needsair

needsair is a modular, open-source platform designed to monitor, analyze, and address air quality needs in built environments and urban spaces. The project combines sensor networks, data processing, and decision-support tools to help users optimize ventilation, filtration, and related interventions to sustain healthy air quality.

Origin and scope: needsair was launched by a community of researchers, engineers, and practitioners in response to growing concerns about indoor air quality and the transmission of airborne pollutants. It emphasizes openness, interoperability, and user-driven development rather than proprietary control.

Architecture and features: needsair provides a modular architecture with sensor adapters, data normalization, a time-series store, dashboards, alerts, and an AI-assisted recommendation engine. It supports open data formats, REST APIs, and can integrate with building management systems and occupancy models to tailor ventilation strategies.

Adoption and impact: The platform has been implemented in schools, offices, hospitals, and municipal facilities to monitor IAQ indices, guide ventilation and filtration, and optimize energy use. Reported outcomes include improved air quality metrics and more consistent compliance with air-quality standards.

Governance and licensing: needsair is distributed under an open-source license and governed by a community council with inputs from contributors. Data handling emphasizes privacy and ownership, with opt-in data sharing and clear guidance on localization and compliance.

Limitations and reception: Success depends on sensor coverage, calibration, and data quality. Costs and maintenance pose barriers for some organizations, and ongoing work focuses on standardizing metrics and ensuring robust interoperability.
