Environmental Management System delivers 19.3% reduction in electricity consumption over three years
The client was tasked with introducing an environmental management system (EMS) to the site and achieving ISO14001 certification back in 2011. EVORA were engaged with due to the knowledge and experience of the team in implementing and maintaining EMSs. Since the original engagement, the relationship has grown and developed to ensure that energy and environmental performance is maximised.
At Belgrave House a ISO14001 certified EMS has been in place for several years. Each year objectives are set focussed on the main environmental impacts of the site, which are primarily energy related.
The General Manager of the building was a key driver for the EMS and the associated improvements, ensuring that appropriate resource was available in order to achieve the aims of the EMS. Improvements included:
• Installation of LED lighting and improved controls
• Installation of three phases of solar photo-voltaic (PV) panels to the roof
• Significant revisions to building management system (BMS) timings
• Comprehensive staff and contractor training programmes and engagement with tenants
Performance in 2017 was outstanding, electricity consumption fell in comparison to 2016 by 1,278,000kWh, a saving of 19.3%. This is a cost saving of approximately £127,800. This was achieved over a period where occupancy at Belgrave House had remained at 100% across both years. Gas consumption also fell by almost 175,000kWh (-12.7%) in 2017 in comparison to 2016. Although weather conditions were milder (so heating demand was expected to fall), when normalised for milder conditions a reduction of 8.8% was still achieved.
Over a longer period, electricity consumption has fallen by 1.7 million kWh in comparison to 2014 and by almost 2 million kWh in comparison to 2011. Annual electricity costs have therefore fallen by almost £200,000 in comparison to 2011.
In conjunction with the fall in electricity consumption, carbon emissions from the building have also fallen significantly which has reduced the cost liability of the building under the Carbon Reduction Commitment in addition to the emitting a reduced level of greenhouse gas to the atmosphere.
EVORA has worked with the building management team to ensure the EMS benefits are wide ranging, including the:
• Tenants – who benefit from reduced energy consumption and a knowledge that the building is being run efficiently and in line with environmental legislative requirements
• Owner who benefits from the knowledge that the building is being effectively managed, is compliant with legislation and is future proofed against potential rising utility costs.
• Employees and contractors benefit from enhanced training and awareness of environmental related topics. They are actively encouraged to contribute to the sustainability of the building.
