Modelling the potential of green roof installation for the decarbonisation of urban areas. Case study of Valencia, Spain
The transition towards sustainable cities faces complex challenges, and nature-based solutions, such as green roofs, are emerging as an innovative response. In this context, the Master’s Thesis by Tomás Pino Gallardo, entitled ‘Modelling the potential of green roof installation for the decarbonisation of urban areas. Case study of Valencia, Spain’, presents an innovative methodology to identify the potential for installing green roofs in Valencia, addressing their environmental, energy and urban impact.
Under the direction of Paula Bastida Molina and Tomás Gómez Navarro, this project combines computer vision, LiDAR technology and geospatial analysis with tools such as MATLAB and QGIS. The methodology developed identifies the optimal areas for the implementation of green roofs, considering factors such as roof inclination, orientation and cadastral characteristics. This approach makes it possible to generate georeferenced maps that delimit the surfaces suitable for intervention.
Main results
The study revealed a potential of approximately 625 hectares of roofs susceptible to transformation, which is equivalent to 22,559 buildings with green roofs in Valencia. This translates into:
- Reduction of CO2 emissions: 52,219 tonnes mitigated annually.
- Energy savings: Reduction of 162 GWh per year, significantly decreasing energy consumption for air conditioning.
- Environmental impact: Improvement of thermal comfort and mitigation of the urban heat island effect.
The methodology also considers the carbon capture by the vegetation used on the roofs, providing key data for strategic decisions in urban planning.
Innovation and replicability
Unlike traditional approaches, this model combines advanced technology with a high level of automation, making its large-scale application in other cities viable. The maps generated allow urban managers to identify priority areas, maximising the impact of interventions.
Social and environmental benefits
In addition to the environmental benefits, green roofs improve the quality of urban life by providing green spaces in densely populated areas. This encourages biodiversity, reduces noise pollution and contributes to the physical and mental well-being of citizens.
The work of Tomás Pino Gallardo stands out as an example of how technological innovation can be integrated with sustainable strategies to transform our cities. His proposal is not only a contribution to academic advancement, but also a practical tool for achieving the European Union’s climate goals and the 2030 Agenda. This project reaffirms the Universitat Politècnica de València’s commitment to applied research and urban sustainability.
