HVAC sensors and controls to lower energy consumption in buildings

United States. Recent research shows that using advanced controls and sensors for HVAC systems could save up to 20-30% of building energy consumption and while the option is available, most must be wired or are cost prohibitive.

Researchers at the Department of Energy at Oak Ridge National Laboratory (ORNL) are looking to change all that by developing new wireless node sensors with a lower cost of production.

With current wireless node sensors costing up to $150 to $300 per unit, the ORNL team expects their prototype sensor to make the technology more economical, reducing costs by around $10.01 per node, using new construction techniques such as coil-by-coil manufacturing.

Node components are printed on flexible plastic substrates and installed wirelessly with adhesive lining. The sensors provide the most accurate temperature information for the system that is running, allowing you to use energy more intelligently. Smart sensors are designed to work in both new and refurbished buildings, and ORNL is currently looking for a corporate partner to help bring the sensors to market.
