Abstract Most architects rely on aesthetic intuition, often neglecting the mathematical foundations that underlie aesthetic judgement in design. This study addresses this gap by proposing a mathematical framework that supports both aesthetic excellence and low-carbon performance in architecture. The first contribution is to identify the essence of modular aesthetics as rooted in classical mathematical constructs—ratio, sequence, and spiral.

Abstract Chain hotels constitute 40.09% of all hotels, with indoor room decorations typically undergoing replacement cycles every 2 to 5 years. Robotic 3D printing-enabled prefabrication offers transformative potential for sustainable construction, combining precision engineering with environmental consciousness. This study explores its application in the hospitality sector, addressing both sustainability and ergonomic data.
