In dense informal settlements around the world, tightly clustered buildings often result in poor ventilation, affecting residents’ health and increasing the risk of airborne diseases.
 
We propose Brisa+, an interactive simulation system that uses minimal spatial interventions to improve community airflow and reduce health risks. It dynamically models building layouts, greenery, and wind corridors to visualize their impacts on urban comfort and well-being.

Brisa+ has been applied in Favela do Vidigal, Rio de Janeiro, helping users understand how small adjustments—such as creating wind paths, adding green spaces, and modifying building heights—can significantly improve ventilation.

Inspired by the “butterfly effect”, tiny design changes can generate profound improvements for urban environments. Brisa+ offers an innovative approach for sustainable urban renewal.

This project was developed in the Tsinghua + MIT Senseable City Lab Joint Workshop, October 2025.
 

项目简介:
在全球城市中，人口密集的非正式社区长期面临建筑紧密排列，空气流通不畅的困境，不仅严重影响居民的生活舒适度与健康，更成为空气传播疾病扩散的潜在隐患。

我们在思考:如何在非正式聚居区，通过干扰性最小却最有效的空间改造，改善气流状况并降低空气传播疾病的传播风险?

这样的背景下，我们设计了交互界面系统Brisa+，动态模拟不同建筑环境布局与植被配置直观展现其对社区环境产生的影响，并解析不同的风环境如何影响居民的健康与舒适度。

Brisa +项目已成功应用于里约热内卢的Favela doVidigal非正式社区。用户借助该系统，能够探索社区中的风环境，并深入了解诸如开辟风廊、增添绿地、调整建筑高度等微小空间干预措施，如何重塑社区的空气流通格局。
正如"蝴蝶效应"所揭示的，一只蝴蝶扇动翅膀可能引发巨大变化，在Brisa+的交互设计探索中，每一个看似细微的设计改动，都可能成为改善社区环境的关键因素。通过 Brisa+，我们期望以创新的交互模拟方式，为城市环境优化与可持续发展提供新的思路与解决方案。
