mechanical systems performance analysis and therefore took into account consumption

data for four major resources; water, steam, chilled water, and electricity. Consumption

data was acquired through assistance from the University Florida Energy Office. While

these four utilities do not represent a truly complete building analysis, they provide an

accurate representation of performance efficiency. The results were then qualified based

on average hours of building operation, and total horsepower of each building's

mechanical systems.

 Life-Cycle Cost Analysis

 The life-cycle costing analysis is a quantifiable determination of true cost of

ownership, calculated within a standard Microsoft Excel Spreadsheet. The purpose of

life-cycle costing is to analyze costs over a realized life of a building, and translate those

costs into current dollars. Contrary to simply averaging costs and realizing annual

expenditures, a life-cycle costing system will adjust for inflation and escalation, and

allow for more accurate decision making by taking future factors into account. This

particular life-cycle costing system will directly compare Rinker Hall with each

additional building through separate analysis for each. Either Anderson, or Frazier

Rogers Hall will serve as the control portion of the comparison, while Rinker Hall will be

presented as the variable. The added costs for the sustainable initiatives in the Rinker

Hall mechanical systems will be carried in the up-front cost portion of the life-cycle

spreadsheet for Rinker, while the other buildings will show zero up-front cost. The

annual total for each individual utility is then entered for each respective building as the

annual costs. The sum of these costs over a 20 year period is adjusted for such factors as

price escalation, inflation, and discount rate, then presented in equivalent current dollars
