Preliminary energy use analysis.
Ashrae energy audit level 2.
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.
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 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.
The following list is a brief description of the steps performed for the level 2 audit.
All three levels of audits require a preliminary energy use analysis which involves the following.
Procedures for commercial building energy audits second edition available in print or.
Ashrae standard 211 2018 standard for commercial building energy audits topic references energy audit level 1 2 3 walk through energy survey cognizant ashrae committees refer to organization.
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.
The level 2 process is designed to follow the level 1 audit.
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.
The next step for most facilities is the ashrae level 2 audit assessment.
Ashrae level 2 energy survey and analysis.
Establishes guidelines for levels 1 2 and 3 of audit effort.
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.
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 audit process.
Each audit level builds on the previous level.
Shows how to conduct effective energy audits that lead to actionable audit reports.
Funding an energy audit the scope and level of detail of the energy audit can be a big driver in costs.
Ashrae 2 defines three levels of audits.
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.
