This level of engineering analysis focuses on potential capital-intensive projects identified during the Level II analysis and involves more detailed field data gathering as well as a more rigorous engineering analysis.
The Level III audit is typically reserved for complex commercial and industrial buildings with very specific and accurate economic payback analysis requirements. The Level III audit involves collecting long term trend data using data logging devices and information fed from the buildings energy management or building management systems. The high resolution data that is collected enables us to perform calculations that can be used to very accurately predict energy and cost savings.
Greater consistency in approach also holds the promise for lowering costs if energy auditors can establish consistent reporting, rather than custom approaches that are often required by different contracting entities. The Level III energy audit is a highly instrumented and long term study. One of our representatives will contact you to discuss. Detailed Analysis of Capital-Intensive Modifications: With mandatory benchmark energy audits required by cities around the U.
Analyze two to three years of utility data electric, gas, water. The audit results in a brief summary report that will detail the findings. Open for public comment until Jan. It may also provide a list of more capital intensive improvements that merit further consideration, and an initial judgment of potential costs and savings.
Depending on the types of systems the building has and the reported problems or issues the building may be experiencing, diagnostics may include any of the following: Leave a comment Cancel comment.

Association for Energy Affordability. All key building representatives owners, managers, operators and occupants are interviewed to gain a thorough understanding of the operational characteristics of the building, to explore all potential problem areas, and to clarify financial and non-financial goals of the assessment.
Dependant on your location and utility service provider!
Also, provide a listing of potential capital improvement that merit further consideration based on costs and potential savings.
It provides detailed project cost and savings calculations with a high level of confidence sufficient for major capital investment decisions. Develop the Energy Utilization Index EUI and compare with similar buildings to determine if further engineering study and analysis are likely buildung produce significant energy savings.
This includes a more detailed building surveyand whole building utility consumption analysis. Open for review and comment until Jan.
Utility rates are analyzed to determine if there are rate change opportunities or if specific utility rate DSM programs are available to the building.
This standard is to establish minimum performance levels for energy audits and bring some order to the chaos. The Level I audit is intended to help the building owner understand where the building performs relative to its peers; establish a baseline for measuring improvements; decide whether further evaluation is warranted; and if so, where and how to focus that effort. The audits can be performed in three levels of complexity and detail: Auditw goal of the new standard is to define audit approaches, information that should be in an audit, and way that information should communicate to the facility manager.

Energy consumption is broken out by end use such that building owners and operators can easily understand which areas of operation may present the greatest opportunities.
