The Investigation of the Interior Environment of the Complicated High-Density Shophouse in Khlong-Toei Market Community, Bangkok, Thailand

抄録

Klong Toey Market, a densely populated area in Thailand, has attracted many newcomers due to high labor demand. Shophouses and markets were constructed around the harbor to facilitate goods distribution, serving residences to workers. However, many of these shophouses are now deteriorating, negatively impacting residents’ living environments. This research aims to provide insights for owners and residents of shophouses, fostering awareness of current environmental conditions. The goal is to collaboratively develop solutions to improve housing quality. With many older shophouses in existence, a deeper understanding of maintenance and enhancement strategies is crucial for creating healthier living environments that align with contemporary lifestyles. In this study, the actual condition of the shophouse was clarified by detailed actual measurements and grasp the difficult situation of the living environment. Subsequently, data on the physical and interior environments of shophouses were collected, including temperature, relative humidity, carbon dioxide levels, and lighting, to identify specific issues. It was found that high temperatures typically coincide with lower relative humidity and elevated carbon dioxide concentrations, while high humidity can hinder air density, complicating carbon dioxide dispersion. Notably, high humidity can lower temperatures but create a sensation of warmth, underscoring the need for comprehensive data management due to the interrelated nature of these factors. The analysis emphasizes that natural air movement and ventilation are crucial for regulating conditions within shophouses. Carbon dioxide levels can vary significantly in areas with the same temperature, particularly where ventilation is poor. Enhancing natural ventilation can improve carbon dioxide dispersion, temperature control, and reduce excess moisture, ultimately increasing resident comfort. This research contributes to a broader effort toward resilient urban housing in high-density contexts.
