dc.description.abstract |
All over the world, sustainability has been given immense attention, thus novel stateof-the-art
materials and building systems are emerging as alternatives. With those
different alternatives, comparison and the selection of a better-performing material or
a building system using diverse perspectives such as economic, ecological, social, and
cultural are important to ensure the adaptation of the proposed research findings to the
particular community. Even though many researchers introduced multiple material
selection frameworks using economic and ecological parameters, a holistic approach
including Social and Cultural adaptability of those selections has been overlooked in
previous studies.
This study proposed an eco-design-based material selection approach that considers
the individual and wholistic perspective of diverse themes including economic,
ecological, social, and cultural. Several sub-themes are identified under each theme
and are verified through expert surveys. The pairwise comparison of themes and subthemes
and
analysis
using
the
Analytical
Hierarchy
Process
(AHP)
leads
to
proposing
weights
for
each
theme
and
sub-theme
and
developing
an
eco-design-based
material
selection
framework in ranking and choosing better-performing building materials.
Accordingly, saving energy, reducing the overexploitation of natural resources,
reducing energy emissions, and reducing construction, as well as operational cost, are
the parameters that create a greater impact on the selection of sustainable material with
the aid of eco-design.
Furthermore, the developed framework is validated by comparing an emerging walling
material Cement Stabilized Earth Blocks (CSEB) with conventional materials such as
Burnt Clay Bricks (BCB) and Cement Sand Blocks (CSB). Technique for Order
Preference by Similarities to Ideal Solution (TOPSIS) had been carried out to compare
and rank the respective walling materials under different scenarios. Accordingly,
CSEB is concluded to be the best alternative when analyzed in the eco-design concept.
Furthermore, individual analysis of ecological and economic themes shows that CSEB
is the best material over the long run while BCB is said to be performing well socially
and culturally.
The proposed framework could be highly beneficial for industry practitioners such as
contractors, building developers, planners, and policymakers in choosing communitypreferred,
affordable, and environmental-friendly construction materials. Moreover,
this piece of research could be improved with the inclusion of fuzzy numbers which
enables consideration of uncertainty. |
