Design Drivers for Affordable and Sustainable Housing in Developing Countries

Current demand for housing worldwide has reached unprecedented levels due to factors such as human population growth, natural disasters and conflict. This is felt no more so than in developing countries which have experienced disproportionate levels of demand due to their innate vulnerability. Many current approaches to housing delivery in developing countries continue to utilize inappropriate construction methods and implementation procedures that are often problematic and unsustainable. As such affordability and sustainability are now vital considerations in the international development debate for housing the poor in developing countries in order to meet the long term sustainable development goals and needs of housing inhabitants. This paper utilized an extensive scoping study to examine the various facets impacting on design decision making relative to sustainable and affordable housing delivery in developing country contexts. Aspects of affordability, sustainability, design decision making, appropriate technology use, cultural awareness, as well as current barriers to affordable and sustainable construction in developing countries are examined in detail. Results highlighted the capability of indigenous knowledge, skills and materials as well as selected appropriate technology transfer and cultural awareness by foreign bodies can be utilized in innovative ways in addressing current housing needs in many developing country contexts.

IN PRAISE OF SHARING AS A STRATEGY FOR SUSTAINABLE HOUSING

A central theoretical principle of sustainability is the interdependence of economic,socio-cultural,environmental,and equity issues.The core idea is that sustainability is achieved only by balancing these elements.In practice,however,this balance is rarely evidenced in the design and production of housing,despite the mass of research into sustainable housing.This paper discusses some of the political,economic and socio-cultural issues at work in sustainable housing typologies.It illustrates how the notion of sustainability has come to be represented by ecologically-focused models,while other approaches to sustainable housing design,such as shared housing models,are barely mentioned in the literature.The paper argues that modernist imperatives,such as demands for speed and status undermine sustainable housing design and obscure its meaning.The authors suggest that in the planning and design of sustainable housing attention should be given to the sharing of resources and space as an added method of conservation,and conclude that current imbalances in research agendas and socio-cultural practices create a blind spot in the sustainable housing debate.

The Influence of Displacement to the Success of Sustainable Multi-Storey Housing Development for Low-Income Society in Urban Area： Case Study- Multi-Storey Housing in Jakarta

Multi-storey housing for low income society is a concept of redevelopment from many alternatives of housing development for slum in Jakarta. However, redevelopment directly or indirectly leads to displacement of low-income residents. The new residents would be of a higher socio-economic status than the previous occupants. For controlling this phenomenon, a study about the influence of displacement to the successful of sustainable multi-storey housing development for low-income society has been done with descriptive method, observation and literature study. The result of this study give knowledge that displacement always happened when the quality of building and environment is increase, the location of multi-storey housing is near city center and commercial area. Low income society voluntary displaced their units to middle or high income society, because they are not affordable for paying operational and maintenance costs. The government has to make regulations for controlling displacement on multi-storey housing for low-income society and for the successful of sustainable multi-storey housing development in urban area.

The Benefits of Solar Energy on the Provision of Sustainable Affordable Housing in Nigeria

Solar energy is the most abundant form of energy on Earth. Solar energy brings impactful benefits and products that are expected to make homes more reliable, sustainable, and affordable. Thanks to technological advancements like the solar cell, we can gather this energy and turn it into electricity. The construction industry has an exceptional chance of benefiting from this sustainable energy. Many recognised benefits have been spelled forth in the construction industry, such as providing homes with clean energy with no trace of ozone depleting material emission. There are many people in Nigeria who are not linked to the public electric grid, and the energy sector produces and generates less than 58% of the entire amount of energy required. As stated in the Nigeria’s National Energy General Plan, the Sustainable Energy programme aims to enhance the country’s use of solar electricity. This paper focuses on the role of solar energy in the provision of sustainable affordable housing in Nigeria. It considers the description, method, and utilisation of solar energy with a focus on residential and commercial buildings.

LOW-ENERGY DESIGN METHODS AND ITS IMPLEMENTATION IN ARCHITECTURAL PRACTICE: STRATEGIES FOR ENERGY-EFFICIENT HOUSING OF VARIOUS DENSITIES IN TEMPERATE CLIMATES

With mounting concerns over climate change and urban population growth,the demand for sustainable housing based on low-energy designs is steadily increasing.A variety of low-energy design methods have been developed to reduce energy and resource consumption;however,research shows that the implementation of such methods has been surprisingly limited.In addition,while the degree of housing density is understood to have an impact on low-energy designs,what that impact is and how it can be strategically applied have not been adequately researched.This research examines how low-energy designs are applied in housing types with various densities in temperate climates,identifies the issues and problems pertaining to the implementation of passive and active design strategies.This research uses a survey,which asks design practitioners to rate the merits of various low-energy design strategies and assesses how often these approaches are implemented in practice.The study uncovers discrepancies between perceived importance of low-energy design aspects and their practical implementation,finding that certain low-energy strategies can be more effective when they are incorporated in an early stage of the design process.

DESIGN CONCEPTS FOR THE INTEGRATION OF BAMBOO IN CONTEMPORARY VERNACULAR ARCHITECTURE

This paper discusses the development of design concepts for a row of typical bamboo houses,including the layout configuration and the function/aesthetics properties that are important from an architectural perspective.The purpose of this paper is to discuss the role of bamboo in investigations of structural and sustainability benefits and to highlight key research ideas that are important for industrialized production and cultural systems.The development of bamboo housing systems can advance efforts directed at securing home ownership for low-income families through lowering the construction costs to levels that are within their budgets.This paper aims to demonstrate approaches for using bamboo as a structural material for low-income and affordable housing.Bamboo housing can improve the financial stability and economic sustainability of low-income families.This paper presents a review of examples of vernacular architecture and building elements and then highlights the design of two bamboo-structure residential houses based on bio-climatic design strategies.
