BMS + Enerzyz
What your BMS does
What Enerzyz adds
Monitoring
Live plant status, trends and alarms across connected equipment.
Reads that same data continuously and analyses it for energy waste.
Control
The authoritative control layer. Every command executes through it.
No separate control path. Supervisory set-points are written back through your BMS.
Rules and schedules
Executes the schedules and set-points your engineers configure.
Recalculates the best set-points as conditions change, within limits you approve.
Data analysis
Trend logs and reporting for your engineers to interpret.
Physics-informed digital twins and machine-learning models interpreting continuously.
Changing conditions
Responds according to how it has been configured.
Adapts as weather, occupancy and load move through the day.
Continuous optimisation
Periodic tuning by your team or your contractor.
Runs continuously without adding to your engineering workload.
Cross-system optimisation
Strong within the systems it controls.
Coordinates chillers, AHUs, pumps and metering together.
Digital twin
Not typically part of a BMS.
A live model of your plant, used to find the optimal settings before they are applied.
Learning over time
Configuration holds until someone changes it.
Performance improves as the model learns your building.
Engineering control
Your team owns it.
Read-only by default. Every action is logged and reversible, and your operators retain override authority at all times.

Enerzyz analysis & optimisation
Your BMS

Telemetry flows up. Supervisory set-points are written back through your BMS, which remains the authoritative control layer. Every action is logged with its justification, and human operators retain override authority at all times.
What implementation actually looks like
Physical installation typically takes minutes to half a day, depending on the facility and the connection path. Enerzyz then runs in read-only mode while it establishes your baseline, typically two to four weeks, and active optimisation begins once sufficient baseline data has been established.
Enerzyz can also identify abnormal operating patterns that may indicate developing issues before they become failures.
Real-world proof
Verified results · InterContinental Dhaka, Bangladesh
They already had a Johnson Controls BMS.
−25.8%
HVAC energy reduction
−US$26,301
Quarterly cost saving
−219,441 kWh
Quarterly energy reduction
−61.45 tCO₂e
Quarterly carbon reduction
InterContinental Dhaka did not replace its building management system. Enerzyz integrated with the existing Johnson Controls BMS and delivered verified savings across HVAC, chilled water and peripheral systems within three months, with zero operational disruption. Results are measured against an independently audited IPMVP baseline.
These are InterContinental Dhaka’s results. They are specific to that property and are not typical or guaranteed.
