Energy Audits (Level 1, 2, 3)

An energy audit is a thorough and detailed inspection, energy survey and analysis of energy flows and consumption patterns in a building particularly usage practices and current energy efficiency levels, carried out by a certified energy manager. Performing an energy audit enables property owners to save money, improve health and safety, and increase the comfort levels of tenants, be it a residential, a commercial or an industrial facility.

EMergy certified energy managers are trained to conduct comprehensive energy audits and identify any loopholes in a building’s efficiency in accordance with local and international standards, including the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). EMergy offers all levels of energy audit that cater to any stage of project development.

ASHRAE Energy Audit Level 1

This energy audit is the most basic and the starting point for building energy efficiency, it requires interaction with facility operating personnel or selected staff to conduct a short interview, a review of utility bills along with other operating data and an onsite visit. More often than not, Preliminary Energy Use Analysis and the Walk-Through Analysis are completed side by side. The goal is to determine the major areas of energy inefficiency and describe corrective measures needed. The data are then collated and used for the preliminary report detailing cost measures and implementation for further study in forthcoming audits. This level of detail, although insufficient for final decision making on implementing proposed measures, suffices for prioritizing energy efficiency projects and to assess if a more detailed audit is required.

ASHRAE Energy Audit Level 2

This level includes preliminary analysis from ASHRAE Level 1, with a more detailed energy calculations and financial analysis of the proposed energy efficiency corrective measures. The financial analysis provides the property owner an elaborate understanding to determine energy efficiency remedial steps that offer the highest efficiency probability. The analysis is directly based on the implementation expected cost, facility operating cost reduction and the property owner’s investment range to determine financial and non-financial objective of audit. This level of audit provides sufficient details to justify project implementation.

ASHRAE Energy Audit Level 3

Level 3 involves a more intricate field data gathering and more meticulous analysis that focuses on potentially capital-intensive projects that were initially identified during the Level 2 Analysis. Building model calibration with the use of the amassed data to provide doable realistic baseline to create a comparative understanding of energy operating services before and after energy project implementation. This level of audit is best appropriate for complex industrial and commercial buildings.

Energy Audits (I,II & III)

An energy audit is essential for a methodical approach to energy management decision-making. An energy audit’s main goal is to identify all of a facility’s energy sources so that total energy input and energy usage may be balanced.
In short Energy Audit can be defined as the verification, monitoring, and analysis of energy usage, including the production of a technical report along with suggestions for increasing energy efficiency with a cost-benefit analysis and an action plan to minimize energy consumption.
Without an energy audit, you might be wasting money on initiatives that you believe would improve your building’s energy efficiency but won’t make a significant difference.

Who need an Energy Audit ?

Energy (both electrical and thermal), labor, and materials are frequently determined to be the top three operational expenditures in every company. If the manageability of the cost or potential cost savings in each of the aforementioned components were compared, energy would consistently come out on top, and therefore the energy management function is a priority area for cost reduction. An energy audit will assist in better understanding how energy and fuel are utilized in any industry, as well as identifying areas where waste might occur and where improvements can be made.
Auditing the energy performance of existing buildings and providing a feasibility assessment for the potential and strategy of Green Certification. The audits result in suggestions for improvements in assets and processes that can enhance the property’s energy efficiency and provide inhabitants with fresh air indoors.

Main Objectives of an Energy Audit

This Energy Audit follows ASHRAE Protocol

ASHRAE Level 1 – Walk-Through Analysis/Preliminary Audit

The most basic audit is the Level 1 audit, often known as a simple audit, screening audit, or walk-through audit. It entails a few brief interviews with site operating employees, a quick examination of facility power bills and other operational data, and a facility walk-through, all aimed at identifying obvious areas of energy waste or inefficiency. The information gathered is then utilized to create a preliminary energy consumption analysis and a report outlining low-cost/no-cost options as well as prospective capital upgrades that may be studied further.

In most cases, a Level 1 audit will only reveal significant issues. Corrective actions are quickly outlined, with fast cost estimates, possible operational cost reductions, and short payback dates offered. While this level of information is insufficient for making a final judgment on whether or not to adopt recommended changes, it is sufficient for prioritizing energy efficiency projects and determining the necessity for a more thorough audit.

When should you have a Level 1 audit?

Before you start making changes to your building’s energy efficiency, it’s crucial to establish a baseline so you can track your progress.

A Level 1 audit can provide stakeholders with an overview of the present state of the building, how it compares to other comparable structures, and which areas require additional study or improvement. A Level 1 audit is an excellent starting point for organizations seeking to get started with improving energy efficiency, or for firms who are having trouble “selling” the need for energy improvements.

ASHRAE Level 2 – Energy Survey and Analysis

ASHRAE Level 1 analysis is included in a Level 2 audit, as well as more comprehensive energy calculations and financial analyses of recommended energy efficiency solutions. The financial study, also known as a Life Cycle Cost Analysis, gives a thorough knowledge of the financial benefits of implementing certain energy efficiency measures to the facility owner.

Utility invoices are gathered for a period of 24 to 36 months so that the auditor may assess the facility’s energy/demand rate structures and energy use patterns. This audit finds all energy-saving strategies that are appropriate for the facility’s operational conditions. Each measure is subjected to a thorough financial analysis based on implementation costs, site-specific operational cost reductions, and the customer’s investment requirements. There is enough information supplied to warrant the project’s implementation.
When should you have a Level 2 audit?

An ASHRAE Level 2 audit is for organizations that want to increase energy efficiency, zero in on how the entire facility is operating, and identify the projects that will deliver the most energy savings for the best return on investment (ROI).

ASHRAE Level 3 – Detailed Analysis of Capital Intensive Modifications

This level of engineering analysis focuses on the prospective capital-intensive projects identified in Level 2 and includes more comprehensive field data collection as well as a more rigorous engineering analysis. It calculates precise project costs and savings with the high level of certainty necessary for large capital investment choices. A thorough audit, detailed audit, or technical analysis audit are all terms used to describe this type of audit. It builds on the Level 2 audit by giving a dynamic model of the existing facility’s energy consumption characteristics as well as all energy saving measures found.

The building model is calibrated using actual utility data to give a realistic baseline against which recommended improvements may be calculated in terms of operational savings. Understanding not only the operational characteristics of all energy-consuming systems, but also the conditions that produce load profile fluctuations on a yearly and daily basis, receives a lot of attention. Sub-metering of key energy-consuming systems and monitoring of system operational parameters are added to existing utility data.

When should you have a Level 3 audit?

Level 3 audits are for companies who have completed a Level 2 audit, identified capital cost initiatives they wish to pursue, but need additional information before making such a large expenditure.

The table below summarizes each level.
Level 1
Level 2
Level 3
A quick on-the-spot inspection of the structure Low-cost/no-cost Energy Conservation Measures: Savings and Cost Analysis (ECMs) Identification of possible capital upgrades that should be given more thought
A more thorough inspection of the structure Breakdown of energy use All ECMs’ savings and costs are analyzed. ECM identification necessitates more extensive data gathering and analysis (Level 3)
During the Level 2 audit, capital-intensive projects were discovered. More in-depth field research Engineering study that is more thorough Calculations of costs and savings with a high level of precision
