Human beings are susceptible to the force of nature. They had to make shelter for themselves. Material was one of the most basic tools to create shelter. By development of building construction, selection and use of materials also developed. The relationship between the architecture and the materials before invention of modern materials was simple and generally naturally [1]; in the past, architects always use tradition materials according their experimental skills. For choosing structural materials, they had attention to important factors such as availability (local materials) and harmony with climate and culture [2], although this way was forward with feedback. But this relationship was not continuing simply.
The industrial revolution was …show more content…

Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli [8] that provide architects with more opportunity to design that are environmentally sustainable. According to early definitions, smart materials are materials that could respond to their environments in a timely manner [9]. With a look to characteristics of smart materials, we discover that they directly focus on their actuation events and the ability of prognosis, immediate response to the environmental conditions. The external stimuli, Light, Temperature, Pressure, Electric field, Magnetic field and Chemical environment [2] on smart materials cause different effect on smart materials. Addington and Schodek say “The behaviour of a material is dependent upon its interaction with an energy stimulus” [1]. Smart materials according their response to external stimuli classify to three groups: Property change, Energy exchange and Shape memory alloy [9]. Smart materials are often described as adaptive or intelligent materials [2]. Because of this adaptivity, also increases the option space for saving energy while at the same time supporting favourable comfort conditions [10]. With the aim of developing and encouraging appropriate energy policies for the future, it is required to gain an understanding of professional views in all countries, as well as those with extensive fossil fuel reserves [11]. Smart Materials are a particular type of materials that have recently received considerable attention in the international construction industry because they suggest the feasibility of preparing clean energy sources for buildings in aesthetically and architecturally fascinating ways
