THE NATIONAL Health Service is experimenting with Internet-connected lights to track equipment and the occupancy of its buildings.

The trial at Wrightington, Wigan and Leigh NHS Foundation Trust – which manages five public healthcare facilities located in Manchester, UK –  consists of 612 LED luminaires with featuring ‘Internet of Things’ smart sensors, which have replaced 904 fixtures.

The sensors – from US firm Enlighted –  build an ‘IoT sensory system’ and detect a variety of activities inside the hospital from motion to occupancy, temperature, ambient light, energy consumption and the movement of assets. Cloud-based software then translates the data into actionable insights that the hospital can use to help make the building smart, safer and more efficient while improving the overall patient and staff experience. 

Enlighted’s apps include visualisations providing heat mapping, motion trails, motion animation, time series and more. 

As well as energy saving and space optimisation, predictive maintenance can take place onsite or offsite. 

Assets like hospital beds and ventilators can be located in real time, ensuring more time is spent with patients rather than searching for equipment.

Enlighted’s apps include several visualisations providing heat mapping, motion trails, motion animation, time series and more. 

In addition, reports are generated on different sections of the centre to measure utilisation, occupancy and vacancy. 

The Space application and the Where application, featuring real-time location services, are two cases where the advanced data analytics can address current challenges, including space utilisation and location of assets as well as other possible virus and disease outbreaks post-Covid.

The project’s estimated cost savings are £38,000 annually with a four-year return on investment. 

Time savings and increased productivity are also expected from enhanced asset management in the hospital. 

By capturing occupancy data, the NHS can optimise hospital space in an agile way, especially during Covid with physical distancing regulations, saving energy and lowering operating costs. 

A report is generated by each of the lighting fixtures giving details on light output, temperature, light level and more, helping with operation and maintenance cost optimisation.

The installation of the smart sensor network is part of the NHS’s operation-wide Carbon Management Implementation Plan for energy optimisation was initiated, and the goal was to deliver better custom lighting control and unlock the power of the IoT for healthcare facilities.

NHS installed Expected energy savings include 80-85 per cent compared to the previously installed lighting fixtures, achieved through task tuning, dimming and linger settings, daylight harvesting and motion groups.

Wrightington, Wigan and Leigh NHS Foundation Trust employs about 5,000 staff with 750 inpatient beds and approximately 300,000 outpatients a year.
