GENERAL FLOWCHART INTRODUCTION
This flowchart illustrates the complete set of procedures necessary for an
industrial energy audit. The process is broken down into three subsections: the pre-audit,
the audit walkthrough and post audit, and the evaluation of savings. Simply browsing
through the components of the flow chart, the user can become familiar with the general
procedures involved in an energy audit. However, the flow chart serves a much greater
purpose than simply illustrating a process or set of procedures. Each component of the
flow chart is linked to important documents needed to actually carry out an audit, rather
than just learn about it. Clicking on various shapes of the flowchart will lead the user to
help documents, informational websites, audit documents, utility calculator excel sheets,
checklists of things to look for, and so on. Bringing all this information into one
convenient location means less time must be spent on organizing information and
preparing for an audit.
The first page of the flow chart shows the highest level overview of the process,
broken down into its three subsections. The legend details what type of activity or tool
each flowchart shape represents. Clicking on the various flowchart components leads to
flowcharts for the rest of the audit process.
For those unfamiliar with the energy audit process, here is a brief break down.
The IAC starts by finding a small to medium-sized manufacturing facility looking to
improve its energy efficiency and save money on energy usage. The process begins by
asking a plant manager or other highly informed employee to complete a pre-audit form
detailing information about energy usage in the facility. The members of the IAC use this
information to become familiar with what goes on at that particular facility and conduct
the pre-audit analysis. From here, IAC members are assigned tasks for the audit
walkthrough, such as analyzing the compressed air system throughout the entire facility.
Members must then try to become experts in their task area.
During the walkthrough audit, which takes place over the course of one day, the
audit checklists are used to gather all the necessary data to analyze the energy
consumption of the plant. The data gathered here is compared with best practices to
determine where improvements can be implemented and savings can be realized.
Finally, a formal post-audit write up is created and presented to the facility within
60 days. After a few months,, follow up visits or communication with the facility allow
the IAC to gain feedback on how the plant is performing.
