A Machine Learning Approach to Adapt Local Land Use Planning to Climate Change

The impacts on living conditions and natural habitats deriving from planning decisions require complex analysis of cross-acting factors, which in turn require interdisciplinary data. At the municipal level, both data collection and the knowledge needed to interpret it are often lacking. Additionally, climate change and species extinction demand rapid and effective policies in order to preserve soil resources for future generations. Ex-ante evaluation of planning measures is insufficient owing to a lack of data and linear models capable of simulating the impacts of complex systemic relationships. Integrating machine learning (ML) into systemic planning increases awareness of impacts by providing decision-makers with predictive analysis and risk mitigation tools. ML can predict future scenarios beyond rigid linear models, identifying patterns, trends, and correlations within complex systems and depicting hidden relationships. This article focuses on a case study of single-family houses in Upper Austria, chosen for its transferability to other regions. It critically reflects on an ML approach, linking data on past and current planning regulations and decisions to the physical environment. We create an inventory of categories of areas with different features to inform nature-based solutions and backcasting planning decisions and build a training dataset for ML models. Our model predicts the effects of planning decisions on soil sealing. We discuss how ML can support local planning by providing area assessments in soil sealing within the case study. The article presents a working approach to planning and demonstrates that more data is needed to achieve well-founded planning statements.

Optimizing the Integration of Building Materials, Energy Consumption, and Economic Factors in Rural Houses of Cold Regions: A Pathway

Limited material options and economic conditions significantly restrict the potential for energy efficiency improvements in rural houses in China’s cold regions. It is worth exploring how to propose suitable energy-saving renovation plans for rural houses in cold regions under practical constraints. By using Grasshopper within Rhinoceros 8 software, an algorithm integrates material selection, energy consumption calculations, and economic analysis. The method efficiently generates thermal optimization schemes, providing insights into energy use, costs, and payback periods. In a case study of a typical rural house in Daqing City, the optimized scheme achieved over 70% energy savings compared to traditional homes, with renovation costs amounting to less than 40% of residents’ annual income and a 2-year payback period. This significant improvement highlights the potential of the proposed method in enhancing the energy efficiency and economic viability of rural house renovations.

Efforts to improve preparedness need to be carried out comprehensively, involving collaboration between hospitals, government, fire department and the community.

Domestic, Not Private: Feminine Proposals for Carabanchel PAU Expansion, Madrid, Spain

This paper offers a gender-based analysis of collective space in the domestic realm, beyond privacy, produced in significant social housing case studies in the urban expansion of Carabanchel neighbourhood (Carabanchel PAU, Madrid, Spain). Designed at the beginning of the 21st century, this period involves the incorporation of women into young architectural teams. Thus, this study seeks to delve into the significance of this role through the detailed study of eleven cases. Focussing on the common spaces of housing buildings, these small elements seem to recall the passage from the safe to the unsafe environment, from the space of the reproductive labour to that of the intersectionality. Following this finding, we propose an incipient study of the transitional spaces between the private and the public, where contacts between neighbours and the exchange of care beyond the private sphere are celebrated, as well as the public representation of domestic life. The methodological approach has stablished four meaning aspects to analyse, related to inhabitants’ life and intended as architectural parameters: spaces for neighbourhood flows, both for residents and visitors; areas of activity and leisure, available for resident daily life; connections between these areas of activity and leisure and, finally, connections of the common areas with the dwellings. The aim is to investigate the extent to which the participation of women architects makes these spaces more effective for care giving—or simply, more suitable for the expansion of intimate life and socialisation with neighbours. The results provide optimistic data for the discipline and its capacity, through this type of sensitivity, to correct some of the errors in the system of production of public space.

Research on the Renewal of Multi-Story High-Density Urban Landscape Based on Property Rights Land—A Case Study of the Self-Built Liu Houses in Zherong, Fujian Province

Unlike in Western countries, land ownership in China is overwhelmingly vested in the state, and individuals cannot directly own private lands and build houses. Therefore, developers will contract the land to the government and build it into collective apartments. Against this backdrop, a different kind of multi-story, high-density self-built residential buildings is widespread in small towns along the southeast coast of China. These buildings were built between 1980 and 2000 by residents who acquired land-use rights from the government for compensation. The uniqueness of these buildings is what makes them incompatible with the most mainstream, government-led urban renewal model in China, resulting in a large area of dilapidated and aging areas. Zherong County, Ningde, Fujian Province, is a typical example town, with a large number of such self-built houses, known locally as Liu Houses. In this study, these residential areas were selected as typical research objects of “characteristics of residential small towns”. Combined with the property rights of the sample cases, the methods of diagram and quantitative analysis are used to summarize the causes of the three types of residential areas from the aspects of regional planning, land division, building construction, and renovation. In the early days, the planning of the Liu House was greatly influenced by the residents, and the construction and renovation of the building was led by the residents, which strengthened the diversity of the style. In the middle period, the government had relatively dominant control over the planning of Liu Houses, and supervision was conducted during the construction and renovation process, resulting in a relatively balanced power between residents and the government. In the later period, the houses were built and operated by the developer, and the residents no longer directly participated in the construction and renovation, so the unity of style was strengthened. At the same time, the study finds that, in the process of the formation of the style of the residential area, on the one hand, the property rights directly affect the style through its own physical land attributes, and on the other hand, it becomes the basis of the game between the government, residents, and the county environment through its own property rights, thus indirectly affecting the style. In conclusion, this paper may provide theoretical support and design reference for the renewal of the characteristic features of residential small towns.

EXPLORING THE POTENTIAL OF VEGETATION STRUCTURES (VS) AND LANDSCAPE ORIENTATION IN MINIMIZING THERMAL PERFORMANCE IN A TROPICAL CLIMATE: A FIELDWORK STUDY

The study investigates the impact of vegetation structure within two landscape orientations on thermal performance, a critical consideration in urban planning and environmental management. Given the increasing concerns about Urban Heat Islands and global warming, understanding how vegetation influences thermal regulation is essential. This research employed a quantitative method through field measurement studies, focusing on two single-storey semi-detached houses namely East Landscape Orientation (ELO) and West Landscape Orientation (WLO) located at Seri Iskandar, Perak Malaysia. The snowball technique was utilized to select the case study houses, ensuring a targeted approach to understanding the effects. Thermal Microclimate Data Logger and Indoor Air Quality Monitor Data Logger were used to measure environmental parameters for thermal conditions, ensuring consistent, reliable, and comprehensive data for analyzing thermal performance in both outdoor and indoor environments. The research findings reveal that the orientation of a house relative to the sun's path significantly impacts its thermal dynamics, with vegetation playing a crucial role in moderating these effects. ELO houses benefit from milder morning sunlight and effective afternoon cooling, while WLO houses experience higher outdoor and indoor temperatures due to intense sunlight and less efficient transpiration by vegetation. Vegetation on the west side provides shade and reduces heat absorption, improving comfort and energy efficiency. Understanding these dynamics can help homeowners and architects make informed decisions about landscape design, enhancing thermal comfort and energy efficiency in homes. This research also contributes to the expanding knowledge base on sustainable urban design by exploring the use of vegetation to enhance thermal performance.

Reducing residential cooling demand in a sprawling desert city through vertical urban densification

Traditional desert cities used a compact urban form since it provides benefits in terms of thermal comfort both in urban and interior spaces. However, many current desert cities have shifted to a sprawling model with isolated low-rise buildings, leading to longer travel distances, increased land use, inadequate public space, and higher demand for building cooling. Our study aims to investigate how vertical urban densification can reduce residential cooling demand in hot-dry regions. To achieve this, we compared single-family houses with high-rise multi-family houses in Hermosillo, Mexico. Eight case studies of real houses were selected, representing the city's building stock, including one- and two-story single-family houses, and high-rise multi-family houses. We use dynamic energy simulations to assess the effectiveness of changing building's shape against improving its insulation. Our results indicate that increasing vertical density leads to a reduction in the envelope-to-volume ratio, resulting in a significant decrease in cooling demand. Moving from a one-story single-family house to a high-rise multi-family house can lead to a 72 % reduction in annual cooling demand. Matching the façade material properties of single-family houses and multi-family houses reduces the cooling demands of the single-family houses by 16 %–31 %. However, they still have higher cooling demands compared to high-rise multi-family houses, suggesting that building form has a greater impact on cooling than thermal insulation. Our findings highlight the substantial energy savings achievable by transitioning from detached single-family houses to high-rise multi-family developments in desert cities.

Examining the Impact of Natural Ventilation versus Heat Recovery Ventilation Systems on Indoor Air Quality: A Tiny House Case Study

Adverse health effects can arise from indoor air pollutants, resulting in allergies, asthma, and other respiratory problems among occupants. Concurrently, the energy consumption of residential buildings, particularly concerning heating, ventilation, and air conditioning (HVAC) systems, significantly contributes to global energy usage. To address these intertwined challenges, heat recovery ventilation (HRV) has emerged as a viable solution to reduce heating and cooling demands while providing fresh ventilation rates. This study aims to investigate the indoor air quality (IAQ) of an experimental tiny house building equipped with an HRV unit by simulating real-life scenarios contributing to IAQ. The research evaluates the effectiveness of HRV compared to natural ventilation in managing particle matter (PM), total volatile organic compounds (TVOC), formaldehyde (CH2O), carbon monoxide (CO), and carbon dioxide (CO2) levels. This research significantly contributes to the understanding of the different ventilation strategies’ impact on IAQ in tiny houses and offers valuable insights for improving living conditions in a unique building typology that is underrepresented in the research literature.

Partners in crime: Convenience case study of Norwegian publishing cartel

The theory of convenience addresses white-collar and corporate crime. The theory is applied in this article to a case study of Norwegian publishing houses having to pay infringement fees because of competition act violation. Cartel members agreed and coordinated a boycott of a distribution channel. This article reviews the research literature on cartels before presenting the convenience case study. Combatting cartels is a matter of reducing the attractiveness and convenience of joining cartels. Guardianship, oversight, and controls are at the core of reducing deviance convenience. Detection is an element of oversight. However, detection is rare, as this case illustrated by email sent by mistake. Combatting cartels is a matter of control at the top of organizations where typically each chief executive officer (CEO) is involved. Therefore, the corporate compliance officer should never report to the CEO but rather to the chairperson on the board and to the external auditor.

Young families’ space adaptation in subsidized housing case study: Mataram city, West Nusa Tenggara Indonesia

ABSTRACT Indonesia’s 2020 census shows that 25.87% of the population comprises productive working-age millennials in the family-forming phase and demand affordable housing. To aid the low-income class in accessing the housing market, the government provides the Rumah Inti Tumbuh (RIT) or “growing core house” programme. This study examines the young families’ adaptation to utilize the available rooms, using mixed methods of observations, interviews, and architectural records. Study analyses employ the six layers’ theory of [Brand, Stewart. 1994. How Buildings Learn: What Happens After They are Built. New York, NY: Viking] to trace back the incremental process from the early home-making, motivation development, and adaptation strategy of the spatial usages in the post-reconstruction. The study concludes that young families needed to incrementally outmode the forms of provision even in the early occupation. The adaptive solutions gradually blurred the initial design idea provided by the developer. The home-making practices also accommodate daily activities connected with Islamic cultural, social, and intimate spheres.

Reports of my death are greatly exaggerated: The persistence of neoliberalism in Britain

Recent declarations of the end of neoliberalism in the United Kingdom, especially since the Covid-19 pandemic, are underpinned by diffuse and unstructured understandings of the neoliberal state. We argue that state intervention is both necessary and unavoidable under neoliberalism. This article shows that the ‘market-based’ reforms and the ‘rollback of the state’ that overtly characterise neoliberalism are heavily reliant upon public policy and entail an ongoing role for state intervention both over time and across economic sectors. Using sectoral case studies of housing and water from within the United Kingdom, we demonstrate, through a tight analytical framing of both financialisation and commodification, the variegated though crucial role of the neoliberal state in restructuring provision to facilitate financialised accumulation and their transformations in response to the contradictions, dysfunctions and limitations of neoliberalised social reproduction.

Optimization and Renovation Design of Indoor Thermal Environment in Traditional Houses in Northeast Sichuan (China)—A Case Study of a Three-Section Courtyard House

The three-section courtyard is the most representative traditional residence in the traditional villages in northeast Sichuan. As a unique cultural landscape, it carries the local historical style and cultural connotation. However, the high temperature weather in summer leads to a poor thermal environment in traditional residential buildings, which cannot meet the needs of building users for human thermal comfort, and the wall is the most critical factor affecting the indoor thermal environment. Therefore, to optimise the indoor thermal environment of traditional residential buildings, this study designed four groups of wall renovation schemes according to the original traditional residential buildings and modern technology, and simulated and verified the feasibility of the building renovation schemes by using Design Builder. Then, the four groups of wall renovation schemes were compared and tested based on the Design Builder. Comparative results of the thermal-performance evaluation index revealed that compared with Case 1 and Case 2, the building refrigeration energy consumption of Case 3 in the hottest week was the least, only 427.7 kW·h, which indicates that the external wall renovation scheme using aerated concrete blocks had the best thermal insulation and energy-saving effects. The cooling energy consumption of Case 4 in the hottest week was 422 kW·h, which was 4.3 kW·h less than that of Case 3, indicating that the wall renovation scheme with an air inter-layer had better thermal insulation and energy-saving effects. The refrigeration energy consumption of Case 7 in the hottest week was only 409.8 kW·h, which was 4.19% lower than Case 3 (without insulation material), indicating that the scheme of selecting central insulation and extruded polystyrene board (XPS) had better thermal insulation and energy-saving effects in practical projects. In summary, the above transformation scheme not only improves the indoor thermal environment of traditional residential buildings, but also provides guidance for architectural designers on green, energy-saving and sustainable design.

Life cycle integrated analysis of thermal, environmental and cost performance of building envelope system: Small house case study considering grid mix change in Brazil

Dwellings with inadequate envelopes tend to present higher energy consumption, consequently, higher energy costs and significant environmental impacts. However, improving performance may increase initial costs. Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) are used to independently evaluate the environmental and cost implications of thermal performance. Thus, it is necessary to help designers synthesize these criteria. This article analyzes the thermal, environmental, and cost performance of a single-family house in Brazil’s coldest climate zone with alternative conventional and innovative construction systems. The method has three steps: research problem identification and case study definition; criteria assessment (energy simulation, LCA, and LCC); results analysis. Investments in the building envelope can reduce 20% of energy consumption per year, 12% of Global Warming Potential emissions, and 17% of Cumulative Energy Demand. The assessment included two different scenarios of the electricity grid mix. The scenario with cleaner energy had a 25% reduction in the environmental impact. Thus, future potential changes in the electricity grid mix must be considered in building assessment because of the typically long building life cycle. The envelope adaptations improve environmental and thermal performance and influence the entire life cycle costs due to energy consumption. Thus, the results help in decision-making.

The Design of Earthquake Evacuation Spaces Based on Local Wisdom: A Case Study of Traditional Houses in South Sulawesi

Indonesia is situated on the Ring of Fire, which causes a lot of earthquakes. On the 28 September 2018, there was an earthquake in Palu, Sulawesi Island, Indonesia, which was one of the strongest shakings since 1980. Surprisingly, most traditional houses in Sulawesi survived. There has been some research on adapting traditional house structures to modern residential buildings. The limited availability of wood and complicated construction make adapting wood structures to current conditions challenging. The purpose of this study is to analyze space organization in ten traditional South Sulawesi house designs. A possible evacuation route can be found through the analysis as the first space for expeditiously escaping from an earthquake. In addition, modernizing the layout of a traditional South Sulawesi house and introducing it to local people was easy since they were familiar with the design. A deep analysis of spatial organization and its interrelations can help develop realistic designs, plans, and knowledge, thus improving the quality of residential projects. A descriptive qualitative method was used as a research method. Data were collected from field observations, brief interviews, and literature reviews. In order to analyz thee data, ORA-LITE was used to redraw the data and create the charts. It was found that different cultures have different evacuation spaces, in this case the Bugis tribe and the Toraja tribe. A corridor and kitchen were the most strategically located areas that could possibly be used for evacuation. Considering the differences in culture among tribes, designing evacuation spaces based on local culture was important. A recommendation based on this finding can also be made to the government of South Sulawesi in the design of residential houses.

A Liveability Framework for Medium to High Density Social and Affordable Housing: An Australian Housing Case Study

ABSTRACT The private rental market costs are placing a burden on household budgets, thus significant pressure is on governments and private housing organisations to supply more social and affordable housing solutions. This research evaluates the key elements of medium- and high-density liveable and accessible social and affordable urban housing precincts. Focusing on investigations into an Australian housing case study, the authors establish a liveability framework to improve understanding of whole-of-life needs. Through a comprehensive literature review, a case study and a series of in-depth interviews with key stakeholders from the housing sector five key elements were identified. These key elements include: (1) Liveability, (2) Accessibility, (3) Value equation, (4) Regulatory and policy environment, and (5) Adoption and overcoming barriers. The liveability framework will form the basis of a set of quality standards that can be used to guide precinct planning, design development and management.

Comparing the whole life cycle carbon impact of conventional and biogenic building materials across major residential typologies in Ghana and Senegal

Across West African built environments, patterns of high greenhouse gas emissions are driven by the widespread importation of high embodied carbon building materials by a largely self-built industry and recurring operational carbon costs driven by increased access to fossil-fuel based energy services. Using a whole life cycle assessment (LCA) of major residential typologies in two case-study West African countries, Ghana and Senegal, this paper compares the greenhouse gas emissions of imported building materials with local alternative biogenic and geogenic materials within conventional housing typologies. Results indicated that locally sourced biogenic and geogenic materials may be rendered ineffective in buildings if future typologies do not address the effective space density, passive design strategies and increased renewable energy-use. For the building typology with the highest carbon footprint, the Ghanaian detached house, the substitution of conventional building materials with non-fired earth masonry did not have any significant impact. As shown in the housing typology with the lowest operational to embodied carbon ratio, the Senegalese vertical housing case study, optimizing the thermal mass design of earthen building envelopes can significantly drive down lifetime operational carbon emissions. For tropical low-rise building typologies dominated by high roof area to building volume ratios, roof insulation could drive down operational carbon of the building by a factor of 4 to 5. Although each additional storey results in approximately 10–12 % increase in greenhouse gas emissions, the vertical expansion of housing represents an important driver in reducing greenhouse gas emissions per capita.
