University of Derby reduce energy costs and carbon emissions with Sabien’s M2G
Sabien Technology’s M2G intelligent boiler load optimisers have been installed across the campus of the University of Derby, following an initial pilot that delivered a payback of just 26 weeks while reducing carbon emissions by 19 tonnes per annum. The M2G units have now been installed in a further six buildings and integrated with the existing building management systems.
“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”, explained the University’s Energy Officer, Anne Downes.
The M2G is fitted to each boiler, typically taking under two hours to install. Installation is non intrusive, requiring no system drain down and is completed during normal business hours. M2G references the boiler’s thermostat but will not alter the set point resulting in no impacts to ambient temperatures. An additional benefit is M2G’s ability to adapt to variable set points via BMS or weather compensation controls.
Digital probes are fitted to the flow and return pipe work of each boiler to record and analyse the flow and return temperatures enabling M2G to differentiate between a genuine call for heat and dry cycling. Dry cycling occurs when boilers fire to compensate for standing heat losses without contributing heat to space heating or hot water systems.
“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 added.
M2G is listed on the Carbon Trust’s Energy Technology List, verified by the EU’s ETV and is approved for London’s Green500 initiative.
