Intelligent ventilation system based on passive air renewal mechanisms, complemented by automated components. Specifically, the project proposes the design and implementation of a control system that automatically regulates the opening and closing of windows, guided by key variables such as indoor CO₂ concentration, indoor temperature, and outdoor weather conditions (temperature, humidity, wind, among others). This approach aims to improve indoor air quality efficiently and sustainably, contributing to thermal comfort and occupant well-being while minimizing the use of energy resources.
