Systems Engineering was applied to Terraset, a school underground, heated and cooled via the sun. The Systems Engineering process (since it occurred after design) consisted of Needs Analysis, Functional Analysis, Test Requirements Analysis and System Life Cycle Cost Analysis. The school had never been Systems Engineered and the processes revealed a long list of requirements still lacking. The results of the thesis are applicable to a new design taking place at the Burke Center Elementary School. / M.S.
