Ventilation is essential to maintain a healthy indoor environment. However, in summer and winter, thermal conditions of outdoor air are so poor that ventilation cannot but increase energy consumption. Thus, energy-efficient ventilation system is very important. Thermal labyrinth system is a ventilation system which intakes outdoor air through an underground concrete structure shaped like a labyrinth. By the heat exchange with ground, this system can precool and preheat the outdoor air in summer and winter, respectively. The aim of this study is to analyze the energy efficiency of thermal labyrinth system, applied to the E University building recently built in Seoul, in summer and autumn (from Aug. 1 to Nov. 30). As results, it was found that average cooling and dehumidifying effects of thermal labyrinth system in Aug. are 3.7℃ and 3.1gw/kgda (9.92kW and 18.51kW),respectively, and average heating and humidifying effects in Nov. are 8.7℃ and 0.7gw/kgda (19.50kW and 3.89kW), respectively. Total outdoor air sensible and latent, cooling and heating load was found to be reduced by 38.8% through the thermal labyrinth system

This study aims to evaluate insulation performance of aluminum and PVC framed double glazing window systems with low-e coating and insulation spacer by the heat transfer simulation. To the aluminum and PVC framed double glazing window systems with and without low-e coating and insulation spacer, U-factors of each part and total window system were calculated for the evaluation of energy performance. Also temperature difference ratio was derived from the lowest inside surface temperature for the evaluation of inside surface condensation under the various conditions of inside air temperature, humidity and outside air temperature. The results show that the application of low-e coating and insulation spacer can substantially increase the energy performance and temperature difference ratio for preventing inside surface condensation, respectively.
