Based on the investigation on the intelligent office buildings in Taiwan, the gradings among different buildings are compared in terms of the building location, the type of operation, and the size of building. Factors influencing the grading scores are evaluated according to the comparison results. In addition, the attitude of the building occupants toward the intelligent office building itself is also surveyed based on the performance of the building facilities, the willingness to install the automated devices, and the degree of satisfaction about the overall working environment provided by the intelligent building. The findings form this research can be useful for the planning, the design, and the operation of the intelligent office buildings in Taiwan.
