确定太阳能在复杂城市环境中的实际应用潜力是一项艰巨的任务，特别是在缺乏背景信息的情况下，例如城市景观的纹理和结构，就像最近在希腊的情况一样。本文提出了一种简化而有效的方法来评估典型的多层多户建筑的平顶面太阳能适宜面积。它基于太阳能潜力的统计计算模型，该模型已通过分析在希腊北部城市塞萨洛尼基进行的实际测量而得到验证。该模型既可以被私人工程师使用，也可以被纳入地理信息决策工具，如GIS，以帮助规划者、监管者和开发商确定太阳能的潜力。最后，值得注意的是，验证中考虑的多户建筑的光伏潜力被证明相当差。在大多数被检查的建筑案例中，屋顶的太阳能利用率大约只在25%到50%之间。
Determining the actual solar potential for applications in the complex urban environment is a difficult task, particularly when there is a lack in background information, such as the texture and structure of the urban landscape, as this was until very recently the case in Greece. In this paper a simplified yet effective methodological approach for the evaluation of solar architecturally suitable areas of flat roof surfaces on typical multi-storey, multifamily buildings is presented. It is based on a statistical calculation model for solar potential that has been validated, by analysing actual measurements carried out in the city of Thessaloniki in Northern Greece. The model can be either used by private engineers or it can be alternatively incorporated in geoinformatics decision-making tools, such as GIS, to aid planners, regulators and developers to determine the solar potential. Finally, it is of great interest to notice that the PV potential of the multifamily buildings considered in the validation, proved to be rather poor. The solar utilization roof factor in the majority of the examined building cases was approximated only between 25 and 50%.
