New IoT Radar Occupancy Sensor Assists in Reducing Energy Consumption.

Updated: Aug 22, 2022

IoT Radar Occupancy Sensor

EnviroLogik have recently installed a new unique IoT Radar Occupancy sensor at a Multi-Let London Office in Queen St London, that individually counts people in/out of a Building or Floor.

Because of Hybrid working, like many Commercial Buildings throughout the UK Landlords and Property Management are seeing reduced numbers returning to the office, especially on Mondays and Fridays.

CBRE GWS wanted a way to reduce the Energy being consumed in the building and to correlate the occupancy to the Energy Consumption of HVAC/VRF system.

They needed a simpler more accurate and less expensive solution than having to install individual desk sensors connected to yet another 3rd party system.

One of the key objectives for CBRE is having less individual systems that don't "talk" to each other and ideally aiming for a "single pane of glass" view of all IoT sensors and assets without needing separate systems and logins which is available from MEP specialists EnviroLogik.

The new EnviroLogik Radar based IoT sensors are highly accurate and are installed at either a Buildings entrance/exits or also at the entrance to tenants own areas - or a combination of both. They are the size of a smoke detector and simply need to be mounted above door entry/exit points.

They connect via a private RF LoraWan network to the buildings existing IoT gateway meaning that customers can view everything from a single log-in and Dashboard that was quickly and easily custom created.

To prove and validate the energy consumption vs occupancy, the following screen shows a summary of occupancy at the top and energy consumption below.

As can clearly be shown from the graph is that Energy consumption is high even on days with low occupancy, which means that the HVAC systems need to be adjusted to suit the actual occupancy

Additionally either the full building or tenants remote energy consumption can be achieved with either direct meter readings or via local CT's. Where there are older analogue meters, these can be remotely read via special meter limpet attachments meaning that any meter of any type or make can be remotely read.

This helps to validate the actual consumption and cost

This system is now being used to help Businesses achieve energy reductions and net zero.
