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. The sejoints 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 Design Builder 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.

Greenhouse gases and global warming problems arose as a global issue. Reducing heat loss through building envelope can save significant amount of energy used in buildings. Internal Insulation system is usually applied to the apartment in Korea. In this case, the layer of insulation is disconnected by structural components at the joints of wall-slab and wall-wall. These joints become thermal bridges at which the risk of inside surface condensation and heat loss increase. In this study, linear thermal transmittance of typical thermal bridges in apartment building envelope was evaluated in case of applying internal insulation system(existing case) and external insulation system which can be a solution for eliminating thermal bridges.

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.

Many countries are making nationwide efforts to reduce the energy consumption which causes greenhouse gas emissions and global warming problems. Buildings are responsible for over 24% of the energy consumption in Korea, and 68% of the total energy consumption in the building sector comes from residential use. Various systems such as Energy-efficient Building Design Standard, Green Building Certification System, etc. have been in force to reduce the energy consumption of residential buildings, and Building Energy Efficiency Rating System is one of them. Korean Building Energy Efficiency Rating System is in its early stage and leaves room for additional improvement for the effective operation and accurate assessment. In this study, the Building Energy Efficiency Rating System of Korea and the SAP2005 of the UK were compared and actual residential building's energy consumption was assessed by each system. As results, the merits and shortcomings of two systems were analyzed and a number of ways of improving Korean system were suggested.

Heat losses through thermal bridges are included for the apartment building's annual heating load calculation by the linear thermal transmittances. As results, apartment building with EIFS showed the 8.4% less annual heating load.

The IIS(Internal Insulation System) is typically 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. In particular, the amount of heat loss is significant at the wall-slab joints adjacent to hot water heating pipes. It is expected that the EIFS(External Insulation and Finish System) is the solution to this problem. In this study, annual heating loads of apartment buildings with IIS and EIFS were compared using the steady-state method. Heat losses through thermal bridges are included for the apartment building's annual heating load calculation by the linear thermal transmittances. As results, the EIFS could improve linear thermal transmittances by 65.1∼86.4% compared to the IIS. In addition, apartment building with EIFS showed the 8.5% less annual heating load.
