    Low-carbon (LC) materials and alternative technology must overcome various institutional policy and market constraints to gain greater acceptance in the construction sector. The primary impediments that must be addressed to build a viable and sustainable local construction sector are awareness and knowledge. To analyse the perspective on LC materials in the northern states of Malaysia, 93 companies were surveyed via their construction building professionals (CBPs) on awareness, usage frequency, user experience, drivers for material selection and barriers to LC material adoption in projects. To establish an understanding of CBPs and LC materials, survey data were analysed using semi-structured qualitative-quantitative approaches and the Statistical Package for the Social Sciences (SPSS), influenced by basic theory. 79.57% valid responses indicate that most participants had a low degree of awareness, with 95% confidence that there is no difference in the score levels of the overall viewpoints between architects, civil engineers and structural engineers. While unfired bricks (16.2%) are commonly and widely employed in construction projects, structural insulated panels (40.9%) are the most favourable LC materials for future projects. Client requirements, regulatory requirements and expectations of a shorter completion time are the most important factors driving CBPs to select LC materials, accounting for 44.6%, 37.8% and 37.8%, respectively. According to the CBPs, the main constraint factor to market acceptability is the “Lack of sustainable material information” (44.9%). The proposed recommendations include “Training on designing a building with LC material”, “Clear regulation on limiting carbon emission in a project” and “Increase demonstration of projects and case studies” at a rate ranging from 36.5% to 43.2% to improve client and CBPs acceptance of LC materials for a more sustainable building sector.

    The Contractors' Perception on the Development of Green Building Projects in Penang
    A strategy to lessen the substantial effects of the building development on the environment, society, and economy is green construction. However, despite the positive effects of green buildings on society, numerous market hurdles prevent the growth of green buildings, particularly in Malaysia. This happens because of the lack of awareness regarding the development of green buildings. Therefore, this study aims to explore the contractor perception of the development of green building projects in Penang. A set of questionnaire survey was distributed among eighty-three (83) contractors representing construction organizations in Penang. The analysis showed that the contractors mostly agreed with the benefits of green building, indicating that the respondents are aware of green building. The results shows that financial factor with mean value of 4.66 is the main factor hampering the development of green buildings, followed by law and regulation factor (x ., = 4.60) and quality factor (x ., = 4.54). Besides, most of the respondents also agreed that improving the professional knowledge among contractors (x ., = 4.70) will encourage the development of green buildings. Immediate action should be taken on the strategy either from their sides or from other authorities. Overall, this research provides insight into the perception of the development of green building projects among contractors, which can increase awareness on green building and contributing to a better environment.
