The Role of Functional Flexibility to Improve Energy Efficiency in Energy Consumption of the Case Borojerdiha house in Kashan

  Man raises level of his needs by falsifying the nature and construction of the built spaces. By examining various aspects and complex dimensions of the human, variable and different needs can be clearly seen. Therefore, an architectural construction, especially housing, should be able to set the access conditions to meet the highest level of the needs and achieve to the highest level of responsiveness to the needs of users. Thus, conditions such as flexibility, adaptability, variability and all the principles that lead to generate opportunities and capacities proportional to user's needs in a building has been double necessary. With looking at the traditional architecture, we find that, despite the limitations in manufacturing technology, the architects used their own strategies for responding to existing problems. Strategies such as the use of multi-functional space, embedding spaces in the three scales of tiny, medium and large scales as well as ability to separate or merge spaces, are some of these items. By knowing, however, Iran's traditional home space is flexible, in this study, we sought to answer the question whether this flexibility in space has a role in the amount of energy consumption of the building? If there is, it has an increasing or decreasing role? In order to answer this question, several examples of traditional houses in the hot and dry climates is simulated that, due to brevity it is not expressed in this study. Among them, for example, is expressed Boroujerdi House and energy consumption of the existing state compared with when a space had not seasonal versatility. Finally, it is concluded that flexibility, reduce energy consumption in traditional buildings.
