MIL-HDBK-1133
buildings is expressed in terms of energy per unit area per unit
time. In this handbook energy metrics used are as follows:
a)
Electricity use is expressed in kilowatt-hours per
square foot per month (kWh/ft2/mo) (in SI units, this is
kilowatt-hours per square meter per month [kWh/m2/mo]).
b)
British thermal units per square foot per month
(kBtu/ft2/mo) (in SI units, this value is expressed in thousand
joules per square meter per month [kJ/m2/mo]).
These EUI values are derived from actual metered energy
consumption data collected at building and overall installation
levels. Table B-1 in Appendix B contains the EUI values and
other adjustment factors for Navy buildings. These EUIs are used
to determine initial energy use values for each building or group
of buildings. Tables 2 and 3 provide examples of the data to be
gathered and calculations to be performed for building electric
and nonelectric energy consumption.
2.2.1
Electric. The following steps define the process for
estimating electrical building energy consumption using the forms
shown in Tables 2 and 3.
a) Enter all metered building data (from utility or
installation meter readings) onto the Table 2 form. Subtotal the
energy consumption by building type. The values account for all
known building energy use and need not be estimated. If metering
equipment or readings are known to be inaccurate, the associated
building energy use should not be included here. A total
consumption estimate for metered buildings can be made by
totaling all building type totals.
b) For buildings where metered data is not available,
subtotal the square footage in the real property database by
Bldg. Type and Group. Enter the Bldg. Type, Group, and Area in
the Table 3 form. Enter the three weather parameters in the
appropriate cells.
