BMS takes control of thermal baths in Bath
The comprehensive building-management system in the new Gainsborough Bath Spa 5-star hotel not only controls services in the 99 bedrooms and public areas, but also the temperature of the thermal baths that can draw from the thermal mineral-rich waters from the city’s Roman Baths.
Originally built in the 1800s, the hotel occupied two Grade II-listed buildings with Georgian and Victorian facades.
The BMS was designed and installed by BG Energy Solutions and is based on a selection of technologies from its principal suppliers.
The system controls the temperatures of the main thermal bath at 35°C and two smaller thermal baths at 40 and 35°C. Also served by the water are sauna, steam room and ice alcove facilities — along with a thermal-water fountain and relaxation terrace.
Simon Shaw, senior project engineer with BG Energy Solutions, explains, ‘We based the BMS on Cylon BACnet building-management controllers in the main panels and best-of-breed BACnet FCU fan coil controllers in each of the hotel’s 99 bedrooms, while common areas such as treatment rooms and restaurants feature banks of FCUs.
‘The supervisor workstation uses a BACnet open protocol head-end by Delta Controls called enteliWeb, thus delivering a seamless BMS interface. In short, any PC connected to the BMS network will have access to the graphics.’
The BMS constantly monitors the bedroom conditions. If the room temperature deviates too far away from desired conditions, even if the room is not occupied, the FCU will be enabled to correct the temperature.
The BMS also monitors lifts and numerous meters — including those for electricity, gas and mains water.
