Making Light Work of Sustainability

Working in collaboration with Cape (Electrical & Mechanical), Ellmer has successfully procured the use of microwave sensors within the temporary LED lighting package at the Kingsway Hall Hotel project.

There are many advantages to using microwave sensors over traditional head-end controlled and passive infrared sensor (PIR) temporary lighting systems. Crucially, the sensors deliver an overall saving despite a higher upfront cost, this is achieved through a significant reduction in energy consumption. The reduction in energy consumption directly corresponds to a decrease in carbon emissions and is additional to the savings already achieved using LED.

Based on occupancy estimates this innovation will save 15,515 kg of carbon emissions over the course of the project when compared with head-end controlled equivalent lighting. This is equivalent to the carbon dioxide sequestered by 257 tree seedlings grown for 10 years (https://www.epa.gov/).

The system works by emitting a low intensity microwave signal and measuring the rebound or ‘echo’ time, which is then used to calculate the distance from stationary objects and establish a baseline measurement. Any movement within the motion detector’s field of view alters the echo time thereby triggering the lighting unit.

The use of the microwave lighting system embodies Ellmer and Cape’s commitment to sustainable business by producing a ‘win-win’ from both a cost and carbon perspective.
