Several factors, such as the age of the building, type, climate, building technique, location, MethodologyĪccording to the above and with regard to the necessity of energy consumption in the buildings, recognizing acceptance and adaptation of each building envelope technologies are important to help investors, policy makers, and researcher. Therefore, the quality and power performance of the building envelope are the most critical parameters that influence the energy demand in the buildings. The rate of radiation absorbed by buildings can be reduced by using new technologies. Sections of a building which is the main thermic buffer within the outer and inner have a fundamental impact on the level of convenience and required energy level. Finally, the key points of each technology in the diagram is extracted. The diagram has been validated by reviewing the opinions of the experts and scientists and compared by a valid scientific source. By combining two noted diagrams, hype diagram for each technology will be achieved. Our next step is drawing the adaptation diagrams of each technology. Then, by using information collected via registered patents the lifecycle curve of each technology is drawn. As one of the best tools for assessment of each technology is Hype cycle diagram, we provide an overview of the maturity and acceptance of the building envelope technologies and their applications.įirst, we introduce the main technologies of building envelope and their role in reducing energy consumption. Considering the role of envelopes, accurate assessment about different technologies and their markets and economics potentials will help investors and policymakers to realize the investment and decision opportunities for energy efficiency plans and programs in the building industry. Given the importance of energy consumption in the building industry, identifying the most important technologies, and the current status and future development of each technology in the market and researches are important. However, several economics, technical, and even cultural factors influence the diffusion of the technologies. The effective use of energy and energy savings used in the building's envelope is strongly dependent on the diffusion of existing technologies in the market. In cold conditions, the share of passive heating could be strengthened by optimizing the building design and utilizing modern windows and glazing systems. In a hot climate, low-price methods including roofs and walls with reflection outer shade coat, and low-radiation window envelopes could reduce the energy usage for cooling the building too. It is the physical separator between the conditioned and unconditioned environment of a building for resistance to air, heat, noise, light, and water. Īmong different elements of a building, envelopes are one of the important parts in for the studies of energy consumption. Therefore, the focus on energy consumption in the building is very important for policy makers and researchers. Indeed, other sectors such as industry are also consumed energy for their building. The major part of energy in the mentioned sectors are consumed for heating and cooling systems of the building. According to IEA statistics, the residential and commercial/public sectors consumed around 30% of total final consumption in the world on 2015. To respond the challenge, two main strategies have been developed by the governments: diffusion of renewable and green energies, and efficacy in the energy systems and structures. However, limitations in fossil fuels supply and their environmental effects have caused serious threats for societies too. With increasing population and welfare, the demand for energy is increasing very fast. The out-puts have been also verified based on a scientific approach. Finally, by combination of both diagrams for each technology, the situation and future of the technologies will be discussed. Next, the adaptation of each technology is investigated. Afterwards, the diffusion diagram of each technology is drawn based on life cycle analysis and patent registrations. First, the main building envelope technologies are reviewed. The hype cycle diagram combines technologies life-cycle and adaptation of a technology. This article is to analyze the diffusion and adaptation of building envelope technologies based on a Hype cycle diagram. Therefore, technology assessment of different envelopes from energy viewpoints is in interests of the researchers, engineers, investors, and decision makers. Although different envelope technologies have been developed and launched, understanding the market acceptance and commercial potentials of each technology is important. As one of the main elements of buildings, envelopes have significant role in energy consumption. As buildings consume around 40% of total energy consumption, designing and optimizing energy technologies provide important part of building researches.
