Abstract
Environmental problems caused by fossil fuel consumption, on the one hand, and the upcoming prospect of ending these fuels on the other, attracted much attention towards sustainable architecture. Traditional buildings can be seen as a sample of sustainability; as they have used strategies to cope with the environment, which have been developed over the years, providing users’ comfort conditions for centuries. But before implementing these strategies in today buildings, we need to know the exact effect of their use; something that is regularly performed by an energy simulation software. Thus, first, we should know the ability of the software in modeling different design strategies, and secondly we should be certain of the validation of its results. This research aims to study the ability of DesignBuilder software (as one of the most applied software for building energy simulation) to model and simulate a complex traditional building. The accuracy of DesignBuilder thermal simulation results, in comparison with the experimental data is the main question of this study. To do this, Rasoulian house in Yazd (in hot and arid climate of Iran) was chosen as a case study and after simulating the entire building, the simulation results were compared with experimental measurement data. The results show that in most spaces, the experimental data were only 1–5°C different from the results of the simulation. Finally, the probable causes of these differences were analyzed and some suggestions were proposed to develop DesignBuilder, to be more applicable in simulating buildings of hot and arid climate.

Abstract
Disconnection with nature and history as a result of modernist approaches occurred in the early twentieth century has led to great consequences. Climate change, environmental problems and energy and resources crises have posed numerous challenges to contemporary architects across the globe. The present paper focuses on the issue of passive thermoregulation strategies in vernacular and biomimetic architecture - two approaches in architecture that connect architecture to nature and history -which can offer solutions for environmental crisis. The main objective of this study is to highlight the similarities and differences between vernacular and biomimetic architecture based on passive thermoregulation criterion. So the main question is: what are the common features of biomimetic and vernacular architecture in their use of passive thermoregulatory mechanisms. In this study, the comparative method is used to point out the similarities and differences that can be found between some case studies of vernacular and biomimetic architecture. First, some examples of biomimetic architecture are selected using desk studies and, then, their approach to heat regulation are analyzed using descriptive-analytical research methodology. The results show that while vernacular architecture has a static nature and is depended on low-tech and biomimetic architecture has a dynamic (kinetic), intelligence and interactive nature which relies on high-tech and new materials, their approaches to thermoregulation are similar in some ways. While different in form, they are both based on controlling solar radiation through shading, dissipating heat through convective and evaporative cooling systems, and using the sun as a renewable source of energy.
