Systems and methods for air remediation

Abstract

Systems, methods, and apparatus are provided for monitoring and improving air quality in single- and multi-zone indoor spaces. The system for monitoring and improving air quality includes a built structure that includes an indoor space with environmentally-controllable zones, an environmental control system, sensor arrays positioned within the environmentally-controllable zones, and a control circuit configured to monitor air and remediate air within the indoor space. Multiple zones in the indoor space may be bundled together in multiple remediation bundled-areas for remediation by separate air handling systems and/or processes. Additionally, multiple zones may be delineated within the indoor space for sensor installation processes.
