The article examines the problems of construction and design of buildings and structures in tropical areas of Vietnam, formulated the principles of their construction. It demonstrates that the comfort principles are correlated with the corresponding composition techniques and methods are implemented in a system architecture approach Urbanized shaping medium using methods lighting calculations that take into account parameters of the light and climate conditions insolation simulation method for building layouts.
