Bradford Royal Infirmary
Replacement car park lighting supplied and installed by TCS for Bradford Royal Infirmary has reduced energy usage and cut maintenance costs – without any loss of lighting level.
The teaching hospital had planned to use LED lighting as a replacement, because, as the hospital’s Energy Manager Nsipa Siwale says, “We thought that was the way to go.”
But when TCS Director Dave Clements met with Nsipa, he suggested something completely new to the hospital - and he was prepared to prove it would be more cost-effective and more environmentally friendly.
While lower energy usage was an important requirement of the new lights, it was vital that a good level of illumination be maintained to enable the capture of good quality CCTV images in the busy park.
There were, of course, financial considerations too. The hospital seeks to achieve value for money in all of its activities.
What TCS suggested was that the existing 250w and 450w metal halide flood lights be replaced with 80w induction lights.
To prove that these would more than meet the hospital’s criteria, it was agreed that six induction units be installed on a trial basis.
The trial proved that the desired lighting levels could be achieved while at the same time reducing energy usage and cutting maintenance costs by a considerable margin.
Induction lights have a guaranteed 100,000 hours life, double that of LED units. This means maintenance costs are halved.
Light depreciation is also far more rapid with LED units than with induction lighting – perhaps one of the reasons why they are used on San Francisco’s landmark Golden Gate Bridge.
Money for Bradford Royal Infirmary’s car park lighting came from a Government source which had a list of technology eligible for it. Induction lighting was not included on the list. “I contacted them and made an informal request that induction lighting be included as we had found it to be better than LED,” Nsipa said.
Clearly, Bradford Royal Infirmary is very pleased with the results – and was equally impressed with the installation service provided by TCS.
“The engineers worked around us to minimise disruption,” Nsipa said. “In some areas they waited for times when it was quieter.”
The LED unit used in the comparison trial has been retained in the hospital car park, providing, Nsipa says, an on-going test.
Commenting on the project, Dave Clements said: “We are delighted to have been able to provide Bradford Royal Infirmary with a solution that fits with its sustainable development strategy, delivers a reduced environmental impact and provides excellent value for money.”
