Trend drives energy savings at Jaguar Land Rover

The 26 BEMS-enabled building on Jaguar Land Rover’s Gaydon Centre site have seen significant reductions in energy consumption with the help of Trend Control Systems.

Jaguar Land Rover’s 365 ha Gaydon Centre site in Warwickshire has achieved a 21% reduction in operational CO2 emissions since 2007, despite significant work to extend its facilities. Contributing to these savings has been a Trend BEMS, which achieved energy savings of 4.3 GWH in the five years up to 2012 and 1674 t of CO2.

Andrew Bilbrough, service manager with Trend, explains, ‘Our challenge is to make sure that the BEMS is working effectively and controlling the HVAC facility at Gaydon as efficiently as possible. We operate a comprehensive service-level agreement (SLA) to make sure that the BEMS is correctly maintained, while providing people on site with comfortable working environments.’

The SLA includes condition-based maintenance and implementing quick-win control-strategy modifications for the BEMS using existing hardware.

Neil Hyatt, Trend’s energy manager on site, identifies and recommends additional projects that fall outside the scope of routine maintenance tasks. There are 26 BEMS-enabled buildings.

Measures have included the introduction of variable-speed controls and Trend IQ controllers, matching lighting time zones to occupancy patterns, using time clocks and redesigning control strategies. Savings of 3.5 GWh and 1291 t of CO2 have been achieved.

Each building is managed separately and has its own targets for energy reduction. Operational and energy-meter data for all buildings is monitored centrally via a Trend 963 Supervisor graphical real-time user interface. The 963 Supervisor can learn the structure of the system and make adjustments to how the building services are configured.

Complementing the 963 Supervisor is a Trend Energy Manager software tool that is use for highlighting and investigating energy use. It enables gas and electricity consumption to be monitored and their overall effect on Jaguar Land Rover’s carbon footprint. It also provides information for reports on how to optimise energy consumption throughout the site.

The BEMS is constantly evolving to ensure that the buildings continue to be fully optimised so as to account for changes since initial commissioning.

Trend and Jaguar Land Rover conduct an annual review of the SLA to ensure it meets the requirements of the changing demands of a site that has seen the construction of new buildings and refurbishment of existing facilities.
