The main objective for Bouygues Energies & Services at the Evergreen site, is to remotely recover heating and cooling equipment data, in a non-intrusive way, delivered in an easily workable format.
After a visit to the site with the Evergreen manager and a Bouygues Energies & Services supervisor, the Box was installed in December 2018 by the Wattsense team. The Box, located in a technical cabinet on the ground floor, connects to a router from the BMS network. An antenna was installed to improve the weak GSM signal in the building.
The Wattsense team connected to the box on site, scanned the BACnet network and listed all the equipment communicating using this protocol. Fifteen materials were identified, mainly cold or heat production units and electricity meters. This first phase was finished in the morning.
Back at the office, the team configured the Box and launched its BACnet auto-discovery software. Because of the old BACnet version used in the building, some data remained inaccessible; the team quickly developed a specific version of the software to access this data.
Two days later, 4,000 different properties were detected and could be traced back to the Wattsense platform. A file, listing all the available properties was sent to Bouygues Energies & Services which selected about 200, to be delivered every five minutes. The others remain accessible and can be activated on demand.
At the end of December 2018, the embedded software of the Box was updated remotely. During the reset phase, the data was archived and restored as soon as the connection was reestablished.
Wattsense now sends monthly to Bouygues Energies & Services a workable file listing the average hourly data of the 20 most relevant properties.
