Background and Aim: Since buildings are constantly exposed to threats, it is necessary that they be fully prepared to confront with all threats and their damages. Therefore, using the passive defense basics and principles in designing and constructing the buildings are considered obvious and undeniable. To prevent or reduce disasters caused by flood, earthquake, and war and so on, solutions such as using smart buildings may be used. Making smart buildings is a way to strengthen the buildings, increasing construction’s longevity, reducing the buildings’ maintenance cost after construction as well as reducing energy consumption during construction.

Method: This descriptive-analytical research is used library studies. First, probable threads to buildings and making smart constructions, as an effective way to reduce risks with passive defense approach, were studied and identified. Then, equipment to making smart buildings in architectural part, in order to preserve defensive assets, was prioritized by using similarity decision making method to ideal option or TOPSIS. 

Results: According to the performance of the smart system in buildings, it can be said that regarding the security of the users, the application of this system in the architectural part of building considering the basics and principles of passive defense will have a greater impact on its protection and security and increase its defensive assets than other parts of the buildings. Therefore, the subsystems of architectural parts in making smart building have been evaluated.

Conclusion: According to the results of TOPSIS analysis in prioritizing the equipment for making smart buildings, smart glasses, smart doors and CCTV, respectively, are introduce as new and dynamic technology which combination with passive defense objectives, facilitate crisis management in each three conditions of before, during and after crisis.
