Considering the new IPCC report and its recent suggestions, it is important to pay serious attention to the Urban Heat Island issue. In this study, satellite images acquired by the Worldview3 sensor (WV3) were processed to classify the different kinds of urban surface and to compute the albedo value for each surface.

Then several UHI mitigation scenarios were analyzed, varying selectively the surface albedo by choosing solar reflective materials. Clay tile pitched roofs, dark roofs and parking areas were considered as “modifiable surfaces” and their albedo values were increased on the basis of the literature and of data made available by product manufacturers.

For each proposed scenario, the reduction of intensity of the Urban Heat Island effect (ATD), the energy saving brought by lower absorption of air conditioning systems (ΔE) and the consequent cost savings were calculated. All the scenarios proved to be convenient and with a relatively fast return on investment. In particular, two scenarios involving the modification of several surfaces at the same time proved to be the most promising ones from the perspective of a public administration, with significant benefits on the well-being of the population, as well as with similar and relatively short payback periods.

考虑到IPCC的新报告及其最新建议，重要的是要认真关注城市热岛问题。在这项研究中，对Worldview3传感器（WV3）采集的卫星图像进行了处理，以对不同类型的城市表面进行分类并计算每个表面的反照率值。

然后分析了几种UHI缓解方案，通过选择太阳反射材料来选择性改变表面反照率。根据文献和产品制造商提供的数据，将粘土砖的斜屋顶，深色屋顶和停车区域视为“可修改的表面”，并且其反照率值有所提高。

对于每种提出的方​​案，都计算了城市热岛效应（ATD）的强度降低，空调系统吸收率较低（ΔE）带来的能源节省以及随之而来的成本节省。事实证明，所有方案都很方便，并且投资回报相对较快。特别是，从公共管理的角度来看，两种涉及同时修改多个表面的方案被证明是最有前途的方案，它对居民的福祉具有重大好处，并且相似且相对较短投资回收期。
