470.2 POLICY -- ANALYSIS REQUIRED.
The general assembly declares that energy management is of primary
importance in the design of publicly owned facilities. Commencing
January 1, 1980, a public agency responsible for the construction or
renovation of a facility shall, in a design begun after that date,
include as a design criterion the requirement that a life cycle cost
analysis be conducted for the facility. The objectives of the life
cycle cost analysis are to optimize energy efficiency at an
acceptable life cycle cost. The life cycle cost analysis shall meet
the requirements of section 470.3. Section History: Early Form
[C81, § 470.2]
470.3 ELEMENTS OF ANALYSIS.
1. A life cycle cost analysis shall include but is not limited to
the following elements:
a. Specification of energy management objectives and health,
safety, and functional constraints. The facility design shall comply
with applicable state or local building code requirements.
b. Identification of the energy needs of the facility and
energy system alternatives to meet those needs.
c. Cost of the energy system alternatives identified in
paragraph "b" of this subsection.
d. Determination of amounts and timing of cash flow.
e. Calculation of life cycle cost using an economic model
such as, but not limited to, rate of return, annual equivalent cost
or present equivalent cost.
f. Evaluation of design and system alternatives using a
method such as, but not limited to, design matrixes, ranking tables,
or network analysis.
2. A public agency or a person preparing a life cycle cost
analysis for a public agency shall consider the methods and
analytical models provided by the office and available through the
commissioner, which are suited to the purpose for which the project
is intended. Within sixty days of final selection of a design
architect or engineer, a public agency, which is also a state agency
under section 7D.34, shall notify the commissioner and the office of
the methodology to be used to perform the life cycle cost analysis,
on forms provided by the office. Section History: Early Form

470.4 ANALYSIS APPROVED.
The life cycle cost analysis shall be approved by the public
agency before contracts for the construction or renovation are let.
A public agency may accept a facility design and shall meet the
requirements of this chapter if the design meets the operational
requirements of the agency and provides the optimum life cycle cost.
The public agency shall retain a copy of the life cycle cost analysis
and a statement justifying a design decision both of which shall be
available for public inspection at reasonable hours. Section History: Early Form
[C81, § 470.4]
470.5 EXCEPTIONS.
This chapter does not apply to buildings used on January 1, 1980
by the division of adult corrections of the department of human
services as maximum security detention facilities or to the
renovation of property nominated to, or entered in the national
register of historic places, designated by statute, or included in an
established list of historic places compiled by the historical
division of the department of cultural affairs. Section History: Early Form

470.6 RESTRICTION ON USE OF PUBLIC FUNDS.
Public funds shall not be used for the construction or renovation
of a facility unless the design for the work is prepared in
accordance with this chapter and the actual construction or
renovation meets the requirements of the design. Section History: Early Form
[C81, § 470.6]
470.7 LIFE CYCLE COST ANALYSIS -- APPROVAL.
1. The public agency responsible for the new construction or
renovation of a public facility shall submit a copy of the life cycle
cost analysis for review by the commissioner who shall consult with
the office. If the public agency is also a state agency under
section 7D.34, comments by the office or the commissioner, including
any recommendation for changes in the analysis, shall, within thirty
days of receipt of the analysis, be forwarded in writing to the
public agency. If either the office or the commissioner disagrees
with any aspects of the life cycle cost analysis, the public agency
affected shall timely respond in writing to the commissioner and the
office. The response shall indicate whether the agency intends to
implement the recommendations and, if the agency does not intend to
implement them, the public agency shall present its reasons. The
reasons may include but are not limited to a description of the
purpose of the facility or renovation, preservation of historical
architectural features, architectural and site considerations, and
health and safety concerns.
2. Within thirty days of receipt of the response of the public
agency affected, the office, the commissioner, or both, shall notify
in writing the public agency affected of the office's, the
commissioner's, or both's agreement or disagreement with the
response. In the event of a disagreement, the office, the
commissioner, or both, shall at the same time transmit the
notification of disagreement with response and related papers to the
executive council for resolution pursuant to section 7D.34. The life
cycle cost analysis process, including submittal and approval, and
implementation exemption requests pursuant to section 470.8, shall be
completed prior to the letting of contracts for the construction or
renovation of a facility. Section History: Recent Form

470.8 LIFE CYCLE COST ANALYSIS -- IMPLEMENTATION AND
EXEMPTIONS.
The public agency responsible for the new construction or
renovation of a public facility shall implement the recommendations
of the life cycle cost analysis.
The commissioner, in consultation with the director, shall, by
rule, develop criteria to exempt facilities from the implementation
requirements of this section. Using the criteria, the commissioner,
in cooperation with the director, shall exempt facilities on a case
by case basis. Factors to be considered when developing the
exemption criteria shall include, but not be limited to, a
description of the purpose of the facility or renovation, the
preservation of historical architectural features, site
considerations, and health and safety concerns. The commissioner and
the director shall grant or deny a request for exemption from the
requirements of this section within thirty days of receipt of the
request. Section History: Recent Form
