Abstract

Urbanization and population density surges globally have triggered environmental challenges, with the construction sector notably contributing to greenhouse gas emissions and high energy consumption. Urban expansion has exacerbated issues, converting green spaces into impermeable structures and heightening flood risks. Green roofs have emerged as an eco-friendly solution, excelling in stormwater management, mitigating the urban heat island effect, enhancing air quality, reducing noise transmission, preserving biodiversity, extending roof lifespan, and augmenting aesthetics. They absorb rainwater, decreasing stormwater runoff, yet entail higher installation and maintenance costs and potential fire hazards compared to conventional roofs. In Malaysia, government policies and incentives drive green roof adoption, particularly in residential, commercial, and institutional buildings, predominantly of the intensive green roof type. Buildings undergo green rating tool evaluations for green certification. Despite progress, challenges persist, including expertise shortages, lack of design guidelines, limited research, low public awareness, and green roof component disposal issues. Addressing these demands significant government efforts, including robust policy development, increased support for local companies, expanded research initiatives, heightened public awareness, and optimized synergy with other technologies. Integrating green roofs with solar panels and utilizing greywater for irrigation can reduce energy and water consumption concurrently, showcasing potential for comprehensive and sustainable urban development.

Abstract

The construction industry in Southeast Asian countries especially Association of Southeast Asian Nations receive substantial attention and investment for the high return value of the industry. This review aims to assess the environmental impact of the construction industry in ASEAN countries, analyzing current status, government policies, and innovative green materials and technologies to mitigate environmental effects and promote sustainability. It is important to note that construction industry is currently identified as one of the greatest waste production businesses which can cause adverse impacts and pollution to the environment that degrade the environmental quality. Construction and demolition wastes are emphasized and studied in the following context. The status and government policy on environmental management practices in ASEAN countries such as Malaysia, Vietnam and Singapore are reviewed and summarised in this article. Furthermore, green construction materials and green material technologies that are practised in ASEAN countries are examined throughout the study. The green materials include bamboo, recycled concrete aggregate, coconut husk and bagasse while the green material technologies include hydrogen energy, carbon capture and storage, and solar energy are discussed and evaluated with respective advantage and disadvantages.

Abstract

This review examines the environmental management practices (EMPs) employed within Malaysia's construction sector, with a particular focus on sustainable practices and the adoption of green concrete, including fly ash, rice husk ash, and palm oil fuel ash varieties. The study identifies key challenges, such as low awareness, high costs, weak legal enforcement, and the underdevelopment of green materials in the country. To address these issues, the report proposes solutions such as capacity-building programs, government incentives like tax breaks and grants, regular site inspections, and investment in research and development of green materials. The review also assesses the advantages and limitations of different green concrete types used in Malaysia. The aim of this study is to enhance sustainability efforts and reduce the environmental impact of construction activities through greater awareness, stronger regulatory support, and commitment from all stakeholders. Implementing greener concrete and EMPs is expected to not only mitigate environmental concerns but also yield long-term economic benefits for Malaysia.

Abstract

This review provides an overview of Malaysia's environmental management practices, with a focus on construction waste management, to address the country's growing waste generation in the construction sector. The paper highlights key challenges Malaysia faces in implementing effective environmental practices and offers potential solutions to overcome these hurdles. Additionally, it examines the use of green materials, such as recycled concrete aggregate and bamboo, which have demonstrated significant potential in reducing resource consumption and carbon emissions. The challenges of adopting these materials are analyzed, along with a discussion of their advantages and limitations. Ultimately, the review underscores the importance of environmental management and the role of sustainable materials in transforming Malaysia’s construction industry, while calling for stronger regulatory frameworks and industry collaboration to address these challenges. The objective of this review is to provide insights into the current environmental management efforts in Malaysia and to explore the potential of green materials in mitigating environmental impacts.
