Vertical meteorological conditions encountered by super tall buildings, such as wind speed, temperature and humidity, vary due to their height. Therefore, it is necessary to consider these environmental changes to properly estimate the heating and cooling loads, and to minimize the energy demands for HVAC in super tall buildings. This paper aims to analyze how vertical meteorological changes affect heating and cooling loads of super tall buildings by using numerical simulation. A radiosonde, which observes atmospheric parameters of upper air such as wind speed, wind direction, temperature, relative humidity and pressure, was used to provide weather data for the building load simulation. A hypothetical super tall building was used for the simulation to provide quantified characteristics of the heating and cooling loads, comparing the lower, middle and upper parts of the building. The effect of weather data on the heating and cooling loads in super tall building was also discussed.

The paper describes the conceptual design, structural modelling and wind load analysis of tall buildings. The lateral stiffness of the building can be obtained economically through the interaction of core walls with peripheral frame tube and/or bundle of frame tubes and integrated design of the basement. The main structural components should be properly distributed such that the building will deflect mainly in the direction of the applied force without inducing significant response in other directions and twist. The cost effectiveness can be further enhanced through close consultation between architects and engineers at an early stage of conceptual design. Simplified structural modelling of the building and its response in three principal directions due to wind load are included. Effects of the two main structural components on the performances of a 70-story reinforced concrete building in terms of peak drift and maximum acceleration under wind load are discussed.

This study aims to suggest a direction to develop Korea's certification system by comparing the evaluation items between Korea's G-SEED (Green Standard for Energy & Environmental Design) and Germany's sustainable building certification. A number of eco-friendly building certification systems are being implemented globally. On the other hand, mutually comparable evaluation items have not been suggested up until now. Therefore, international standards have been trying to establish evaluation criteria for eco-friendly buildings, and Germany's sustainable building certification is the first certification standard that has accepted those evaluation criteria. According to the result of comparing Korea's green building certification with Germany's sustainable certification, the green building certification has evaluation items not only on environmentality (62.6%), but also on social aspects (25.4%) and economic aspects (3.0%). This suggests a crucial direction to the development of evaluation items regarding the social and economic aspects of green building certification.

Concerns about green building construction were quite increasing around the world. Therefore, Korea Government has executed the Green Building Certification Criteria(GBCC) in 2002. The GBCC of educational facilities was executed in 2005 and was revised in 2010. The aim of this paper is to check the reliability of weighting factors in all assessment categories of GBCC and to suggest the future revision direction of GBCC. For the study, the old and current version of GBCC were examined and the 5 cases certificated by the old version were analyzed and reassessed by current version to compare with the differences of the two in obtaining the green building certification. According to the results of the study, the GBCC requires additional amendments about the assessment categories of the energy consumption monitoring and building commissioning as required subjects in order to secure the stable performances of building. In addition, the categories of building management need to be assessed more intensively and the certification criteria for existing building should be enacted as soon as possible.
