CIRA is a user-friendly, microcomputer-based energy analysis and retrofitting tool for residential buildings. CIRA can develop a monthly analysis of heating, cooling and appliance use, as well as a list of retrofits, ordered by decreasing savings-to-cost ratio, for any house and any climate specified by the user. The list stops when no retrofits with a positive economic return remain or when a preset budget is reached, whichever comes first. The approaches used in CIRA to deal with a number of well-known problems inherent in economic optimization of buildings, such as: (1) interactions among retrofits; (2) handling of mutually exclusive retrofits; (3) decreasing marginal returns as more retrofits are installed; and (4) constraints on computer time and memory are presented.
