Abstract As buildings consume around 40% of total energy consumption, designing and optimizing energy technologies provide important part of building researches. As one of the main elements of buildings, envelopes have significant role in energy consumption. Although different envelope technologies have been developed and launched, understanding the market acceptance and commercial potentials of each technology is important. Therefore, technology assessment of different envelopes from energy viewpoints is in interests of the researchers, engineers, investors, and decision makers. This article is to analyze the diffusion and adaptation of building envelope technologies based on a Hype cycle diagram. The hype cycle diagram combines technologies life-cycle and adaptation of a technology. First, the main building envelope technologies are reviewed. Afterwards, the diffusion diagram of each technology is drawn based on life cycle analysis and patent registrations. Next, the adaptation of each technology is investigated. Finally, by combination of both diagrams for each technology, the situation and future of the technologies will be discussed. The out-puts have been also verified based on a scientific approach.
