The consumption of lighting energy in buildings continues to rise, and many studies are being conducted address this problem. As part such initiatives, research is performed on light shelves, which natural systems. However, most prior focused variables for operating flat reflectors shelves. This study aims evaluate the performance curved shelves prove their effectiveness derive optimal specifications them. following conclusions were reached. shelf angles a found be 30ยฐ, 20ยฐ, 20ยฐ summer,...

Numerical analysis, especially the finite volume method (FVM), is one of primary approaches employed when evaluating a building environment. A complicated geometry can degrade mesh quality, leading to numerical diffusions and errors. Thus, this study develops evaluates an automatic simplification based on integrating similar surfaces for indoor space. regression model showed that complexity simplified its similarity original decreased linearly with threshold method. The quality was...
