Abstract

Indoor thermal comfort and operational cost has remained a critical concern for every building design in Malaysia. In fact, passive design measures are important factors in building design for energy efficiency and environmental performance. To support the development of passive design, a study of the elements of passive design, as well as its benefits and challenges, is required to improve public awareness of green building. In this research, a few industry professionals were invited to participate in an interview to give their ideas and knowledge on the issue of passive design in Malaysia. Then, the qualitative data is coded and further discussed using content analysis. Finally, the study successfully verified which passive design strategies are suitable for Malaysian climates, as well as the benefits and challenges. The building orientation, shading, thermal insulation, and daylighting are all passive design elements can be employed in Malaysia. However, natural ventilation passive design is ineffective due to the local weather and the high cost of light thermal materials are not suggested for use in Malaysian passive designs. In addition, passive design may offer reduced operating energy costs, increased occupant comfort, and long-term growth. On the other hand, the passive design has no relation on the building's construction quality and productivity. Finally, the study identifies a number of possible challenges to the growth of passive design, including a lack of public awareness and knowledge, greater upfront costs, and ineffective government regulations. After all, the present condition of passive design in Malaysia will be better understood by readers, and industry experts will be better equipped to address particular challenges in the development of passive designs. To overcome environmental challenges and build a better, "greener" future, the development of passive design is important.
