This paper introduces technology analysis and optimization method. Rhinoceros, an architectural modeling program, is used, along with its graphical algorithm editor Grasshopper and its plug-in, ladybug and honeybee, with a simplified tool for building thermal evaluation for the purpose of minimizing the energy consumption and maximize the useful daylight illuminance of an office building in China Beijing. The introduction of technology analysis and optimization methods, provides a generation of practical global optimization and solution strategy for building design for different majors
