Abstract This study is based on labor intensive factory, located in Dhaka, Bangladesh which was adversely impacted due to extreme hot conditions. The analysis started with the implementation of green roof (GR) as one of the passive design strategies to reduce indoor heat stress. Impact of indoor heat stress indicated by wet bulb globe temperature (WBGT) and prediction of heat strain (PHS) model for green roof have been evaluated through numerical studies and indoor environmental data of local fa...

Abstract From field monitoring, it has been observed that in readymade garments (RMG) production spaces, thousands of workers have been worked day long and might have probability of different thermal perceptions. As thermal comfort is the crucial phenomenon for workers, for the reduction of excessive indoor heat, using HVAC cooling strategies are the most critical segments in energy consumption. This paper describes an experimental study about assessment of different indoor environmental steps t...

Abstract In recent years, due to lack of considerations of indoor thermal condition as well as increasing global temperature has led to rapid increase of heatstroke patients at workplaces. In such context predicting overheated environment is becoming an imperative for the industry. From field monitoring, it was observed that production spaces in Readymade Garments (RMG) were adversely impacted by excessively hot indoor environments, and yet thousands of workers toiling away their days doing prod...

Urban wet lands and water bodies can reduce overheating of the urban environment as well their general function of natural water purification. Nonetheless, urban wetlands are either diminishing or contracted from their original shape and size due to pressures from the housing sector and unplanned urbanisation. This chapter presents the findings of a study investigating into the possible relationships existing between water quality of urban and peri-urban water bodies and three selected parameter...

Abstract In this research the thermal performance of ready-made garments (RMG) factory building's envelope has been measured on the basis of internationally established indoor thermal comfort range for the workers. A three-dimensional model has been developed to conduct thermal simulations for typical RMG factory. The simulated factory has been divided into three different zones based on their activities and results have been analyzed by means of statistical distributions. Two types of variables...

In Bangladesh, Ready-made garment (RMG) sector is fully supported by the workers who labour in the production spaces of garments factory buildings throughout the day. Appropriate Illumination conditions of these production spaces, which indicate the quality as well as quantity of lighting suitable for the production processes, is a major requirement. As indoor environments of these spaces are becoming highly complex, working under poor lighting conditions are usually exposed to a variety of visu...
