Boiler energy optimisers rolled out at Salford University
A measurement and verification project at the University of Salford has demonstrated that Sabien’s M2G boiler load optimisation controls delivered average fuel savings of 13.5%, with a payback of around seven months. Following these verified savings, M2Gs are being installed across the university’s estate.
This university is one of 33 taking part in the Carbon Trust’s higher-education carbon-management programme. It has already taken a number of measures to reduce energy consumption and carbon emissions and is continually exploring further opportunities.
Matteo Littera, the university’s energy manager, explains, ‘One of the areas we investigated was boiler dry cycling. We were impressed that Sabien validates energy savings in line with the International Performance Measurement & Verification Protocol (IPMVP).
‘We also considered re-configuring the building-management system, but it was clear that this would require many hours of re-programming and could not compete on cost.’
M2Gs were initially installed on 11 Remeha Eco 3002 boilers in three buildings, selected on the basis of being typical of those across the estate.
Energy consumption was compared to previous consumption using degree-data to allow for weather variation. In addition to the 13.5% reduction in boiler gas consumption, the project reduced CO2 emissions from the pilot sites by 186 t a year — reducing CRC costs by nearly £3000 a year.
The subsequent roll-out programme will se M2G units installed on around 30 boilers.
Sabien provided a comprehensive project-management package from the initial feasibility study to final commissioning.
