Enerzyz and your BMS

Already have a BMS? Good.

Enerzyz works with it, not instead of it.

Your BMS is the control layer, and it stays that way. Enerzyz adds a layer of continuous analysis on top: it reads the data your BMS already produces, works out the best operating settings as conditions change, and sends them back through your BMS to act on. Nothing is replaced and nothing is ripped out.

BMS + Enerzyz

Monitoring

What your BMS does

Live plant status, trends and alarms across connected equipment.

What Enerzyz adds

Reads that same data continuously and analyses it for energy waste.

Control

What your BMS does

The authoritative control layer. Every command executes through it.

What Enerzyz adds

No separate control path. Supervisory set-points are written back through your BMS.

Rules and schedules

What your BMS does

Executes the schedules and set-points your engineers configure.

What Enerzyz adds

Recalculates the best set-points as conditions change, within limits you approve.

Data analysis

What your BMS does

Trend logs and reporting for your engineers to interpret.

What Enerzyz adds

Physics-informed digital twins and machine-learning models interpreting continuously.

Changing conditions

What your BMS does

Responds according to how it has been configured.

What Enerzyz adds

Adapts as weather, occupancy and load move through the day.

Continuous optimisation

What your BMS does

Periodic tuning by your team or your contractor.

What Enerzyz adds

Runs continuously without adding to your engineering workload.

Cross-system optimisation

What your BMS does

Strong within the systems it controls.

What Enerzyz adds

Coordinates chillers, AHUs, pumps and metering together.

Digital twin

What your BMS does

Not typically part of a BMS.

What Enerzyz adds

A live model of your plant, used to find the optimal settings before they are applied.

Learning over time

What your BMS does

Configuration holds until someone changes it.

What Enerzyz adds

Performance improves as the model learns your building.

Engineering control

What your BMS does

Your team owns it.

What Enerzyz adds

Read-only by default. Every action is logged and reversible, and your operators retain override authority at all times.

How they work together

Building equipment

Your BMS

Enerzyz analysis & optimisation

Your BMS

Building equipment

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.

When Enerzyz adds value

Operating conditions change through the day, but set-points were configured for a design case.
Schedules and set-points were correct when commissioned and have not been revisited since.
Several systems — chillers, AHUs, pumps — need optimising together rather than one at a time.
Energy consumption is hard to attribute to specific plant or areas.
Your engineering team does not have time for continuous manual tuning.
Management wants savings measured against an independently audited baseline, not estimated.
