United Lincolnshire Hospitals NHS Trust

Lincolnshire, United Kingdom

United Lincolnshire Hospitals NHS Trust is one of England's biggest acute hospital trusts, serving a local population of 720,000 people. The Trust has worked with sustainability consultant ETL on an Energy Performance Contract (EPC) to procure and appoint an energy supplier. It has installed Thorlux SmartScan standard and emergency luminaires across its main hospital sites – Lincoln County, Grantham Hospital, and Pilgrim Hospital in Boston. The programme aims to build long-term energy resilience and make lasting enhancements to the patient care environment at the three hospitals.

The Challenge

The primary aims of the new lighting scheme were to improve lighting levels and minimise energy usage through Smart controls while providing a safe and comfortable environment for the public and staff. The ULHT expects to cut annual carbon emissions by 7,712 tonnes across the three principal hospitals.

Claire Hall, Associate Director of Strategic Business Planning at ULHT, said, "Sustainability, energy efficiency, and carbon reduction are at the heart of our management policy. We have already made great strides in reducing our carbon footprint. By upgrading and investing in sustainable technologies, it is our ambition to reduce this by 28% by 2021."

The Solution

Thorlux Lighting proposed a new installation combining the necessary energy savings with improved lighting quality throughout the building. The recommendation involved installing the Thorlux SmartScan monitoring and management system with Smart intelligent lighting control. Integral Smart sensors monitor ambient light and presence, control output to the correct level, dim and switch when there is sufficient daylight and illuminate the area only when occupied. Thorlux SmartScan luminaires have delivered a 91% energy saving compared to the previous lighting installation, resulting in electrical operating savings of £398,570 per annum.

Associate Director of Strategic Business Planning Claire Hall said, "The Trust received a grant from the National Energy Efficiency Fund for £2.6 million enabling the replacement of around 12,000 light fittings with modern LED fittings with smart technology. This technology means lights turn off after a period of inactivity, saving energy and money for the Trust."

SmartScan automatically controls the emergency lighting test regime, monitoring the status of each luminaire and reporting daily to the SmartScan website. Smartscan emergency luminaires test according to the schedule specified in BS EN 62034:2012 and display the current status via a bi-colour LED. Users of the SmartScan website can view current status information and complete archival data when required. The hospitals have recognised they can achieve significant savings by removing the task of manually testing thousands of emergency luminaires every month.
