Indoor Thermal Comfort Condition Analyzing In Naturally Ventilated Rural Houses of Dhaka Region, Bangladesh

Saima Sultana, Mian Md Jawad Ibne Iqbal — Tue, 10 Oct 2023 00:00:00 +0530

Thermal comfort has become one of the most
pressing problems for people all around the
world as global warming worsens.
Bangladesh is an economically prosperous
country with a large rural population living
in substandard housing. Because these
dwellings are in a tropical climate, they are
frequently built from locally accessible
materials such as mud, wood, bamboo, straw,
jute stalk, grass, and so on. These materials
are being replaced by brick, corrugated
galvanized iron sheets, cement, concrete, and
other materials as a result of increasing
industrialization, technical improvement, and
the improving economic status of rural
people. The purpose of this article is to show
the current thermal state of three types of
naturally ventilated rural dwellings made of
two different materials in the Dhaka region.
As part of the study approach, a field
investigation and a questionnaire survey were
carried out. For the comparative examination
of three types of dwellings, the existing values
of the thermal comfort variables
(temperature, humidity, and air velocity)
were used. The analysis demonstrates that the
double-heightened mud home is more
pleasant in terms of thermal comfort factors
and psychological reactions of the residents
than the single-heightened mud house and C.
I sheet constructed houses in a specific
climatic location. This study intends to
indicate that thermal comfort varies with
different building materials and construction
techniques in the same climatic situation, and
so further research and material-based
studies should be conducted to ensure the
thermal comfort of rural residents.

Index Properties of Marginal Clay Soils Treated with Sawdust Ash and Cement

Sadik Iliyas, Ahmad Idris, Ekejiuba Valentine N — Wed, 03 Jan 2024 00:00:00 +0530

This research endeavours to evaluate the efficacy of incorporating marginal lateritic soil with ordinary Portland cement (OPC) and Sawdust Ash (SDA) for soil stabilization, considering the exorbitant cost and environmental detriments associated with industrialized stabilizing agents (such as cement, lime, and bitumen) during their production. The soil utilized in this study was procured from a borrow pit situated along Bauchi-Gombe Road, in the Inkil town of Bauchi Local Government Area, Bauchi state, Nigeria. The soil falls under the A-7-6(28) classification by the American Association of State Highway and Transport Officials (AASHTO), and the CH classification by the Unified Soil Classification Systems (USCS). Various concentrations of ordinary Portland cement (OPC) and Sawdust Ash (SDA), ranging from 0% to 9% and 0% to 10%, respectively, based on the dry weight of the soil, were blended. Specific gravity, particle size distribution, and Atterberg limit tests were conducted on both the natural and treated soil samples. The liquid limit steadily decreased from 61.7% for the natural soil to 30.1% at a composition of 6% OPC and 6% SDA. The plastic limit increased from 26.8% for the natural soil to 15.2% under the 6% OPC and 6% SDA treatment. Consequently, the plasticity index decreased from its initial value of 34.9% for the natural soil to 9.9% at the 6% OPC and 6% SDA composition. Notably, these proportions align with the stipulated requirements for liquid limit, which should not exceed 50%, and plasticity index, which should not surpass 30%, as applicable to roadway construction and engineered waste containment facilities.

Urban Parking Assessment along Major Corridor of Birendranagar Surkhet

Amrit Khatiwada, Janak Bdr. Rokaya — Sat, 23 Dec 2023 00:00:00 +0530

Parking management is a critical concern in
urban areas, and Birendranagar, serving as
the capital of Karnali Province, faces
numerous challenges related to parking.
Extensive surveys have been conducted to
assess parking conditions during peak traffic
hours, collecting essential data for a
comprehensive analysis. This paper focuses
on a thorough examination of parking
dynamics, including vehicular flow,
composition, efficiency, and adequacy. The
study places particular emphasis on Yari
Chowk, currently the most bustling
intersection in Birendranagar, and prioritizes
it for a detailed evaluation. The research
employs methodologies similar to established
traffic studies, utilizing the gathered data to
provide valuable insights into parking
management and traffic flow optimization for
the specified intersection.

Explore the Barrier-Free Design in Public Buildings

Satpal ., Rahul ., Tikam Singh, Bhumik Kumar — Wed, 03 Jan 2024 00:00:00 +0530

Public buildings in Indian cities are in some
way not accessible to everyone, including the
elderly, people with disabilities, young
children, etc. Most people who believe them to
be "normal" people have forgotten that
environmental accessibility is a crucial
concern. People still struggle to demand their
right to an "environment free of barriers,"
thus in this study we may look into their
issues and attempt to address them as well as
provide them with freely independent
surroundings and services. Therefore,
architects, urban designers, and landscape
architects need to take into account the needs
of those who have disabilities and support
them in leading independent, self-determined
lives. Barrier-free planning in this context
refers to construction that eliminates
obstacles for children, the elderly, and
individuals with disabilities. In this study, any
relevant constraints that users were clearly
described, along with how specific elements of
the built environment can act as obstacles for
those who have these limitations. They
identify planning-related needs for various
user groups using this as the background. The
evaluations of barrier-free design in a
constructed environment are the main subject
of this study.

Public Transportation Assessment Along Kathmandu Bhaktapur Route

Sudip Kandel, Sanjay Khadka, Santosh Giri, Sandeep Thapa — Fri, 29 Dec 2023 00:00:00 +0530

The transportation sector of Kathmandu
Valley is facing numerous intricacies because
of soaring population density. According to
the Kathmandu Valley Traffic Police Office,
the number of vehicles that ply the Valley
roads at present is 1.75 million. Just a year
ago, traffic police data showed the number to
be 1.4 million. Also, only about 20% of the
vehicles are used for public service suggesting
that public transportation management has
been a major challenge in Kathmandu Valley.
This leads to an increase in travel time
coupled with huge traffic congestion. The
Kathmandu Bhaktapur route is around 13
KM in length and is used by more than 68000
passengers on normal days and more than
56000 passengers on public holidays; but the
service offered is not reliable and systematic
and needs to be upgraded. Significant travel
duration due to low running speed, and
unnecessary and frequent stops at short
distances proved to be the major issues. After
the removal of unnecessary stations, 3200
passengers’ hours can be saved.
