Throughout the last decade, environmental topics in architecture start to gain interest to preserve natural resources, and to improve the performance of designs. One of the great problems facing architects, is checking whether their designs compromise with the environmental needs or not. Thermal performance is one of the main issues related to environmental design. This research proposes a framework for thermal design of envelopes, by simulation and optimization of building envelopes based on computer algorithms and environmental simulation programs. Through analytical methodology, main optimization algorithms and thermal design parameters are analyzed to achieve the framework. It explains the essential concepts of computer programming, and how it is integrated into the architectural design process to achieve thermally efficient envelope. Designer is introduced to computer programming from a theoretical point of view, with an explanation of the types of input needed by the algorithms. In order to achieve this, different types of algorithms and their output, how to define the optimization problem and its variables, the different types of 3D virtual modelling and environmental simulation programs and their role in the process, are discussed. The framework can be summarized in the following steps: building envelope analysis in terms of geometry and its categorization, determining the thermal criteria and target performance, modelling and simulation of the building envelope, and finally applying algorithm and optimization of the envelope’s thermal performance.
