Energy & Green Bldg Audit

An energy audit is a systematic approach to problem solving and decision making. The primary goals of an energy audit are to qualify and quantify how the building energy systems are performing now, how that performance can be improved, and what will be the outcomes of those improvements for the Owner in financial and non-financial terms.
Energy audits vary in depth, depending on the configuration of the building energy systems, the project parameters set by the client, and the scope and capabilities offered by the energy auditor. Because it usually is not possible to know where the audit process will lead and what level of effort will be most cost effective, ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) has defined three progressive levels, or types, of audits

Energy Audits Levels

There are three Levels of Energy Auditing for Commercial and Institutional Buildings. The  table below summarizes each level.

Audit Type


Level 1

  • Rapid assessment of building energy systems
  • Building energy benchmark
  • High-level definition of energy system optimization opportunities Outline applicable incentive programs

Level 2

  • Detailed building survey of systems and operations
  • Breakdown of energy source and end use
  • Identification of EEMs for each energy system
  • Range of savings and costs for the EEMs
  • Spotlight on Operational Discrepancies
  • Outlining priorities for limited resources, next steps, and identification of EEMs requiring more thorough data collection and analysis (ASHRAE Level-3)

Level 3

  • Longer term data collection and analysis
  • Whole-building computer simulation calibrated with field data
  • Accurate modeling of EEMs and power/energy response
  • Bid-level construction cost estimating
  • Investment-grade, decision-making support

EEG approach

EEG follows diligently the ASHRAE Procedures for Commercial Building Energy Audit and its standard reports are in between the above Levels II and III.

Our energy auditing team is composed fully of Certified Energy Managers (CEM) who are totally versed in the company's approach of providing every project its needed 'extra miles'  and customzed solution as energy audits' outcomes and results closely depend on the experience of the auditors along their in depth and holistic look of every details in the facility.

EEG's vision on energy auditing and why ' Not all energy audits are born equal' are depicted in this post.
