Recently, curtain wall system has been applied to much more high rise buildings because of its convenience of construction. However, inside surface condensation on the curtain wall systems still has been a problem. The aim of this study is to suggest design criteria to prevent inside surface condensation on the curtain wall systems of office buildings. A variety of criteria including codes, standards and specifications of Korea and other countries were analyzed and the lowest temperature factor of 0.7 for Seoul was suggested as design criteria. In case of thermally-broken aluminum framed curtain wall system, it was shown that double glazing with soft low-e coating, argon gas, thick-walled plastic spacer and triple glazing with thick-walled plastic spacer could meet the design criteria.

The IIS(Internal Insulation System) is applied in most Korean apartment buildings which are the most common type of residential buildings. Consequently, there are many cases in which the layer of insulation is disconnected by the structural components at the wall-slab and wall-wall joints in the envelope. These joints become thermal bridges where the risk of heat loss increases. It is expected that the EIFS(External Insulation and Finish System) is the solution to this problem. In this study, annual heating and cooling loads of apartment buildings with IIS and EIFS were compared using DesignBuilder program in order to evaluate the thermal storage effect of EIFS where the concrete thermal mass is located inside of the insulation material. As results, the apartment building with EIFS could reduce annual heating and cooling loads by 2.4% and 4.1%, respectively.

Many countries are making nationwide efforts to reduce the energy consumption which causes greenhouse gas emissions and global warming problems. Energy performance assessments and certification systems have been in force to save energy consumption of residential buildings, and are anticipated to have strong effects through the systems. The domestic Building Energy efficiency Rating System is in its early stages and is considered that the additional update is needed for the enlargement of energy saving effects. Thus, in this study, the operation and assessment methods of the domestic Building Energy Efficiency Rating System and the British EPB Regulations were analyzed and compared. The strengths and shortcomings of two systems were analyzed and a way of improving Korea’s relevant system was developed. In addition, the appropriate direction for Korea to take in this regard was deduced.

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 (9.92㎾ and 18.51㎾), respectively, and average heating and humidifying effects in Nov. are 8.7℃ and 0.7gw/kgda (19.50㎾ and 3.89㎾), respectively. Total outdoor air sensible and latent, cooling and heating load was found to be reduced by 38.8% through the thermal labyrinth system.

The purpose of this study is to draw a direction of improvement for Building Energy Efficiency Rating System through the comparison and analysis of foreign systems. Domestic Building Energy Efficiency Rating System and two foreign systems which have the similar limit of application with domestic one, HERS(Home Energy Rating System) and SAP(Standard Assessment Procedure)2005 were selected. In order to carry out the study, each system was surveyed and then the evaluating method for building energy performance was compared and analyzed. As results, we suggested the direction to make domestic Building Energy Efficiency Rating System better.

Energy performance assessments and certification systems have been in force to save energy consumption of residential buildings, and are anticipated to have strong effects through the systems. Korean Building Energy Efficiency Rating System is in its early stages and is considered that the additional upgrade is needed for the accurate assessment. Thus, in this study, the assessment methods of the Building Energy Efficiency Rating System of Korea and the SAP2005 of UK were compared and energy requirements of an actual residential building were calculated with two assessment methods, respectively. The strengths and shortcomings of two systems were analyzed and a way of improving Korean system was suggested.
