Presentation

The Falcão Elementary School served as a pilot building to receive a set of nature-based solutions specially designed and created to increase indoor bioclimatic comfort and, at the same time, boost resilience to climate change. The main solutions implemented were: three green roofs, a green wall and a pond. These solutions were complemented by the installation of photovoltaic panels to produce green electricity for self-consumption.

The green roofs were studied and analysed by the Associação Nacional de Coberturas Verdes (National Green Roof Association) as part of the Projeto Quinto Alçado do Porto (PQAP), whose main objective was to define a strategic model for integrating green roofs into the environmental and urban strategy of the city of Porto.

The interventions were carried out as part of the My Building is Green (mBiG) project. This project consists of adapting school and social service buildings to climate change in three very different climatic regions (Porto and Alentejo in Portugal and Badajoz in Spain).

Results

Increase of 168.94% in green areas, totalling 1,076.94 m2;
Installation of a 28 m2 natural pond that serves as a biodiversity reservoir (amphibians, aquatic macro-invertebrates) and constitutes a living educational resource;
Roof temperatures 5.4 °C lower after NBS implementation;
Reduction in rainwater loss from 30 per cent to 3.74 per cent;
Increase of 26 new species, mainly flying insects, flies, mosquitoes, hymenoptera and some species of the Armadillium genus, which are indicators of habitat quality;
Annual production of 28,625 kWh of photovoltaic energy

Emissions reduction

Reduction of 7.39 tonnes of CO2 per year (only by photovoltaic energy consumption)

OTHER SUGGESTIONS

The historic building, which was in a state of disrepair, was rehabilitated taking into account sustainable construction practices, incorporating two green roofs and energy efficiency improvements that enabled it to obtain LEED (Leadership in Energy and Environmental Design) certification.
The Campanhã Intermodal Terminal (TIC) has the largest green roof in the city, which helps to absorb all the air and visual pollution from the terminal. It was the first public building in the country to achieve the LEED (Leadership in Energy and Environmental Design) level of environmental certification in 2025.
