Building Management.
The building, on a single dashboard.

A BMS is the supervisory control layer that orchestrates HVAC, lighting and life-safety into one operating picture, typically paying back in 18–36 months. The supervisory control layer that orchestrates HVAC, lighting and life-safety into one operating picture. It sets chiller schedules, adjusts AHU dampers based on CO₂ levels, dims lighting on daylight harvesting, and surfaces deviations from normal as alarms. The right BMS pays back in 18–36 months purely through HVAC and lighting energy savings.

Choose Siemens Desigo for large HVAC-heavy campuses, Honeywell for tenant-billing dashboards, and Johnson Controls Metasys for very large enterprise estates. By analytics maturity and integration breadth. Siemens Desigo is excellent on large campuses with deep HVAC integration. Honeywell is strong on tenant-billing dashboards. Johnson Controls Metasys suits very large enterprise estates. We are vendor-flexible — we recommend by project profile, not partnership.

Lithium-ion BESS is now the default for new mission-critical UPS above 20 kVA because eight-year lifetime cost is 30–45% lower than VRLA despite a 1.8× initial premium. The eight-year economics flipped. Lithium-ion delivers 3–4× cycle life, half the floor space, and a fraction of the maintenance versus VRLA. Initial cost is ~1.8× but lifetime cost is typically 30–45% lower. Above 20 kVA in any new installation, lithium is now the right answer in almost every case.

Yes — BMS retrofits run zone-by-zone with new and legacy systems in parallel during cutover, typically 8–14 weeks for a commercial tower without operational shutdown. We stage retrofits in zones, run new and legacy systems in parallel during the cutover window, and schedule controller swaps for off-hours. A typical commercial-tower retrofit takes 8–14 weeks with no operational shutdown of the tenants.

Yes — the BMS dashboard is designed for the facilities team to operate without us, with named alarms in plain English and escalation routing to mobile devices. That is the test we design to. The supervisory layer is configured around the priorities the facilities lead actually monitors, with named alarms in plain English rather than vendor codes, escalation routing to mobile devices, and a daily operations report that lands in the facility manager's inbox. The dashboard is theirs after handover, not ours.

A BESS rides through transient events instantly, peak-shaves against demand-charge tariffs and absorbs solar over-generation — complementary to a generator, not a replacement. Riding through transient events instantly, peak-shaving against demand-charge tariffs, and absorbing solar over-generation where rooftop PV is in scope. A diesel generator still has its place for sustained outage backup, but the first 30–60 seconds of any grid event — which is where most equipment damage and process disruption occurs — is BESS territory now. The two layers are complementary, not competitive.
