Update on our LED lighting project: highly efficient technology set to save us £115,000 a year
In summer 2023 we shared news of an exciting sustainability project at University Hospital Lewisham - the plan to replace 3000 existing lights with energy saving LED versions.
With work set to take place over the course of a year, we’re happy to report that the team has already made huge progress at the half way stage. Taking our Neonatal Intensive Care Unit in the green zone as a brilliant example of the work done so far, where the team have replaced 121 lights - taking the savings already made and those projected for the rest of 2024 - this one area alone will save us an amazing £19,700 per year on energy.
Gary Singh, the project manager, says: “LED is a highly efficient technology and uses 50% less energy on average compared to a standard fluorescent bulbs. LED smart technology is also able to turn off and dim the lights when presence is not detected. Over the course of a year these bulbs are estimated to save us over £115,000 – and over the 12 year lifespan of the bulbs almost £1.5 million - with carbon savings of 107 tonnes per year / 1,284 tonnes over the projects lifetime.
“We can also target and repair any faults very easily and monitor our energy consumption remotely. Thank you to all of our colleagues who have helped us to get this work done so efficiently and those who have been understanding throughout any disruptions.”
New, more energy efficient ‘chillers’ are projected to make big savings
Equans are our PFI provider for delivering technical and energy services to the Riverside Building at University Hospital Lewisham. In summer 2023 they installed two brand new ‘chillers’ – these systems provide the chilled water that feeds the cooling coil within the air handling unit and the fan coils which are cooling our operating theatres.
The old chillers had an EER (Energy Efficiency Ratio) of 2.6 and the new chillers have an EER of 3.33 - so a huge 47% improvement in terms of direct performance.
The energy and carbon savings for the last six months was approximately: 179,918kWh and 40.48t CO2 (carbon dioxide) respectively. This equates to roughly £36,000 of financial savings for LGT as we are responsible for energy and utility payments.
Robin Fernando, LGT Sustainability Manager said: “This was a really significant piece of work and certainly not an easy project to deliver, so we want to give a huge thank everyone involved. It’s a great example of the way sustainability is now integral to day-to-day operations across our Trust and how we can make an really noticeable difference. We’re all really pleased with the outcome and, as you will see, this is just one of the current work-streams we have in place relating to energy efficiency and cost savings.”
New cardboard balers are already making us savings
New ‘cardboard balers’ have now been installed at both UHL and QEH. They are projected to save us around £30,000 a year!
We currently create around 360 tonnes of cardboard waste a year as a Trust and these machines will compress it down into much smaller, more manageable bundles.
These are not only much easier to store, but when the cardboard is then transferred to a recycling centres it takes far fewer collections – meaning a lot less vehicles travelling to/from our sites and a reduction of our carbon footprint by 10 tonnes of CO2e (carbon dioxide equivalent) a year!
Our previous, daily, collections of cardboard used to generate 15.71 tonnes of CO2e a year and with these monthly collections we will only generate 5.26 tonnes.
Maria Chavarria, Sustainability and Waste Manager, ISS, says: "As you can imagine reducing the number of large vehicles collecting carboard from daily visits, to one a month, will have a huge impact on our carbon footprint. We’re very excited about the financial savings and the sustainability aspects of this project."
Our Bladder, Bowel and Pelvic Health team had a truly incredible 2023
Among some very well-deserved, award-winning recognition, they have also made an astounding £100,000 worth of savings!
The savings were made on containment products (commonly known as continence pads) by ensuring all patients get a relevant assessment and treatment plan to make sure they’re not being prescribed products at the wrong times.
As well as the financial aspects there is also a significant environmental saving as these products go to landfill and are packed with microplastics, taking 500 years to decompose!
Myra Robson, Clinical Lead - Bladder, Bowel and Pelvic Health Service said: “Quite often, pads have been used as a first line treatment - which is not best practice and can reduce the chances that the patient gets the care they need to improve or cure their symptoms. These financial savings go hand-in-hand with a very important environmental saving so it really is a win-win!
“This work was part of a huge team effort. Colleagues reviewed existing patient lists, redesigned the product service and established team-wide clinical pathways, training and processes. We appointed a member of the team to lead on the patient assessments once they reached the stage of needing products. They are then carefully reviewed and it is ensured that appropriate prescriptions are made. The service has received lots of attention and we have been honoured to present our work at three international events in the past 18 months.”
Statistics show that one in three women and one in ten men will experience urinary incontinence, with one in ten men and women experiencing bowel incontinence. It takes an average of six years for a woman with urinary incontinence to seek help and only 25% ever do! One study showed that 50% of people will mention incontinence to a health care professional and if that consultation does not go well then they never mention it again.
Myra added: “We want to reduce the barriers to accessing help, make those conversations easier, and support our patients to access top quality, evidence-based treatment to reduce or eliminate their symptoms. Reducing inappropriate and unnecessary pad use is one way to help us to do that and we have lots of plans for the future!”
Sustainability and our operating theatres
After the launch of our Trust ‘Green Plan’, our Theatres and Anaesthetics teams decided to focus some time and attention on sustainability. They looked at how they could make their day-to-day practices, and work spaces, more environmentally friendly and save money at the same time.
Imran Sharieff, Speciality Doctor in Anaesthesia, said: “We looked at how we could be more sustainable in all aspects of our work. Things we’re implementing and discussing currently include:
- We produce a high amount of PVC plastic waste (found in disposable medical devices, surgical masks etc) and we are looking at how this could be recycled more efficiently
- We have stopped using desflurane and are trying to reduce the use of nitrous oxide, gases used in anaesthetics that are harmful to the environment
- Breaking down cardboard and other packaging and using the correct recycling streams
- Bagging and disposing of waste more efficiently.
“We are looking into reusable metal medical devices to replace single use devices, and consulting with our infection prevention and control colleagues to ensure patient and staff safety is never compromised as a result of our sustainability measures. As well as these actions being beneficial to the environment, they will also hopefully save a lot of money for the Trust."
Other news
With our partners ISS we introduced new recycling bins across our two hospital sites and removed single use plastics from our restaurants.
We have put training in place to raise awareness of the most efficient ways to deal with waste.
We have invested in new secure cycle storage for staff to encourage clean, active travel.
We carried out a water saving programme in collaboration with Thames Water to fix leaks across both hospital sites, which has helped reduce wasted consumption.
By switching to e-payslips (in January 2022) we make huge savings in paper, printing and postage costs.
We have worked with ISS to take action to reduce the carbon footprint associated with food by reducing waste, ensuring that plant-based options are always available and recycling any unavoidable waste
In partnership with the Royal Horticultural Society we have opened our wellbeing garden at University Hospital Lewisham. The garden, as well as helping staff, patients and visitors combat stress, fatigue, anxiety and depression, will also help to improve air quality for our local community.
