The main goal is to find opportunities to reduce energy use, lower costs, and improve overall efficiency without affecting production quality or output.
For factories in Bangladesh, which often face rising energy bills and frequent power supply challenges, an energy audit provides critical insights to optimize energy use and maintain competitiveness in the market.
Types of Energy Audits
Energy audits can vary in complexity depending on the level of detail and investment required. The three main types are:
Preliminary (or Walk-Through) Audit:
This is a quick review of the factory’s energy systems. Auditors walk through the site, inspect major equipment, and identify obvious energy wastage areas. It provides a high-level overview and suggests quick, low-cost fixes.
Detailed Energy Audit:
This audit involves in-depth data collection and analysis. Auditors measure energy flows, review operational patterns, and calculate potential savings. It provides a detailed report with recommended energy-saving measures, including estimated costs and payback periods.
Investment-Grade Audit:
This is the most comprehensive audit, intended to support financial decisions for major energy efficiency projects. It includes rigorous data collection, detailed cost-benefit analysis, and project implementation planning. This type of audit helps secure funding or loans by providing confidence in projected savings.
