Score Acquisition Status and Analysis of Land Use and Transportation in Green Building Certified Residential Buildings - Focusing on Certification Trends from 2017 to 2024 -

This study examines the score acquisition patterns of the Land Use and Transportation (LT) category in residential buildings certified under the Green Standard for Energy and Environmental Design (G-SEED) from 2017 to 2024.Using data from 3,018 preliminary certifications for new general and multifamily housing, the analysis investigates average scores, achievement rates, and zero-score distributions across LT assessment items.Results show that both building types consistently achieved high scores in accessibility to certification item 1.8 local amenities and proximity to certification item 1.6 public transportation, indicating that these items are well integrated into current residential planning practices.Conversely, certification item 1.4 validity of solar access protection measures recorded zero-score rates exceeding 95% in both categories due to the difficulty of meeting strengthened north-side maximum angle criteria.Differences between building types were also evident: while general housing frequently achieved high scores in ecological value of certification item 1.1 the existing site, multifamily housing showed notably higher zero-score rates for the same item, reflecting limitations inherent to large-scale site development.The findings provide empirical insight into the operational characteristics of the LT category within the post-2016 G-SEED framework and offer foundational data to support revisions aimed at improving the feasibility and applicability of LT-related assessment items in future residential projects.
