MIL-HDBK-1133
FOREWORD
The original version of this manual, MO-303, Utilities Target
Manual was last printed in 1972 as a utilities target manual for
energy efficient facilities, and cold iron support for ships
based on design conditions. The manual was developed prior to
the oil embargoes of the late 70's, and there was little interest
in metering tenant commands. As energy consumption became more
of a concern, Navy tenant and Public Works Centers and
Departments (PWC/Ds) became more concerned with tenant
consumption. PWC/Ds began installing steam trunk line, and
electricity meters at the building level. Tenant consumption
estimates were developed using American Society of Heating,
Refrigerating, and Air-Conditioning Engineers Inc. (ASHRAE)
fundamentals, MO-303, and initially limited base level metering.
By derivation, these utility consumption estimates were based on
primarily ideal conditions with some metered data to support it.
More recently PWCs developed software to more fairly distribute
the cost of utilities on a base. The software CUBIC, UUS,
NASSAU, and PWMA are of particular note in the Navy. This
software estimates consumption to varying degrees, using recent
building construction and use, ASHRAE based methods, and are
coupled with some metered data to more fairly estimate tenant
consumption. The software tools given in the table below are
examples of those that can be used to varying degrees, to develop
consumption estimates for unmetered facilities.

OPNAVINST 4100.5, Energy Management directed that all
utility bills be based on metered data. The level of metering is
left open for interpretation. Since metering all utilities at
all buildings is not cost effective, we updated MO-303, based on
a limited statistical sampling of metered data, by building type.
MO-303 presented mathematical formulas, based on the sampled
