This investigation explored (1) correlations between midlife and older adults’ air quality perceptions with objective particulate matter 2.5 (PM_2.5) and diesel PM, and (2) correlations between air quality perceptions with health-related attributions among a sample of midlife and older adults (n = 66) living in or around senior affordable public housing sites in California’s San Francisco Bay Area. The adapted air quality perception scale was used to measure perceptions of air quality, while health-related attributions were obtained from the vitality plus scale (VPS), with higher values indicating worse perceptions of air quality and poorer responses to health-related attributions, respectively. Self-reported data were linked to zip code level PM_2.5 and diesel PM obtained from the CalEnviroScreen 4.0. All correlations were evaluated using Spearman’s rank correlations. The mean (SD) age was 70.6 (9.1) years, and 75.7% were female. We observed moderate, positive correlations between both PM_2.5 and diesel PM with three domains: perceptions related to protection measures against air quality, emotional/mental perceptions, and sensorial perceptions. We also found evidence of moderate, positive correlations between the domains of physical symptoms, perceptions related to protection measures against air quality, and emotional/mental perceptions with health-related attributions, such as sleep-related items and feelings of restlessness or agitation. Results from this exploratory study suggest that midlife and older adults’ perceptions of air quality may be moderately related to both objective air quality data and certain health behaviors and symptoms. Findings underscore the importance of considering individual perceptions as an additional area in public health strategies aimed at protecting midlife and older adults from the impacts of air pollution.

Passivhaus (PH) has gained global recognition for its energy-efficient features despite a 5% to 10% higher construction cost than traditional houses, especially within European countries. However, its adoption and popularity have not met the same fate in other countries like New Zealand. The higher upfront cost has been critical to the slow adoption of the PH movement in New Zealand. This study aimed to demystify the mist around the cost of PHs with a focus on the effects of drivers and barriers on their life cycle costs (LCCs). As such, a systematic literature review was conducted to provide a comprehensive understanding of the cost implications associated with PH. Using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) review method, we examined 71 past studies on PHs from 2005 to 2023. We found that the drivers of PHs include reduced heating demand, increased thermal comfort, and indoor air quality (IAQ). Research showed that the rising market for PHs is fueled by climate change, environmental awareness, innovative materials and technologies, individual commitment, improved regulations, pilot studies, research efforts, and governmental funding and initiatives. However, PHs face significant challenges such as increased complexity, advanced technology, higher initial investments compared to conventional and low-energy houses, national requirements, overheating, difficulties in affording the technologies, and a lack of options in the market. Despite the wealth of research on the economic aspects of PH, there is a lack of in-depth studies exploring the LCC of PHs focusing on cost commitments and benefits. Such studies are essential for assessing and optimising the cost-effectiveness of PH, considering different climates and regions, and comparing them with other low energy standards. The findings of our review provide a crucial focus for PH stakeholders in assessing the long-term financial viability of PH projects, thereby improving decision-making and facilitating effective planning for sustainable and cost-effective housing.

Social capital plays a crucial role in enhancing community resilience during flood disasters. This study investigates the influence of social capital on community resilience in Nanjing, China. Social capital is composed of five aspects: cohesion, collective efficacy, sense of belonging, trust and reciprocity and informal social control. Factor analysis and multiple regression analysis are employed to analyze the dimensions of social capital and its impact on community resilience. Our results demonstrate that social cohesion and collective efficacy are the most representative factors of social capital. Reformed housing communities typically have higher cohesion than those in commercial and affordable housing. Affordable housing communities in flood-prone areas have higher collective efficacy but lower trust and reciprocity. Commercial housing communities have higher informal social control but have great internal differences in collective efficacy. We strongly urge government decision makers to enhance flood resilience by fostering social capital within local communities. Full article

Accessibility is closely related to residents’ well-being and quality of life and is a potential indicator of social equity. This study aims to present a methodology for assessing the combined equity of living service amenities (LSAs) based on accessibility. This study focuses on fourteen types of LSAs in six dimensions and improves the three-step floating catchment area (3SFCA) model by considering the behavioral demand characteristics of different age groups. Taking the main built-up area of Xi’an as an example, the modified 3SFCA model is applied to assess the accessibility of LSAs, and the supply–demand index is used to measure the supply and demand level of the horizontal dimension. Furthermore, random forest regression was used to screen the key socioeconomic indicators affecting the accessibility of LSAs, and then the binary spatial correlation local index was used to reveal the spatial distribution characteristics between LSA accessibility and key socioeconomic indicators in the vertical dimension. Finally, the comprehensive equity of LSAs is evaluated by space superposition. The results showed that there was a serious imbalance between the supply and demand of LSAs in Xi’an’s main built-up area, with polarized oversupply and weak supply areas, especially for accessibility to low-grade LSAs. Accessibility is relatively low for children and young and middle-aged groups, and intergenerational inequalities were particularly pronounced among them. The lower-income group was generally at a disadvantage in accessing the high-demand amenities, and those who resided in affordable housing in the periphery of the city were more likely to face social exclusion. This study emphasizes the importance of distributing urban resources equitably among different social groups, which can help decision makers achieve a balance between horizontal equity and vertical equity in the allocation of urban LSAs and promote spatial equity and sustainable social development.

The Chinese government’s recent low-income housing scheme aims to tackle housing challenges faced by the urban floating population. A notable shift in this initiative is the focus on the job–housing balance. This study proposes that the spatial interaction between land designated for affordable rental housing and land for commercial facilities serves as a fundamental metric for evaluating this equilibrium, providing insights into the effectiveness of China’s nascent affordable housing efforts. Drawing on post-2021 data, when China’s revamped affordable housing policy took effect, our research examines the spatial distribution of affordable rental housing and commercial service land in Shanghai. By employing coupled coordination models and local entropy metrics, we delve into the supply equilibrium and pragmatic interrelation of these land types. Our findings reveal localized clustering in the spatial arrangement of rental and commercial land within Shanghai. Zones in the urban core exhibit a supply balance, while the peripheries display diminishing accessibility between these land types. Core urban areas have a lower supply balance but higher accessibility, whereas urban fringes face both low supply balance and low accessibility. These study outcomes have significant implications for strategic planning and the construction of affordable rental housing. Full article

Canada has been experiencing a significant housing crisis in recent years, especially in remote and Indigenous communities, yet most of the existing construction approaches have not been rapid, sustainable, and affordable enough to meet community needs. To address this challenge, this study explores the feasibility of 3D printed (3DP) housing and develops a design that is informed by Indigenous housing requirements and is realized through a physical design prototype tailored for the implementation of 3DP homes. Site visits and community engagement were integral parts of the research to help deliver invaluable insights that guided the design process, ensuring cultural sensitivity and inclusivity. The prototyped 3DP design offers efficient and sustainable solutions customized to the unique cultural and climatic needs of Indigenous communities in Canada. The final 3DP design seamlessly integrates traditional Indigenous architectural elements, such as a circular shape inspired by pit houses, with modern construction techniques, yielding a flexible, sustainable, and culturally pertinent home design. Future research work will be focused on how the proposed 3DP design can be adapted to enable mass customization to accommodate the diverse needs and preferences of Indigenous communities across Canada.

Economic recession from the coronavirus outbreak continues to have negative rippling effects on local and international financial investments in public–private partnership (PPP) projects in Ghana, a developing country. Together with poor reports on operating cash-inflows for PPP projects such as those covering schools, hospitals, railways, fishing harbors, cocoa warehouses, recreational parks and affordable housing, there is an urgent need to develop and institutionalise sustainable and robust financial risk management measures. These measures are meant to mitigate financial losses, promote sustainability practices and prolong the longevity of infrastructure developments within PPP pacts. Therefore, this study aims to assess the mitigation measures of PPP infrastructure management in Ghana. Primary data from survey questionnaires were utilised in this study, with the data obtained from PPP practitioners and experts. Data were grouped into project type, sectors and practitioners of PPP projects to aid the analysis using tools such as the Kruskal–Wallis test, the Mann–Whitney U test and factor analysis. The results demonstrate sustainable and green finance, the innovative skills and competencies of project teams, green financial risk models and inclusive cost reduction strategies as crucial to minimising financial risks in PPP project delivery. These findings have significant implications for PPP practitioners and researchers in Ghana and similar developing countries to understand and develop measures to respond to financial risks for sustainable PPP project development and future research studies.

Despite state efforts to enhance affordability, access to adequate housing, deemed a fundamental human right, remains a global challenge. Projections indicate a looming housing deficit affecting 1.6 billion people by 2025, necessitating an integrated approach aligning environmental preservation with housing development. Circular Economy (CE) principles are identified as instrumental in advancing sustainable Social Housing Policies (SHPs). A Systematic Literature Review (SLR) placed best practice documents establishing a positive correlation between CE principles and increased social housing supply. The circularly built environment is recognised for reducing waste, carbon emissions, and resource depletion. However, this research proposes a nuanced perspective, asserting that integrating CE principles addresses housing needs and fosters environmental sustainability, job creation, and economic growth. Crucially, community, government, and the circular economy emerge as pivotal actors in overcoming challenges inherent in SHPs. This study contributes significantly to the discourse on housing policies and sustainability, advocating for an inclusive and environmentally conscious approach to the global housing deficit.

Rapid urban growth necessitates focused attention regarding its policy and governance to ensure affordable housing, transparent and efficient real-world systems, reduce social inequalities, and promote sustainable development. This study delves into the semantics and ontology for developing a Land Administration Domain Model (LADM) profile in the context of Pakistan’s Land Administration Systems (LASs), which currently face issues due to manual record-keeping, lack of transparency, frauds, and disintegration. Establishing a baseline through Record of Rights (RoR) and Property Information Report (PIR), alongside surveying and mapping procedures defined by laws and rules, forms the foundation for LADM profile development. This study explores the transition from manual LAS to 2D/3D representation, using LADM as a conceptual guideline. The LADM profile’s three key packages—PK_Party, PK_Administrative, and PK_SpatialUnit—a sub-package, and external classes are examined, with proposals for digitalisation and modernisation. Additionally, the study includes expert consultation, and highlights the significant support that the LADM implementation offers to achieve Sustainable Development Goals (SDGs) in Pakistan. In conclusion, the study underscores the need for a comprehensive and inclusive approach to address organisational overlaps and ambiguities within LAS, positioning PK LADM as a transformative force for sustainable urban LAS in Pakistan, aligning with broader SDGs. Recommendations include exploring realistic land valuation, integrated ownership and location verification systems, addressing historical survey data challenges, and promoting wider stakeholder adoption for sustainable 2D/3D urban LAS using LADM and its edition II as a way forward towards the creation of a smart city and digital twin.

Introduction: An estimated 5800 to 46,500 lives are lost due to homelessness each year. Experiencing homelessness and poor health are cyclically related, with one reinforcing the other. Mobile programs, which include vehicles that travel to deliver care, and street medicine, the act of bringing care to spaces where PEH live, may play a role in alleviating this burden by providing trusted, affordable, and accessible care to this community. Methods: We conducted a scoping review of peer-reviewed literature on the role of mobile clinics and street medicine in providing care for PEH by searching PubMed, Embase, and Web of Science on 10 August 2023. Articles from 2013 to 2023 specific to programs in the United States were included. The protocol was developed following the PRISMA-ScR guidelines. The primary outcome was the role of mobile programs for persons experiencing homelessness. Results: A total of 15 articles were included in this review. The descriptive findings emphasized that street medicine and mobile clinics provide primary care, behavioral health, and social services. The utilization findings indicate that street medicine programs positively impact the health system through their ability to defer emergency department and hospital visits, providing financial benefits. The comparative findings between mobile programs and office-based programs indicate current successes and areas for improvement. Discussion: Mobile clinics and street medicine programs that serve PEH provide a wide range of services. While more significant structural change is needed to address healthcare costs and housing policies in the United States, mobile clinics and street medicine teams can improve healthcare access and the healthcare system.

This research focuses on assessing the environmental impact of heating and cooling systems in public housing projects, built between 2000 and 2020, in Tucuman, Argentina. It considers current and projected climate change scenarios. The study compares existing conditions with improvements suggested by IRAM 11603 for a thermo-energetic transition. Anticipating future energy consumption changes is vital for proposing sustainable retrofitting options to enhance affordability and energy efficiency, while ensuring occupants’ thermal comfort. A public housing prototype in Tucumán serves as the case study. The methodology combines energy simulation and Life Cycle Assessment (LCA) to analyze current and future energy demands. The results show climate change’s potential impact on housing thermal behavior and the necessity for improvements. In the base case, cooling demand exceeds 11 kWh/m²·year, while heating demand decreases by approximately 4 kWh/m²·year. Rehabilitation could reduce cooling demand by 57% and heating demand by 32.5%, considering future climate scenarios. Active architectural strategies are proposed for enhancing thermal performance and reducing energy consumption and carbon dioxide emissions. This study underscores the importance of analyzing future scenarios and implementing strategies for the thermo-energetic transition of existing social housing. Full article

Egg production is amongst the most rapidly expanding livestock sectors worldwide. A large share of non-renewable energy use in egg production is due to the operation of heating, ventilation, and air conditioning (HVAC) systems. Reducing energy use, therefore, is essential to decreasing the environmental impacts of intensive egg production. This review identifies market-ready alternatives (such as heat pumps and earth–air heat exchangers) to traditional HVAC systems that could be applied in the industrial egg sector, specifically focusing on their use in temperate and continental climates. For this analysis, energy simulations were run to estimate the typical thermal loads of caged and free-run poultry housing systems in various Canadian locations, which were used as examples of temperate and continental climates. These estimations were then used to evaluate alternative HVAC systems for (1) their capability to meet the energy demands of egg production facilities, (2) their environmental impact mitigation potential, and (3) their relative affordability by considering the insights from a systematic review of 225 relevant papers. The results highlighted that future research should prioritize earth–air heat exchangers as a complementary system and ground source heat pumps as a stand-alone system to reduce the impacts associated with conventional HVAC system operation in egg production.

This paper demonstrates the macro dynamics of housing and disability by comparing pressures on a broad range of issues related to housing and disability across states. Despite the growing population of adults with disabilities in the United States, research on the national-level relationship between housing and disability has been largely absent and little attention has been paid to accessibility, housing affordability, or the prevalence of involuntary movement and relocation for adults with disabilities. Using national data from the 2020 American Community Survey (ACS), we examine the multi-dimensional nature of housing, through cost burdens, upkeep, and maintenance, renting vs. ownership, and types of housing prevalent in the United States, and argue that this creates a paradox of livability vs. affordability for adults with disabilities. These state-level trends in the cost and livability of housing environments by state show that housing conditions and housing costs are inversely associated for adults with disabilities. These macro-level conditionalities are not uniform but vary by housing type and location across the country, creating specific paradoxes in each state. We assert that housing itself is one of the key mechanisms that can support or hinder the long-term well-being of persons with disabilities living in the community, through the presence or absence of both physical space and facilities in the home. Ultimately, housing conditions and affordability need to be considered primary factors in the study and support of persons with disabilities and these considerations must be tailored to state and local housing dynamics to meet persons with disabilities where they live.

Access to affordable housing has a significant impact on the quality of lives of households and the overall well-being of communities. The enabling approach is recognized internationally as a mechanism for housing delivery, shifting the government’s role from that of a direct provider to that of an enabler within housing markets. In line with its Vision 2030, Saudi Arabia aims to transition its role from a direct housing provider to an enabler. This study aimed to assess the extent to which enabling strategies have been implemented within the Saudi Arabian context. This research was conducted based on a desktop study of the key literature, analysis of secondary data, and content analysis of the collected documents to address the research aim. The study found that housing costs, traditional land tenure, and insufficient financing are major housing challenges, intensified by high lending interest, lack of investor diversity in housing types, and lack of long-term funding from financiers. Also, slum developments are limited to providing street access, without addressing the overall conditions and the level of services. In addition, the costs of obtaining permits and implementing building regulations have contributed to housing shortages in the country. On the other hand, real estate developers of different scales undergo a classification and qualification system to increase their capacity for housing supply. To address these challenges, the Saudi government has implemented an enabling approach, serving as a provider for low-income and vulnerable groups through the Developmental Housing Program. The government also encourages local manufacturing of building materials to boost the construction industry. The present study recommends that the government enhance existing instruments to enable access to affordable housing. Full article
