Sidney Sussex College cuts energy costs with M2G boiler controls
Sidney Sussex College was founded on St. Valentine's Day in 1596 by legacy of Lady Frances Sidney, Countess of Sussex. The College is located in the historic heart of Cambridge. Sidney Sussex College installed M2G boiler load optimisation controls across its estate after seeing a 17% reduction in its oil consumption.
The College initially installed M2G in one boiler house to verify the level of savings. Energy consumption data was provided to Sabien which was then analysed to establish the level of energy savings using the CuSUM methodology. The analysis demonstrated a 17% reduction in oil consumption. The graph below illustrates the impact M2G had to oil consumption.

Following the analysis the College proceeded to installed M2G on the remaining 11 boilers. The boilers varied in age and size and there was no downtime to the College’s operations during the installations. Using the 17% savings initially verified, it is estimated the project will payback in 2.1 years, saving the College over £9,500 a year and resulting in avoided CRC costs of over £3,500 over 5 years.
“Reducing our heating consumption and the associated oil costs is a key objective for the College and Sabien’s M2Gs are playing a key role in achieving this. There was minimal disruption to our operations throughout the whole project. Sabien provided complete end to end project management, including the measurement and verification, commissioning and installations of the M2Gs.” said Keith Willox, Domus Bursar for Sidney Sussex College.
What is M2G?
M2G improves the energy efficiency of commercial boiler plant by optimising each individual boiler, delivering real time analysis and control to reduce energy costs. M2G achieves the energy savings by preventing dry cycling, an area of boiler inefficiency long known within the industry but largely ignored. M2G works alongside the existing controls and strategies such as sequencing, weather compensation and demand based control. M2G is widely recognised as a key initiative to reduce energy costs for many Private and Public sector organisations.
