DIGITAL TECHNOLOGY
standard day, we integrated time clocks that would automatically shut off systems at those times. Just making this change led to immediate reductions in energy consumption on site.” In addition, the local controllers on AC
systems around the site were limited to +3 and -3 degrees Celsius from a setpoint temperature. Previously, this wasn’t possible, as the hospital lacked a central point of control for the AC systems. With data and control now readily available in the IQVISION BMS, MKUH could have greater control over AC-related energy consumption. Similarly, the humidity and CO2
data from the Haltian sensors were
used to inform the ventilation control over specific rooms throughout the ward. The impact on energy consumption
across the site was striking. Within a few months of the project being completed, the site team at MKUH saw a consistent 40% reduction in energy consumption. This comes at a time when hospitals were braced for a 200% increase in energy costs. “Knowing now how we can use digital
technology to improve patient care and support effective estate management decision-making puts us in a good position ahead of the development of our new Women’s and Children Hospital,” concludes Rebecca Grindley. “There is still work to be done to ensure seamless

integration is achieved and felt by occupying staff. However, we have been impressed with the progress, and believe the insight this collaborative piece of work has given us will play a huge part in how we use digital technology to improve our estate infrastructure and provide facilities fit for the future for both patients and staff.”
