Reduction of energy consumption by AC due to air tightness and ventilation strategy in residences in hot and humid climates

This paper proposes strategies for reducing energy consumption for cooling in residences in hot and humid climates.Based on the results of fieldwork measurements and questionnaire surveys, a simulation of indoor thermal environments in consideration of AC operation was carried out, in order to evalu...
