The University of Derby is making significant steps to reducing its impact on the environment with the installation of M2G boiler load optimisation controls
Sabien Technology’s M2G intelligent boiler load optimisers have been installed across the University of Derby’s campus following a successful pilot of M2G at the Kedleston Road site. The pilot resulted in a reduction in carbon emissions of 19 tonnes per annum – with a payback of 26 weeks.
“Trying to find ways of saving energy and carbon emissions is a large part of my job and for the cost involved in installing M2G with the resulting short payback, there really was no alternative. Because not all boilers were compatible, we are able to compare the efficiency savings between those with M2G and those without. This has confirmed that M2G has reduced the university’s carbon emissions” explained Energy Officer, Anne Downes.
M2G was installed within 7 campus buildings in the University’s estate, integrating with the existing Building Management Systems and delivering additional energy consumption savings and CO2 emission reductions.
What is M2G?
The M2G is an intelligent boiler load optimisation controller that improves the efficiency of each individual boiler. One M2G is required per boiler, and each M2G is wired into the boiler’s thermostat to reference its set point – this does not override or change the set points. Two digital probes are fitted to the boilers flow and return pipe work. No system drain down is required.
The M2G’s digital probes record the flow and return temperatures every 10 seconds.
The M2G analyses the temperature differential over time. This enables the M2G to identify ‘dry cycling’ i.e. the boiler trying to fire to recover its own heat losses. If a genuine heating demand is made the M2G will identify this and allow the boiler to fire – ensuring ambient temperatures within the building are not compromised.
“Once we had seen the savings possible from the pilot project, the survey to identify compatible boilers was quickly and efficiently carried out. M2G was installed with a minimum of disruption and the units are unobtrusively working away in the background saving the university energy and money. ” Anne Downes concluded.
“The University of Derby’s project demonstrates M2G’s application across different sectors and building types and the significant energy consumption reductions which can be achieved” commented Sabien’s CEO Alan O’Brien. “We work closely with all stakeholders during the installation of our technology, enabling smooth delivery within time and budget. With increasing energy legislation and the need to reduce costs increasing pressure is being placed on organisations to improve their energy efficiency. M2G is now recognised as pivotal technology to deliver these objectives.”
