Optergy

Optergy builds open, browser-based building automation and energy management products — BACnet controllers, supervisory servers, and tenant-facing energy dashboards. Everything runs in a web browser with no proprietary client software and no per-seat licensing, which keeps long-term ownership cost predictable.

The platform is well suited to mid-size commercial buildings that need real supervisory capability — scheduling, trending, alarms, tenant billing reports, and an occupant-facing energy display — without the cost and complexity of an enterprise controls deployment. Its tenant billing module generates invoices directly from submeter interval data.

Emergent Metering deploys Optergy where a single building or small portfolio needs HVAC supervision, lighting control, and submetering managed together under one open BACnet system rather than stitched across separate vendor platforms.
