A data registry is a physical place to keep characteristics of classes of objects exist in the real world when they are chosen to record as data. It provides a centralized directory to describe the meaning, representation, and identification of data elements and their values. It assists to prevent redundancy and to preserve common understanding about the data described in a metadata set. In this paper, we investigate and classify various components of IBS(Intelligent Building Systems), specially HVAC in Building Automation Systems. We present IBSDR(Intelligent Building Systems Data Registry) model that specifies not only the detailed information on data elements but also the process of documenting data in IBS. It functions as the medium to create the data sharing environment to maintain exact meaning of data for every data elements so that database management designers or related users can create and exchange their DB without major modification. It also serves as a clearinghouse for information about IBS data. So all users can freely retrieve from and register data elements to IBSDR based on ISO/IEC 11179 through World Wide Web.

Maintenance works for current high-rise buildings significantly depend on human labor, unlike other construction processes that are gradually being automated. Herein, this paper proposes robotic building maintenance system using motion control, in specific, reducing a system jerk which is directly subjected to improve the process performance and economic feasibility. The sensor for detecting straight and curvature section of the building facade, moreover rail-joint segment can be detected and be utilized for reducing jerk of the system. Analysis of the proposed system error caused by excessive vibration, e.g. jerk motion is introduced. To enhance the stability and safety of the system, herein, the strategy is proposed for enhancing the performance of the system based on anti-jerk motion control algorithm which comes out increasing the stability and sustainability of the integrated system, as well.
