)和建筑能量模型(BEM)的数值模拟来评估其气候影响。研究结果表明,与沥青和传统深色路面材料相比,清洁的光伏路面可以表现出更低的表面温度。尽管由于遮阳和材料特性造成了一些效率损失,但光伏路面产生的电力足以为研究区域的室外照明供电。虽然研究表明,当城市表面有很大比例被光伏路面覆盖时,当地环境和地表温度会小幅上升,同时城市边界层高度也会发生变化。这项综合评估强调了光伏路面作为可持续城市基础设施解决方案的潜力,提供了能源产生和城市微气候改善的双重效益。

Urban pavement-mounted photovoltaics as renewable energy systems for energy generation and microclimate control

Urban pavement-mounted photovoltaics as renewable energy systems for energy generation and microclimate control
Climate and energy crises have generated several issues for humanity in recent years, threatening life even in developed countries. This resulted in global regulations promoting environmental sustainability and decarbonisation. In this direction, increasing the use of renewable energy sources will be critical. Thus, increased energy generation from renewable sources necessitates the development of new energy parks, which need a large amounts of free space and significant investments. So, one interesting solution to this problem is to integrate photovoltaics (PVs) into pavements and roadways. This study evaluates the performance of PV pavements through a pilot project implemented in Athens. The study focuses on understanding the thermal behaviour, energy production, and microclimatic impacts of PV pavements under real-world conditions. Experimental measurements were conducted over two phases, complemented by numerical modeling using the weather research and forecasting (WRF) model coupled with the building effect parameterization (BEP) and building energy model (BEM) to assess their climatic impact. Results reveal that PV pavements, when clean, can exhibit lower surface temperatures compared to asphalt and conventional dark paving materials. Despite some efficiency losses due to shading and material properties, the PV pavement generates enough electricity to power outdoor lighting in the study area. Although the study reveals a minor rise in local ambient and surface temperatures, coupled with changes in urban boundary layer height, when a significant percentage of the city surface is covered with PV pavements. This comprehensive evaluation highlights the potential of PV pavements as a sustainable urban infrastructure solution, offering dual benefits of energy generation and urban microclimate improvement.
