Enhancing Energy Conservation, Visual and Thermal Comfort in Small Houses of Karachi
Abstract
Abstract Views: 0
The significance of housing in developing cities cannot be overstated, as individuals strive to acquire and own physical assets throughout their lives, even in the case of small plots as modest as 80 square yards. In urban areas such as Karachi, smaller houses ranging from 80 to 240 square yards mostly are predominantly constructed by contractors or by owners themselves. This is to avoid additional fees charged by architects who may tailor the design to suit the context and specific requirements. Consequently, these houses tend to exhibit a similar layout, maximizing the utilization of allowable space as stipulated by the bylaws. However, this approach often leads to limited natural ventilation and daylighting, resulting in increased energy consumption for thermal and visual comfort. Hence, the current research underscores the urgency of addressing the prevailing lack of natural ventilation and daylighting in these houses. To address these concerns, it presents a comprehensive framework of passive strategies aimed at enhancing the thermal and visual comfort of occupants. Firstly, an archival study was conducted, encompassing a comprehensive literature review, which served as a foundation to understand the subject matter. Secondly, a comparative study was undertaken to examine conventional small house typical plans prevalent in Karachi. This study was followed by the formulation of proposals for improved planning. Various secondary resources were utilized to support the comparative analysis of two typical house plans in Karachi, in conjunction with the proposed passive strategies. Through the application of these strategies, occupants can benefit from improved comfort, reduced energy consumption, and heightened well-being.
