One secure platform for all your buildings
Keep your existing BMS and manage multiple sites from one central dashboard with live status, alarms, trends and scheduled reports.
MANAGED CLOUD BMS SERVICES
Citrine Engineering provides managed Cloud BMS services, including platform setup, monitoring, backups, data tools, system maintenance and technical support.
KEEP YOUR EXISTING BMS
Connect every site without replacing working controllers
Citrine adds a Niagara JACE and secure firewall at each site, then connects them to a central Niagara Supervisor in your Microsoft Azure environment through an encrypted outbound connection.
- One portfolio viewSee buildings, live values, alarms, trends and reports from one screen.
- Local control remainsDDC, PLC and JACE control continues on site if the internet or cloud is unavailable.
- Scales with your sitesStart with one building and expand to as many as 30 sites on the same platform.
- Managed and supportedMonitoring, patching, backups and technical support are managed by Citrine.

03 / Niagara 4 BMS GUI Upgrade
Your Niagara BMS, upgraded
Modern web screens for alarms, trends, energy reports and 3D equipment graphics, running on the Niagara 4 station you already have. Same station, same points, same users and permissions. Nothing to migrate: we upgrade the screens.
A / CUSTOMISED 3D EQUIPMENT GRAPHICS
3D graphics customised to your real site
Each 3D graphic is built from the equipment actually installed on your site and linked to your existing Niagara points. Live readings sit beside every part, running equipment animates, and a trip is impossible to miss.

B / NIAGARA 4 FEATURE UPGRADES
Every standard Niagara 4 feature, made easier to use
Each app replaces a standard Niagara 4 screen with a faster browser version and adds the tools operators ask for. All apps sit in one portal on the station, so switching between them is instant. Light for offices and bright rooms, dark for control rooms and video walls: one switch in the portal, and every app follows it.
