Abstract
The
purpose of this research is to develop a new affordable and sustainable green
home which focusing on affordability of young generation to have their own
house in early age of working. When housing affordability is measured by
rent-income ratios based on annual income, affordability must be correlated
with income. Moreover, housing will appear to be less affordable for the very
young and very old; it will appear to be more affordable to households at the
peak of their lifetime income profiles (Quigley J.M & Raphael. S (2004).
This
research then appraises the costing of materials for commercial housing
development as possible avenue for cost reduction in the house price. Another
element is the management of materials at construction site. It is hoped that
out of this research a Commercially Affordable Sustainable House (CASH) module
could be developed and later implemented for meeting the country’s housing
needs and becoming an environmentally responsible country at the same time.
Framework
The
observation, interviews and survey is used in the collecting data method. Data
mining with individual and group interviews in this research are considered as
a convenient way to collect data. This method allows each person to respond to
question, then asking questions, exchanging comments according to his/her
experiences and points of view. The interviews and survey used the form of
questionnaire. In this research exploring existing cost data is needed to
formulate financial for Housing construction. Thus, the approval and the
collaboration with local authority is very important.
The
first part of this research is to collect data regarding to the critical
construction process in housing project management and factors influencing the
house price in Langat District. The survey will used to collect data on house
price and household income to get the price to income ratio, this data mining
will involve INSPEN, MHLA and stakeholder, Second part of the collecting data
method is using interview to define categories of factors with the developers
and CIDB. By using this technique, the researcher could identify the main
aspects, categories, indicators, and parameters to develop simulation on
costing of construction for affordable sustainable housing scheme and housing
price index for the university township.
Second
part of this research is to identifying factors to reduce cost by analyze
unnecessary content or over specification from the housing project and propose
a framework provides a suitable checklist for the cost management of CASH（commercial
affordable sustainable house） in both formal
and informal housing sector of the economy.
One
of this work aims to present a mathematical programming approach to solve
imprecise housing cost problems with fuzzy goal and fuzzy cost coefficients. It
will designed to minimize total project costs with reference to direct costs,
indirect costs, contractual penalty costs, duration of activities and the
constraint of available budget. Few models for costing and housing analysis
such as hedonic models,
fuzzy programming will be use to develop CASH.
Third
part of this research is to identify the best system and design of rainwater
harvesting-system by using literature review method. This stage will explore
the existing house and proposes house design that is suitable for incorporating
in rainwater-harvesting system. Towards the end, with the integrated an
architect, QS, Property Finance, Finance, BS, GBI, Project Management, this
research will identifying new construction and material system, new management
tool, new system of unburden CASH and factors to reduce overall cost for CASH.
Conclusion
The
concern of this research is to design towards the development of critical
construction processes in housing
project management for developing affordable and sustainable housing scheme. it
is well known in
Malaysia the difficulty in ownership of housing especially for middle income
category. Thus, this research
is useful to help housing construction in determining which element that can
help in reducing the price
of new houses. Furthermore, green element if beeing
introduce, may give significant effect in long run
of life span and life cycle of the building. Researcher of this group will try
to formulate the best solution
in order to help middle income buyers for nation development.
