Ohio Laws and Rules
(A) During the development of the preliminary building schematic, the designer shall:
(1) Develop at least three practical alternative design concepts, considering passive and/or active building components, for the purpose of minimizing future energy consumption.
(2) Estimate the annual energy consumption and associated energy costs of each alternative, analyze their impact on building life-cycle costs and incorporate into the final building design alternatives which are cost effective in accordance with paragraph (B) of rule 123:4-1-03 of the Administrative Code.
(3) Re-evaluate life-cycle cost as additional alternatives are considered during the continuing design development to assure their cost effective implementation.
(4) Supply all pertinent data summarizing the life-cycle analysis to the office of the state architect for review and evaluation.
(B) After the completion of the building’s design development an energy consumption analysis shall be performed for the purpose of estimating the expected energy consumption and associated cost of the proposed facility in accordance with paragraph (C) of rule 123:4-1-03 of the Administrative Code.
Supply all pertinent energy consumption data to the office of the state architect for review and evaluation. These data shall include but not be limited to:
(1) Expected annual energy usage and initial cost by energy type.
(2) Distribution of expected energy consumption by major building systems.
(3) Energy performance index of the proposed design.
(C) The energy consumption calculations shall be performed in accordance with established engineering practices and currently accepted methodology including computerized simulation techniques approved by the state architect.
(D) The following economic methodological assumptions shall be utilized in computing life-cycle costs:
(1) The study period shall consider the number of years during which the proposed facility is not expected to undergo major renovation or major changes in utilization.
(2) Future costs shall not include adjustments for general inflation but shall include incremental adjustments which are above or below the general inflation rate.
(3) The time value or alternative investment value of money shall be considered by discounting future cost to present value. The discount rate shall be in accordance with generally accepted practices.
