The challenge – HVAC use optimization in university lecture halls<\/h1>\n

Feedback Solutions<\/strong>, a solution provider that accelerates decarbonization initiatives and helps businesses reduce utility costs with its data-driven software to optimize HVAC systems, was approached for a project to reduce HVAC-related energy consumption in a large university in the United States.<\/p>\n

The university sought insights on the number of people entering and leaving lecture halls, in order to use accurate, real-time occupancy data to ventilate buildings. Feedback Solutions uses a proprietary occupancy calculation algorithm that enables real-time control of ventilation in buildings.<\/p>\n

The company is also part of the Net Zero Accelerator<\/strong> (NZA), from the U.S. Green Building Council\u2013Los Angeles<\/strong> (USGBC-LA). The Net Zero Accelerator focuses on pilot projects in real-world, trackable implementations, to drive adoption of net zero solutions.<\/p>\n

The solution<\/h2>\n

Terabee answered the call, with its People Counting L-XL<\/strong> device, which is GDPR compliant<\/strong> by design as it uses Time-of-Flight non-camera technology. Two Terabee People Counting L-XL devices were installed in each lecture hall entrance to capture the movement of people in and out of the spaces.<\/p>\n

\"People-Counting\"<\/p>\n

Almost 2,700 m2 (29,000 ft\u00b2) of lecture halls were covered using Terabee and other sensors, with four Terabee People Counting L-XL sensors used to cover two lecture halls for this part of the project. Currently, Feedback Solutions has Terabee sensors deployed across 30 lecture halls in another university building where a similar exercise on energy savings is being done.<\/p>\n

Feedback Solutions used the GDPR-compliant Terabee People Counting XL sensor to capture lecture hall occupancy. Easy to install and configure via a Web GUI, the Terabee sensor offers multi-device support for wide door counting. With its powerful people-counting algorithm People Counting L-XL gives 98% accuracy and it is effective in low-light conditions.<\/p>\n

About the Feedback Solutions approach<\/h2>\n

\"\"<\/p>\n

Feedback Solutions\u2019 software pulls raw data from the installed sensors to calculate real-time, zoned occupant counts and sends the data to the building automation system via BACnet to drive HVAC savings. Feedback Solutions works with their customers\u2019 BMS suppliers to define a new sequence of operations to modulate the fan speeds and damper positions. This supplies the optimal amount of outdoor air based on the actual ventilation requirement.<\/p>\n

The company uses a sensor-agnostic approach to procure best-in-class sensors based on the design criteria of the space. Its software solution enables data aggregation from multiple sources (for example IAQ sensors and people counting sensors) to further optimize the sequence of operations.<\/p>\n
