Abstract Housing sector plays an essential role in the sustainable development of the countries; however, there are significant problems in terms of its ability to access which promotes the occurrence of solutions that guide the housing deficit reduction as well as economic savings and natural resources preservation. One key strategic would be the use of social housing as a mechanism to ensure a decent house accessed by vulnerable population. The general housing design requires satisfying characteristics of indoor environmental comfort, arising the need outlook technical solutions. This research aims to propose functional and hygrothermal improvements for social housing located in a temperate continental climate zone in The Sierra region of Ecuador. The methodology was focused on energy simulations using Design Builder software and comparing the results with the application of passive bioclimatic recommendations. In addition, based on the quantitative housing deficit this research achieves qualitative contributions in order to improve the living conditions of low-income population whose get access to social housing in Ecuador. An experimental case study, located in Azogues a canton of the province of Cañar, has been selected for the simulation analysis which belongs to a housing governmental program named Manuela Espejo promoted by the Ministry of Urban Development and Housing and special designed for people with disabilities. The research has an applicative nature approach, with a sectional scope and explanatory depth, based on primary and secondary information sources; data collection techniques were social perception surveys used to determine comfort levels of the social housing users. The results show, based on the energy simulations carried out, improvements in terms of habitability conditions and an architectural proposal compiles passive bioclimatic recommendations focused on the design of social housing in Ecuador. Therefore, this research contributes to the implementation of new social housing plans that not only would help to reduce the housing deficit, but also contribute to improving the housing indoor environmental comfort perceived by the users.

Abstract Brazil's current housing deficit exceeds 6 million homes and a demand of 10 million homes for low-income families is expected by 2040. On the other hand, during the last 10 years, approximately 850,000 social housing units have been delivered through the "My House, My Life" Program - (Programa Minha Casa, Minha Vida - PMCMV). Despite these numbers, several studies suggest some problems related to the low quality of the houses. This article aims to investigate the design parameter related to the geometry of social housing in Chapecó/SC, Brazil, which contributes to the achievement of the best thermal performance. Parametric methods and multi-objective optimizations were utilized, two objective-functions were optimized regarding the degree-hours for cooling and heating. The results showed significant improvements, reaching up to 98% during the hot period and 49% during the cold period. Guidelines were defined to assist architects in the early-phases of the social housing design based on the climate of the target region. However, the best design solutions for thermal comfort throughout the year can only be indicated with computational methods.

The Impact

Energy consumption in the social housing sector constitutes a major economic, social, and environmental issue, because in some countries such as France, social housing accounts for about 19% of the housing sector. In addition, this sector suffers from ageing, which results in high energy consumption, deterioration in the occupant quality of life, and high pressure on the budget of low-income occupants. The reduction of the energy consumption in this sector becomes a “must”. This reduction can be achieved through energy renovation and innovation in both energy management and occupant involvement by using smart technology. This paper presents a contribution to this goal through the investigation of the impact of smart monitoring on energy savings. The research is based on monitoring of comfort conditions in an occupied social housing residence in the North of France and the use of building thermal numerical modeling. Results of monitoring show that the indoor temperature largely exceeds the regulations requirements and the use of a smart system together with occupant involvement could lead to significant savings in heating energy consumption. The novelty in this paper concerns the use of comfort data from occupied social housing residence, occupation conditions, and building thermal modeling to estimate energy savings. The proposed methodology could be easily implemented to estimate heating energy savings in social housing buildings that lack individual energy consumption monitoring.

The Subject

The subject of the study is the organizational and economic aspects of managing the equilibrium state of housing affordability for the population during construction. The analysis shows that despite the successful development of the housing sector and the functioning of the housing market, housing affordability is differentiated, which is manifested in unsatisfactory housing conditions of a significant part of low-income and other established categories of citizens. The aim of the study is to improve the processes of ensuring targeted consistent housing policies already at the construction stage to increase not only market, but also social affordability of housing. Materials and methods include a methodological approach, which involves the construction of a model of interaction between the investor and local authorities during the construction process in order to accelerate the solution of the problem of increasing housing affordability for the low-income citizens on the basis of ensuring the required volumes of housing construction in accordance with the main legislative formats. The optimization of the coordination model of the interests of investors and the municipality during the construction in this social housing cluster is ensured through the implementation of mechanisms to reduce the expenses of investors to obtain a land plot, as well as the proposed measures that increase the social accessibility of housing. The task is to ensure the balance and comprehensiveness of the market and social affordability of housing for various categories of citizens by expanding the list of powers of municipalities and financing their implementation for the construction of social housing facilities.

AbstractSpace Syntax researchers have asserted that the spatial configuration of the planning of a work of architecture, such as a house, reflects how social properties are inscribed in its design. In social housing, the social inscriptions through space, which promote a particular way of dwelling, are not initially determined by the inhabitants. However, through appropriation, inhabitants mold the space to their liking, challenging preconceived ways of dwelling. Therefore, this research aims to determine what kinds of social structures the spatial configuration of social housing are promoting and how the inhabitants' transformations have altered the spatial experience. Mexico's housing sector developed from a “welfare approach” in the nineteen seventies and eighties to a “market rationale” since the nineties. During this time, different dwelling perspectives were inscribed in the spatial configuration of the homes. Using the justified plan graph (JPG) method, six social housing dwellings from these two time periods, Welfare State and market rationale, are spatially analyzed, both in their original design and in the resulting design from their inhabitant's modifications. Graph analysis is used in this paper for providing spatial insights into social housing design and its users' transformations, while pointing to further research needs.

Nghiên cứu được thực hiện nhằm đánh giá thực trạng phát triển nhà ở xã hội (NOXH) cho người có thu nhập thấp (TNT) tại một số đô thị trên địa bàn tỉnh Bình Định trên cơ sở thu thập số liệu từ các phòng ban chức năng và khảo sát thực địa. Kết quả nghiên cứu cho thấy phát triển NOXH tại tỉnh Bình Định đã giải quyết vấn đề về nhà ở cho 1.876 hộ TNT trong giai đoạn 2009-2019. Nguồn cung về NOXH cho người có TNT có sự thay đổi tích cực: giai đoạn 2018-2020 tăng gấp 12,55 lần so với giai đoạn 2009-2017. Các dự án NOXH cho người có TNT tập trung chủ yếu ở thành phố Quy Nhơn cho thấy sự đầu tư có trọng điểm, có thứ tự ưu tiên. Tỉnh đã huy động được các doanh nghiệp tư nhân tham gia đầu tư xây dựng NOXH cho người TNT. Tuy nhiên, nhiều dự án NOXH cho người có TNT chậm tiến độ hoặc không triển khai, chưa tiếp cận đúng người TNT có nhu cầu nhà ở, tình trạng sang nhượng NOXH không đúng quy định, chất lượng một số công trình chưa đảm bảo và công tác quản lý NOXH chưa đạt hiệu quả mong muốn. Trong nghiên cứu cũng đề xuất được một số giải pháp nhằm tăng hiệu quả tiếp cận NOXH cho người có TNT tại Bình Định. ABSTRACT This study was conducted to assess the status of social housing development for low-income people in some urban areas in Binh Dinh province based on data collection from functional departments and survey results. Research results showed that the development of social housing for low-income people in Quy Nhon city, An Nhon town and Bong Son town in Binh Dinh province has provided 1,760 apartments for people with low income in the period of 2009 - 2019. In this period, 10 housing projects for low-income people were implemented in the study area, of which 05 projects were launched for sale and 05 projects were delayed. The supply of social housing for low-income people has not met the targets, the management and development of social housing for low-income people in the study area is not strict. According to the social housing development plan, the total social housing supply will be 3.966 units in 2020 and 4.900.550 units in the period of 2021 - 2025. The study has proposed four solutions to increase the effectiveness of social housing development for low-income people in Binh Dinh.

Large migration from rural areas to urban areas like Kuala Lumpur has led to some implications for economic, social and cultural development. This high population has placed enormous demand on the existing housing stocks, especially for low-income groups.  However, some issues arise, one of which is overheated indoor air temperature. This problem contributes to the high-energy usage that forces huge sums of money to be spent on cooling the house by using mechanical equipment. Therefore, this study focuses on thermal comfort in social housing, and incorporates traditional values into its design to achieve a certain measurement of natural ventilation in a house. From the study, the carbon emission and energy consumption for an air-conditioned house is 67%, 66% higher than a naturally ventilated house. Therefore, this research has come up with a new typology design, which has a large exposed wall area and full-length openings on the opposite walls to increase cross ventilation. At the end of this research, the measurement of thermal comfort for a naturally ventilated building called ‘Air House’ has been identified.

Abstract In the developing world, practical steps are taken to provide adequate, sustainable housing, especially for low-income people within technological age capabilities in construction by searching for new techniques of building technology to meet that goal. In the Arab countries, contemporary housing design is particularly effective because it is the primary unit of the contemporary urban fabric and the basic cell that constitutes most of the city’s area. So the following research questions are discussed in this study: What are the challenges facing contemporary sustainable housing design in specific affordable housing for the lower-income groups? What is the potential for sustainable building technology to meet that goal considering the social and economic dimension of the COVID 19 pandemic? What are the ambitions that they set out to achieve in that house? To emphasize the essential role of sustainable building technology and techniques in acquiring and implementing different goals and actual needs of all strata of society.

Early Stage Design

Participation has been touted as a critical instrument for both citizen empowerment and responsibility-sharing in sustainability. In architecture, participation allows for the progression of green building to sustainable habitation that integrates environmental, economic, and social dimensions. However, participation in practice rarely delegates meaningful decisions to marginalized groups and is mostly a one-sided process. This study seeks to investigate which factors of the participatory method afford both empowerment and behavioral change to a sustainable lifestyle in low-income groups. To do so, a case study of designing a social housing estate in Hungary is presented, where participatory design was used to codevelop a building that considers and adjusts to the sustainable lifestyle envisioned by the future residents. A coding engine based on the concept of pattern languages was developed that places conditions and experience of everyday activities at the center of design, translating them to spatial features. As a result, a focus group of social housing tenants and cohousing experts were able to define explicit shared spaces, allocate square meters to them, and articulate legible design criteria. Of the early-stage design decisions, 45% were made with or by the participants, and the bilateral process made it possible to convince the tenants to adopt a more sustainable habitation format.

In India the housing shortage is much severe with an estimated shortage of around 18 million houses, with 99% of this is in the economically weaker sections of society. Social housing is the housing system provided for people with low income by government agencies or non-profit organizations. This research paper is about the study of the methods of construction that is adopted in social housing system which will help in improving the social deficit in the housing sector. The study is done with the help of live case studies on housing projects in and around Hyderabad which comes under the flagship programme JNNURM for economically weaker section. The study concluded that the contemporary methods of construction is considered to be advantageous as the government does not provide enough funds for the housing projects and also the contractors are not willing to take any risk and pay for any other modern method of construction.
