Abstract In response to the goal of building sustainable cities under the condition of increasing urbanization, the improvement of capabilities in managing building stocks in urban area is becoming an important task. John Wilmoth, Director of UN DESA’s Population Division, says “Managing urban areas has become one of the most important development challenges of the twenty-first century.Our success or failure in building sustainable cities will be a major factor in the success of the post-2015 UN development agenda.”(United Nations,2014).The concept such as “smart city” and city “digital twin”(DT) were proposed in recent years. We need to make sure the city leaders are equipped with the data and tools they need to make effective decisions.However, currently in the decision-making stage the high-detailed building data information is usually separated from the low-detailed three- dimensional model when we describe buildings from single building scale to the urban community scale.This separation of building data creates a lot of uncertainties and difficulties to optimize the decision in community level scenario simulation.So in the building management approach one of the challenges is to provide different stakeholders an integration platform at the both urban-scale and building-scale for monitoring and analyzing the behavior of the building stocks.
