The performance of EndoTherm was piloted by North Staffordshire Combined Healthcare NHS Trust in two phases. Phase 1 saw EndoTherm installed into the Greenfields Centre, an adult community mental health facility.

After a successful Phase 1 pilot, saving 13.68% on space heating energy consumption at Greenfields over 3 months, the trust decided to roll-out EndoTherm across the rest of its gas heated estate.

In Phase 2 a further 21 buildings were dosed with EndoTherm in December 2023.

Healthcare facilities in the UK operate under strict regulatory requirements for indoor environmental quality, including temperature and air circulation standards. These facilities must maintain consistent, comfortable temperatures for patients, many of whom may be vulnerable to temperature fluctuations due to illness or compromised immune systems.

This necessity often results in higher energy consumption compared to other building types. Additionally, healthcare facilities typically operate 24/7, requiring constant heating throughout the year, which significantly increases energy demand and makes it difficult to implement typical energy-saving measures like nighttime setbacks.

Another major challenge lies in the diverse nature of healthcare facility infrastructure across the UK. Many NHS trusts, including North Staffordshire, manage a mix of old and new buildings. Upgrading these systems or retrofitting buildings for better energy performance is often prohibitively expensive and can disrupt critical healthcare services.

Balancing these diverse needs while trying to reduce overall energy consumption presents a significant challenge for facility managers and energy conservation efforts.
