Abstract:Building insulation materials has a significant impact on building energy consumptions. However, conventional materials are easily flammable and can cause fire disasters in buildings. Therefore, it is important to select appropriate insulation materials for building energy efficiency and safety and Vacuum Insulation Panels (VIPs) are increasingly applied to building insulation. Considering this, the present study investigates energy performance of VIPs with design alternatives, such as window systems, infiltration rates, etc., by using energy simulation. Among various VIPs, fumes silica VIPs were chosen. In addition, eight combinations were compared to find the best energy efficient design conditions. The results of the present study showed that building energy performance can be improved with an appropriate combination of design options including fumed silica VIPs.

As the social demand for high-rise buildings increases, the construction of high-rise apartment buildings is accelerated. As a result of development of such high-rise buildings, societal needs for the safety of high-rise residential buildings against earthquakes and typhoons are increasing. Therefore, wind tunnel experiments were conducted for the safe design of building structures using vibration displacement and vibration acceleration owing to wind loads, and safety analysis and evaluation based on the data obtained through wind tunnel experiments were performed for the safety of apartment building structures. The safety of design standards was confirmed through estimation using the time history data of the measured wind power and evaluation of the average variation components of response to wind direction through spectrum modal analysis. In addition, items such as the quantity of rebars used in the construction of apartment buildings were determined through the field application of the design conducted in accordance with the 2016 Korean Building Code and the design of actual apartment buildings obtained by applying the results of wind tunnel experiments. In particular, the results showed that a seismic design through wind tunnel experiments is required to improve the seismic performance of high-rise buildings.
