Study on sustainable rental housing with sublease partnership utilizing existing owner-occupied vacant houses
Authors: Watanabe S , Sumikura H , Nagano M 
Published: November 2020

Abstract
Despite the increase in vacant houses in Japan, existing owner-occupied vacant houses are not sufficiently converted into rental housing due to homeowners’ anxieties in legal and economic matters. In this study, we explore cases of the housing projects introducing sublease partnerships of owner-occupied houses; the projects by the municipality as a PPP collaboration and the projects introducing a lump-sum payment of a rent as a purely private business. These projects are found to have succeeded in dispersing among parties the costs and the risks a homeowner would take by achieving the three conditions; (1) A deal including renovation work, (2) Fixed-term lease contract and (3) More credible contracting party. The sublease partnership has the potential to convert owner-occupied houses into rental housing. However, some challenges which limit the sustainability of the partnership are pointed out.

Authors: Sumikura H , Hyodo S , Ishigaki A 
Published: November 2020

Abstract
In Japan, the number of migrants from urban to depopulated rural areas is increasing. The migrants’ participation in the local community encourages them to settle down and promotes revitalizing the area and utilizing vacant houses. This study aims to clarify housing acquisitions by the migrants to the depopulated area and the interaction with the locals after migration in Osaki-Kamijima town located in the Seto Inland Sea. Based on data gathered from questionnaires and interviews with migrants, the authors led that the migrants thought much about communications with the locals during the migration process and acquired housing through direct negotiations with homeowners. Also, we mainly indicated that there is a tendency to blend into the community while participating in local management activities.
Towards sustainable transitions of peri-urban neighborhoods of detached houses
Authors: Drouilles J , Rey E 
Published: November 2020

Abstract
Peri-urban neighborhoods of detached houses are facing countless challenges related to the building stock’s low energy efficiency, to the current demographic transition reducing household size and increasing the proportion of elderlies, to their distant location combined with exclusive residential use and few public transportation services. Those challenges represent growing issues for the upcoming years, with regard to the role those neighborhoods have to play in contributing to the collective challenge of the energy transition and to the fact they would have to cope with eventual future crisis. Hence the research investigates the transition potential of existing peri-urban neighborhoods of detaches houses by 2050, in Switzerland. Through a more focused approach, the paper, complemented with a poster, aims at highlighting how future evolutions might affect the overall sustainability of those residential areas. To do so, it focuses on the multicriteria assessment of five scenarios envisioned for peri-urban neighborhoods of detached houses and applied in six Swiss case-studies by 2050. The scenarios Caducity and Exclusivity follow business as usual trends. The scenario Opportunity investigates the effects of soft-densification processes, and Urbanity and Mutuality offer new perspectives towards densification or landscape integration. A multicriteria comparison relies on results of the systematic assessment of the neighborhoods’ environmental quality, energy efficiency, economic viability and social diversity in 2050 and of the scenario’s feasibility. It innovates by relying on a spatiotemporal assessment methodology developed at neighborhood scale. Altogether it provides a qualitative decision-making support by identifying strengths and weaknesses of each scenarios. The overall average results show that Urbanity, which concentrates its actions on a few plots, presents the best-balanced performances among all criteria. All the other scenarios are favorable to one or two criteria only. Besides providing decision-making support, this assessment also sets a framework to reorient public policies towards more resilient peri-urban residential neighborhoods.
Function-based system modelling to structure sustainability of buildings
Authors: Fauth R 
Published: November 2020

Abstract
A reduction of harmful environmental impacts regarding sustainable building design is challenging the real estate industry. Achieving this reduction, it is necessary to assess sustainable building design. Such assessments are mainly structured as a system of independent criteria and disciplines. These common procedures consume essentially time and resources. All buildings can be described as a system with different interactions to the environment. Relevant interactions for a sustainable environment can be systematically identified and modelled as sustainability functions. This approach aims to develop a function-based system by structuring criteria for an optimized assessment. Derived functions, like heat insulation and sun protection, indicate technical causes for the environmental impact for a better comprehensibility. The outcome of this paper supports further developments to assess the quality of sustainable design in the real estate environment.

Published: November 2020

Abstract
The transition towards sustainable cities requires extensive improvement of environmental and energy consumption performances. However, the design of alternative sustainable scenarios is a complex issue which involves a large number of indicators and multiple stakeholders. In this regard, the use of appropriate assessment tools and decision-making models for addressing this issue are needed. This study aims at presenting research activities with a specific focus on the definition of policies and decision-making models to guide future transformations in the city, developing a “sustainable path”. The result is a new multi-criteria indicators-based system for supporting decision making at the city level. This includes the organization of a workshop in order to select the relevant indicators and to assign the stakeholders’ preferences using a multi-criteria method. This approach is used in order to investigate the stakeholders’ perspectives on the impact of each indicator on the different future sustainable scenarios. Eight indicators have been selected, and accordingly, assessed through the collection of data for the “baseline” scenario. Next step will involve the definition of different forward-looking sustainable scenarios and the assessment of their impacts through the selected indicators. Finally, all the scenarios will be verified through a second interactive workshop as part of the sustainable urban planning process to choose the best scenario.
Roof windows – solutions and limitations
Authors: Tywoniak J , Stanek K , Calta V 
Published: November 2020

Abstract
Paper deals with the roof windows (skylights) from building physics point of view. Based on several introductory analyses an innovative solution of the frame and sash construction was developed in close cooperation with the industrial partner. Resulting parameters correspond to requirements set for passive house level windows (minimized heat transfer, avoided risk of water vapor condensation). The frame and sash consist of effective combination of soft wood and hardened plastics. Glazing unit can be traditional, triple glazed, or double glazed with additional two transparent foils dividing the space into 3 cavities. The analyses also showed that the effect of sloping, and the effect of thermal coupling between window and roof, play a significant role in the overall performance. Thermal transmittance of the roof window, U
w, in the best category developed here, is 0.50 W/(m2K). When both the effects are included, its real thermal transmittance, U
real, is increased to 0.82 W/(m2K). Further development ideas and impulses for theoretical studies are mentioned in the final part of the paper.

Published: November 2020

AbstractThe inevitable expansion of the built environment due to the rapid growth of the urban population in emerging contexts poses a great challenge for the sustainable development of local communities. This problem could be faced by providing adequate multistorey building solutions while using sustainable and eco-friendly materials, preferably from renewable or upcycled and locally available sources. These materials tend to have lower mechanical properties than those commonly used in conventional structures and therefore not adequate for elements subjected to bending such as floor slabs. This challenge can be met by improving the strength of the locally available materials and/or using geometries specifically designed to lower the structural stresses such as funicular structures. In this study, a novel clay-based cementless material is used. Different mixtures and additives were tested to achieve similar processing advantages as concrete. A parabolic arched floor element is designed based on a parametric analysis using graphic statics to reduce structural stresses and weight. The fabrication system is based on reusable formworks in which locally available earth is used as part of the mould. A four meters span arched floor is built to analyse its structural behaviour and to evaluate the proposed fabrication method.

Published: November 2020

Abstract
A practical way to reduce energy consumption is to use traditional construction methods and materials. Persian architecture has a long history of constructing energy-efficient and comfortable buildings for the human and has created sustainable cities. Hygrothermal analysis of a building in Yazd, a city in the hot-dry region of Iran, was performed, and the possibility of use of adobe in modern construction for energy-efficient buildings was examined. The aim was to determine the indoor temperature and relative humidity and study its effect using or not using cooling and heating systems. For the simulation, the WUFI + code was used, where internal temperature and relative humidity were determined. Results showed that the use of traditional materials had a considerable effect on reducing internal temperature and humidity fluctuations.

Abstract
To solve challenges in management of sewage infrastructure in cities with the same features of Piumhi, Brazil, this research seeks to study a method of work for the management sewage system that aims, based on accurate information, to act in a preventive way and increase the quality of the decision making as the city growths and new projects areas are occupied and to prioritize investments. Strategies for the field survey for the diagnosis of the collectors and interceptors and for wells’ information collect were stablished through meetings with the local autarchy SAAE (Water and Sewage Public Provider). A computational tool, based on Python codes, was developed to facilitate the input of georeferenced data into the QGis software. Tutorials of preventive management and contracting and supervision of future projects to the sewage network were also developed. The information obtained from the survey of the wells showed several barriers arising from the corrective management model adopted previously by SAAE and from ignorance of the population about the operation of the sewage network. During the network mapping, several stretches missing were found, some of them were corrected based on the analysis of the topography and of the wells upstream and downstream. The tool developed allows that any server of the autarchy gets access to the information about the operation of the system. Besides it allows the identification of problems and compares them to the conditions and features of the existing network, enables the definition of strategies of preventive actions and improvement of infrastructure from a historical assessment. The registration of the sewage network allowed match GIS tools and the BIM concepts, innovating the management process, improving the attendance to the population, increasing the quality of life and seeking a sustainable model that might be used by other public managers, walking towards the concept City Information Modeling.

Abstract
As the rates of urbanization increase to unprecedented levels, the urgent need for sustainable housing and infrastructure has become a widespread global challenge with social, economic and ecological implications. The housing sector directly impacts the majority of the United Nations (UN) Sustainable Development Goals (SGDs). However, striving to achieve these goals in a compartmentalized or siloed manner has impeded the implementation of transformational solutions that increase the security and wellbeing of urban populations. Here, we introduce the Built Environment Ecosystems (BEE) framework, alongside a case study from the Ecological Living Module (ELM) UNEP Program, through an integrated systems approach with synergistic impact. We demonstrate how the multifunctional interlinking of building systems that harness local bioclimatic resources (ie. solar, wind, water, food, agricultural waste, biomaterials) can more viably address a broad spectrum of sustainable development challenges, while increasing local stakeholder agency. We outline how the BEE framework enables the association of SDGs as an integrated package, with an ELM performing as a scalable but Self-reliant Ecosystem of Systems, that could enable systemic change, suggesting the need for further research towards a scale up in the density of such housing systems across multiple climatic and cultural contexts towards ubiquitous sustainable urban housing.
Digital urbanization of remote rural cities through design as a catalyst for sustainable development: The case study of Puerto Williams, Chile
Authors: Vivanco T , Yuan P 
Published: November 2020

Abstract
This article presents the firsts phases of interlocking between community, city and digital manufacturing infrastructures, focused on the case study of Puerto Williams, Chile, the southernmost city of the world. Its process of digital urbanization for sustainable development based on technological education for the local school and community, by combining digital fabrication for the design and production of local solutions. Located in Navarino Island, Puerto Williams has no high-speed internet connection, and it does not produce any energy and goods, being utterly dependent on ships that bring liquid gas, products and raw materials. In January of 2019, a fully-equipped Digital Fabrication Laboratory opened, and fibber optic internet expected to arrive by the end of 2020. These conditions establish the basis of digital urbanization process for rural, pre-digital and isolated communities.
Co-Evolution of Business Strategies in material and construction industries and public policies

Published: November 2020

Abstract
Traditionally, gravel, cement and concrete producers focus on their role as material or resource suppliers. The higher the material turnover, the higher the economic success. Hence, the business-model is in conflict with the societal goal of increased resource efficiency. Driven by stricter regulations, some companies have recently developed new business models focusing on additional services in waste-management and logistics. From a policy perspective, such diversification strategies are very interesting because they accelerate changes in economic structures that lead to increased resource efficiency. In our project, we analyse how this development could be further encouraged. We introduce the term “co-evolution” describing a process of mutual learning between representatives of public policies and business. To this end we use system dynamic modelling in combination with integrated assessment. In our transdisciplinary research approach, we collaborate closely with stakeholders in industries and public policy using group-model-building. Data is collected in case study analysis with seven different companies producing sand, gravel, cement, concrete and services in logistics, construction and waste management. Both system dynamic and assessment model are based on Material-Flow-Analysis on different scales (company and region). It proves to be a valuable tool to ensure consistency of both models as well as data quality. First results show that different policies in waste-management, resource-management and settlement development have a strong effect on decision making in material and construction industries.
Share, Preserve, Adapt, Rethink – a focused framework for circular economy
Authors: Kyrö R K 
Published: November 2020

Abstract
The concept of circular economy has peaked in both popular and scientific discussion in the past few years. Notwithstanding, no specific definition for circularity in the context of existing buildings is available. This research details a framework of circular economy in the built environment, focusing on existing buildings. The paper employs a systematic literature review on circular economy within built environment. The majority of the reviewed articles date from 2016-2019, confirming the novelty of the research area. Based on the literature review, research on circular economy in the built environment has to date largely focused on designing to facilitate circularity in the future, or salvaging and recycling building materials for new construction. This paper suggests a literature-based framework comprising three complementary approaches to implementing circularity in the context of existing buildings: 1) Share; 2) Preserve; 3) Adapt, and; 4) Rethink. The transition toward a circular economy in the built environment requires structured approaches, like the one presented here. The presented framework allows researchers to expand their thinking on circularity in the built environment, while providing practitioners a selection of potential managerial approaches. The suggested circular approaches may be particularly useful for the longer-term strategy work of real estate owners and managers.
Circular Building Design for the Infill Domain: Materialisation, and Value Network study of the Niaga ECOR Panel innovation
Authors: Geldermans B , Tavakolly N , Udding H-J 
Published: November 2020

Abstract
Circular Building gained traction during the past decade in the Netherlands. Circular Building (CB) is rooted in concepts such as Circular Economy and Cradle-to-Cradle®, accentuating closing and continuing of material flows to establish sustainable resource cycles. CB implies that buildings and building components are designed to retain value, tailored for specific service lives and responsive to changing needs. This way, wasting of buildings and building components can be reduced or avoided. This paper revolves around circular materialisation and operation of building infill, such as furniture, partitions, and kitchens. The short to medium-long material cycles usually associated with those components provide potential benefits for circular resource management. The paper comprises a study into materialisation and operational performance of the Niaga ECOR Panel (NEP): an innovative cellulose board product. NEP aims to offer a healthy and circular alternative for conventional linear board products and value chains, adhering to multiple Sustainable Development Goals, notably: SDG11 (Sustainable Cities and Communities) and SDG12 (Responsible Production and Consumption). The study follows Circ-Flex assessment guidelines, anticipating operational performance through the supply, use, and reverse-supply chain. The findings indicate that the intrinsic properties of the NEP can enable circular infill value models, provided that networked actors remain aligned.
Urban community planning and spatial model construction supporting sustainable consumption and production
Authors: Zhang Y K , Yang Y C , Zheng J , Huang S 
Published: November 2020

Abstract
Introduction: Three main contradictions that accompany the urbanization process: population explosion and food demand, urban expansion and production space, production mode and energy consumption. The pressure of urbanization has caused a huge mismatch between production and consumption in space and mode. Analysing the status and trends of urban food system planning show that sustainable consumption and production are closely related to their spatial layout. Method: Take a simulated urban community sustainable food system as an example. Based on local production and consumption, distributed layout and resource recycling system. The model formulates a reasonable spatial planning strategy based on urban agriculture of different scales, technologies and efficiencies, quantifies the indicators of the productive community to suit different scales, and uses a python algorithm to simulate a spatial model with adjustable parameters. Results: Through the comparison and optimization of multi-plan spatial patterns, a sustainable consumption and production-oriented planning decision was formed, which was finally used to guide the productive community spatial planning project. Discussion: This model is only a preliminary attempt at food system planning, but ‘theory-simulation-design’ has proved the feasibility of productive community spatial planning and explored the path of sustainable urban communities that support sustainable consumption and production.
An attempt to create the holistic flow chart of forest resources
Authors: Wang Hongjun , Takano Atsushi , Tamura Ken Taro 
Published: November 2020

Abstract
The environmental development of a building has an important role to play in terms of the sustainable development of our society. Against this background, wood and wood-based products have lately attracted notable attention as promising construction materials due to then-unique environmental properties, such as renewability and carbon storage capacity. For the sustainable use of wood, a relevant balance between supply and demand of forest resources is significant. However, little work has been conducted on a comprehensive understanding of forest resources flow. The objective of this study was. therefore, to draw an integrated chart of forest resources flow including forest conditions, round wood production, wood product manufacturing, wood stock in buildings and waste management at the end of product life, mainly focusing on building material flow. The flow charts were drawn for five countries (Japan. Finland. Germany, Sweden and Canada) based on statistical data. Instead of directly showing numerical information, the chart is presented as an infographic in order to promote intuitive understanding of the contents. The chart is intended as a basis for the development of sustainable forest resource circulation. This paper focuses on introducing the chart as such ad briefly discusses how the chart can be utilized for further study in relation with SDGs.
