Rapid urbanization is changing the urban landscape, especially in tourist areas such as Jalan Raya Legian, Bali. Infrastructure growth in these areas significantly impacts the built environment, where building facade materials play an important role. Facades not only act as aesthetic elements but also influence the environmental impact of buildings. Conventional materials such as concrete, glass, and aluminum have a large ecological footprint due to their energy-intensive production process and exploitation of natural resources. This research identifies and analyzes using facade materials on Jalan Raya Legian to realize sustainable development. Qualitative research methods reveal the dominant types of facade materials used, their characteristics, performance, and impact on the environment. Jalan Raya Legian is dominated by commercial buildings with modern (glass, aluminum composite panel, concrete, steel) and traditional (brick, wood, natural stone) materials, as well as the trend of using environmentally friendly materials such as secondary skin. Negative impacts of facade materials include the greenhouse effect, light pollution, material waste, and use of natural resources. Positive impacts include using traditional materials and applying secondary skins to reduce room temperature and improve air quality. Solutions to reduce negative impacts include the selection of environmentally friendly materials, climate-responsive design, minimization of material waste, use of secondary skin, and government regulations and incentives. This study concludes that the selection of facade materials on Jalan Raya Legian has a significant impact on the environment. Joint efforts from building owners, architects, and the government are needed to minimize negative impacts and realize a sustainable built environment. Each material has advantages and disadvantages regarding environmental impacts, so wise selection and a sustainable development approach are essential to minimize negative impacts on Jalan Raya Legian.
