| Outline of Final Research Achievements |
The authors performed a field survey on occupants' behavior toward the use of air-conditioners (A/C) in residential buildings in Malaysia in order to establish methodologies for estimating the stochastic time patterns of energy demand in tropical climate. Temperatures of room air and outlet of A/C were measured in 60 dwellings every 15 minutes, and converted into the information of when occupants turned on/off the A/C.
Based on the analysis of the measured data, it was revealed that the occupants behavior toward A/C use in Malaysia can not be modeled by the current Markov-model developed in mid-latitude countries, which adopts a sigmoid function for expressing the probability of A/C off-on behavior with an input variable of indoor thermal condition, such as room air temperature owing to the difference of the climate. With this finding, the authors established a new algorithm for generating stochastic A/C operation schedule based on the statistics of the measurement.
