Revolutionizing building management: How Time-of-Flight people counting optimizes energy usage

Reducing the energy consumption of buildings is vital for both environmental and economic reasons. What technology is available for facilities managers?

Buildings consume 30% of global energy

According to the International Energy Agency (IEA), energy use in buildings increased from 115 EJ (exajoules) in 2010 to nearly 135 EJ in 2021, representing 30% of global final energy consumption. If the final energy use associated with the production of cement, steel and aluminium is added, the share increases to 34%.

Time-of-Flight (ToF) people counting is a technology that utilizes sensors to detect the movement of people in a specific area. This technology is increasingly being used in buildings to improve energy efficiency by controlling lighting, heating, and ventilation based on the number of occupants in a room or space. In this article, we will discuss the benefits of ToF people counting for energy efficiencies in buildings.

Why use Time-of-Flight people counting?

Firstly, the data from Time-of-Flight people counting technology can be used to reduce energy consumption by automatically adjusting lighting levels based on the number of people present in a room or a designated space. For example, when a room is empty, the lights can be turned off automatically, saving energy. 

Secondly, ToF people counting technology can also give occupancy data that can be used to control heating and ventilation systems in a building. By monitoring the number of occupants in a room or space, the heating and ventilation systems can be adjusted to maintain a comfortable temperature while minimizing energy usage. This can lead to significant energy savings, particularly in larger buildings. 

Finally, ToF people counting technology can also help to improve the overall comfort and well-being of building occupants. By controlling lighting, heating, and ventilation systems based on occupancy levels, building managers can ensure that occupants are comfortable and productive, leading to improved user satisfaction and better outcomes.

Time-of-Flight technology, a non-intrusive solution

Time-of-Flight technology is non-intrusive and does not gather personal data. Unlike some traditional methods of people counting, such as CCTV or facial recognition, ToF technology does not rely on cameras or other sensors that may capture identifiable information.

ToF technology simply measures the distance between objects and uses this information to determine the number of individuals passing through a specific area. So no personal data is ever collected or stored, and individuals are free to move through the monitored area without fear of being tracked or monitored.   

Furthermore, the data gathered by Terabee Time-of-Flight people counters doesn’t measure the height of the person coming into the counting area. Instead it relies on seeing points for head and shoulders to indicate a person has passed into or out of the area.

Anonymous, accurate people counters from Terabee

Another important aspect of People Counting solutions from Terabee is that they only gather anonymous data. Terabee people counters are fully GDPR compliant. With its ability to aggregate data taken from up to five separate sensors, the Terabee People Counting L-XL offers an easy to install and configure, highly accurate doorway counter for monitoring large doors, entrances and indoor gates. The Terabee People Counting M device is suitable for standard doors and narrow corridors. Tailor your people counting solution and system according to your requirements. Both solutions come in LoRa-enabled models.

In conclusion, ToF people counting technology offers numerous benefits for improving energy efficiencies in buildings. By automatically adjusting lighting, heating, and ventilation systems based on occupancy levels, building managers can reduce energy consumption, improve occupant comfort and well-being, and achieve significant cost savings. As such, it is a technology that should be seriously considered by anyone looking to improve the sustainability and energy performance of their building.
