Rachel asks: What is definition of energy audit level 3? I am looking for a bid template/example of a thorough energy audit - level 3 audit. Can you help me??
Rachel, with the ARRA money coming into distribution in states across the country, terms like this are finding their ways into requests for proposals more and more. Throw into the mix the push to save energy as well as programs like Energy Star and USGBC’s LEED as well as commissioning and energy audits are becoming more and more prevalent in the industry.
As a mechanical design engineer, my understanding of the three energy audit levels is as defined by the ASHRAE Handbook, HVAC Applications, Chapter 35: Energy Use and Management. There are three levels of Energy Audits. Preliminary Energy Use Analysis, Level I – Walk-Through Assessment, Level II – Energy Survey and Engineering Analysis, and Level III – Detailed Analysis of Capital-Intensive Modifications. So each new level builds on the information from the previous level.
From the ASHRAE Handbook…
While there are plenty of checklists and how to guides for ‘do it yourself’ energy audits, these tend towards the residential side (learn more here), while the ASHRAE energy audit levels include an underlying assumption of implementation in a commercial building.
Even with these definitions, there’s some room for interpretation – each individual engineer might draw the line between Level I and Level II services differently as well, so it’s somewhat subjective.
Hope this helps,
