An Analysis on Energy Performance of Existing Green Constructed Building Design Certified by GreenRE and Other Rating Certification System in Malaysia
Supported by GreenRE, this study examines the link between electricity consumption and carbon emissions in Malaysian commercial green buildings. The objectives were to calculate the Building Energy Index (BEI) and CO₂ emissions. Results show the most efficient building is a Johor museum (46.50 kWh/m²/year), while the highest consumption is a Kuala Lumpur shopping complex (299.00 kWh/m²/year), both within MS1525:2019 standards. CO₂ emissions correlate strongly with energy use (r = 0.71), peaking at 2,123,027.85 MtCO₂ for the shopping complex and lowest at 744.80 MtCO₂ for the museum. Findings reinforce GreenRE’s commitment to promoting energy efficiency and carbon reduction in sustainable commercial developments.
Evaluating and comparing objective and subjective thermal comfort in a malaysian green office building: A case study
This study explores thermal comfort in a sustainable Malaysian office building, examining the link between objective environmental data and occupants’ subjective experiences. Using the Predicted Mean Vote (PMV) model and occupant surveys, findings show that while indoor conditions met thermal comfort standards, occupants perceived the environment as colder than predicted. The research highlights limitations of conventional models in tropical climates and stresses the need to consider individual variability, localized factors, and adaptive comfort mechanisms. By integrating empirical data with subjective feedback, the study advocates occupant-centered design strategies to enhance well-being, energy efficiency, and carbon reduction in green buildings
