ventit

Ventit is a hypothetical open standard and ecosystem for intelligent ventilation control in built environments. It defines a modular data model, communication protocol, and reference implementations to integrate sensors, actuators, and building management systems (BMS) for optimized indoor air quality and energy efficiency.

Etymology: The name Ventit is a portmanteau of vent, referring to ventilation, and -it, suggesting interconnection and simplicity.

Overview: The Ventit specification covers data schemas for air quality (CO2, PM2.5, VOCs), occupancy, and environmental parameters; secure, interoperable APIs; and basic control policies for demand-controlled ventilation and outdoor air intake. It separates the logical control layer from hardware specifics to encourage vendor neutrality.

Architecture: The core consists of Ventit Core, which provides the data model and policy engine, Ventit Agents that run on edge devices or gateways, and Ventit Modules for common equipment (fans, dampers, AHUs). A Ventit Registry tracks compliant devices and services.

Applications: In commercial buildings, Ventit enables dynamic ventilation strategies, improves energy performance, and supports health-based guidelines. In schools and hospitals, it can help maintain air quality during occupancy fluctuations. It is designed to interoperate with existing BMS, IoT platforms, and cloud analytics.

Standards and adoption: Ventit is described in a series of technical white papers and reference implementations published by a collaborative, but fictional, open consortium. Real-world adoption depends on regulatory alignment, data privacy, and interoperability testing.
