Since data-driven building technologies have been widely applied to building energy systems, the accuracy of building sensors has more impacts on the building performance and system performance analysis. Various building sensors, however, can have typical errors including a random error (noise) and a systematic error (bias). The systematic error is indicated by the difference between the mean of measurements and their true value. It may occur due to the sensor’s physical condition, measured phenomena, working environments inside the systems. Unfortunately, a conventional calibration method has limitations in calibrating the systematic errors because of the difference between working environments and calibration conditions. In such situations, a novel sensor calibration method is needed to handle various sensor errors, especially for systematic errors, in building energy systems having various thermodynamic environments. This study proposes a building sensor calibration method named Virtual In-situ Calibration (VIC) and shows how it is applied into a real building system and how it solves the sensor errors.

Airflow in building caused by stack-effect may have a significant impact on heating load in high-rise residential buildings under winter season in Korea. While, building load caused by airflow is considered as infiltration only in a conventional building load calculation. However, with the building height is higher and higher and the outdoor air temperature is colder and colder, the airflow caused by stack-effect in a high-rise building seriously affects on building load. Therefore, it is necessary to consider the airflow caused by stack-effect in calculation of the building load. In this paper, the effect of airflow caused by stack-effect on heating load in a high-rise residential building will be analyzed by measurement and whole building simulation method.

Building energy management is one of the most important issues in these days. In this study, the building energy management system was discussed to increase the efficiency of building energy management. This system is based on the 3D spacial information model and 3D HMI(Human Machine Interface) and includes modeler, manager, monitor, simulator and server. Building energy can be monitored and controled efficiently by using this system. This paper will suggest the building energy management system.
