by the facility/plant manager, and should be arranged so the auditor
or audit team can see the major operational and equipment to obtain
general information. More specific information should be obtained from
the maintenance and operational people after the tour.
Getting Detailed Data
Following the facility or plant tour, the auditor or audit team
should acquire the detailed data on facility equipment and operation
that will lead to identifying the significant energy conservation oppor-
tunities (ECOs) that may be appropriate for this facility. This includes
data on lighting, HVAC equipment, motors, and water heating, as well
as specialized equipment such as refrigerators, ovens, mixers, boilers,
heaters, etc. These data are most easily recorded on individualized data
sheets that have been prepared in advance.
What to Look for
- Lighting: Making a detailed inventory of all lighting is impor-
tant. Data should be recorded on the numbers of each type of
light fixtures and lamps, wattages of lamps, and hours of opera-
tion of groups of lights. A lighting inventory data sheet should
be used to record these data. Using a lightmeter, the auditor
should also record light intensity readings for each area. Taking
notes on types of tasks performed in each area will help the au-
ditor select alternative lighting technologies that might be more
energy efficient. Other items to note are the areas that may be
infrequently used and may be candidates for occupancy sensor
controls of lighting. Areas where daylighting may be feasible
should also be considered. - HVAC Equipment: All heating, air conditioning and ventilating
equipment should be inventoried. Prepared data sheets can be
used to record type, size, model number, age, electrical specifi-
cations, or fuel use specifications, as well as estimated hours of
operation. The equipment should be inspected to determine the
condition of the evaporator and condenser coils, the air filters, and
the insulation on the refrigerant lines. Air velocity measurement
may also be made and recorded to assess operating efficiencies
or to discover conditioned air leaks. These data will allow later
