BMS meets demands of Sikh temple
Clarkson Controls has recently completed the installation of an Elesta composite building-management system for the new 3-storey Sikh temple at Leamington Spa. The nature of the various activities in the temple mean that its occupancy can vary from fewer than 10 people to several thousand, so the demands for heating and ventilation vary enormously.
The main motor-control centre is in the boiler room in the basement and control the boiler and DHW plant, four AHUs on the roof and the main kitchen- and toilet-extract systems.
The boiler plant is demand based and serves underfloor heating systems and heating coils in the AHUs. Room temperature and return-air CO2 duct sensors are used by the BMS to control the AHU coils. An external temperature sensor provides the required influence for the variable-temperature control to the underfloor-heating manifolds. Summer/Winter set points, core-hours time control and frost protection is also provided. C2 extension timers and occupancy level units are provided in each are for unscheduled plant operation. All plant is sequence controlled for maximum energy savings.
The motor-control panel containing the Elesta RCO-D controller and interface modules is connected via IP addressable communications to the Clarkson BACnet web browser in the control panel to provide for remote interrogation and changes to system parameters.
Fire safety is provided by pressurising the four staircases on each corner of the building, with links to the main fire-alarm system.
