Sustainable Building Assessment of Colonial Shophouses after Adaptive Reuse in Kuala Lumpur

et al. 2017

Kuala Lumpur, as a major capital city, has undergone a drastic transformation in the past ten years. Many heritage buildings have been sacrificed for urban renewal projects. Those located in the touristic heritage zones within Kuala Lumpur were being converted by their owners into hotels and cafés to meet current demands to sustain their incomes. This approach, however, creates several physical and environmental issues within the new adaptation. The aim of this study is to evaluate the building performance of heritage shophouses that were adapted into budget hotels. The research focuses on two case studies in a strategic and historical location of Jalan Sultan, Kuala Lumpur. At the initial stage, interviews and physical surveys were done to determine the context of this study. The authors of this research then used a triangulation method through indoor environmental condition assessment, measurements of indoor environmental conditions and occupant survey to determine the indoor building performance after the adaption. Results showed that adaptive reuse heritage buildings can perform and meet new indoor environmental requirements, but many sensitive design judgments need to be made before the adaptive reuse renovation. The research found that the use of natural light, natural ventilation, recycled materials and water efficiency have been neglected and thus, they should be prioritized and preserved to ensure a successful change of use. Conserving existing heritage buildings, while incorporating new usages with acceptable comfort, is in line with the principle of sustainability.

“…However, excluding the overflow of natural light will increase heating demand [38,45]. In the tropics, the positive correlation between visual and thermal performance [37] ensures that dynamic solar shading has an affirmative impact throughout the year [36]. Therefore, space activity and climate characteristics should be considered along with energy concerns to find an optimum design solution.…”

“…The fourth parameter is sky models identified by cloud cover and the frequency of cloud formation, which affects the availability of direct sunlight [30]. Hence, understanding these para-meters could control light and heat loads in buildings [36], which lead shading devices to achieve high performance [37,38] and help provide productive conditions [7,12].

“…Different forms of daylight-linked systems can be utilised with dynamic shading to maximise daylight availability. Al-Obaidi et al [36] utilised a fibre optic daylight system (FODS), which uses fibre optic cables to deliver natural light into a space, along with roof light and dynamic shading in one integrated platform. Therefore, dynamic shading control can be applied as an individual system using single-protocol scheme or linked with other systems in the space, such as DCS or FODS, through a multiprotocol scheme working within independent or integrated platforms capable of sharing other data, such as occupancy, scheduling and HVAC [46].…”

The advancements in software and hardware technologies provide opportunities for solar shading systems to function dynamically within their context. This development has helped dynamic shading systems respond to variable environmental parameters such as sun angles and solar insolation. However, the technical understanding of system design, mechanism and controlling methods presents a challenge for architects and designers. Therefore, this study aims to review the current applications and trends of dynamic shading systems to clarify the potentials and limitations in enhancing system performance based on integrated design objectives. This study assessed several systems on the basis of a critical review to identify different models, applications and methodologies. This study is divided into two main sections: (i) design elements and platforms that engage with specific methods in creating a dynamic shading system and (ii) evaluation strategies to examine system performance. The systems were investigated based on the multiplicity and integration of the parameters involved through various components, such as architectural, mechanical, operational and automation components. The review analysed various studies on the following two bases: (1) geometric-based analysis, which distinguishes between simple and complex shading models, and (2) performancebased analysis, which assesses the shading systems based on two groups of methodologies, namely, theoretical and experimental. The outcome of the review reflects a clear classification of shading models and a comprehensive analysis of their performance. This study generally provides a systematic framework for architects based on thorough research and investigation. Finally, the study introduced several findings and recommendations to improve the performance of dynamic shading systems.
