Nowadays office environment that could increase workers' productivity is expected to be designed. Task/ambient conditioning system (TAC) is one of the systems that could remove local heat load effectively and create his/her preferred thermal environment. Subjective experiments with TAC were conducted to investigate the impact of TAC on occupants with regard to their productivity in a climate chamber and a real office environment. Results showed that TAC could contribute to increase their productivity. However, to know the real performance of TAC on productivity, further investigation on evaluation methods will be required.
