| Summary: | The housing industry in Malaysia is regarded as one of the major industries contributing to
the economic and socio development of the country. Housing is a major concern for all people
in every corner ofthe world as the wellbeing of a country is reflected in its people enjoying a
certain standard of living. This research work aims at investigating and identifying the
abandoned low cost houses in Sarawak, with special reference to a number of areas e.g.
1
Kuching, Kota Samarahan and Betong. Abandoned house can be define as property legally
./
unoccupied for at least six months and fulfil one of the number of the criteria, such as being in
need of rehabilitation. The completed housing that has been abandoned may allow third
parties to get rid of their waste materials in an illegal manner. In many situations an additional
risk may be imposed by structural disintegration of the building over the years. This may lead
to a direct danger that part of the structure could come down. Abandoned houses also do
indeed have a negative impact on the value of houses in close proximity. According to our
findings, there are a lot of factors contributed to low cost housing abandonment in Sarawak
but for the purpose ofthis research we selected two ofthem i.e. materials and design.
This research work was divided into two parts; the fll"St data collected were analysed using
SPSS statistical software where the researcher found the respondents view about their
residential area and the level of their comfort within the area. The second part of this research
work was presentation of a study on different types of roofmg materials and construction
using Energy Plus®, software simulation for thermal comfort in Sarawak Houses. Energy
Plus® is a building simulation program for modelling building heating, cooling, lighting,
ventilation and other energy flows. It is being developed by the government base on its
predecessors, BLAST and DOE-2 and has undergone extensive testing to ensure that the
internal models are reliable. Energy Plus® uses text based inputs and outputs which make it
ii
easier to analyse the data. Development of science and technology changes man's attitude
towards life, which in turns was manifested his house design as well. Materials and tradition
were became little significant as well as climatic design which almost neglected. The research
work at the end give suggestions and recommendation to the Government and Developers the
suitable Materials and design which will fulfil all the requirement of Sarawak climate for
thermal comfort. Lightweight materials such as hollow block, veneer/ fibre-clad, cavity wall,
lightweight concrete, zinc etc were recommended to be use for wall and roofing construction
since they have low heat storing and there won't be much heat radiation towards the inner
side of the building. Also materials such as concrete and bricks when use for construction,
were suggested to be insulated from the outside since the absorbed large amount of heat, this
heat is then released when the air becomes cooler. |
