Complex stimuli in urban environments often lead to cognitive fatigue in residents. As a result, there is a growing demand from residents for restorative environments. Previous research has shown that the pure natural environment in the wild can help people achieve cognitive restoration. However, little attention has been paid to cognitive restoration through exposure to green infrastructure. Based on Attention Restoration Theory (ART), this study conducted an eye-tracking experiment in a controlled laboratory environment to investigate the effects of two view types, green infrastructure and urban, on individuals’ cognitive restoration. The results show that green infrastructure has a positive effect on the cognitive functioning of the participants in the experiment. The positive effect of green infrastructure on cognitive restoration is reflected in the restoration of directed attention. Less cognitive effort is an important factor contributing to cognitive restoration. Nature-relatedness plays a vital role in the eye movement behaviour of individuals when viewing landscape pictures and in the restorative benefits of cognition.

Traditional rural houses are characterized by high energy consumption, low energy efficiency, waste of energy resources, and high carbon emissions, which are detrimental to China's energy consumption as well as to the environment. It is therefore important to promote green rural housing construction. However, rural villagers' low level of participation has led to a dearth of successfully implemented green rural housing projects, a situation that a lack of relevant research has no doubt contributed to. This paper therefore studies the factors influencing villagers' participation in green rural housing projects based on Bourdieu's theory of practice. A questionnaire-based survey was conducted in Yancheng, China, and descriptive analysis, analysis of variance and multivariate ordered logistic regression analysis were performed to understand the participation behavior of villagers and influencing factors of villagers' participation in green rural housing construction. Results indicate that participation of the surveyed villagers is generally not high, and most villagers participated superficially. No differences were detected in villagers' total participation in terms of gender, leisure time, housing type, government propaganda, government management, and government role orientation. Moreover, social network, social economy, construction cost, interest appeals, attention to current affairs, awareness of green environmental protection and total family population are found to affect villagers' total participation. The findings will help the government devise measures to encourage villagers to actively participate in the construction of green rural housing, and thereby realize the goal of low carbon sustainable development of rural communities.

3D printing technology is currently one of the fast-emerging technologies in the infrastructure construction field. Ancient Sub-Saharan African building construction made extensive use of a wide range of earthen materials and vernacular structures. The main goal of the research discussed in this paper is to learn from historical building construction in Africa and adapt the methodology, material use, and geometry or form to 3D print sustainable and green residential houses in tropical and arid regions. The study addresses the current 3D printing technology for construction of houses using Sub-Saharan African historical sustainable and green materials such as cob, bamboo, and hemp-material based structures. Earthen materials are cost-effective, naturally insulated, and environmentally friendly, which makes them stand out from other sustainable construction materials. Two main geometry models are designed in this study for a 3D printing construction method based on the Sub-Saharan African historical housing forms. Moreover, the study contributes to achieving a green building that satisfies the UN sustainable development goals.

Determining how to reasonably protect, upgrade, or rebuild old communities, deciding how to use the material resources they contain, and the generation of construction and demolition (C&D) waste are urgent problems faced in the process of urban renewal in Tianjin, China, that require solutions. In this study, brick and concrete housing structures in the downtown area of Tianjin, China, are considered as an example, and a phased renewal plan is proposed. Based on the nuclear density analysis method and the standard deviation ellipse method, the spatial agglomeration trends and distribution directions of the used bricks that will be produced in the city center during each demolition stage are investigated. The results demonstrate that the overall brick material resources are unevenly distributed; their density will increase over time, and the density core will present a trend of first gathering and then dispersing. Based on the spatiotemporal distribution of resources, it is necessary to formulate an urban resource recycling system to achieve sustainable development.

Although many studies have shown that housing wealth impacts household consumption behavior patterns, they have not incorporated housing characteristics into their research framework. Against the background of China’s reformed housing system, this study therefore constructs a theoretical framework of housing differences, credit constraints, and household energy consumption by adopting sample data from China Family Panel Studies (CFPS) of 7064 households in 25 provinces, municipalities, and autonomous regions in China. Multiple regression methodology is used based on the emission peak and carbon neutrality goal proposed by the Chinese government in 2021. The results show that housing differences significantly impact household energy consumption; housing assets have a significant wealth effect on household energy consumption; energy consumption of house owners increases due to the appreciation of their housing; and that the housing proportion of a household’s gross assets has a significant negative impact on household energy consumption. Furthermore, based on spatial distribution, it is found that the energy consumption level of households with housing properties in the developed regions of central and eastern China is significantly higher than that in the western regions. The study provides empirical evidence for China to build a linkage mechanism between energy policy and real estate policy and provides empirical support for the implementation of differentiated policies of energy consumption.

Over the past several decades, the rapid growth of Southwestern United States desert cities is creating significant climate and water scarcity challenges. City planners are using green infrastructure to mitigate these challenges and develop more livable, sustainable, and resilient communities. This study uses hedonic pricing modeling (HPM) to evaluate how constructed wastewater wetlands impact home values integrated into the project design. It compares Crystal Gardens in Avondale, AZ, consisting of 14 engineered wastewater filtering ponds, to nearby neighborhoods with desert landscaping. HPM revealed higher values for Crystal Gardens homes overall (7%) and significant increases for homes on the ponds (14%). Results demonstrate the economic value of integrating water-related infrastructure in desert cities for home sales. For a more accurate benefit assessment, additional research is needed on how the ecosystem services provided by these constructed wetlands contribute to greater property values.

The construction industry is one of the three largest carbon emitting industries in the world, accounting for up to thirty percent of global greenhouse gas emissions each year. Since traditional cast-in-situ building operations significantly contribute to these emissions and cannot therefore meet green building requirements, prefabricated buildings have come in to their own as a construction method that effectively reduces carbon emissions. Although studies have been conducted in to reducing carbon emissions by using prefabricated techniques at the building construction stage, none have focused on the reduction of carbon emissions by using prefabricated instead of cast-in-situ decoration systems. This study therefore used a case study in China to evaluate the carbon reduction potential of prefabricated decoration floor systems compared with traditional cast-in-situ decoration floor systems, and to also consider the carbon reduction pathways of four different types of prefabricated floor system from the perspectives of work methods and materials. Since the case study results showed that the carbon emissions reduction of the prefabricated floor system was 69.7%, or 101.5 kg CO2e per cubic meter, it can be concluded that there is a significant carbon reduction potential for using a prefabricated decoration floor system compared with a traditional cast-in-situ decoration floor system. The key contribution of the study is that it provides valuable references for interior decoration practitioners and decision makers when considering ways to reduce carbon emissions through prefabricated decoration floor systems.
建筑业是世界上最大的三大碳排放行业之一，每年占全球温室气体排放量的30%。由于传统的现浇建筑作业对这些排放有很大贡献，因此不能满足绿色建筑的要求，预制建筑作为一种有效减少碳排放的建筑方法而脱颖而出。虽然在建筑施工阶段通过使用预制技术来减少碳排放的研究已经进行了，但没有人关注通过使用预制而不是现浇装饰系统来减少碳排放。因此，本研究以中国为例，对比传统现浇装饰地坪系统，评估了预制地坪系统的减碳潜力，并从工作方法和材料的角度考虑了四种不同类型的预制地坪系统的减碳途径。由于案例研究结果表明，预制地板系统的碳排放量减少了69.7%，即每立方米101.5 kg CO2e，因此可以得出结论，与传统的现浇装饰地板系统相比，使用预制装饰地板系统具有显着的碳减排潜力。本研究的主要贡献在于为室内装饰从业者和决策者在考虑如何通过预制装饰地板系统减少碳排放提供了有价值的参考。

Passive heating, lighting, and ventilation techniques in historic buildings and their sustainability in conjunction with new designs are essential to maintaining a greener, ecological environment. This article describes a framework for identifying and disclosing the passive survival strategies and resulting solutions applied to historic baths in Anatolia. The aim is to first increase knowledge and awareness of ancient systems and to discuss and examine their contemporary inspirations and considerations of existing and new construction technologies. A total of four baths from the Roman, Byzantine, Principalities and Ottoman periods in Anatolia were selected. Their original heating, lighting, and ventilation systems were determined largely through on-site observations, literature review, and archival sources. The results indicate that in today’s modern residential, industrial or commercial buildings, reflections of these ancient technologies and traditional concepts can be observed as the main source of inspiration. They can be seen either in the form of light pipes, underfloor heating systems, or a double-skin façade. The old technologies and solutions of historic baths are mostly sustainable and ecological. Looking back at these historic technologies can inspire further ecological design developments and symbiotic implementation possibilities in new building designs.

The courtyard is an ancient outdoor design space surrounded by walls or buildings, acting as a microclimate modifier in hot-dry climates. This is related to its geometry, such as high proportions of height-to-width (H/W) and north-south (NS) orientation by providing shade and decreasing heat stress on hot summer days. However, its effect during winter still needs to be discussed, especially in hot summer and cold winter conditions (such as in semi-arid climates). This research studies the winter thermal comfort of a typical courtyard geometry suitable for hot summer conditions in a semi-arid climate. A literature review supports the identification of typical courtyard geometry addressed for hot summer conditions. Then, field measurements of the external surface temperature of courtyard interior orientations, microclimatic variables, and the Predicted Mean Votes (PMV) of occupants inside the courtyard were performed. The results indicate high correlations between PMV and courtyard interior orientations with the H/W ratio regarding cold stress. Thus, north-east and South-East orientations and H/W ratio less than (< 0.8) are recommended for better winter environmental conditions in semi-arid climates.

This paper discusses the design of a net-zero single-family house in Chattanooga, Tennessee, which was proposed for the 2022 Solar Decathlon Design Challenge entry. The site was in a 100-year flood zone and registered as a national and local historic district. The interdisciplinary team consisted of University of Tennessee Chattanooga (UTC) students from the interior architecture and engineering departments who embraced the challenges of the local climate and the restrictions of the historic district guidelines. This entry, Moc House, focused on the integration of passive design and active HVAC systems including photovoltaic systems in the process. In responding to recent housing market changes in Chattanooga due to the COVID-19 pandemic, a young professional couple in their 30s who have two children was identified as the target market which guided the space planning. Market analysis, including ROI, was conducted in addition to construction cost calculations. Building materials were selected to enhance the durability and resilience of the house structure. Finally, energy analysis was conducted to check the project’s Home Energy Rating using Ekotrope and found it less than zero.
