The Facility Survey
The survey of the facility is considered a very important part of the industrial energy audit. Chapter 1 indicated that there are many types of surveys, from a simple walk-through to a complete quantification of uses and losses. This chapter will illustrate various types of instruments that can aid in the industrial audit.

COMPARING CATALOGUE DATA WITH ACTUAL PERFORMANCE
Many energy managers are surprised when they record actual performance data of equipment and compare it with catalogue information. There is usually a great disparity between the two.
Each manufacturer has design tolerance for its equipment. For critical equipment, performance guarantees or tests should be incorporated into the initial specifications.
As part of the facility survey, nameplate data of pumps, motors, chillers, fans, etc., should be taken. The nameplate data should also be compared to actual running conditions.
The initial survey can detect motors that were sized too big. By replacing the motor with a smaller one, energy savings can be realized.

INFRARED EQUIPMENT
Some companies may have the wrong impression that infrared equipment can meet most of their instrumentation needs. The primary use of infrared equipment in an energy utilization program is to detect building or equipment losses. Thus it is just one of the many options available.
