Trend BEMS driving energy savings at Jaguar Land Rover

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 on site Energy Manager, identifies, highlights and recommends any additional projects that fall outside the scope of routine maintenance tasks. There are 26 BEMS-enabled buildings.

Some of the adopted measures included the introduction of variable-speed controls and Trend IQ controllers, which match lighting time zones to occupancy patterns, using time clocks and redesigning control strategies. This resulted in savings of 3.5 GWh and 1291 t of CO2.

Each building on site is independently managed, and has it’s own individual 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 used for highlighting and analysing energy use. It enables gas and electricity consumption to be routinely monitored and assesses their overall effect on Jaguar Land Rover’s carbon footprint.

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.
