NHS energy efficiency improvements

Case study: NHS use real-time monitoring solutions to improve performance

Sometimes it’s the simple things … our real-time monitoring solutions helped diagnose training issues that were affecting the performance of an NHS hospital’s energy efficiency equipment.


NHS hospitals rely on a sound infrastructure to deliver critical services. Given the high demand for heating and hot water, maximising equipment performance is vital. With the UK Government’s target of a 34% carbon reduction across hospital estates by 2020 a key consideration, the NHS and their partners are seeking new ways to improve their steam boiler equipment. This is where we were able to help.


Working with an industrial steam equipment supplier and the NHS, we deployed our real-time monitoring solution throughout an energy recovery system used to pre-heat feed and heating water using waste exhaust gases.

Once installed our equipment sensors ran successfully for several months, building up a valuable data set of system performance and operating parameters.


However, the equipment being monitored suddenly began to experience outages, leading to a reduction in overall system performance and efficiency.  Working with the facilities management team at the site our partner was able to access the data collected by our equipment sensors and focus on the specific outages causing the problems.  This enabled the root cause to be diagnosed as operator error.  A misunderstanding during the training of a new maintenance team had been causing the system to be shut down unintentionally. Our partner reported this back to the Facilities Maintenance team enabling them to update their operator training procedures. Once the revised training was delivered operatives restored the system and the problematic outages stopped.

In any complex system with multiple equipment providers and operatives carrying out maintenance, correctly identifying and logging faults and outages is critical in resolving failures. With multiple parties involved the wealth of data made available through DCO Systems equipment sensors and DiscoverRA monitoring solution enabled everyone to agree on the nature of the fault, to isolate the root cause and resolve the issue.
