Abstract

Natural ventilation is most desirable for cooling and providing fresh air in residential buildings for better indoor air quality and thermal comfort. The natural ventilation performance is affected by a combination of internal and external factors. External factors include the location, the orientation, the prevailing wind speeds and the building forms of the residential development, which are subject to constraints beyond the control of site planners and architects. Whilst for internal factors like the openings configurations and window types, site planners and architects are always given free hand for a proper design. Dhaka, a city in the Tropics, has become such a city where with rapid urbanization users are moving towards mechanically ventilated buildings putting ever increasing demand on the dwindling energy resources. This paper focuses on the influences of window types on the natural ventilation of residential units in Dhaka in order to improve quality of indoor living environment. Primary objective of the study is an attempt to investigate the performance of different types of windows which is commonly used in residential buildings of Dhaka city. It is expected that the findings will immensely help design professionals practicing all climatic contexts where ventilation is an important design consideration.

...Proceedings of MARTEC 2010 The International Conference on Marine Technology 11-12 December 2010, BUET, Dhaka, Bangladesh STUDY ON SOME COMPETITIVE PARAMETERS FOR SHIPBUILDING INDUSTRY IN BANGLADESH N. M. Golam Zakaria, M.M. Rahaman and Kh. Akhter Hossain Department of Naval Architecture and Marine Engineering, Bangladesh University of Engineering and Technology, Dhaka, Bangladesh gzakaria@name.buet.ac.bd ABSTRACT Despite Bangladesh has glorious history & heritage as a shipbuilding nation since ancient time, shipbuilding has been in focus only from the last couple of years. The optimism about this industry arose from the success attained by a number of local entrepreneurs who brought the name and fame to Bangladesh as a country with great potentials in shipbuilding by building and handing over some ocean-going vessels to overseas buyers. Since then, the shipbuilding in Bangladesh did not have to look back and now new opportunities are knocking at the door to flourish this industry further. However, due to global nature of this industry, an assessment of suitability to modern shipbuilding in terms of global standard is of prime importance. This paper focuses on studying some crucial competitive factors like labour skill, labour availability, labour man-hour, labour cost & productivity for local shipbuilding which are the inherent part for expansion of this industry. The analysis also focuses on the existing access to the resources like materials, knowledge and capital for......

Natural Calamity in Bangladesh

...A natural disaster is the effect of a natural hazard. Bangladesh, a country in southern Asia that is home to 140 million people, is widely known as a land of natural disasters. It is highly vulnerable to floods, famine, drought, earthquake, cyclones, and river erosions. Due to the effects of these disasters, the country is now permanently in distress. These disasters have become regular phenomena and have been causing suffering to millions of residents for many decades. Natural Disasters are occurring every year in our country. And so found to suffering in it. In Bangladesh Natural Disasters can be of many different kinds, but We suffer most, Some of this like floods, cyclones, earthquake and river erosions. The similarity in all is their massive destruction in the area of their occurrence. In the wake of all these, in one sweep there is complete devastation and destruction, due to which normal life comes to a standstill. Loss of life is well high complete, and belongings of people get lost, blown away or swept away. In Bangladesh we depends on the annual rainfall for our source of water, if there is no rain, for the water supply, the obvious famine comes in its wake.

Success of Microfinance in Bangladesh: Its Determinants, Impacts & Challenges

... Success of Microfinance in Bangladesh: Its Determinants, Impacts & Challenges Chapter- One Introduction 1.1 Introduction: In recent years, microcredit, in its wider dimension known as microfinance, has become a much favored intervention for poverty alleviation in the developing countries and least development countries. There is scarcely a poor country and development oriented donor agency (multilateral, bilateral and private) not involved in the promotion (in one form or other) of a microfinance program. Microfinance programs claim many achievements as its impact and an outside observer cannot but wonder at the range of diversity of the benefits claimed. Although Bangladesh has huge potential for development, it is, for various socio-economic reasons, among the poorest countries in the world. About half of the country's population lives below the poverty line with 80% in the rural areas. The burden of poverty falls disproportionately on women, who constitute half of the total population. Logically, therefore, poverty alleviation and creation of rural employment are top priorities in the development agenda of the government of Bangladesh (GOB) which has adopted a broad based approach to poverty alleviation, emphasizing macroeconomic stability, economic liberalization, and support for a number of government agencies and non-government organizations (NGOs). Substantial progress has been made in implementing the microcredit program (MCP), and the scope for its......

Impact and Adaptation to Climate Change in Bangladesh

...South Asia is the most vulnerable region of the world to climate change impacts (McCarthy et al., 2001). The international community also recognizes that Bangladesh ranks high in the list of most vulnerable countries on earth. Bangladesh’s high vulnerability to climate change is due to a number of hydro-geological and socio-economic factors that include: its geographical location in South Asia; its flat deltaic topography with very low elevation; its extreme climate variability that is governed by monsoon and which results in acute water distribution over space and time; its high population density and poverty incidence; and its majority of population being dependent on crop agriculture which is highly influenced by climate variability and change. Despite the recent strides towards achieving sustainable development, Bangladesh’s potential to sustain its development is faced with significant challenges posed by climate change (Ahmed and Haque, 2002). It is therefore of utmost importance to understand its vulnerability in terms of population and sectors at risk and its potential for adaptation to climate change. Increased climate variability means additional threats to drought-prone environments and is considered a major crop production risk factor. The impact of climate variability and change on agricultural production is a global concern. However, the impact is particularly important in Bangladesh where agriculture is the largest sector of economy, accounting......
