With the considerable increase in building energy consumption, a green building rating system and certification are required to reduce building energy consumption and CO2 emissions. Among various building energy codes and regulations, LEED 2009 was selected because it is the most widely used system worldwide (currently used in around 42 countries). In order to evaluate the building energy efficiency, we focused on the criterion “EA Credit 1. Optimize Energy Performance”. Moreover, the Korea Green Building Rating System was also evaluated to compare each criterion. Using the eQUEST program, typical and hypothetical office buildings with various glass types and window sizes were simulated for four cities in South Korea (Inchon, Kangnung, Kwangju, and Ulsan). The comparative analysis indicated that Inchon had higher annual energy consumption and energy conservation than the other three cities. With an increase in the window size, the energy consumption increased considerably with the use of non-insulated glazing (G1, G2). However, with the use of high-insulated glazing (G6 and G7), the consumption decreased slightly when a larger window size was selected. In particular, with the window size over 60%, 20.4~28.1% energy was conserved in Inchon, and around 17~25.5% was conserved in the other locations. Finally, we compared the achievable points in two building energy efficiency criteria; LEED 2009 and Korea Green Building Rating System. The comparison indicated that the criteria for the former were much stricter than those for the latter. Although around 75~79 Mcal/m2 (12% of minimum energy saving) is required to earn one point in LEED 2009, 130 Mcal/m2 of energy consumption can earn maximum points (15 points) in the Korea Green Building Rating System. Therefore, stricter regulations are required in the next major amendment for “Building energy consumption regulation” in the Korea Green Building Rating System. We hope that this comparison and analysis of two building energy efficiency criteria will lead to the formulation of stricter building energy regulations and in turn, ensure optimum fenestration design and glazing types for energy conservation and green building certification.
