Centralized sensing platforms for demand control ventilation significantly optimize outside air quantities in buildings and improve occupant safety. Centralized sensing platforms use tubing to transport air samples back to one sensor (e.g. CO2), or a common set of sensors (e.g., CO2, TVOC, Particles, Dew Point, CO). Simply stated, maintaining one sensor, or one set of sensors, is much easier and significantly less costly than maintaining 30-60 or more discrete sensors throughout multiple rooms. With a centralized platform, sensors stay accurate through regular calibration; they are simply swapped out every six months as part of an annual service program. If sensors are being relied upon for control decisions, they must stay accurate – or chances are you will waste energy. A centralized sensing platform provides a far more practical and affordable solution.
In laboratory buildings, 50-70% of energy costs are related to heating, cooling, and distributing 100% outside air. Along with improved lab DCV solutions, significant changes in lab guidelines and standards allow for both deep energy reductions and improved lab safety and operations2.
