Environmental forces are the elements or factors that affect the building. Consequently, the building has to be responsive to them in order to control its environmental concept. This paper emphasizes on the impact of using innovative compatible materials in building envelope in order to control the environmental forces, which their systems need to use innovative compatible materials. The environmental forces that will be emphasized on them in this paper are those strategies that are related to and dependent on using innovative compatible materials. These forces are: Thermal force, and Lighting force. Innovative compatible materials can be classified from the technically side to two categories, the first is the conventional environmentally compatible materials and the second is innovative environmentally compatible materials. This paper will address the impact of using Innovative Compatible Materials that comprise the building envelope, and explore innovative qualities, trends, and characteristics. These Innovative Materials include: the conventional environmentally compatible materials and the innovative environmentally compatible materials. This research also will describe only two examples of the innovative materials: smart materials – nano-materials by the description of inputs and outputs of using these materials and assessment of its available environmental applications. In this paper two selected examples for innovative environmentally compatible materials: Smart materials and nano-materials. These examples generally are not environmental but they have some types and applications that is compatible with environment, and those are the examples which will be explained widely in this study.
