Heating and cooling energy consumptions of 24 h on a representative day of each season simulated by TRNSY are shown in
Fig. 7(a) and (b). Heating and cooling in January 15th of winter
and August 30th of summer were consumed maximally, respectively. Any heating or cooling energy was not consumed in middle
season. In winter, heating systems were operated in the morning
and evening, the length of person’s stay in house and then heating energy consumption was maximal. In summer, cooling systems
were operated in the afternoon influenced by radiation and cooling
energy consumption is significantly increased.
