The major purpose of this article is to compare two prevalent light weight structural systems: Light Gauge Steel structural systems and 3D Wall Panels to find out which system is more compatible with sustainable construction aspects. To achieve this desire, the research procedure begins by defining the concepts of sustainability in residential construction, following by a brief explanation about each system. Then a sample residential plan is applied for each light weight systems with similar conditions. Afterwards two plans are compared considering sustainability aspects. The structural analysis and design of Light Gauge Steel systems has been carried out using STRAP software, while 3D Wall Panels has been designed in ETABS. Statistical data of the projects is estimated according to previously performed project schedules. As a result, although both Light Gauge Steel and 3D Wall Panels Systems do not completely fulfill sustainability aspects, each of the two systems precedes in some.
