As old apartment buildings account for nearly 60% of residential buildings in Busan region, the necessity of green remodeling is increasing substantially in recent years. In this study, heating energy consumption with building age was investigated using real energy data obtained from K-APT database. Classifying apartment complexes into four groups (Group 1, 2, 3 and 4 which means the complex was completed in ’83~’89, ’90~’99, ’00~’09, and ’10~’17, respectively), heating energy consumption was estimated for the period from 2014 to 2019. The result showed that median values of heating energy consumption tend to increase as the building ages increase, regardless of heating degree days. To examine the effect of energy conservation measures for old apartments, energy simulations were conducted assuming the window replacement for Group 2 apartment, which accounts for most of the old apartment buildings. Simulation results showed that the window replacement led to the energy reduction by 19.3~47.8%, which corresponds to Group 4 or higher level of energy efficiency.
