Monitoring and Targeting

Managing energy and water consumption in over 330 buildings is challenging. To help in managing these utilities; Estates and Buildings have a sophisticated energy management software package (SystemsLink) which enables us to closely monitor our utility consumption in a large number of buildings. This provides timely and accurate consumption and cost reports as well as validating our utility invoices to ensure we are not being overcharged.

During recent years we have installed additional sub metering in buildings across both our Durham and Stockton campuses and have installed a large number of AMR (Automatic Meter Reading) devices which now cover a large proportion of our electrcity and gas consumption. This provides building energy consumption profile data and together with space management information enables building performance to be measured in relation to floor area, the identification of energy saving opportunties and assessment of the impact of energy efficiency initiatives.

We now have a web-based ‘dashboard’ system (SystemsLink), which enables us to share energy consumption data with our Environment Champions and other relevant stakeholders. This data is available one day after it is logged, meaning that timely action can be taken when energy wastage is identified. We are working with SystemsLink to continually improve this system. The User Guide for SystemsLink can be found here.

Building Management System

To optimise energy consumption within our buildings, the University operates a Building Management System (BMS).

A Building Management System (BMS) controls and monitors a building's mechanical and electrical equipment such as heating, air handling and cooling plant systems, lighting, power systems and security systems. A well specified, installed, maintained and operated BMS should deliver overall 15-20% energy savings compared with standard control systems.

The BMS system at Durham uses internal and external sensors to monitor and make adjustments to the Buildings' heating and ventilation systems to enable the most efficient use of energy, whilst providing the internal conditions required by users, within the constraints of the university energy management strategy.

The Building Management System at Durham is managed by Grant Potter (Building Management System Engineer) in Estates and Buildings.
