Integrate Lighting, Daylighting and HVAC Control in the Laboratory Room

Jim Coogan, Siemens

New developments in Room Automation bring lighting controls and automated shading together with HVAC. The result is a room that is integrated for energy efficiency, responsive to demands of occupants, and more cost effective to construct than separate control systems.

Even newer developments bring that paradigm to the laboratory environment, where critical ventilation functions coexist with comfort considerations and energy conservation. In operation, occupancy data is shared at the room level between systems so that temperature settings, ventilation, light levels and shade position can be coordinated in a comprehensive setback strategy.

Room occupants can positively influence building performance, interacting through a single interface that combines HVAC, lighting and shading functions. The fume hood operator's panel applies the same UI concepts, giving the whole system uniform, logical feel.

Learning Objectives

  • Identify the variety of ways that lab workers influence energy consumption in a facility
  • Learn to specify the most basic level of integrated lab room automation, connecting thermal comfort, ventilation for exposure control, lighting and daylighting.
  • Recognize the physical connections and distinctions between different aspects of room infrastructure, HVAC, lighting, and daylighting.
  • Engage all categories of lab building users (operators, energy managers, EHS officers, lab managers and scientists) in efficient, effective operation of the facility.
