Military training school installs over a hundred boiler-load optimisers
A 12% reduction in energy consumption is expected at a military training school following the installation of over a hundred Sabien M2G intelligent boiler-load optimisers. The return on investment is within 1.4 years. HMS Sultan is the home of the Defence School of Marine Engineering and the Royal Naval Air Engineering & Survival School.
The M2G units, 111 of them, were installed as part of a wider-ranging programme of energy-conservation measures carried out by facilities-management company Babcock International. Overall cost savings of over £2 million have been achieved.
Glenn Chatwood, environment and energy manager, explains, ‘Initially we evaluated the performance of M2G on the three boilers in the JRAC building, as these had high gas consumption. Once these results had proved the savings, we rolled the solution out to the remaining 108 boilers on the HMS Sultan estate.’
The evaluation involved comparing gas consumption for four months after installation with data for 12 months before installation, correcting results using degree-day data.
Across the estate, the savings amount to £126 000 a year and 1000 t of CO2 emissions.
The day-to-day management of the project was entrusted to Sabien.
M2G integrates and complements any building-management system, including controls such as weather compensation, boiler sequencing and optimum start. By fine tuning each boiler to address boiler dry cycling, M2G delivers additional cost savings and carbon reductions over and above existing building and boiler controls.
