Usage pattern of personal comfort system in office buildings

Analyses occupants’ thermal comfort and the usage pattern of personal comfort system (PCS) in the office environment by subject experiments. Describes the PCS usage pattern by the conditional probability model. Obtains the occupant movement behavior from a field measurement in an office building in Shanghai. Uses the usage model and the movement model to simulate the building environment of the office building, and analyses the energy saving potential of PCS. The results show that the use of PCS can increase the air conditioning set temperature by 2.0 ℃ in summer and reduce by 2.5 ℃ in winter, which reduces the energy consumption of air conditioning cooling and heating by 25% to 40%.
