Sabien helps MoD reduce energy costs on 28 sites
Sabien’s M2G boiler load optimisation controls have been installed at 28 Ministry of Defence site across south-east England as a cost-effective way of introducing more savings on boiler energy consumption over and above those achieved by upgrading the building-management system.
The M2G units were selected by PriDE, the joint venture between Interserve Defence and SSE Contracting that manages the Defence Infrastructure Organisation’s south east regional prime contract.
The installation of over 840 M2G units was one of a number of measures carried out by PriDE under a Defence Infrastructure initiative to invest £105 million to improve the efficiency of the Defence estate under the 3-year ‘energy-spend-to-save’ programme. Other measures included upgrading or replacing building-management systems and upgrading lighting.
Eunice Mabey of PriDE explains, ‘To qualify for funding under the spend-to-save programme, we proposed a portfolio of energy-saving measures, which needed to deliver an overall payback within 1.8 years to help achieve the £70 million a year savings target.’
Following installation of the M2G units, a 2-month measurement and verification exercise was carried out on selected sites using methodology in line with the International Performance Measurement & Verification Protocol (IPMVP).
Eunice Mabey explains, ‘The measurement and verification of savings was very important as we needed to demonstrate that the projected savings had been achieved. We worked closely with Sabien in analysing the data that had been collected from the sites.’
