Thermal comfort is a part of indoor environmental quality that should be considered to ensure the occupants' well-being. Unconducive buildings not only bring occupants discomfort but also tend to affect health, disrupt the process of teaching and learning, and reduce work productivity. Thus, this study determines the thermal condition of existing workshop buildings used in Technical and Vocational Education and Training (TVET) implementation. ASHRAE Standard 55 (2017) is referred to in the determination of thermal comfort involving objective measurements and subjective measurements. Observation methods of environmental variables such as air temperature, radiant temperature, air velocity, relative humidity is observed. Evaluations of comfort are based on occupant surveys and environmental measurements. A total of 257 people completed a questionnaire distributed at three technical institutions in Kedah, Malaysia. According to the findings, the average thermal sensation vote is 1.85, which leads to 66.5% of respondents feeling discomfort. Meanwhile, the adaptive model analysis showed that the workshop environmental conditions were out of the comfort zone and did not comply with the ASHRAE 55 standard. Hence, the thermal discomfort factors from the occupants' perspective were identified and widely discussed. As a result, the research findings will benefit parties involved in new building construction or existing building renovations to improve indoor air quality.

Hybrid System in Industrialised Building System (IBS) is combining IBS components with conventional method. Delay has become a familiar issue in construction field. The issues pertaining structure stability when using this combination method leads to delay while installing these two different method components. The combination also could cause a defect jointing. In Industrialised Building System (IBS), even though it is one of the technology methods that can save times, cost, and reduce labour in construction, but there still have constraints such as design issues, lack of experienced worker, and internal and external issues that can affect cost problems. In this study, the suitability structure based on combination method is investigated to discover the affected factors of suitability structure by using Hybrid System which is the aim of this study. The data analysis from quantitative survey shows that the top three affecting the building structure are: 1) weather effects with highest mean of 6.25 followed by 2) delay of jointing process at 6.03 and 3) defects from monolithic jointing at 5.93. Therefore, the amount of average data obtained shows that the most affected structure is the Hybrid System.
