Decarbonising healthcare for a Net Zero future
THE ASPIRATION
Cutting carbon, powering care
The NHS has set ambitious targets for Net Zero emissions by 2040, aiming for an 80% reduction by 2028 – 2032. To support this vision, the Trust identified five energy-intensive buildings for decarbonisation: the Academy Building, Undergraduate Medical School at the Royal Stoke site, Linen Store and Clinical Sterile Services Department. The challenge was to cut emissions without compromising operational efficiency, with heat pump technology as the cornerstone of this transition.
OUR RESPONSE
Multidisciplinary Ridge team managed decarbonisation
Our multidisciplinary team partnered with the NHS Trust and maintenance staff to drive the decarbonisation. We delivered integrated solutions across Architecture, Building Services Engineering, Project Management, and Cost Management, focusing on replacing outdated gas boilers with efficient air-to-water heat pumps.
For the Clinical Sterile Services Department, we designed a system using electric boilers to produce circa 165°C steam for the sterilising equipment, located just 20m from where it is needed. Previously, steam was generated 0.5 miles away and piped to the site, with condensate pumped back the same distance – an inefficient process now eliminated.
By carefully analysing each building’s heating systems, we minimised disruption and fine-tuned operating temperatures, making only minor adjustments to integrate the new technology. We also provided planning, structural and acoustic expertise, acting as a one-stop-shop for the Trust’s decarbonisation needs.
THE RESULT
Carbon savings, energy gains
The project delivered significant carbon savings and energy efficiency improvements across key NHS facilities. By replacing 1.8MW of gas-fired heating with modern heat pumps, the Trust reduced its reliance on fossil fuels, cutting gas consumption by 1,600 MWh annually and aligning with the NHS’s Net Zero strategy. The result was sustainable healthcare services with uncompromised building performance.
THE LASTING IMPACT
A future-ready NHS
The upgraded systems now deliver a resilient, energy-efficient infrastructure that balances operational excellence with environmental responsibility. Our holistic approach not only streamlined delivery but also set the stage for wider decarbonisation across the NHS estate.
