As it become crucial to save the planet, mitigate climate change, keep natural resources, reduce pollution, improve quality of life, and overall live in a sustainable environment, a great concern and big efforts are executed worldwide to achieve this target in all fields of life. On the other hand, there is an exaggerated development in the computer science field and the production of software. Accordingly, in the architecture field and especially in the design stage vast number of computer programs came to duty with divergent functions. This paper focuses on software programs and to what extent they can generate a sustainable building in its design stage. This primary stage is the most important phase of the building life, as it can control the building behavior, assures its performance, and mostly secure its end of life. With a proposed design project, the paper states an empirical study using chosen software to extract the real role of these computer programs in achieving sustainable design.
