Association for Energy Affordability. The site commecial may include a variety of diagnostic testing. This standard is to establish minimum performance levels for energy audits and bring some order to the chaos. In addition to the energy model, the energy engineer will also generate an audit report that thoroughly documents building conditions, operational characteristics, and proposed energy savings measures. Detailed Analysis of Capital-Intensive Modifications: It will also list any potential capital-intensive improvements that require more thorough data collection and engineering analysis Level III Auditand a preliminary judgment of potential costs and savings associated with those improvements.
The high resolution data that is collected enables us to perform calculations that commfrcial be used to very accurately predict energy and cost savings.
Depending on buildibg types of systems the building has and the reported problems or issues the building may be experiencing, diagnostics may include any of the following: With mandatory benchmark energy audits required by cities around the U. Preliminary Energy Use Analysis: Utility rates are analyzed to determine if there are rate change opportunities or if specific utility rate DSM programs are available to the building.
Leave a comment Cancel comment. It provides detailed project cost and savings calculations with a high level of confidence sufficient for major capital investment decisions.
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. Analyze two to three years of utility data electric, gas, water.
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. Proceures Evaluation Results in: It may also provide a list of more capital intensive improvements that merit further consideration, and an initial judgment of potential costs and savings. Develop the Energy Utilization Index EUI and compare with similar buildings to determine if further engineering study and analysis are likely to produce significant energy savings.
Open for review and comment until Jan. The Level III audit is typically reserved for complex commercial and industrial buildings with very specific and accurate economic payback analysis requirements. In the interest of considering the narrowing distance between comparable standards and methods for energy performance i.
The goal sahrae the new standard is to define audit approaches, information that should be ahrae an audit, and way that information should communicate to the facility manager. The Level III energy audit is a highly instrumented audkts long term study.

These procedures for conducting audits are accepted as the industry gold standard and proven to be effective for any size project.
This includes a more detailed building surveyand whole building utility consumption analysis. 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 audit results in a brief summary report that will detail the findings. Open for public comment commercal Jan. 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.
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. Energy Survey and Engineering Analysis:
