Energy Audit

1. Introduction

An Energy Audit is the verification, monitoring, and analysis of energy use, along with the preparation of a technical report containing:

• Recommendations for improving energy efficiency
• Cost-benefit analysis
• Action plan to reduce overall energy consumption

Phases of Energy Audit

1. Preliminary Energy Audit (Walk-through Audit):
   • A relatively quick exercise
   • Uses easily available data
   • Helps in identifying obvious areas for savings
2. Detailed Energy Audit:
   • Involves thorough investigation and analysis
   • Establishes energy balances for specific process equipment
   • Identifies major energy losses and opportunities for savings

2. Scope of Energy Audit

a) Electrical Systems / Power Quality

The audit involves a detailed study of electrical systems, including load distribution and electrical parameters at substations and transformers.

Key aspects:

• Electrical Bill Analysis (cost and consumption patterns)
• Demand Analysis (maximum demand, demand charges)
• Time of Day (TOD) Tariff Benefits
• Minimization of Distribution Losses
• Power Factor Improvement (reduction of reactive power penalty)
• Load Factor Improvement Study
• Harmonic Analysis (distortion in electrical signals)
• Electrical Metering Study (accuracy and adequacy of metering)

b) Lighting Systems

A lighting audit can lead to considerable energy savings.

Process:

• Measurement of luminance levels using a Lux Meter
• Comparison with recommended standards for workplace lighting
• Identification of areas for improvement in:
  • Type of lamps/fixtures
  • Use of natural daylight
  • Automatic controls (sensors, timers, dimmers)
  • Replacement of inefficient lamps with energy-efficient alternatives (LEDs, CFLs, etc.)

Manufacturing of Proximity and power saving sensors

Proximity Sensors and Power-Saving Sensors

• Devices that detect the presence or absence of a person/object within a defined range without any physical contact.
• Applications in Energy Saving:
  • Automatically turn lights or appliances ON when a person enters the area.
  • Turn OFF when no presence is detected, thereby avoiding unnecessary consumption.
• Common Use Cases:
  • Office cabins, classrooms, corridors, washrooms
  • Automatic door operations
  • Smart street lighting
• Benefits:
  • Reduce electricity wastage
  • Enhance equipment lifespan (less operating hours)
  • Improve overall energy efficiency
  • Immediate payback in high-usage areas
