Abstract— Globalization on one end has increased urbanization but on the other extreme was a major parameter of depletion of non-renewable resources. United Nation as a custodian of human rights has provided a long-term strategy of sustainability-Vision 2030 a long-term perspective that was initiated in 2015 having 17 sustainable development goals (SDGs) constituting 169 global targets related to the SDGs with a focus to improve the social, economic and environmental concerns of a human being". Sustainable building of cities and communities is its 11th SDG. This paper provides a sound basis to use building performance simulation (BPS) in buildings to reduce the level of energy consumption in Saudi Arabia (KSA). A Survey was conducted evaluating the knowledge of BPS around the construction community along with a case study that is done to analyze the impact of BPS on overall energy efficiency. The results reveal a mixed knowledge level of the audience where most people are unaware of BPS and the professionals also have a very diminutive knowledge of this. However, it was observed that BPS has wide applications in building design as 50% energy efficiency is achieved as compared with the traditional approach of designing. The study discloses the fact of boosting up a country's economy by application of BPS as it lowers the energy consumption and carbon footprints. Moreover, a relationship of BPS with customer satisfaction and a framework for implementing sustainability in architectural projects are also suggested.
