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.

In the context of the COVID-19 pandemic, inadequate spaces in terms of the dimensions of the environments and lack of flexibility for possible adjustments, not only accentuate health risks, but also interfere in the productivity of remote work and school performance. In this sense, social housing has an unsatisfactory performance in terms of functionality, mainly because they have small spaces and inadequate window frames to achieve satisfactory natural ventilation and reduce the contagion by coronavirus. The objective of this article is to analyze three single-family social housings, aiming to rethink spaces, focusing on some elements necessary to protect the health and well-being of the inhabitants. The method applied concepts of functionality and useful area, in addition to the requirements and criteria of the Brazilian bioclimatic zoning and performance standards, including the construction guidelines for single-family social housings (SH) reflecting on the need to adapt SH to guarantee well-being and inhabitants' health. Analysis results showed that low-income buildings are precarious in terms of functionality and do not allow adaptations due to the architectural design and technical specification of walls and window frames.

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.

PurposeThis study aims to analyze the technical, environmental, economic and thermal comfort impacts of implementing passive measures and heating systems in Ciudad Verde, a large-scale social housing project located at the periphery of Bogota, Colombia.Design/methodology/approachA system dynamics (SD) model is proposed to evaluate scenarios through counterfactual experiments, including technical, environmental and economic components. Model inputs are obtained from building energy simulation models and data collected from official reports, public policy documents and construction records.FindingsResults suggest that the use of heating systems is the best choice to achieve thermal comfort conditions throughout the day. However, both the capital expenditures and CO2 emissions associated with such system make their adoption very difficult. In line with that, the use of heating systems in combination with passive measures stands out as a viable solution since their costs are affordable and their use contributes to reducing CO2 emissions.Originality/valueThe proposed model recreates the dynamics underlying social housing construction processes, the adoption of heating systems and passive measures in low-income dwellings and their corresponding impact on CO2 emissions and indoor thermal comfort conditions. The model can be employed as a support tool in the formulation of social housing policies associated with thermal comfort specifications. In this way, the model represents a first step toward incorporating thermal-related variables into the decision-making processes related to social housing planning and development.

Developing nations face increasing economic and environmental challenges and the search for housing design solutions that approach sustainability by meeting thermal comfort, energy efficiency, environmental and low initial cost criteria is underway. This paper presents the results of a multidisciplinary research project that aimed at designing a low-income house and a middle-income house that perform well from the architectural, thermal comfort, and energy efficiency standpoint while being cost-competitive. Multiple passive cooling strategies were considered and evaluated by energy modeling tools. The thermal and energy performance of the proposed designs were analyzed throughout the design process and the various design iterations. A full budget was prepared for the proposed low-income housing design and first-costs were found to be competitive with conventional housing. The paper discusses the proposed design features, their impact on thermal comfort and energy efficiency and the feasibility of integrating alternative energy systems to the proposed designs.

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.

Abstract Natural ventilation was analysed in a low-income dwelling to control open or closed windows according to a dynamic simulation process in sub-humid warm climate. A selective algorithm to control natural ventilation was determined in an annual period per hour with the following findings: a) an algorithm to select open or closed windows was determined, b) comfort hours per year were evidenced with open, closed windows and selective algorithm to operate natural ventilation, and c) the schedule and periods of ventilation control were presented. Meteonorm® data were used on an hourly basis in Design Builder® simulations and the Meteorological System data based on 30 years of measurements were used to determine the comfort range. Conclusions: the potential benefits to be obtained by applying this ventilation strategy with a selective algorithm are observed in sub-humid warm climate.

Design And Construction

The development of social housing In Mexico during the last decade has been supported by the different levels of government (federal, state, and municipal) in order to assist low-income families. The accelerated construction that takes place in order to address the housing deficit causes a reduction in the quality of design and construction, which is also affected by rising building costs. Environmental comfort conditions inside the dwellings are reduced drastically when houses are constructed without considering climate conditions, especially in hot arid regions. This situation generates uncomfortable thermal conditions for users and high-energy costs due to the unavoidable need of air conditioning. User profiles, architectural program, comfort preferences and guidelines for design and construction of future dwellings in the city of Hermosillo, in northwest Mexico, were determined by surveying beneficiaries of government affordable housing programs. One survey measured the degree of satisfaction of inhabitants in a sample of over 370 households; a second survey sampled 200 households and was aimed at determining aspects of comfort. This paper describes the results of thermal simulations carried out on two housing models. The first model represents the type usually constructed by commercial developers, and the second is a proposal developed by the research team according to guidelines based on the results of the research project described before. This study is a preliminary step in the construction of a physical model for experimental research and demonstration.

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.

Global endeavors to respond to the problems caused by climate change and are leading to higher temperatures inside homes, which can cause skin conditions (such as eczema), lethargy, and poor concentration; disturbed sleep and fatigue are also rising. The energy performance of buildings is influenced by interactions and associations of numerous different variables, such as the envelope specifications as well as the design, technologies, apparatuses, and occupant behaviours. This paper introduces simple and sustainable strategies that are not dependent on expensive or sophisticated technologies, as they rely only on the actions practiced by the building’s occupants (movable window shading, and nighttime natural ventilation) instead of completely relying on high-cost mechanical cooling systems in buildings located in the main Eastern Mediterranean climates represented in the country of Jordan. These low-energy solutions could be applied to low-income houses in hot areas to avoid health problems, such as dermatological diseases, and save a significant amount of energy. The final results indicate that window shading has significant potential in reducing the cooling load in different climate zones. Natural ventilation exhibits high energy-saving abilities in climates that have cool nights, whereas its abilities in hot climates where nights are moderate is limited.
