An energy audit is a systematic evaluation of how energy is consumed in a facility, aimed at identifying inefficiencies, reducing energy costs, and improving overall energy performance.

An energy audit is a systematic evaluation of how energy is consumed in a facility, aimed at identifying inefficiencies, reducing energy costs, and improving overall energy performance.

Yes. For Designated Consumers (DCs) notified by the Bureau of Energy Efficiency (BEE), periodic energy audits are mandatory under the Energy Conservation Act.

  • Walk-through / Preliminary Audit

  • Detailed Energy Audit

  • Investment Grade Audit

  • Equipment-specific Audit (HVAC, pumps, compressors, electrical)

Typical timelines:

  • Small buildings: 3–5 days

  • Industrial plants: 2–4 weeks

  • Large campuses / data centres: 3–6 weeks

Most facilities achieve 5%–25% energy savings, depending on baseline performance and implementation level.

No. Audits are conducted during normal operations with minimal or no disruption.

  • Electricity & fuel bills

  • Equipment details

  • Operating schedules

  • Single-line diagrams

  • Production or occupancy data

ECMs are technical or operational improvements that reduce energy consumption without affecting output or comfort.

Yes. We support technical specifications, vendor evaluation, implementation monitoring, and savings validation.

A power quality audit assesses voltage, current, harmonics, power factor, unbalance, and disturbances affecting electrical reliability.

Poor power quality can cause:

  • Equipment overheating

  • Frequent tripping

  • Higher losses

  • Reduced equipment life

Studies typically follow:

  • IEEE 519

  • IEC standards

  • CEA regulations

Harmonics are electrical distortions caused by non-linear loads like VFDs, UPS, and IT equipment, leading to losses and overheating.

Harmonics are electrical distortions caused by non-linear loads like VFDs, UPS, and IT equipment, leading to losses and overheating.

Yes. Harmonics and poor PF increase losses, demand charges, and maintenance costs.

Typically 7 days to 14 days, depending on system complexity and load variation.

Thermal imaging uses infrared cameras to detect abnormal temperature rise in electrical and mechanical systems.

Yes. It helps identify fire risks, loose connections, overloading, and insulation failures.

Yes. It is a live, non-intrusive diagnostic technique.

  • Critical facilities: Every 6 months

  • Others: Annually

  • Transformers
  • LT & HT panels
  • Bus ducts
  • Motors and MCCs
  • DG sets

Yes. HVAC audits cover chillers, VRF/VRV systems, AHUs, pumps, cooling towers, and controls.

It evaluates chiller efficiency (kW/TR), part-load performance, and improvement opportunities.

Yes. Pump audits assess flow, head, efficiency, throttling losses, and VFD potential.

It evaluates compressor efficiency, leakages, pressure drops, and control strategy.

Yes. DG audits cover loading, fuel efficiency, harmonics, and operational practices.

Power Usage Effectiveness (PUE) measures how efficiently a data centre uses energy.

  • Excellent: ≤ 1.4

  • Average: 1.6–1.8

  • Poor: > 2.0

EPI is annual energy consumption per built-up area, expressed as kWh/m²/year.

Yes. We benchmark against industry best practices and peer facilities.

M&V confirms actual energy savings achieved after implementing ECMs.

We follow International Performance Measurement and Verification Protocol (IPMVP).

It reduces emissions, improves efficiency metrics, and strengthens ESG reporting credibility.

CCTS is India’s mechanism to trade verified carbon emission reductions.

Industries with high energy use, emission targets, or Net-Zero commitments.

Yes. We support data collection, baselining, metrics, and disclosures.

Yes. All client information is handled under strict confidentiality.

Yes. Scope is tailored to client objectives, industry, and compliance needs.

Yes. We execute projects pan-India.

Yes, subject to scope and contractual requirements.

Yes. We assist in prioritization, approvals, implementation, and verification.

Yes. Audits support compliance with energy, electrical, and safety regulations.

Manufacturing, data centres, hotels, hospitals, commercial buildings, cold storage, infrastructure, and warehouses.

Our audits are:

  • Data-driven

  • Implementation-focused

  • Standards-aligned

  • ROI-oriented

Yes. We conduct energy efficiency and awareness training.

Yes. We support design review and energy-efficient planning.

Every 2–3 years, or after major capacity changes.
