Abstract
The paper presents the efficiency project that Enerbrain collaborated on in 2024 to upgrade the heating control systems of nine Long Term Care facilities in France. The retrofit consisted of an IoT-based solution integrating local controllers with a cloud-based control algorithm, aiming to implement BACS class B control functions within legacy heating systems. The results of this study demonstrate that these retrofit actions led to an average 29% reduction in heating energy use intensity and provide interesting insights on how to perform energy savings assessments taking into account the actual complexity of facility management activities in tertiary buildings.
