Tridium brings integrated control to Oundle School
Simple and effective control of all building control functions is this new facility at Oundle School is provided by a Tridium Niagara Framework.
When Oundle School, a boarding school with 1050 pupils, built a new facility for its biology and chemistry departments, it wanted a single, automated building-management system that could be serviced and maintained by the school’s own team of technicians. That requirement has been achieved with the installation of Tridium’s Niagara Framework by Andromeda Telematics to integrate all building-control functions onto one common platform. To provide energy-efficient environmental control, Andromeda integrated Tridium with a variety of KNX devices that enable all the control elements to communicate with an open standard protocol. The control system integrates heating, ventilation and air-conditioning systems, permanent lighting and emergency-lighting systems, passive window ventilators, solar panels and photo-voltaic equipment. Tridium also provided the HVAC controls for the main plant room to provide boiler sequencing, optimisation, weather compensation and pumps, along with domestic hot water. Ventilation is controlled with Belimo dampers. The underfloor heating and zoned trench heating is controlled via Cheops drives and local room-temperature controllers. The whole site is connected together using a common IP network with Tridium’s Niagara Framework providing the head-end visualisation solution. This offers full colour graphics of all the control applications, viewed with a web browser. Setpoints and items of plant can be monitored and controlled by the graphics, and there is the facility to graph and trend all the systems. Water, gas and electricity are metered, and the energy generated by the photo-voltaic panels is monitored. Chris Irwin, regional director of Tridium Europe, says, ‘This solution allowed for a simple installation, with fewer cables to run and only one system to set up and commission.’ Sensors such as presence detectors maximise energy efficiency and reduce CO2 emissions. Heating and lighting are on only when needed, and lighting is controlled according to available daylight. Electric window motors are connected to CO2 sensors and room temperature controllers to provide natural ventilation.
