Study on Energy Consumption according to Building Envelope Performance and Indoor Temperature

This study aims to suggest an energy consumption improvement plan for university buildings through an analysis of energy consumption. Upon a simulation of subject building to interpret energy consumption, it was found that 154.07kWh/ of energy is consumpted annually. Improvement of design elements can cut down the energy consumption to 135.61kWh/ according to an energy reduction analysis related to envelope performance improvement. Additional improvement of lights and heat exchanger can curtail annual energy consumption to 108.32kWh/. Also, an analysis of energy consumption while increasing indoor temperature gradually showed that the two factors are in proportion. higher temperature requires over twice of the current energy. Based on this survey result, performance improvement due to building management and envelope elements which influence to building cooling and heating loads can curtail building energy consumption.
