Abstract

Green building is superior in carbon savings and cost savings. Green buildings use lower energy and are healthy for occupant during living or working inside as compared to a conventional building. One of the green building criteria is to achieve good indoor environmental quality. The main objective of this study is to conduct a comparative analysis on the retrofit design of sustainable green building office by determining the indoor environment condition in term of temperature, relative humidity and carbon dioxide on Centre for Languages and Human Development (PBPI) building located at the UTeM’s main campus. Thermal comfort and indoor air quality analysis were conducted to evaluate the indoor environment quality of the lecture room. The analysis consists of physical measurement and subjective measurement. Physical parameter data are collected in two sessions which is from 9 am to 12 pm and from 2 pm to 5 pm with a gap of 5 second interval for 5 minutes in each zone. Physical measurements were conducted with occupancy and no occupancy condition while subjective measurement was carried out through the questionnaire. The result shows that the indoor air quality in term of carbon dioxide of the building is more than 1000 ppm during occupancy, hence it is not within the GBI Standard. The total average relative humidity was recorded 58.35% within GBI Standard (55%-70%). The average operating temperature was recorded 22.21°C less than GBI Standard (23°C - 26°C). Based on the findings, the indoor environment quality improvement retrofit design are proposed with a green building element
