Ashrae 2 defines three levels of audits.
Ashrae energy audit level 2.
Procedures for commercial building energy audits second edition available in print or.
Funding an energy audit the scope and level of detail of the energy audit can be a big driver in costs.
Establishes guidelines for levels 1 2 and 3 of audit effort.
The level 2 project starts with the findings of the level 1 audit and evaluates the building energy systems in detail to define a variety of potential energy efficiency improvements.
If you spend 10 000 on an ashrae level 2 audit that finds energy savings potential of 5000 then you overpaid for the audit and probably should have gotten an ashrae level 1 audit.
Ashrae level 2 energy survey and analysis.
Shows how to conduct effective energy audits that lead to actionable audit reports.
The building s energy consumption is broken down by end use helping to identify the areas with the greatest opportunities for improved efficiency.
A guide to energy audits 2 what is an energy audit.
All three levels of audits require a preliminary energy use analysis which involves the following.
Ashrae level 2 audit energy survey analysis a level 2 audit begins with everything in a level 1 audit but takes the data collection and final reporting a step farther.
Includes more than 25 guideline forms plus access to the forms in spreadsheet format for easy customization.
A level 2 audit includes the preliminary ashrae level 1 analysis but also includes more detailed energy calculations and financial analysis of proposed energy efficiency measures.
The following list is a brief description of the steps performed for the level 2 audit.
The level 1 2 and 3 ashrae auditing standards focus on the identification of the potential for energy efficiency improvements understanding the overall building configuration and defining the type and nature of energy systems.
Ashrae level 2 energy audit an ashrae level 2 energy audit is the most popular type widely available and is useful for evaluating and developing most energy projects lighting measures and controls basic hvac measures motor upgrades including variable frequency drive applications replacement of inefficient equipment with energy efficient alternatives building envelope measures.
Each audit level builds on the previous level.
The next step for most facilities is the ashrae level 2 audit assessment.
The level 2 process is designed to follow the level 1 audit.
Preliminary energy use analysis.
The level 2 report details the opportunities to such a degree that actual decisions on implementation can be made and the leed eb credit can be realized.

As audit complexity increases so does thoroughness of the site assessment.
