Abstract: Affordable housing has long been one of the basic necessities of life to man. The ever rising prices of building materials are one of the major causes of housing shortage in many developing countries. Breaching the gap of housing needs in developing countries like Nigeria is an awaiting task longing for attention. This is due to lack of research in the development of local materials that will suit the troubled economies of these countries. The use of earth material to meet the housing needs is a sustainable option and its material is freely available universally. However, people are doubtful of using the earth material due to its modest outlook and uncertain durability. This research aims at enhancing the durability of Compressed Earth Bricks (CEBs) using stone dust as a stabilizer. The result indicates that partial replacement of lateritic soil with stone dust at 30% improves its compressive strength along with abrasive resistance.
Abstract: The growing cities of the developing country are characterized by rapid growth and poor infrastructure management inviting and accelerating relative environmental problems. Even though the movements of the sustainability had already been developed around the world, it is still increasing in the developing countries to plant sustainable practices. Aligned with the sustainable development actions, many sustainable assessment tools are also developed to rate and evaluate the sustainability performances through the building to community level. Among them, CASBEE is developed by Japanese organizations and is recognized as one of the international well-known assessment tools. The main purpose of the study is to find out the potential of CASBEE tool reflecting sustainability city level performances in developing countries. The research framework was designed with three major phases: Quantitative Approach, Qualitative Approach and Evaluation Reflection. The first two approaches were based on the investigation of tool’s contents and indicators by means of three sustainable dimensions and sustainability categories. To know the reality and reflection on developing country, Pathein City from Myanmar was selected and evaluated by 2012 version of CASBEE for Cities. The evaluation practices went through assigned indicators and the evaluation outcome presents the performances of Pathein city’s environmental efficiency as a very good in current conditions. The results of this study indicate that the indicators of this tool have balance coverage among three dimensions of sustainability but it has not yet counted enough for some indicators like location, infrastructure and institution which are relative to society dimension. In the developing countries’ cities, the most critical issues on development such as affordable housing and heritage preservation which are already planted in Pathein City but the tool does not account for those issues. Moreover, in some of the indicators, the benchmark and the weighting coefficient are strongly linked to the system birth region. By means of this study, it can be stated that CASBEE for Cities would be potential for delivering sustainable city level development in developing country especially in Myanmar along with further inclusion of the indicators.
Abstract: In order to solve the housing problem for the low-income families, the construction of affordable housing is booming in China. However, due to various reasons, the service facilities and systems in the indemnificatory residential community meet many problems. This article established a Satisfaction Evaluation System of the Fundamental Public Services for Large-scale Indemnificatory Residential Community based on the national standards and local criteria and developed evaluation methods and processes. At last, in the case of Huagang project in Nanjing, the satisfaction of basic public service is calculated according to a survey of local residents.
Abstract: The overall goal of this paper is to examine the
suitability and potential of the policies addressing the sustainability
and affordability of housing for returnees, and to determine the impact
of this policy on housing delivery for Afghan refugees. Housing is a
central component of the settlement experience of refugees. A positive
housing situation can facilitate many aspects of integration.
Unaffordable, and unsafe housing, however, can cause disruptions in
the entire settlement process. This paper aims to identify a suite of
built forms for housing that is both affordable and environmentally
sustainable for Afghan refugees. The result was the development of a
framework that enables the assessment of the overall performance of
various types of housing development in all zones of the country.
There is very little evidence that the present approach of housing
provision to the vagaries of market forces has provided affordable
housing, especially for Afghan refugees. There is a need to incorporate
social housing into the policy to assist people who cannot afford to
have their own houses.
Abstract: Affordable housing delivery for low and lower middle income families is a prominent problem in many developing countries; governments alone are unable to address this challenge due to diverse financial and regulatory constraints, and the private sector's contribution is rare and assists only middle-income households even when institutional and legal reforms are conducted to persuade it to go down market. Also, the market-enabling policy measures advocated by the World Bank since the early nineties have been strongly criticized and proven to be inappropriate to developing country contexts, where it is highly unlikely that the formal private sector can reach low income population. In addition to governments and private developers, affordable housing delivery systems involve an intricate network of relationships between a diverse range of actors. Collaboration between them was proven to be vital, and hence, an approach towards partnership schemes for affordable housing delivery has emerged. The basic premise of this paper is that addressing housing affordability challenges in Egypt demands direct public support, as markets and market actors alone would never succeed in delivering decent affordable housing to low and lower middle income groups. It argues that this support would ideally be through local level partnership schemes, with a leading decentralized local government role, and partners being identified according to specific local conditions. It attempts to identify major attributes that would ensure the fulfillment of the goals of such schemes in the Egyptian context. This is based upon evidence from diversified worldwide experiences, in addition to the main outcomes of a questionnaire that was conducted to specialists and chief actors in the field.
Abstract: The concept of housing affordability is a contested
issue, but a pressing and widespread problem for many countries.
Simple ratio measures based on housing expenditure and income are
habitually used to defined and assess housing affordability. However,
conceptualising and measuring affordability in this manner focuses
only on financial attributes and fails to deal with wider issues such as
housing quality, location and access to services and facilities.
The research is based on the notion that the housing affordability
problem encompasses more than the financial costs of housing and a
households ability to meet such costs and must address larger issues
such as social and environmental sustainability and the welfare of
households. Therefore, the need arises for a broad and more
encompassing set of attributes by which housing affordability can be
assessed. This paper presents a system of criteria by which the
affordability of different housing locations could be assessed in a
comprehensive and sustainable manner. Moreover, the paper explores
the way in which such criteria could be measured.
Abstract: This work presents a low-cost and eco-friendly
building material named Agrostone panel. Africa-s urban population
is growing at an annual rate of 2.8% and 62% of its population will
live in urban areas by 2050. As a consequence, many of the least
urbanized and least developed African countries- will face serious
challenges in providing affordable housing to the urban dwellers.
Since the cost of building materials accounts for the largest
proportion of the overall construction cost, innovating low-cost
building material is vital. Agrostone panel is used in housing projects
in Ethiopia. It uses raw materials of agricultural/industrial wastes
and/or natural minerals as a filler, magnesium-based chemicals as a
binder and fiberglass as reinforcement. Agrostone panel reduces the
cost of wall construction by 50% compared with the conventional
building materials. The pros and cons of Agrostone panel as well as
the use of other waste materials as a raw material to make the panel
more sustainable, low-cost and better properties are discussed.
Abstract: The right to housing is a basic need while good
quality and affordable housing is a reflection of a high quality of life.
However, housing remains a major problem for most, especially for
the bottom billions. Satisfaction on housing and neighbourhood
conditions are one of the important indicators that reflect quality of
life. These indicators are also important in the process of evaluating
housing policy with the objective to increase the quality of housing
and neighbourhood. The research method is purely based on a
quantitative method, using a survey. The findings show that housing
purchasing trend in urban Malaysia is determined by demographic
profiles, mainly by education level, age, gender and income. The
period of housing ownership also influenced the socio-cultural
interactions and satisfaction of house owners with their
neighbourhoods. The findings also show that the main concerns for
house buyers in urban areas are price and location of the house.
Respondents feel that houses in urban Malaysia is too expensive and
beyond their affordability. Location of houses and distance from
work place are also regarded as the main concern. However,
respondents are fairly satisfied with religious and socio-cultural
facilities in the housing areas and most importantly not many regard
ethnicity as an issue in their decision-making, when buying a house.
Abstract: Reasonably priced and well-constructed housing must
be an integral and element supporting a healthy society. The absence
of housing everyone in society can afford negatively affects the
people's health, education, ability to get jobs, develop their
community. Without access to decent housing, economic
development, integration of immigrants and inclusiveness, the society
is negatively impacted. Canada has a sterling record in creating
housing compared to many other nations around the globe. Canadian
housing gets support from a mature and responsive mortgage network
and a top-quality construction industry as well as safe and excellent
quality building materials that are readily available. Yet 1.7 million
Canadian households occupy substandard abodes. During the past
hundred years, Canada's government has made a wide variety of
attempts to provide decent residential facilities every Canadian can
afford. Despite these laudable efforts, today Canada is left with
housing that is inadequate for many Canadians. People who own their
housing are given all kinds of privileges and perks, while people with
relatively low incomes who rent their apartments or houses are
discriminated against.
To help solve these problems, zoning that is based on an
"inclusionary" philosophy is tool developed to help provide people
the affordable residences that they need. No, thirty years after its
introduction, this type of zoning has been shown effective in helping
build and provide Canadians with a houses or apartments they can
afford to pay for. Using this form of zoning can have different results
+depending on where and how it is used. After examining Canadian
affordable housing and four American cases where this type of
zoning was enforced in the USA, this makes various
recommendations for expanding Canadians' access to housing they
can afford.
Abstract: A large section of the society in Urban India is unable
to afford a basic dwelling unit. Housing shortage due to the rising unafforability makes it logical to consider alternative technologies more seriously for their application How far do these alternative
technologies match up with the conventional techniques? How do these integrate with the present-day need for urban amenities and
facilities? Are the owners of bamboo dwellings, for instance, a part of
the mainstream housing sector, having the same rights and privileges
as those enjoyed by other property owners? Will they have access to loans for building, improving, renovating or repairing their
dwellings? Why do we still hesitate to build a bamboo house for ourselves? Is our policy framework and political resolve in place, to
welcome such alternative technologies? It is time we found these answers, in order to explore the reasons for large-scale nonacceptance,
of a technology proven for its worthiness.
