    A building is an assemblage that is firmly attached to the ground and provides the performance of human activities and need to be considered in the daily operation in that building. The improvements in building performance are focused on improving the energy efficiency of buildings. This is approach by designing heating, ventilation and air conditioning (HVAC) duct system due to one of the most utilized energy in maintaining building performance and environment. The objectives of this research is to calculate the air (CFM) supply in office building, to characterize the velocity and head loss in a round and rectangular HVAC ducting system at various duct thickness and to optimize the thickness of the duct in HVAC system according to ASHRAE Standard. The increasing of velocity in duct system shows the increasing of head loss. The round duct design gives the lowest velocity and head loss in HVAC system approximately around 9.35% as compared to rectangular duct at 0.06 inches thickness. Hence, the trends of the head loss and duct thickness has influenced in reducing noise in HVAC duct system in order to select the best design concepts which is round shape design

    Digitization to Support Generations of Refugees: How Can IS Research and Researchers Make a Difference?

    In recent years, a new refugee crisis has been sweeping the world due to the continuous violence in different places and countries. These developments have caused unexpected challenges on different levels, ranging from individuals (including migrants and refugees and hosting populations) to organizations, countries, and continents (including those fleeing violence and hosting countries of fleeing individuals). Despite the urgency and the potential risks associated with the current refugee situation, relatively little work has been carried out by IS researchers on how to find the intersection between this societal topic and the use of technology to alleviate this crisis. The outcomes of the panel have implications for both academia and practice. We would like to uncover the beneficial use of digital transformation solutions that could help and empower refugees and host communities using the bright side of existing technologies in integrating refugees into society
