Abstract

Passive spaces are a passive design strategy that aims to reduce energy ‎consumption ‎and increase ‎user ‎satisfaction ‎in buildings. One ‎example of passive space is ‎the air shaft. The air ‎shaft ‎is a ‎vertical void within the building from the ground level to the roof level, and it ‎provides the ‎building with ‎natural ‎ventilation ‎and ‎daylight, ‎especially in deep-plan ‎buildings. However, ‎the ‎function of the ‎air ‎shaft ‎is ‎questioned ‎due to its impacts on residents’ needs. ‎This ‎study assesses the effects of air ‎shaft ‎specifications on ‎residents’ ‎satisfaction with the indoor ‎environment ‎quality of ‎air shafts and ‎adjoining ‎spaces. Survey ‎questionnaires were ‎distributed ‎to ‎residents of ‎apartment ‎buildings. The results ‎proved that air shafts ‎have a ‎significant ‎negative ‎impact on ‎residents’ ‎satisfaction. The ‎findings of cross-tabulation ‎analysis illustrate a significant ‎relationship ‎between ‎the air ‎shafts’ specifications and ‎the ‎residents’ answers.‎ The ‎analysis also showed that the air ‎shafts ‎that are ‎closed from the ‎bottom and include A\C outdoor units ‎have a more negative ‎impact on ‎the thermal ‎environment and ‎air quality. Regarding ‎the air shaft areas, the small areas have ‎a ‎high ‎negative ‎response regarding bad smell, the view, visual ‎and ‎acoustic privacy, and thermal ‎environment. ‎From ‎the ‎indoor ‎environment quality perspective, this ‎study ‎emphasizes ‎the need ‎to consider the ‎impact of ‎air ‎shaft design on a ‎building’s ‎performance ‎and ‎residents’ ‎satisfaction. The results of this study are expected to contribute to the development of future passive spaces design.
