What are the three levels of ASHRAE energy audits?

Solution

The three levels of ASHRAE energy audits are

(i) Walk-Through Analysis/Preliminary Audit

(ii) Energy Survey and Analysis

(iii) Detailed Analysis of Capital Intensive Modifications.

Walk-Through Analysis/Preliminary Audit : The level 1 audit is also called as screening audit ,simple audit or walk-through audit the Walk-Through Analysis/Preliminary Audit is the most basic audit. It involves brief interviews with site operating personnel, and a review utility bills and other operating data. The main aim of ASHRAE energy audit level 1 is towards the identification of energy waste. The ASHARE level 1 audit provides a brief corrective measures which has to be taken for utilisation of energy and also it provides a brief information of implementation cost and simple payback periods are also provided.But ASHRAE energy audit level 1 will not cover the major problem areas.

Energy Survey and Analysis: A Level 2 ASHRAE energy audit consists of preliminary ASHRAE Level 1 analysis and also it includes more detailed energy calculations such as Lighting, Heating, Ventilation energy calculations and also financial analysis of proposed energy efficiency measures.

Detailed Analysis of Capital Intensive Modifications: The Level 3 ASHRAE energy audit is also known technical analysis audit ,comprehensive audit or detailed audit. The main aim of a Level 3 ASHRAE energy audit is identification and focus on the potential capital-intensive projects which are identified in the Level 2 analysis . The Level 3 ASHRAE energy audit also provides detailed project cost and savings calculations. investment decisions.
