Tech OVN

Energy Management System for Hospitals & Multi-Specialty Healthcare

An Energy Management System (EMS) for hospitals — OT and ICU critical-load monitoring, DG / grid / UPS redundancy validation, departmental cost allocation, and NABH-aligned reporting. Class 0.5S Titan meters and IEC 61000-4-30 Class A power-quality monitoring on every critical feeder.

Tech OVN Energy Management System for hospitals — OT/ICU critical-load monitoring and departmental cost allocation

In a Hospital, Energy Data Is Patient-Safety Data

A transfer-switch glitch in an OT, a UPS battery string that degrades silently, a chiller drift in NICU — these aren't just energy events. They're patient-safety events. A hospital's Energy Management System has to do two jobs at once: identify the 20–30% energy waste buried in HVAC, sterilisation and lighting; and continuously validate that the critical loads keeping patients alive are on the redundancy path they were designed for.

The Tech OVN EMS combines Class 0.5S submetering, IEC 61000-4-30 Class A power-quality monitoring on OT / ICU feeders, and independent metering of grid, DG, and UPS sources. Deployed across multi-specialty hospitals, NABH-accredited facilities, and IGBC Green Hospital projects in India and the Middle East — by facilities directors, clinical engineering teams, and corporate sustainability heads.

What a Hospital EMS Does

Six capabilities that combine clinical-grade reliability with waste-reduction analytics — on the same platform.

OT / ICU Critical-Load Monitoring

Continuous monitoring of operation theatre and ICU power feeds — voltage stability, frequency, sags, swells, and transient events. Catch a deteriorating UPS or a degrading DG switchover before it interrupts a procedure.

DG / Grid / UPS Redundancy Validation

Track grid, diesel generator, and UPS feeds independently. Detect transfer-switch operations, verify that critical loads are actually on the right source, and log every outage and switchover for NABH evidence.

Departmental Cost Allocation

Submetering by department, floor, and wing — OT, ICU, radiology, laboratory, OPD, cafeteria, administration. Each department sees its own energy KPI; finance gets defensible numbers for cost recovery.

HVAC, Chiller & Sterilisation Load Tracking

HVAC and sterilisation are typically the top two energy consumers in a hospital. Per-chiller, per-AHU, and per-autoclave submetering surfaces waste — including the 24×7 zones that don't need 24×7 cooling.

Power Quality Logging (Titan PQ)

IEC 61000-4-30 Class A power-quality monitoring on critical feeders. Sag / swell logs, harmonic distortion analysis, and event reports — useful for equipment-failure investigation and warranty disputes.

NABH & Green Hospital Reporting

Audit-ready energy reports for NABH accreditation evidence, IGBC Green Hospital ratings, and ESG / sustainability submissions. Auto-generated PDF / Excel reports per department, per shift, per quarter.

Frequently Asked Questions

NABH, OT / ICU power quality, departmental cost allocation, redundancy validation — common questions from hospital facilities and clinical engineering teams.

NABH's facility management standards require evidence of utility monitoring, redundancy validation, and incident logging for power-related events. The Tech OVN EMS provides continuous metering on critical feeders (OT, ICU, NICU, dialysis), automatic logging of every outage, every transfer-switch operation, and every PQ event, and exports audit-ready reports that hospital quality teams hand directly to NABH assessors.
Yes. The Titan PQ variant provides IEC 61000-4-30 Class A power quality monitoring — sags, swells, transients, harmonics, flicker — on critical OT and ICU feeders. This is invaluable when a high-value imaging machine (CT, MRI, cath lab) trips intermittently and the manufacturer asks for power-quality logs before honouring warranty.
Yes. The platform supports submetering by department, floor, and wing, with role-based dashboards so each department head sees only their own load profile and cost. Finance and corporate medical insurance teams use this for internal cost recovery and for benchmarking energy intensity per occupied bed across multi-hospital chains.
By metering grid, DG, and UPS feeds independently, the EMS continuously verifies that critical loads (OT, ICU, dialysis, NICU) are on the correct redundant source. Every transfer-switch operation is logged with timestamp and duration. The platform alerts immediately if a critical load is left on the wrong source after a switchover.
Yes. The platform was designed for portfolios. Hospital chains use it to benchmark energy intensity (kWh per occupied bed-day) across facilities, identify the most efficient site, and replicate its operating pattern. Role-based access lets corporate sustainability teams see consolidated data while site facility managers see only their own hospital.
