Abstract:

Reducing the energy consumption of the buildings in Iran is essential, since the building energy consumptions in the country are about 40% of the total energy consumption. Approaches and strategies to reduce the level of energy consumption in buildings can be investigated in two main parts: designing energy-efficient buildings and energy efficiency in existing buildings. With the advent of various technologies, complexity and administration costs are also increased. Therefore, the decision-making about the selection of optimal strategies and finding the solutions to reduce the energy consumption in buildings has become more important. On the other hand, the interaction between the design elements, climate, users, cooling, heating, ventilation, and lighting is very complex and can only be studied by simulating all of the influencing factors in the energy efficiency of the building. Since the building shell as the separator of the interior and exterior environment plays an important role in the thermal behavior of the buildings, in this article, the use of double skin facades was investigated, as a new technology that is designed as an obstruction which creates a balance between the interior and exterior environments. Based on the results of this study, it was concluded that if this technology is properly used and implemented in the designing process of the buildings, it could have an important role in reducing the energy consumption of buildings, as well as several side benefits.

Machine summary:

Since the building shell as the separator of the interior and exterior environment plays an important role in the thermal behavior of the buildings, in this article, the use of double skin facades was investigated, as a new technology that is designed as an obstruction which creates a balance between the interior and exterior environments. In the contemporary world, with the use of new materials and intelligent technology, this idea is gradually taking shape that the facade of the building to be designed or implemented should be like a skin or intelligent shell which withstands some of the external factors, shows different actions, and takes advantage of some natural environment phenomena. Recent studies showed that the energy performance of a building connected to a double-skin facade can be improved either in cold and warm season or in cold and warm climates by optimizing the ventilation strategy of the façade (Mingotti et al. The Design Builder software was used for thermal simulation; the result verified that the total amount of energy consumption of the models with an optimized double-skin facade for warm and dry climates was 14. Implementation of energy management and the use of new methods and technologies in buildings like double skin facade are the ways which reduce the costs and increase the welfare of the users. Double skin façade impact in reducing energy consumption in high-rise buildings. Double skin facade new technology to reduce energy consumption in buildings.
