Airflow & Airwaves: Segmenting HVAC and OT to Keep Buildings Running

When heating, ventilation, and other operational systems share networks with IT and tenant services, a single fault can cascade into a tenant-facing outage. In this episode Alex Morgan interviews Michael Harrington about practical approaches to segmenting HVAC and other OT systems so owners and operators reduce operational risk, simplify troubleshooting, and assign clear responsibilities after project closeout. We walk through why segmentation matters for uptime and safety, tradeoffs between strict isolation and managed connectivity, and pragmatic steps teams can take during design, renovation, or vendor handover. Michael brings real-world examples from multi-tenant and mission-critical facilities, explaining how modest architecture changes and clarified vendor scopes avoid costly downtime. Listeners will come away with concrete decisions to make at planning and procurement stages, and realistic expectations for costs and operational impacts.
