Abstract:

Urban green spaces, such as parks and vegetation along roadsides, are readily recognisable examples of ecologically significant urban green areas. However, with growing human populations and limited space in cities, there is a rising trend for the adoption of space-efficient green solutions such as green roofs and green walls. While the ecological importance of residential and roadside vegetation is acknowledged in terms of supporting biodiversity, the impact of urban green roofs on biodiversity is still not well understood. Additionally, green roofs play a role in regulating urban ambient temperatures, thereby enhancing the efficiency of solar panels by creating favourable conditions for energy production. There is a compelling correlation between the performance of photovoltaic panels (PV) and the negative impacts of rising ambient temperatures in their vicinity. What may come as a surprise to some is that as surfaces of solar panels heat up beyond 25°C, panel efficiency decreases. Green roofs have the potential to lower ambient temperatures around solar panels through evapotranspiration, thereby maximising the power output of PV systems.
