This protocol applies to government/public-owned and/or -operated nonindus-
trial and industrial facilities. The energy assessment described in the protocol
addresses major energy sources and areas of end use, including
Building envelope ■
HVAC and automation systems and their operation ■
Central energy plants with heat and chilled water distribution systems ■
Water supply systems ■
Compressed air systems ■
Lighting systems ■
Internal loads (motors, drives, etc.) ■
Production processes ■
Control strategies ■
1.1 Special Features of Industrial Sites
Industrial energy assessment shall focus on site-specifi c, critical cost issues, which if
solved, will make the greatest possible economic contribution to a facility’s bottom
line. Major potential costs issues include capacity utilization (bottlenecks), material
utilization (off spec, scrap, rework), labor (productivity, planning, and scheduling),
energy (steam, electricity, compressed air), waste (air, water, solid, hazardous),
equipment (outdated or state of the art), and so forth.
From a strict cost perspective, process capacity, materials, and labor uti-
lization can be far more signifi cant than energy and environmental concerns.
All of these issues, however, must be considered together to affect the facility
mission in the most effi cient and cost-effective way.
Therefore, there may be two ways to approach the problem:
If the general costs are too high (or if the building needs renovation 1.
anyway) one should start a cost assessment and an energy assessment (as
part of the cost assessment). This renews the processes and also (with
little extra money) can achieve an energy optimization.
