An Analysis of Environmental Performance and Improvement of the Envelope for High-Rise Residential Buildings

Due to high-rise residential buildings and extension of balcony, to resolve discomfort ofindoor-environment and the problem which energy consumption increases, high-riseresidential buildings, coming natural ventilation and decreasing expense of an airconditioningsystem., enable envelope system to be developed.The object of this study is to present the improvement on envelope of high-rise residentialbuildings to reduce heating and cooling load. To improve the environmental performance ofenvelope, it is necessary to modify envelope vent system and ensure intermediate space.In this study, the shape of vent in high-rise residential buildings has been inspected, and thesurvey about the environmental conditions related to the envelope of high-rise residentialbuilding has been conducted. Environmental measurement has been done to examine out doorair quality for natural ventilation.
