Control Integration Enables New Strategies for Laboratory Room Operation
June 21, 2018
1 p.m. – 2 p.m.
Eastern Daylight Time
Advances in building automation technology bring higher levels of networked control integration which, in turn, enable new strategies to optimize operation of the laboratory infrastructure. An extended control interface between fume hoods and the laboratory room allows new functions. Automation technology can calculate exhaust capacity within the room or the system level and warn the fume hoods and laboratory workers so they can close sashes and maintain function. This technology enhances the reliability of systems designed with a mechanical diversity factor.
As conservation strategies decrease laboratory air flow rates, heating is added to the familiar list of possible air flow drivers (ventilation, make up, and cooling). Some building codes require control systems that can increase air flow to support the heating function.
Merging control systems for lights and daylighting with HVAC systems enables a comprehensive setback strategy when workers are not present. Specifically designed operating modes respond differently when they are not used for a long duration of time (e.g., overnight, over the course of a few weeks). This presentation will review these control integration strategies and demonstrate how they can increase the efficiency of laboratories.
After viewing this presentation, attendees will:
- Implement a comprehensive setback strategy, including heating, cooling, ventilation, and lighting to establish a 'occupant-responsive building.’
- Apply engaging, effective interfaces for laboratory users to make them 'building-aware occupants.’
- Select and apply enhanced interfaces between hood controls and the laboratory room.
- Connect air flow controls in rooms and hoods with central fan systems for efficient operation.
