In this paper, we propose the sensor and the signal duplicator for the automatic building control. Developed duplicator realizes the sensor data collection apparatus and mimics the measured data and, thus, reduces the construction cost by using logical communication layer. Furthermore, the system supports the open protocols and can be associated with HMI(Human Machine Interface) used on the market. Developed duplicator is proved to be functional within the real environment. Measurement error rate, operating temperature, and operating humidity show very good results by the certified testing apparatus and organization.

This research aims at implementing an automation-based building code checking system which will be employed for Architectural Registration Examination. By creating a specific building data model and implementing an automatic building code checking module, the research aims is accomplished. The contribution of this research are as follows; it becomes possible to execute a systematic building code checking. And unlike the existing automatic building code checking systems, it successfully addresses a way of increasing the number of checklist without modifying the system.

Increasing wages and decreasing skilled labors are problems awaiting solution. The development of automatic technologies contributes to accelerating the one of construction automation. Thus, this study is to suggest the way to develop the automated building construction system base on one performed in Japan in order to solve urgent problems of construction industry in Korea. Therefore interviews and questionnaires were performed based on experts who work for the automated building construction system field and analyzed through analytic hierarchy process. In doing so, it was the most important factor to develop a branch of automatic, mechanical or machine technologies for the automated building construction system. Especially the study indicated the importance of the technologies to substitute skilled labors such as a robot. This research could contribute to developing the automated building construction which is very unique and suitable for construction industry in Korea.

Digital communication networks have become a core technology in advanced building automation systems. BACnet (Building Automation and Control networks) is a standard data communication protocol designed specifically for building automation and control systems. BACnet adopts Master-Slave/Token-Passing (MS/TP) protocol as one of its field level networks. Tn this study, we introduce a method of implementing bandwidth allocation scheme in the MS/TP protocol. The bandwidth allocation scheme improves the capability of real-time communication of the original MS/TP protocol. The bandwidth allocation scheme introduced in this paper can be easily implemented in the existing MS/TP protocol with a slight modification. In this study, we examined the validity of bandwidth allocation scheme using simulation models. The results from the simulation experiment show that the proposed scheme satisfies the requirements of real-time communication.

A design optimization problem was formulated to minimize the volume of an RC building structure while satisfying design constraints on structural displacements under vertical, wind and seismic loads. We employed metamodel-based design optimization using design of experiments, metamodeling and optimization algorithm to circumvent the difficulty of the automation of structural analysis procedure. Especially, we proposed a design approach of repetitive design optimizations by stages with changing the side constraint values on design variables and limit values on design constraints until a satisfactory design result was obtained. Using the proposed design approach, the volume of the RC building structure has been reduced by 53.3 % compared to the initial one while satisfying all the design constraints. This design result clearly shows the validity of the proposed design approach.

Wireless Sensor Network(WSN) has been very popular in unattended surveillance systems recently. For Applying WSN into Building Automation system(BAS), a novel hierarchial network structure and static routing algorithm which eliminates the scalability limitation of Zigbee are proposed in this paper. The static routing algorithm relying on the hierarchial network address reduces the computational complexity to a great extent and has a real-time performance which satisfies urgent applications well.
