Your BMS monitors. It doesn't continuously optimise. Operating conditions change every day.
Enerzyz connects to what you already have, and keeps optimising it.
01
Connect
Connects securely to your existing BMS, chillers and HVAC. No rip-and-replace.
02
Analyse
A live digital twin learns how your building actually consumes energy and finds the optimal settings.
03
Optimise
It holds those settings in real time, adapting as conditions change, always within limits your engineers approve.
Installation is non-disruptive and typically takes under a day. Enerzyz then runs read-only while it establishes your baseline, with active optimisation typically beginning 2–4 weeks after installation.
Whole-building energy typically falls 15–25%; individual assets such as HVAC can see up to 40%.
