Passive Strategies for thermal comfort in Amazonian Cities: The Case of Tena's Waterfront

This study explores the application of passive strategies focused on reducing urban heat islands, with special attention to improving pedestrian thermal comfort in Amazonian cities. Based on climatic data such as temperature, humidity, solar radiation, and wind speed, the impact of urban morphology on public space, particularly on the Tena River waterfront, is analyzed. Using the Grasshopper and Ladybug simulation tools, two scenarios were compared: one current, with 2-3 story buildings, and one proposed, which includes buildings up to 6 stories integrated with native vegetation. The results demonstrate that the proposed scenario not only increases shading but also significantly contributes to the reduction of temperatures, confirming the viability of these strategies to enhance sustainable urban design and improve the quality of life in Amazonian environments. The evaluation of the results highlights aspects to improve in urban development and emphasizes the importance of integrating simulation tools to design urban proposals and open spaces, guaranteeing a comfort zone for the user, encouraging pedestrian routes and therefore increasing social relations in nearby public spaces.
