In recent years, green building has been a trend in the world. Green building in Malaysia is still lagging in terms of development in green building. The construction industry has contributed the greatest percentage of greenhouse gas emissions. In order to reduce this issue, the increase in implementing green buildings is a concern among different construction stakeholders. The aim of this study is to investigate the barriers to implementing green buildings in Malaysia. A systematic review was used to achieve the research aim. A PRISMA protocol was used to present the systematic review. The systematic literature review was conducted between 2018 and 2022, and a total of 18 articles were analyzed. In the process, Scopus and Google Scholar databases were used to find the pertinent articles. In this study, the barrier the green building implementation in Malaysia were identified and categorized into several barriers related to economic, technology and training, knowledge, financial and political aspects. The highlighted key barriers contributed to both industry and government increasing the implementation of green building in Malaysia.

The purpose of this study is to explore the factors and benefits that can encourage the building management team to adopt the solar energy usage in Malaysia. Solar energy has been long introduced to the industry as a practical renewable technology, but the adoption rate is still low in Malaysia due to the dependence on oil and fossil fuels. Thus, costs and benefits of solar energy application and the best solar panels to be used in Malaysia have been explored for practitioners’ reference to improve the adoption rate. Mixed method was adopted in this study. First, quantitative method was adopted where 200 sets of online questionnaire survey were distributed to the public to collect the information about the solar energy application. Next, a semi-structured interview was carried out to further investigate the reliability of collected data. Based on the findings of the questionnaires, the most significant benefits of solar energy are renewable and clean source of energy, eco-friendly, and cost saving. The results indicated that Mono-crystalline silicon cell is the most popular type of solar panel that widely used in Malaysia. However, the adoption of solar energy is low due to the high initial cost and insufficient knowledge and awareness among citizens. Through the results of this study, the adoption of solar energy can be doubled in future as the results reveal the factors and benefits that could help the policy makers to utilize the implementation of solar energy in residential buildings that massively consuming the energy in daily basis.

Timeliness, budget consciousness, and quality are critical to the success of a project, and become increasingly challenging with increased project complexity. Five-dimensional building information modeling (BIM) integrates cost and schedule data with a 3D model, and enhances project management by addressing budgeting, timelines, and visualization simultaneously. However, a comprehensive assessment of 5D BIM’s impact on key performance indicators is currently lacking. This research aims to identify the critical factors influencing the adoption of 5D BIM and its impact on key project performance indicators. A thorough systematic literature review and qualitative analysis were conducted to achieve this goal. Relevant articles from the past decade (2014–2023) were examined from the Scopus and Web of Science databases, of which 222 were selected and screened using PRISMA procedures. This research found consistent and rapid updating of keywords, highlighting the dynamic evolution of 5D BIM and its expanding applications in the construction industry. Thirty critical factors affecting the adoption of 5D BIM were identified and categorized into the following six groups based on the technology–organization–environment (TOE) framework: technology, organization, environment, operator, project, and government policy. The 15 factors driving construction project performance in integrated 5D BIM were divided into cost, time, and quality performance based on key performance indicators. This review offers innovative insights into 5D BIM adoption, and can aid stakeholders in developing effective 5D BIM implementations.

This study aims to investigate the impacts of green site management on corporate environmental and economic performances by improving the efficiency of energy and water consumption at construction sites. The identified green site management has been proven to improve both environmental and economic performances. This study allows practitioners to study and advocate for appropriate green site management strategies. A qualitative method was carried out since this research focused on the construction players’ opinions on green site management practices. Five contractors were selected randomly from the construction sites in Malaysia based on the convenience sampling method. All selected respondents were qualified to give opinions as they held management posts. The results have shown green site management practices can reduce the consumption of resources and improve energy efficiency management and water consumption management, which are considered to have a positive impact on the construction project’s environmental and economic performance. The findings also revealed that green site management practices implementation must not affect their economic performance, such as increasing the construction cost with high initial and maintenance costs. As the construction industry consumes a vast amount of water and energy daily, these consumption reductions can help construction sites achieve energy efficiency and utilize natural resources, eventually improving corporate environmental and economic performance. Thus, green practices must be implemented to bring sustainable development to the construction industry.

Cost management is one of the most essential tasks in engineering construction. It is a crucial factor in the success of the project. The fifth dimension (5D) of building information modeling (BIM) has a different impact on cost management in the construction industry. Whereas, stakeholders are not eager to adopt procedures that are unrelated to their business. Therefore, this study determines the link between 5D BIM practices and cost management in the China construction industry to guarantee that the most suitable practice in 5D BIM is adopted. A systematic review method was adopted to assess the 5D BIM approaches to conduct the relationship between 5D BIM practices and cost management. The research involves references to the science journal databases Emerald Insight, Science Direct, and Google Scholar to find the pertinent journal publications in the data collection phases. The findings of the research indicate that the implementation of 5D BIM is agreed as beneficial, and a thorough conceptual framework is developed from this research to demonstrate the connections between 5D BIM practices and cost management in China construction sector. Cost management is optimized in various ways for 5D BIM implementation. To accomplish effective cost management and maintain their competitiveness in the market, construction industry need to comprehend the 5D BIM relevant solution and relationships. A throughout conceptual framework that demonstrates the connections between 5D BIM and its impact on the cost managment of construction industry is established through a thorough literature review, enabling stakeholders to comprehend potential benefits in cost management. The research provides new awareness and information about the 5D BIM technologies that are available concerning the demands for cost management. It address the value-added of the construction industry output and improve the industrial competitiveness of enterprises.
