REDESIGNING AND FABRICATION OF EXISTING DUCT SYSTEM

Buildings’ ability to maintain thermal comfort and indoor air quality depends heavily on their duct systems. However, many of the current duct systems have inadequate design and manufacture, which results in subpar performance and energy waste. The goal of this review paper is to provide an overview of recent developments in the redesign and fabrication of existing duct systems, including the use of computational fluid dynamics (CFD) simulations, sophisticated fabrication techniques, and smart materials that create a network of airflow pathways through buildings. These systems, however, may eventually become out-of-date, ineffective, and in need of revision. In this article, we evaluate current innovations in the redesign and fabrication of existing duct systems, emphasizing improvements in materials, manufacturing processes, and design methodologies.
