During the implementation process, the construction sector significantly affects the environment, leading to environmental pollution and the overconsumption of natural resources. This jeopardizes the sustainability of a healthy living environment, requiring a solid system to control development. A sustainable and environmentally friendly development system is crucial from architectural, construction, and economic perspectives. However, when applying the concept of Green Building to existing buildings, the cost of green retrofits has increased by about 10.77%. A case study was carried out on the existing BRIN (National Research and Innovation Agency) building to provide alternative solutions to reduce these green retrofitting costs, making sustainable construction the primary option in developing the construction sector. One way to address this cost increase is using the Blockchain-Building Information Modeling (BIM) application, an alternative method to determine the most economical cost based on input or a given model. BIM models contain non-geometric information, including materials for building components, quantities, prices, procedures, scales, and sizes. This allows for real-time data exchange and collaborative decision-making between stakeholders, improving visualization and modeling and lowering costs due to better construction outcomes and higher productivity probability. The implementation of Blockchain-BIM is expected to result in green retrofit cost savings of at least 3% on each green level according to the Ministry of Public Works and Housing (PUPR) of the Republic of Indonesia Technical Guidelines No. 01/SE/M/2022, namely Primary, Intermediate, and Main.

The current green concept trend in Indonesia is contributing to the advancement of sustainability across all industries, including the construction materials sector. The concrete business is crucial because it provides the fundamental components for concrete, which is a critical role it performs in the building process. Throughout the production process, ready-mix concrete has a very negative effect on the environment. Planning and constructing a green concept will be 10-20% more expensive than conventional development. Researchers will use the value for money (VfM)-at-risk analysis model technique to cost-effectively apply the concept of the green concrete industry to statistical analysis and case studies. To improve cost performance, this research updates the knowledge on the green concept for concrete industrial objects and searches for factors that affect its application using partial least square (SEM-PLS) analysis and green concept modeling based on the value for monet at risk analysis model. "10 factors that influence the performance of green costs in the concrete industry" were identified by the research, and they include the following: the risk analysis model, the planning stage, internal costs, production, value for money, the bidding stage, the implementation stage, product use, the operation stage, and maintenance. The application of the VfM-at-risk analysis model was able to increase the green cost performance by 8.66% with a return of 9 years and 2 months by gaining benefits as an environmentally friendly and sustainable concrete industry.

The emission and mitigation of greenhouse gases transforms the status of urban environ ments. However, a policy accounting for all the aspects associated with transport is lacking. Prob lems related to transport include a greater reliance on cars, increased congestion, and environmental impacts. The absence of an efficient public transport system is a notable cause of the prompt escala tion of diverse problems, for example, increases in the number of personal automobiles causes con gestion on the road, resulting in air pollution, ubiquitous greenhouse effects and noise pollution, which ultimately affect human health. Over the past two decades, a growing number of communities have pursued light rail transit (LRT) and Transit-Oriented Developments (TODs) as part of an integrated transportation and land use strategy to revitalize and/or regenerate the built environment of worldwide cities. Green TOD focuses on combining TOD with green neighborhood to generate larger ecological and environmental benefits. In their research, Cervero and Sullivan suggested that the combination should be realized in the following aspects: (1) higher densities, (2) mixed land use, (3)reduced. The integration of Blockchain with BIM for data provenance uses a distributed network for storing provenance data over a decentralized and fault-tolerant ledger With the results of this research, there is expected to be shared awareness and concern about implementing green neighborhood and green space as an initiative to present a more energy-efficient transit oriented, save operating costs, and provide comfort to customers.

This paper aims to determine the impact of accelerated duration on profit and contingency costs. The method uses the design and build project of a high-rise office building, which begins with an analysis of the actual project schedule, the possibility of accelerating the duration with the assumption of additional working hours for workers and the impact of perceived duration on project costs. Then proceed with System Dynamic (SD) modeling with reference to the Time Cost Trade Off theory and end with a scenario of the relationship between project activity acceleration, profit addition and crashing costs. Project acceleration can improve project performance by considering the effect on profits and contingency costs, with a Schedule Performance Index (SPI) of up to 37.8%, it can increase profits between 4.08% due to reduced indirect costs.
