For energy conservation and CO2 emission reduction, renewable energy facilities, such as solar equipments and rooftop gardens, are considered effective for energy management of institutional buildings in a community. This study integrated an energy mixture facility model with a nondominated sorting genetic algorithm-II optimizer as a multiobjective optimal facility allocation model (MOFAM) for allocating renewable energy facilities on the rooftop of campus buildings. A case study was conducted on a college campus to demonstrate the feasibility of MOFAM. MOFAM offers simple steps and provides more allocation plans to satisfy decision-makers' requirements for minimum investment cost, maximum CO2 reduction, and maximum investment returns. In addition, the result demonstrates that the multiobjective optimal model considering three objectives resulted in optimal solutions that include the optimal solutions generated from two-objective optimization. In this campus case, MOFAM helped decision-makers optimize the installation area of solar photovoltaic panels, the installation area of solar water heaters, and the area of rooftop gardens on campus rooftops to perform effective management for institutional buildings for conserving energy and CO2 reduction.
