High-Resolution Mapping of Urban Residential Building Stock Using Multisource Geographic Data

The rapid pace of urbanization and the increasing concentration of populations in urban areas have generated a substantial demand for architectural structures, resulting in a significant increase in building stock and continuous material flows that interact with the environment. This study emphasizes the importance of high-spatial-resolution mapping of residential building stock for effective urban-construction resource management, planning, and waste management. Focusing on Xi’an as a case study, the research develops a comprehensive framework for mapping urban residential building stock by integrating diverse data dimensions, including temporal, spatial, network, and multi-attribute aspects. The findings indicate that between 1990 and 2020, approximately 4758 residential communities were established in central Xi’an. The analysis of seven key residential construction materials revealed that the building stock escalated from 1.53 million tons to 731.12 million tons, with a steady spatial expansion of material distribution. The study attributes this growth to factors such as population increase, economic advancement, and policy initiatives, which, in turn, have driven the demand for residential building materials and reinforced the interdependence between urban expansion and residential construction development. Remarkably, from 1990 to 2020, the population surged by 2.1-fold, the economy by 66-fold, and the stock of residential building materials by 477-fold, indicating that the growth rate of material stock consistently outpaced that of both population and economic growth. Over the past three decades, the rapid expansion of residential buildings has led to the encroachment of urban ecological spaces by concrete structures. The methodology proposed in this study for quantifying building material offers valuable insights for policymakers and urban and environmental planners to foster responsible resource consumption and supports component-level circularity in the built environment.

Biodiverse residential development: A review of New Zealand policies and strategies for urban biodiversity

Urban residential development is expanding globally to accommodate increasing housing demand, greatly impacting biodiversity and human wellbeing. Enhanced sustainability of these developments requires an integrated approach to conserving, supporting, and restoring biodiversity through the built environment and understanding the implications of residential development policies, regulations, and guidelines. This paper details a review of current New Zealand policies, strategies, planning documents, and design guidelines that inform urban design and planning at national, regional, and local levels. Three major gaps in biodiversity considerations and opportunities for improvement in residential developments were identified. Firstly, current policies and strategies tend to protect significant indigenous habitats, but the interventions required to improve or retain biodiversity in residential developments are not explicitly considered. Secondly, there is a need for design guidelines with explicit biodiversity outcomes. Thirdly, existing planning documents and guidelines do not account for biodiversity monitoring and management and could be amended to include biodiversity-related outcomes. We conclude that current New Zealand policies and strategies related to residential developments are inadequate and fail to recognise or encourage the enhancement of urban biodiversity in any meaningful way. Holistic and strategic ecosystem-based approaches are required to protect and enhance urban biodiversity and human wellbeing through the built environment to ensure that biodiversity continues to thrive in New Zealand cities and enrich the lives of urban residents.

Do Consumers Have Colour Aesthetic Preferences for the Facade Materials of Condominium Buildings?

The distinct cultural environment of various regions leads to unique consumer preferences for building facades, including the colours and materials that are used for the exteriors of condominium buildings. Understanding these preferences holds significant industry reference value for urban planning authorities and residential development companies. However, the colour and material aesthetic preferences of consumers for building facades have not received much research attention. To fill this gap, this study empirically investigates these preferences within the cultural context of Fuzhou, China. Using house prices as a reference perspective and econometric methods as research tools, this study explores the specific aesthetic preferences of urban consumer groups and compares the preferences of groups with different levels of consumption. The results confirm the existence of specific consumer preferences for building facade colours and materials and a close connection among the variations in these preferences and various combinations of facade colours and materials. Different quantities and types of materials can lead to distinct preferences for the quantities and features of facade colours. Apart from providing precise professional insights for urban planning authorities and residential developers, this study also offers a feasible conceptual reference for future studies to be conducted in other regions.

Development of a framework to forecast the urban residential building CO2 emission trend and reduction potential to 2060: A case study of Jiangxi province, China

Investigating the CO2 abatement potential of urban residential building from systematic perspective is essential to reach the urban carbon neutrality target. However, previous studies on building CO2 emission trend forecasting were mainly focused on the building operational phase. In this study, a new framework that includes four building stages under a system dynamic model is developed to simulate urban residential building carbon emission changes and the related reduction potentials under three scenarios in Jiangxi Province up to 2060. Results showed that the overall process carbon emission dynamic had already peaked in 2014 under the three scenarios, with a peak value of 38.52 Mt. It then fell to 9.56 Mt in 2060 under the baseline (BAU) scenario. More importantly, seven carbon abatement measures were adopted during four building activities in this study, and the total carbon reduction was not the sum of the carbon reduction potential of the individual measures. Some carbon abatement strategies displayed synergistic effects such as low-carbon electrification where the combination of electrification and clean energy power generation was the largest contributor to reduced carbon emissions during building operation as a comprehensive carbon reduction measure. By contrast, extending a building's lifetime restrained the carbon abatement potential during the demolition stage, and it inhibited the carbon emission reduction by 24.84 Mt. These results highlight the significant need for effective policy interventions for clean production and the need to improve prefabricated building proportions, promote electrification, improve energy efficiency, strengthen recycling practices, and extend building lifetimes to promote decarbonization of urban residential building system development.

Влияние социально-культурных потребностей человека на архитектуру и планировочные решения коливингов

Architectural solutions should always be aimed at meeting the socio-cultural needs of a person. Le Corbusier, Ralph Erskine, Jane Jacobs, Kevin Lynch, Richard Sennett are devoted to the study of the impact of social development on urban planning and residential development. The need for housing to a large extent depends on the period of a person's life. In this regard, Le Corbusier advocated the creation of a flexible architecture that changes depending on the phase of life. Housing should correspond to the social status and personal needs of each family member. One way to fulfill this need is coliving. It is attractive to people at different stages of life. Young people can choose co-living to save on rent and live closer to work and play. Young families can use it to share space with other parents and children. Coliving is also handy during life transitions and allows you to make new friends and have more opportunities for social interaction. Architects who have worked on coliving projects include Olafur Eliasson, Norman Foster, Jeannette Mardini and David Chipperfield. The paper proposes the layout of coliving for housing graduate students and teachers of higher education.

The effect of piping stream channels on dissolved oxygen concentration and ecological health.

Sunlight plays a key role in the nutrient cycle within streams. Streams are often piped to accommodate urban residential or commercial development for buildings, roads, and parking. This results in altered exposure to sunlight, air, and soil, subsequently affecting the growth of aquatic vegetation, reducing reaeration, and thus impairing the water quality and ecological health of streams. While the effects of urbanization on urban streams, including changing flow regimes, stream bank and bed erosion, and degraded water quality, are well understood, the effects of piping streams on dissolved oxygen (DO) concentrations, fish habitats, reaeration, photosynthesis, and respiration rates are not. We addressed this research gap by assessing the effects of stream piping on DO concentrations before and after a 565-m piped section of Stroubles Creek in Blacksburg, VA, for several days during the summer of 2021. Results indicate that the DO level decreased by approximately 18.5% during daylight hours as water flowed through the piped section of the creek. Given the optimum DO level (9.0mg·L-1) for brook trout (Salvelinus sp.), which are native and present in a portion of Stroubles Creek, the resulting DO deficits were - 0.49 and - 1.24mg·L-1, for the inlet and outlet, respectively, indicating a possible adverse impact from piping the stream on trout habitat. Photosynthesis and respiration rates were reduced through the piped section, primarily due to the reduced solar radiation and the resultant reduction in oxygen production from aquatic vegetation; however, the reaeration rate increased. This study can inform watershed restoration efforts, particularly decisions regarding stream daylighting with respect to potential water quality and aquatic habitat benefits.

Assessment of groundwater potential zones for urban development site suitability analysis in Srivaikundam region, Thoothukudi district, South India

To demarcate groundwater potential zones (GWPZ) for the Srivaikundam region in Thoothukudi district, Tamil Nadu, India, an effort was made in this study to locate the subsurface basin for groundwater storage and to identify the suitable destination for the urban development, agricultural, and drinking needs. This study using remote sensing and geographical information system (GIS) with analytical hierarchy process (AHP). According to their respective importance for groundwater occurrence, Saaty's scale was appropriately weighted to give the thematic layers and their attributes. The selected thematic maps were then merged using the weighted linear combination method to produce the final groundwater potential zone map after the layers' assigned weights and their features had been standardized using the Analytic Hierarchy Process (AHP) and eigenvector approach. Based on Saaty's 9-point scale, each criterion or factor was given the proper weight, and the weights were then normalized using the analytic hierarchy approach (AHP). To create the groundwater potential prediction map for the research area, the method was incorporated into the GIS environment. For the purpose of identifying potential urban residential development sites, the generated GWPZ is combined with eight different thematic layers. Groundwater conditions have been used to define GIS analysis criteria, and each information layer has been assigned an appropriate rank and weightage. Finally, groundwater recharge zones have been selected and classified into low, medium, and high based on cumulative weighted value. The moderate groundwater potential zone covers the majority of the land, with areas of very low 0.5 km2 (0.1%), low 112.3 km2 (17.7%), medium 428.7 km2 (67.6%), high 87.8 km2 (13.8%), and very high 5.1 km2 (0.8%) accordingly. Furthermore, higher groundwater yields are estimated in medium to good zones, indicating greater potentiality of groundwater sources.

Performance monitoring of constructed floating wetlands: Treating stormwater runoff during the construction phase of an urban residential development

In the context of climate change and global trend towards greenfield urbanisation, stormwater and transported pollutants are expected to increase, impairing receiving environments. Constructed floating wetlands (CFWs) can improve stormwater retention pond performance. However, performance data are currently largely restricted to mesocosm experiments, limiting design enhancement fit for field implementation. The present 12-month field study aims to fill part of these gaps by identifying limitations and necessary design improvements for CFWs on a large retention pond/lake. Water in a 2.6-ha lake receiving stormwater from a 45-ha urban area under development in subtropical Queensland, Australia, was recirculated during dry weather periods to minimise algal growth and the risks of blooms. Pollutant removal efficiencies of two full-scale CFWs were evaluated during storm events and dry weather periods as a function of inlet and outlet pollutant concentrations, flow and rainfall. Inlet TSS and TN concentrations in runoff during the construction phase of the development exceeded required water quality limits while TP inflow concentrations were low and often below the detection limit. Median pollutant load reduction efficiencies during storm-events were − 20 % TSS, −2 % TN and 22 % TP at CFW1 and 51 % TSS, 3 % TN and 17 % TP at CFW2, respectively. TSS and TN concentration removal efficiencies at CFW1 were low and highly variable, partly due to low inlet concentrations, high flow velocities and short hydraulic retention times (<1 day). However, CFW1 significantly reduced TSS concentrations during dry weather periods. In contrast, CFW2 significantly reduced TSS concentrations during both storm events and during inter-event periods. This study highlights treatment limitations associated to the operational conditions of CFWs at field-scale not identifiable in a mesocosm-scale study. Further research is necessary to investigate treatment performance of CFWs during the operational phase of the development with higher nutrient levels.

What roles do architectural design and on-site water servicing technologies play in the water performance of residential infill?

More than half of new urban residential developments are planned as infill in Australia's major cities. This provides an unprecedented opportunity to use innovative design and technology to address urban water challenges such as flooding, reduced water security and related infrastructure and urban heat island issues. However, infill can have positive or negative water impacts, depending on architectural design and on-site water servicing technologies implemented. In this study we asked, “What influence does residential infill development have on the local urban water cycle?” and “What roles do architectural design and technologies play?” To answer these questions, a set of 196 design-technology configurations were developed by combining 28 architectural designs and 7 on-site water-servicing technology options. The configurations represent three cases: (i) existing (EX) or before infill, (ii) business-as-usual development (BAU), and (iii) alternative development (ALT). Using the Site-scale Urban Water Mass Balance Assessment (SUWMBA) model and a set of water performance indicators, the impact of configurations on the urban water cycle was quantified. The results showed BAU, on average, increases population density, stormwater discharge, and imported water by 98%, 44% and 85%, and decreases evapotranspiration and infiltration by 53% and 34%, compared to the EX conditions. More population density (141%) with lower impacts on the urban water cycle (21% and 64% increase for stormwater discharge and imported water, and 29% and 17% reduction in evapotranspiration and infiltration) can be achieved by appropriate integration of ALT designs and technologies. Architectural design has a greater influence on urban water flows than the implementation of on-site water servicing technologies. The results have a great implication for sustainable urban water management for managing the risks associated with pluvial flooding, water insecurity, and urban heat. It also highlights the underutilised role of architects and urban planners to address urban water issues.

HISTORICAL FORTIFICATIONS IN THE ARCHITECTURAL AND URBAN PLANNING STRUCTURE OF LVIV (ON MARGINES DOCUMENTATION "HISTORICAL AND ARCHITECTURAL REFERENCE PLAN OF LVIV")

Ancient city fortifications are one of the specific types of defensive architecture. Along with the buildings of castles, blocks of urban residential development, monastery complexes and field defensive structures, they formed a special type of architectural and urban planning objects. During their construction, the skills of both an architect, builder, and military engineer were often combined. Not so many objects of urban defense architecture have come down to our time. Therefore, every fragment of the city's defensive walls and earthen fortifications preserved today, as a rule, is a valuable document of its era and needs careful protection and preservation. Urban fortifications (as opposed to fortifications of castles or fortresses) were the objects of priority liquidation in the process of urban development. There are very few of them preserved in Ukraine, so their preservation and study is a matter of extreme importance. Lviv is a unique city on the map of Ukraine in terms of the development of urban fortifications. The article analyzes the reflection of objects and monuments of defense construction in the scientific and design documentation "Historical and Architectural Reference Plan of the City of Lviv". Data on the stages of development of Lviv fortifications are highlighted. Special attention is paid to the remains of fortifications that have been preserved in the archaeological form. Their identification, conservation and identification is important task for modern urban development projects. The paper makes hypotheses about some hitherto unidentified elements of fortifications of the XVII-XVIII centuries. Special emphasis is placed on the need for a special scientific study on the detailed reconstruction of all stages of the development of defense belts around the city center and suburbs of Lviv

Consideration of GREENAREARATIO When Establishing an Urban Development Plan

Purpose: Just as the natural environment is vital for people to live in, the park and green area, which are indicators for eco-friendly development, are essential when proceeding with urban development projects. Therefore, this study reviewed focusing on the park and green area ratio in the environmental impact assessment for urban development projects. Through this, we intended to provide a comprehen-sive guideline for environmental land use planning and design for urban development or residential land development projects and to guide plans and designs based on this. Method: The analysis was based on the environmental impact assessment, which was investigated for 145 urban development projects for 18 years from 2003 to 2020. We conducted a one -way ANOVA analysis to determine the difference between the green area rate by year, the green area rate by region, the population density by region, and the park area per person by region. Post-hoc analysis was per-formed by the Scheffe test. To conduct the above statistical analysis, we used the Spss Statistics 21 sta-tistics program. Results: The number of consultations on environmental impact assessment for urban development projects by year was the highest in 2006 and 2008, with 14 cases(9.66%). The green area rate by year was as high as 25.09% in 2005, 24.88% in 2007, and 22.73% in 2009. The green area rate by region was the highest in the Gangwon area with 22.63%, followed by 20.47% in the metropolitan area, 19.59% in the Honam area, and 19.51% in the Chungcheong area. The population density by region was the high-est with 2.10(person/m2) in the metropolitan area. Next the Gangwon area was 1.99(person/m2) and the Southeast area was 1.80(person/m2). The park area per person by region was the largest in the Honam area, with 10.93m2. Conclusion: The area of parks and green spaces is seen as the minimum standard stipulated by law. However, the high green area ratio and the difference in population density by region during active ur-ban development projects are to create a pleasant residential environment. Therefore, in a place with high population density, it is necessary to establish a high standard for securing green space to create a comfortable living environment. Also, in the case of parks, the location is essential as well as the area. Since green areas on slopes excluding parks in the green area ratio are difficult to use, we insist that green areas on slopes should be reduced, and park areas should be set high to create a pleasant resi-dential environment.

Перспективы развития индустриального строительства жилья

The article discusses modern methods of housing construction and proposes the use of industrial methods of housing construction in Uzbekistan. The most important condition for urban construction is the tight deadlines for the construction of facilities. In urban residential development, apartment buildings erected using prefabricated reinforced concrete structures should prevail. With the growth of urbanization, a steady upward trend in demand for innovative products from precast enterprises is expected. This is evidenced by the experience of many developed countries and the examples discussed in the article.

How Are Urban Green Spaces and Residential Development Related? A Synopsis of Multi-Perspective Analyses for Leipzig, Germany

The relationship between urban green spaces (UGS) and residential development is complex: UGS have positive and negative immediate impacts on residents’ well-being, residential location choice, housing, and land markets. Property owners and real estate agents might consider how prospective clients perceive UGS and act accordingly, while urban planners influence UGS location and management as well as aim at steering the built environment. Typically, studies focus on one of these perspectives at a time. Here, we provide a synopsis of results from studies, taking different perspectives for a single case study: Leipzig, Germany. We summarise and discuss the findings of eight studies on UGS and residential development. In detail, these studies focus on spatial pattern analysis, hedonic pricing analysis, mixed-methods studies on experts’ perspectives, surveys, and choice experiments exploring residents’ perceptions of UGS. We reflect on the feasibility of deriving a synthesis out of these independent studies and to what extent context matters. We conclude that both triangulating of data and methods, as well as long-term and context-sensitive studies are needed to explain the interlinkages between UGS and residential development and their context dependency.

How ecosystems services drive urban growth: Integrating nature-based solutions

Addressing urban challenges with nature-based approaches can improve and protect ecosystem services. Yet, urban planning has not efficiently integrated such approaches to manage land use. This paper examines interactions between human and natural systems that result in ecosystem services and changes in land use and land cover in urban areas. It develops a social-ecological model for land use and land cover change, and for ecosystems services that integrates nature-based solutions in urban planning. The model treats spatial variations in ecosystems services as both drivers and consequences of human decision-making in choosing commercial and residential locations that drive land use and land cover change. We tested the social-ecological model in Stockholm County, Sweden, on a 30 × 30 m grid. Results show that accessibility in ecosystem services drives urban residential and commercial development, characterized by non-linearity. Areas around existing urban centers show high accessibility in ecosystem services and high development probabilities, whereas smaller population centers in large areas enjoy high accessibility to ecosystem services and low urban development probabilities. Model results suggest place-specific nature-based strategies for addressing the heterogeneous spatial relationships between ecosystem services and urban development.

“Social fabric” of the city in the mirror of architecture

The relevance of the selected topic is determined by the fact that the city first and foremost is the center of culture and civilization, which characterizes the development of the surrounding territory and the entire country; secondly, it is the most vivid manifestation of social challenges that modern society is faced to solve. The goal of this research lies in tracing interrelation between the social problems of modern society and the architectural environment of the city. The subject of this article is the modern urban residential development, which is the center of people&amp;rsquo;s everyday life, as well as forms their attitude towards the city and the country overall. The theoretical framework is comprised of the basic provisions of urban studies presented by the Western and Russian authors: F. Braudel, A. Gutnov, G. Simmel, L. Wirth, R. Park, G. Revzin, F. Urban, C. Ellard, and others. The author proves that the development of capitalist relations in the XX century posed a problem of large-scale housing development, which had to meet the two key requirements: a) be affordable for the consumer; b) be profitable for the property developer. Industrialization, unification and typification of construction became the way to solve this task &amp;ndash; the modern urban neighborhood units, slums of industrial and postindustrial era, in which there is neither past nor future alongside social hierarchy and local community united by common goals and values. Having assessed this phenomenon, the author proves that living in such environment aggravates the social, spiritual, and psychological problems of citizens, described by the classics of urban studies. Therefore, the main conflict of modern city is the clash between the economic efficiency of housing development and the aesthetic requirements for the organization of residential environment. This conflict goes beyond the framework of architecture due to the fact that the principles of industrialization, unification, and typification are now universal to all spheres of social life, including culture.

Reliability of the organizational-and-technological model of clusters of sustainable urban residential development

The aim of this study is to determine the interpretation of the term “Cluster of urban residential development” used in the organization of reoriented urban enclaves, taking into account the organizational and technological model of the reliability of formation. In the implementation of such plans, a set of joint tasks of the organizational and technological structure is determined and a number of parameters are taken into account, (comfortable living, with meaningfully used free space; a combination of residential buildings with social, educational, cultural, household and entertainment facilities, etc.), and also - the basic principles of the formation of the reliability of the organizational and technological model of the cluster of urban residential development. The underlying scientific theory is that by using the methods of organizational and technological modeling and system engineering, the indicators of the total durability of construction design can be increased. As a result of the study, the characteristic properties of a cluster of urban residential development were established to be used in an integrated model.

MORPHOTYPES OF RESIDENTIAL DEVELOPMENT IN THE STRUCTURE OF A LARGE CITY

The concepts "morphotype of residential development" and "second home" are defined. Morphotypes of residential development are distinguished by three characteristics: social order, residential unit’s living space per family member, and weighted average time spent on travelling from place of residence to socially most significant areas of the city. Overall, 17 housing morphotypes have been identified, including five types of second housing. The percentage of each type of housing in the total number of residential units in the city is determined. A graph showing growth in the number of garden houses in Penza since the second half of the twentieth century is presented. A diagram of increase in the weighted average number of storeys in residential buildings is provided for some Russian cities. Urban development trends and dependencies in the evolution of the morphological types of urban residential development are revealed, including: permanent growth in living space per family member, globalization and loss of national identity of residential development morphotypes in the late twentieth century, continuing growth in the number of second homes, etc.

A GIS-based approach to explore the factors contributing towards Urban residential land development and re-development (LDR): a case of Rajshahi City Corporation area

ABSTRACT Urban Residential land development and redevelopment intensity (LDR) act as an essential index to understand magnitude of urban livability and sustainable development. Recent urbanization pattern of Rajshahi city has made a rising demand for land, which made it a precious commodity. As a result of it, Rajshahi City Corporation (RCC) area is undergoing significant residential LDR in recent years. The understanding of factors influencing this residential LDR has great importance in real estate development as well as overall housing situation of thecity. For this purpose, this study tries to explore the spatial characteristics of LDR. Relative Operating Characteristics (ROC) test statistics (>0.5) with improve hedonic model are set out to identify the internal drivers of LDR. Finally, geostatistics is explored by integrating methods of Geographic Information System (GIS) and SPSS regression analysis to analyze the correlation between LDR and driving factors. The spatial distribution of residential LDR has shown a strong distance decline law. One of the most exciting findings was that increase in distance to Central Business District (CBD) from the residential land has a slight influence on LDR. The outcomes of the paper will be beneficial for investors and policy-makers in their development decision-making processes.

Offer of solutions on the development of projects of energy-efficient underground multifunctional complexes and public buildings in Ukraine

Problem statement.Today, mankind is faced with the need to solve complex problems related to climate change, emissions of-products of the industrial enterprises into the atmosphere of the planet and as a consequence an increase of the greenhouse effect, man-made disasters, the constant increase of the world population. People need to learn to survive in these difficult conditions and make every effort to prevent in the future the development of negative phenomena. Try to solve these tasks by building energy-efficient underground multifunctional complexes and public buildings (hotels, social and educational institutions, pharmacies, shops, gyms). A long staying under the ground entails a series of transformations of the body: changes in the balance of fluid in the body – within a year, it significantly reduces in the biochemical composition of the human body there will be several new minerals, which are unavoidably inhaled by the person under the ground, vitamin Ddeficiency, hormonal changes, deterioration in psychological state. In the near future, healthy living environments, providing optimal conditions for work, life, leisure and movement of the urban population will depend on the effective use of underground space in urban areas. The purpose of the article is to offer a solution for the development of projects of energy-efficient underground multifunctional complexes and public buildings in Ukraine. Conclusions: energy-efficient underground public buildings solve the problem of construction of high-rise buildings in historically valuable urban residential development, freeing up space above ground for residential buildings and recreational areas as well as conserving natural resources, improving the environmental condition, increasing energy conservation resources in Ukraine.

Energy-Saving Transformation Design of Existing Residential Buildings in Qinba Mountainous Areas

Through investigation, it is found that some existing buildings in Qinba Mountain have high energy consumption and poor indoor thermal comfort. The cost of demolishing and rebuilding is relatively high. Therefore, it is an important issue for the current urban residential development to study suitable local reconstruction strategies. Taking an old community in Hanzhong City of Qinba Mountain as an example, the field test of indoor and outdoor thermal environment in winter and summer was carried out for one house. The current situation of indoor thermal environment in Qinba mountain city buildings in winter and summer was analyzed. The environmental conditions are not ideal. This article uses DesignBuilder software to carry on the comprehensive transformation design to the wall of this existing building, the roof, the outer window and so on, and carries on the simulation analysis to its indoor thermal environment, the result shows that the enclosing structure has a greater influence on the thermal environment of the local building; the transformation model was obtained: 30mm EPS insulation layer was added to the wall, 50mm EPS insulation layer was installed on the roof, and plastic window (6+13A+6) was used as the outer window. After the renovation, the indoor temperature was increased by 11%-21%. This result can provide a certain theoretical reference for the energy-saving reconstruction of the existing residential houses in the Qinba Mountains.
