ES-IGW-B1
Data Concentrator
The ES-IGW-B1 reads chains of energy meters on RS485 and controllers over Modbus TCP, which covers most building metering.

Commercial Buildings
Energy monitoring for commercial buildings, floor by floor
Offices and malls run HVAC, lifts and generators all day, and the bill rarely shows where the energy went. En-Stream tracks every meter in one live view, so you can see consumption and generator costs per floor or tenant.
The problem
Where building energy goes unseen
One bill, many users
A single bill doesn't show which floor, tenant or system used the energy, so costs are hard to share fairly.
HVAC runs on autopilot
Chillers, air handlers and fans often run longer than the building needs, and nobody notices until the bill arrives.
Generator hours add up
During outages the generator carries the building, and its fuel cost is rarely tracked against the load it served.
What to measure
Readings that matter in a commercial building
En-Stream reads these from your existing meters and building controllers, or from sensors wired to a gateway.
Energy per floor or tenant
kWh from sub-meters on each floor, tenant or shared system.
HVAC
Power and running status of chillers, air handlers and fans.
Generator and fuel
Generator output and fuel use, next to grid and solar.
Lifts, pumps and shared services
Consumption of lifts, water pumps and other shared loads from their meters.
Supply by source
Grid, generator and solar, live, with what the building uses compared against what it generates.
Dashboards
Dashboards building managers use
Custom Dashboards
A view per floor, tenant or system, so facility and finance teams each see what matters to them.
Consumption vs Generation
What the building uses against what its solar produces, to find the gaps that drive up the bill.
Energy Flow
Grid, generator and solar feeding the building live, and which source carries the load.

FAQ
Commercial building monitoring FAQ
Can En-Stream show energy use per floor or tenant?
Yes. With a meter per floor, tenant or system, En-Stream shows each one's consumption, so costs can be shared on measured data.
Can we track the generator as well as the grid?
Yes. The Energy Flow view shows power from solar, grid and generator into the building live, and the Utilities view tracks fuel next to electricity.
Do we need to replace our existing meters?
No. En-Stream gateways connect to the meters, controllers and sensors you already run, including legacy equipment.
Can several buildings be monitored together?
Yes. Every site reports to the same platform, and remote access lets you open the dashboards from any device.
