   Subpart A--Methodology and Procedures for Life Cycle Cost Analyses
 
Sec. 436.11  Definitions.

    As used in this subpart--
    Base Year means the fiscal year in which a life cycle cost analysis 
is conducted.
    Building energy system means an energy conservation measure or any 
portion of the structure of a building or any mechanical, electrical, or 
other functional system supporting the building, the nature or selection 
of which for a new building influences significantly the cost of energy 
consumed.
    Building water system means a water conservation measure or any 
portion of the structure of a building or any mechanical, electrical, or 
other functional system supporting the building, the nature or selection 
of which for a new building influences significantly the cost of water 
consumed.
    Component price means any variable sub-element of the total charge 
for a

[[Page 622]]

fuel or energy or water, including but not limited to such charges as 
``demand charges,'' ``off-peak charges'' and ``seasonal charges.''
    Demand charge means that portion of the charge for electric service 
based upon the plant and equipment costs associated with supplying the 
electricity consumed.
    DOE means Department of Energy.
    Energy conservation measures means measures that are applied to an 
existing Federal building that improve energy efficiency and are life 
cycle cost effective and that involve energy conservation, cogeneration 
facilities, renewable energy sources, improvements in operation and 
maintenance efficiencies, or retrofit activities.
    Federal agency means ``agency'' as defined by 5 U.S.C. 551(1).
    Federal building means an energy or water conservation measure or 
any building, structure, or facility, or part thereof, including the 
associated energy and water consuming support systems, which is 
constructed, renovated, leased, or purchased in whole or in part for use 
by the Federal government. This term also means a collection of such 
buildings, structures, or facilities and the energy and water consuming 
support systems for such collection.
    Investment costs means the initial costs of design, engineering, 
purchase, construction, and installation exclusive of sunk costs.
    Life cycle cost means the total cost of owning, operating and 
maintaining a building over its useful life (including its fuel and 
water, energy, labor, and replacement components), determined on the 
basis of a systematic evaluation and comparison of alternative building 
systems, except that in the case of leased buildings, the life cycle 
cost shall be calculated over the effective remaining term of the lease.
    Non-fuel operation and maintenance costs means material and labor 
cost for routine upkeep, repair and operation exclusive of energy cost.
    Non-recurring costs means costs that are not uniformly incurred 
annually over the study period.
    Non-water operation and maintenance costs mean material and labor 
cost for routine upkeep, repair and operation exclusive of water cost.
    Recurring costs means future costs that are incurred uniformly and 
annually over the study period.
    Replacement costs mean future cost to replace a building energy 
system or building water system, an energy or water conservation 
measure, or any component thereof.
    Retrofit means installation of a building energy system or building 
water system alternative in an existing Federal building.
    Salvage value means the value of any building energy system or 
building water system removed or replaced during the study period, or 
recovered through resale or remaining at the end of the study period.
    Study period means the time period covered by a life cycle cost 
analysis.
    Sunk costs means costs incurred prior to the time at which the life 
cycle cost analysis occurs.
    Time-of-day rate means the charge for service during periods of the 
day based on the cost of supplying services during various times of the 
day.
    Water conservation measures mean measures that are applied to an 
existing Federal building that improve the efficiency of water use, 
reduce the amount of water for sewage disposal and are life cycle cost 
effective and that involve water conservation, improvements in operation 
and maintenance efficiencies, or retrofit activities.
