Energy Audit

An Energy Audit is an evaluation of a building and its energy equipment to determine the costs and potential savings of energy efficient measures that can be implemented to reduce energy consumption and includes the following:

Level I – The Walk-Through Audit

• Conduct a walk-through of the facility to inspect each of the energy using systems.
• Evaluate energy consumption data and analyze energy use and patterns and comparisons to industry averages or benchmarks for similar facilities
• Give preliminary estimate of savings potential
• Provide a list of cost saving opportunities through improvements in operational and maintenance practices
• Provides opportunity to collect information for a more detailed audit, subsequently, if preliminary savings potential warrant an expanded scope of auditing assessment.

Level II – Standard Audit (also includes)

• Quantify energy uses and losses through a detailed review and analysis of equipment, systems, and operational characteristics
• Conduct, if necessary, on-site measurements and testing to quantify energy use and efficiency of various systems
• Use standard energy engineering calculations to analyze efficiencies and calculate energy and costs savings based on improvements and changes to each system
• Conduct economic analysis of recommended conservation measure.

Level III – Computer Simulation (also includes)

• Use of computer simulation software that includes more detailed of energy use by function and a more comprehensive evaluation of energy use patterns
• Develop a computer simulation of building systems that will account for weather variables and predict year round energy use that can be used to build a base for comparison that is consistent with the actual energy consumption of the building
• Measure the effects of changes that are made to the baseline simulation which can improve efficiencies of various systems; accounts for interactions between systems to help prevent overestimation of savings.
• Most expensive level of audit due to the time involved in collecting detailed equipment information, operational data, setting up and accurate, computer model.

Provide an initial verbal report to you summarizing the overall impressions of the facility within 24 hours of the site visit and provide a written report.
