The Priva BMS, comprising six Compri HX4, two Compri HX3 and two Compri HX8E controllers, has been installed within two new office buildings. During office hours all change-of-state and critical alarms report to a nominated PC within the facilities management department. It is only when the premises are vacated that the alarm reporting procedure is switched to the security staffs’ mobile phones.

The success of this remote messaging has led Chevron to consider extending the remote connection to include use by suppliers. For example, during the BMS installation period Campbell Control Services utilized the modem connection to remotely check the BMS installation, initialize diagnostics and make program adjustments as required. This enabled the company to quickly respond to any adjustments from their office in Glasgow, achieving valuable savings, in time and engineering costs, as their engineers need not travel to site to complete the work.

The new buildings are providing fully air conditioned office accommodation plus two IT suites. Heating and cooling is via a fan coil unit (FCU) system, with 240 Comforte CX controllers managing the FCUs. These in turn are connected to a mix of Comset CX room units and standard room sensors for local control. The IT suites come complete with their own dedicated, self controlled, air conditioning systems that have been interfaced with the Priva BMS for monitoring purposes using a Modbus connection; all other HVAC services are directly monitored and controlled by the BMS.

The Priva system is now fully operational, having been delivered to specification, on time and on budget by Campbell Control Services.
