Buildings have consumed 36% of the world’s total energy. High-rise Residential Buildings have become a trend in Malaysia. Data from National Property Information Centre Q2 2022 (NAPIC) show that the High-rise residential building is the trend for the incoming supply. The energy consumption by the Residential building in Malaysia is vital as it has contributed to 5% of final energy consumption and 21% of total electricity energy generated in the year 2019. Green Building Certifications such as LEED, BREEAM, Green Star, Green Mark have been adopted in various countries to encourage the implementation of green building. In Malaysia, GBI and GreenRE are commonly used for Green Building certification. In this study, three rounds of Delphi survey are conducted to obtain experts’ opinion on significance level of each parameter. This study attempts to explore the significance level of passive design parameters on the cooling load of High-Rise Residential Buildings in Malaysia by using Delphi survey on. Experienced experts from architectural, green building consultant, and structural field in Malaysia were invited for the survey. From the survey, building orientation ranked the highest and followed by glazing (SHGC) ventilation and window to wall ratio. The findings from this study can act as a supporting tool for energy efficient (EE) criteria of GBI and GreenRe and help designers to prioritize more significant parameters during early dedsign stage.
