Tech OVN

Energy Management System for Commercial Buildings, Offices & Malls

An Energy Management System (EMS) for commercial real estate on the Tech OVN Energy Intelligence Platform — per-tenant chargeback billing, HVAC and chiller-plant optimisation, and LEED / IGBC / GRIHA / BRSR-aligned reporting. Deployed across malls, IT parks, office towers, and mixed-use developments.

Tech OVN Energy Management System for commercial buildings — tenant submetering and BMS integration

Flat-Rate Billing Hides Waste. So Does Aggregated Consumption.

In most commercial buildings, tenants are billed on a flat per-sqft basis, common-area HVAC runs on a fixed schedule whether occupied or not, and the only line of sight building owners have into consumption is the monthly utility bill. A real Energy Management System replaces all of that with per-tenant, per-floor, per-asset visibility — turning consumption data into chargeback bills, BMS optimisation inputs, and ESG disclosures.

The Tech OVN EMS combines Titan meters with the Tech OVN Energy Intelligence Platform — a multi-tenant cloud SaaS built for commercial real estate. Deployed across malls, IT parks, office towers, and mixed-use developments — by building owners, property managers, REIT asset managers, and ESG / sustainability teams. Meters report to the platform natively over secure MQTT, no gateway hardware required.

What a Commercial-Building EMS Does

Six capabilities that turn passive building data into tenant bills, BMS optimisation, and ESG disclosures.

Per-Tenant, Per-Floor Submetering

Titan meters at every tenant supply, every floor, every common-area panel. Tenant-level chargeback with audit-ready bills replaces flat-rate billing — and exposes the floors quietly drawing 2× the average.

Tenant Chargeback Bills, Generated for You

Configurable tariff structures (flat, ToD, demand, slabs) and automated monthly invoicing on the Tech OVN Energy Intelligence Platform. Each tenant logs in to see only their own consumption and bills.

HVAC & Chiller Plant Optimisation

Chillers, AHUs, cooling-tower fans, and pumps submetered individually. Identify the chiller running at the wrong sequence, the AHU that's still on after-hours, and the cooling-tower fan losing performance over time.

After-Hours & Phantom Load Detection

Real-time alerts for loads running outside scheduled hours. Phantom power, idle equipment, and after-hours HVAC are typically the biggest 10–30% energy savings opportunity in a commercial building — and the easiest to act on.

ESG / BRSR / LEED / GRIHA Reporting

Auto-calculated Scope 2 carbon emissions, renewable mix percentages, EPI (Energy Performance Index) per sqm. Audit-ready reports for BRSR (Business Responsibility & Sustainability Reporting), LEED EAc credits, IGBC / GRIHA assessments, and CDP submissions.

Multi-Property Portfolio View

Benchmark energy intensity across your buildings — kWh per sqm, kWh per occupied seat, EPI per asset. Identify your most efficient property and replicate its operating pattern across the portfolio.

Frequently Asked Questions

BMS vs EMS, tenant billing, LEED / IGBC / GRIHA, BRSR, and ROI — common questions from building owners, property managers, and ESG teams.

A BMS (Building Management System) controls HVAC, lighting, and access at a building level. An EMS focuses specifically on measurement, analysis, and optimisation of energy consumption. The Tech OVN EMS is a self-contained stack — Titan meters report to the Tech OVN Energy Intelligence Platform natively over secure MQTT — and runs alongside any BMS you already have, rather than replacing it. The platform handles tenant chargeback, ESG reporting, and portfolio benchmarking that no BMS does well on its own.
Yes. Titan meters at every tenant supply feed automated chargeback on the Tech OVN Energy Intelligence Platform. The platform supports multi-tenant access (each tenant sees only their own consumption), automated monthly invoicing, configurable tariff structures (TOU, demand charges, slabs), and audit-ready supporting data for dispute resolution.
Yes. The platform auto-calculates EPI (Energy Performance Index) per sqm, tracks consumption against ECBC and LEED baselines, and exports the evidence needed for LEED EAc credits (Existing Buildings: Operations & Maintenance, BD+C, ID+C), IGBC Green New Buildings ratings, and GRIHA assessments. Used by green building consultants across India.
BRSR Principle 6 (environment) requires disclosure of total energy consumption, energy intensity per rupee of turnover, and renewable energy share. The EMS provides these metrics automatically — per asset, per portfolio, per year — with audit-ready supporting data. Scope 2 emissions are auto-calculated using region-specific grid emission factors and renewable PPA inputs.
Most commercial buildings recover the cost of meters + cloud platform within 12–18 months. Industry studies consistently show 10–30% energy cost reduction in the first year — driven by after-hours load identification, HVAC schedule corrections, chiller-plant optimisation, and tenant behaviour change once they see their own consumption on a dashboard.
