WWL NHS Trust Saves £8.6m With IoT Lighting

• In the Royal Albert Infirmary alone, the intelligent controls savings are 29,600 kWh for just one month.
• At 30p/kWh, this would save the trust £100k on energy bills over a year and remove more than 65 tonnes of CO2 equivalent emissions from the atmosphere. As this is a rolling project, their carbon and cost savings accumulate with each new area completed.
• 91% of savings are achieved by the lighting being regulated by IoT smart controls – responding to whether an area is vacant or occupied; and utilised to serve areas which have an important function. Additionally, 9% of savings come from the system being able to ‘harvest’ natural daylight.
• The IoT-controlled system constantly optimises the light levels for maximum comfort ­– for both NHS staff and patients. It guarantees that light levels are calibrated to the task at hand. And in more relaxed settings, to levels that feel most natural to the eye.
• As we connect new areas into the Internet of Things (IoT) platform, the trust has an opportunity to unlock further smart building solutions.
• These include trialling asset tracking, gaining access to detailed occupancy and utilisation reports, and additional building services, like heating and cooling; all part of the intelligent building management system.

CILS have an exceptional track record, delivering smart IoT lighting, energy reduction, and smart building projects in a range of environments. In the healthcare setting, delivering results without disruption to hospital staff and patients has been particularly crucial

Over the projects, CILS have built a strong relationship with the Trust – based on proven, measurable energy savings, excellence in Internet of Things (IoT) engineering, and CILS team workmanship.

CILS carry out Lighting Investment Grade Audit (IGA), and produce RIBA stage 4 lighting designs for each project.

Once the lighting is installed, we fine-tune the LED and commission the IoT controls system.

After this, we connect each newly refurbished area into the smart building infrastructure.

In a hospital, lives are on the line 24/7 and emergencies can happen at any time. We are fully aware that access times can be very limited and our site team always prioritise hospital requirements.

For example,

• We install and commission only at specified access hours, be it 4 am or 9 pm. Some areas may only have access for 2hours a week and we plan accordingly.
• We are prepared for the unexpected. There have been times when we’ve packed up everything (cables, tools, etc) in minutes, to prioritise staff access in emergency situations.
• Communication with staff and the future user is always at the core of our approach. We deliver quality results in the limited time we have. Our aim is to ensure our solution serves the needs of the members of staff, as well as the location.
