Energy Audit with ICONIC Engineering Ltd


In contemporary international, power performance is more important than ever earlier. As the call for strength keeps to upward push and environmental issues develop, groups throughout industries are increasingly turning to energy audits to optimize their strength intake and decrease their carbon footprint. ICONIC Engineering Ltd., a leading player in the discipline of energy audits, has been at the forefront of supporting agencies to identify and put in force energy-saving answers. In this comprehensive manual, we can explore the significance of strength audits, their benefits, and how ICONIC Engineering Ltd. Is revolutionizing the strength audit panorama.

1. Understanding Energy Audits

1.1 What is an Energy Audit?

According to ASHRAE Standard 211, ISO 50002: Energy audits, ISO 50001: Energy management systems, and the European standard EN 16247:

“Energy auditing, according to standard practices, involves a systematic assessment of energy use and efficiency in a building, facility, or industrial process. The reason for an electricity audit is to discover possibilities for power financial savings, improve strength performance, and reduce power fees.”

A strength audit is a scientific examination of an organization's strength consumption, aiming to identify regions of inefficiency and possibilities for development. It includes an in-depth analysis of energy utilization patterns, system overall performance, and constructing structures to expand a complete expertise of the manner energy is implemented within an organization.

1.2 Types of Energy Audits:

The ASHRAE Standard 211 defines three levels of energy audits, each with increasing levels of detail and complexity:

A. ASHRAE Level 1

The Level 1 audit is a simple audit that involves a basic walk-through assessment, a review of utility bills and other applicable operating data, and interviews with operations staff. This basic evaluation is designed to identify glaring energy problems.

Applicable Areas:

  1. Only for office records and staff acknowledgment.

B. ASHRAE Level 2

The Level-2 audit starts with the findings from the Level-1 audit and examines the building energy systems in detail in order to define a number of potential energy-efficiency improvements. This will include the Building Envelope, Lighting, HVAC, Domestic Hot Water, Plug Loads, Compressed Air and Process Uses, and every electrical area.

Applicable Areas:

  1. Fulfills every buyer's requirements.
  2. Fulfills energy audit report requirements for any Bangladeshi Electrical Generation, Transmission, and Distribution Organizations.
  3. Compatibility for audit reports.
  4. Bangladesh Bank’s Sustainability Issues Requirement.
  5. Fulfills any International/Non-International bank loan requirements.

C. ASHRAE Level 3

The ASHRAE Level-3 audit involves a much more detailed information collection over a period of weeks or even months. Data loggers typically are placed temporarily to keep track of the operation of pumps and motors, temperatures of affected spaces, lighting levels, switching behavior, and additional factors.

It mainly details the “Return Period Calculation” of actual investments.

Applicable Areas:

  1. Main requirements for LEED Certification.
  2. Fulfills every buyer's requirements.
  3. Fulfills energy audit report requirements for any Bangladeshi Electrical Generation, Transmission, and Distribution Organizations.
  4. Compatibility for audit reports.
  5. Bangladesh Bank’s Sustainability Issues Requirement.
  6. Fulfills any International/Non-International bank loan requirements.

If we simplify then we can say, there are three primary types of energy audits:

  1. Walk-Through Audit:
    That is an initial evaluation that provides an enormous overview of power intake and identifies capacity areas for development without precise information analysis.

  2. Detailed Audit:
    A greater entire audit regarding information series, tool evaluation, and normal performance assessment. It gives particular hints for strength-inexperienced upgrades.

  3. Advanced Audit:
    That is a pretty exact audit that uses advanced tools and strategies to provide a deep evaluation of power intake, such as simulations and modeling.
