This document discusses new solutions for controlling outside air to reduce energy usage and carbon footprint while maintaining indoor air quality. It describes multiplexed sensing technology that routes air samples from multiple locations to central sensors, allowing accurate differential measurement and dynamic control of ventilation. Case studies show this approach improved energy efficiency in buildings while keeping indoor pollutant levels low.
