Published: September 2022

Abstract
Ambon City has limitations in the development of residential areas because it is in an area prone to earthquake disasters, This is because Ambon City is in a very active tectonic area and 65% of settlement land / land built in Ambon City is in an active and weak fault zone and if there is a plate movement there will be an earthquake along the weak zone. One of the first steps to the effort to stigmatize disasters is to estimate how large the area of settlements that have been analyzed using cellular automata markov-chain located in earthquake-prone areas. This study aims to analyze changes in Ambon city land cover in 2012, 2017, 2021 and predict land cover in 2031 and synthesize spatial dynamics of settlement land availability with earthquake-prone areas in Ambon City in 2021 and 2031. This study uses Cellular Automata modeling to predict ambon city land cover in 2031 which will be covered with a map of earthquake-prone areas obtained from BPBD Ambon City to see residential areas that are in earthquake prone areas in Ambon City in 2021 and 2031. The results showed that the area of built land affected in earthquake-prone areas has a straight proportional relationship with the year of land development built. So that the more years then the area of land is built in areas prone to earthquakes and increasing. This research is expected to be used as a reference in the management of sustainable settlement area development and for efforts to organize space based on disaster mitigation in order to minimize losses and casualties due to earthquake disasters that will occur in Ambon City in this future.

Abstract
Bamboo has been widely used for water resource conservation. The benefits of bamboo as a water resource conservation plant are not well known by the public. This paper discussed the process of promoting bamboo as a conservation plant for the people of Jedong, Wagir Subdistrict, Malang Regency. They used water from Sumber-Wangkal and Sumber-Cokro Springs to fullfil their water needs. The methods applied in this research are soil surveying and causal loop diagrams model. The soil surveying and causal loop diagrams model were done to get the spring’s soil conditions and to find out the water resources conservations efforts by Jedong people in both springs, respectively. The soil samples analysis showed that the soil in both areas is suitable for bamboo plants. The causal loop diagrams (Jedong Water Resources Conservation) model showed that the village-owned water management (Pengelola Air Minum Desa/PAMDes), as the organizational system on water reseources management will be able to promote the bamboo plants for conservation. Promoting bamboo plants to the Jedong community is very important to support the water resources sustainability in Jedong.

Abstract
The high backlog of houses in Yogyakarta City illustrates the high demand for housing. Limited land stock causes the appearance of slums and vertically directed housing, for example, the construction of Rusunawa Jogoyudan. This study aims to analyze the assessment of housing quality, perceptions, and the population’s preferences. This quantitative study uses data sources obtained from literature, questionnaire, and observation, then analyzed with diagrams and cross-tabulations descriptively. This study finds that there is a compatibility between the population’s perception and the housing quality assessment. Between owning and needing a house, some populations answered owning a house for housing priority and plans. The choice of housing in the future was dominated by those who plan to live in non-flat housing rather than Rusunawa Jogoyudan. There is no correlation between the preferences in housing options with the income, housing quality, housing ownership status, also perception about Rusunawa Jogoyudan. Convenience is the population’s motivation not to choose Rusunawa Jogoyudan. The comfort in question is a better environment, calmer atmosphere, no rental thoughts, already own a house, easier to interact with, more flexible, wider space, no need to go up and down with stairs, and more privacy than living. at Rusunawa Jogoyudan.

Abstract
Environmental Quality Index (EQI) has been used as a common measurement for environmental quality in Indonesia. However, EQI is only measured in a wide administrative area. In reality, environmental quality measurement in smaller areas is also needed to formulate the right environmental policy. EQI study at Universitas Gadjah Mada (UGM), as an urban campus, is important because it prioritizes the educopolis vision which commits to create a conducive education environment and be responsive to ecological issues. This research aims to identify the EQI of UGM and analyse the vision of educopolis and open system campus related to EQI. The method which is used is mixed-method of quantitative to obtain the EQI value from Air Pollution Index, Water Pollution Index, and Forest Cover Index, as well as qualitative method to review the educopolis vision and open system campus through analysis of strength, weakness, opportunity, threat (SWOT). The EQI in this study is 50.77, categorized as very less. The vision of the educopolis campus in contrast with the current open system campus. The management strategy to improve the EQI is formulated through the management of vehicles, waste, integrated water in Belik and Code sub-watersheds, and urban green space.

Abstract
Construction consumes about 40% of resources globally. The switch to a circular economy model in the building industry can contribute to the reduction of use of resources, and lower the environmental impact by extending the life cycle of building components and materials. However, circular economy principles in building industry are not yet established, while at the same time the complexity and consequences of such a transition require further research. The objective of the exploratory study “City Remixed”, whose first results are discussed in this paper, is to identify re-use and recycling potentials of Graz’s building stock for the city of Graz, in order to initiate the transformation of the building sector of the city towards the circular economy. Considering the city of Graz and its surroundings in a reasonably short transport distance as a closed system, we started by quantifying the existing building stock in form of a digital 3D model as shown in this paper. In addition to the recording of the materials or construction elements present in buildings and infrastructure (networks) and quasi bound in them with regard to type of building material, quantity, condition and position in a geo-information system (“urban cadastre”), the expected future time of availability of the material or construction element is also to be recorded digitally. In the future we will enrich the model with metadata, in order to enable the investigation of re-use and recycling potential of the components and materials as well as to determine companies, manufacturers testing and certification institutes that are necessary for these processes. Finally, we will develop renewal scenarios based on the existing building stock, as a result of possible component and material flows. From this process, we identify the fields of action, we settle decision-making bases and provide recommendations with regard to the transformation to a circular economy for different stakeholders, including the citizens. In this context digital technologies allow the storage, retrieve, management and update of large amounts of information, support the development of circular economy scenarios, which in turn offer a simple way towards the re-use and recycle of materials in the building industry.
Rethinking recurring waste flows: Creating material cycles by identifying new use cases for idle materials
Authors: Scholz Johannes , Ordóñez Isabel , Rotter Susanne 
Published: September 2022

AbstractThis article presents Collaborative Material Workshops (CMW), aimed at identifying new use cases for commercial waste materials waste materials, which are continuously being generated and have valuable technical properties. With the assumption that such materials habe a high re-use potential, they are defined here as idle material streams. The objective of CMW is to identify scalable and feasible applications for the re-use of idle material streams and to communicate those results to commercial adopters. In cooperation with a local secondary material initiative and a project-related NGO, TU Berlin researchers have investigated the idle materials “printing blankets” and “aluminium composite panels” in two CMWs. Both materials combine valuable technical properties, a short use phase, and poor recyclability. The resulting two CMWs included 1) detailed background research, 2) physical material testing and 3) experimental CMW with material-related experts. With a special focus on the construction industry, the erticle discusses the barriers of identifying scalable and feasible new use cases for idle materials through the method of CMW.
How is the construction sector addressing the Circular Economy? Lessons from current practices and perceptions in Argentina
Authors: Cohen J , Rosado L , Gil J 
Published: September 2022

Abstract
The Construction and demolition (C&D) sector mobilise a significant number of resources and at the same time is responsible for a large fraction of waste worldwide (40%-60%). Although, the environmental impact of these by-products is low, waste generated finishes in landfills, is downgraded and because of its volume it has become a priority at different governmental levels. In this context, the Circular Economy (CE) provides a set of strategies to improve efficient use of resources, thus reducing the environmental footprint of C&D. Most academic literature has focused on China, Europe, or the US, but knowledge about CE practices and perceptions in global south countries is scarce. To reduce this knowledge gap, this study focuses on Argentina and explores what are the perceptions, challenges, and opportunities for adopting CE strategies by the C&D sector. To achieve this goal, a survey was developed and distributed with support from the Argentinean Chamber of Construction (CAMARCO), among members of the chamber and other C&D relevant networks. The survey was carried out in the Autumn of 2021 and 88 C&D firms representing different size, longevity and business cycle responded. The results of the survey show that most of surveyed firms are trying to engage with the concept of CE. Secondly, a lack of digitalisation and information are seen as important barriers to transition to CE. Finally, policy makers should focus on providing financial and tax incentives to secure a better environmental future.
The socio-spatial effects of Circular Urban Systems
Authors: Hubmann G 
Published: September 2022

Abstract
This article shows what kind of urban spaces are produced by circular systems. The focus is on the socio-spatial dimension of closed material loops in two neighbourhoods (e.g., reuse of grey water, recycling of waste, provision of renewable energy). Although the Circular Economy (CE) narrative is increasingly part of urban transformation policies, there are considerable implementation gaps in how regenerative or self-sufficient systems are operationalised in practice. I argue that the application of circularity principles in the urban context requires conceptual clarification to be useful for urban theory and praxis. Therefore, I provide a political ecology perspective of circular urban systems by analysing two cases: Block 6 in Berlin and Schoonschip in Amsterdam. I explain how such systems were established, who benefits from them, and what kind of socio-spatial conditions they produce. Methodologically, I use several qualitative research methods in the framework of a case study analysis. The results show that the incremental and publicly financed low-tech development of circular systems is socially compatible while privately funded high-tech developments result in stronger levels of sustainability but are reserved to a small exclusive group of people and provoke gentrification processes.
Environmental and economic analysis of new construction techniques reusing existing concrete elements: two case studies
Authors: Küpfer C , Bastien-Masse M , Devènes J , Fivet C 
Published: September 2022

AbstractAs the most widely used construction material worldwide, concrete is the main cause of greenhouse gas emissions, material depletion, and waste generation by the construction industry. Typically, concrete waste is crushed and, at best, reclaimed into recycled aggregate or used as gravel. This process is energy-intensive and results in a reduction in material properties. In contrast, the direct reuse of concrete elements from obsolete structures offers great potential for significantly reducing the environmental impact of new constructions. To be reused, concrete elements are carefully sawn out of soon-to-be-demolished buildings. Elements are then used without other major transformations for another service cycle in a new assembly. This paper analyses two recent projects in Switzerland that showcase innovative applications of concrete reuse: a post-tensioned segmented arch footbridge and a parking pavement. Both projects reuse blocks extracted from cast-in-place concrete buildings undergoing transformation or demolition. In this paper, environmental and economic analyses provide a comprehensive understanding of the alleviations and costs involved. Results are compared to those of alternatives with conventional construction methods. The two projects reusing concrete globally showcase a drastically lower environmental impacts for comparable or higher construction costs, hence calling for future developments of such new circular construction strategies.
Reno-DM: A Knowledge model to support the decision-making process in the context of residential building renovation projects

Published: September 2022

Abstract
The decision-making process to select solutions in residential building renovation projects is a complex task. These projects encounter rigid governance and ownership structures, participation of multiple stakeholders, diverse requirements, and a lack of consensus regarding methodologies and tools used within the decision-making process. Addressing some of these challenges requires a shared understanding of this domain. Therefore, this paper presents the Renovation-Decision-making (Reno-DM) model mapping key knowledge from the decision-making in renovation projects. It considers project characteristics, context information, building features, and their relation to aspects of the decision-making itself. The development of the Reno-DM model relies on an existing decision-making representation and the extraction of new concepts from interviews with stakeholders taking part in renovation projects and related literature. The interviews are analysed following an inductive content analysis approach. The Reno-DM model is developed in the form of an ontology. It provides a basis from which future knowledge management and reuse applications can be developed and deployed to support improvements in the decision-making process in the renovation field.
