A guide to energy audits 2 what is an energy audit.
Ashrae level 2 energy audit.
The ashrae level i audit or walk through audit is the basic starting point for building energy optimization.
The following list is a brief description of the steps performed for the level 2 audit.
Preliminary energy use analysis.
The level 2 process is designed to follow the level 1 audit.
Procedures for commercial building energy audits second edition available in print or.
Shows how to conduct effective energy audits that lead to actionable audit reports.
Includes more than 25 guideline forms plus access to the forms in spreadsheet format for easy customization.
The ashrae level i audit is intended to be a quick assessment.

The next step for most facilities is the ashrae level 2 audit assessment.
It consists of an initial review of the property s utility bills and a brief site survey of the building its systems and its modes of operation.
The building s energy consumption is broken down by end use helping to identify the areas with the greatest opportunities for improved efficiency.
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.
Ashrae level 2 energy survey and analysis.
Each audit level builds on the previous level.
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 2 defines three levels of audits.
Establishes guidelines for levels 1 2 and 3 of audit effort.
Ashrae level i audit.
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.
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.
All three levels of audits require a preliminary energy use analysis which involves the following.
Funding an energy audit the scope and level of detail of the energy audit can be a big driver in costs.
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.
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.
