  • Rethinking Use of Individual Room Air-conditioners in View of COVID 19

    • Authors: Raja Singh; Anil Dewan
      Abstract: As the World Health Organization is examining the airborne nature of COVID 19, there is past research on other airborne infections which set all encompassing guidelines. Even as more data begins to be available regarding COVID, there is proven spread of airborne disease like tuberculosis being transmitted by this route. As the summer months approach, there is an increased use of Air Conditioners in the tropical regions of the world. India, too being in this part of the world sees an active rise in the indoors which are being air conditioned to meet the thermal comfort requirements of the rising urban population which is spending a large chunk of time indoors. This is coupled with the enforced lockdown which encourages people to stay indoors to prevent the spread of infection. In such situations the use of Room air conditioner requires rethinking as they re-circulate the indoor air without any Fresh air supply into the room. To reduce heat gain and save the electric load of the room AC, people tend to seal the windows further. This paper looks at many possible ways of finding out infection spread in spaces and one of them is used to find out the probability of airborne infection spread in a typical public space. An experiment to validate the same has been conducted in a classroom setup with results analysed. Increased ventilation has been demonstrated to show a lesser probability of infection spread.

  • Critical Review of Street Connectivity Between Tejgaon Industrial Area and
           Adjacent Hatirjheel Development

    • Authors: Sharif Tousif Hossain
      Abstract: Tejgaon’s development process was initiated in the 1950s by the Department of Public Works (PWD) as an industrial zone and it was also indicate in the first master plan of Dhaka (1959). In1968, Tejgaon was designed as light industrial area by the Dhaka Improvement Trust (DIT). After Liberation war in 1971 Tejgaon become the most sought after place for industrial activity for not only its being on the outskirts of the than city center but also for the rising demand for the growing population of Dhaka. Several residential areas were developed beyond Tejgaon industrial areas (TIA) resulting in the rapid transformation of land use at this point into a mixed use development changing the physical characteristics of TIA. Responding to this transformation, the Government of Bangladesh has decided to develop Tejgaon industrial area as commercial cum residential hub. At the same time low lying areas i.e. Hatirjheel area on the south of TIA was developed to connect the northern residential areas (beyond TIA) with the older urban core. TIA thus came in between Hatirjheel development and Northern residential areas as such requiring rethinking of the street connectivity in the area. Transformation of TIA and the development of Hatirjheel provides an opportunity to rethink about the  connectivity of road network. This study critically reviews the street connectivity between TIA and the adjacent new Hatirjheel development. It is identified that the new Hatirjheel development did not take note of the older TIA road network thus creating problem of urban mobility and integration. This study aims at identifying the street connectivity by quantitative and qualitative method using tools like Depthmapx10 to understand the new dynamics and suggest measures for better urban mobility.
