Sustainability became the keyword of our society worldwide, and it is undoubtful that buildings are mainly responsible for green house gas emission and energy consumption. Responding to current needs, US Green Building Council has launched the first LEED rating system in 1998. Since then, LEED has been evolved and it has multiple sub-system categorized by project types. This study aims to analyze characteristics of sustainable neighborhood development and to suggest methodology for establishing certification system in Korea. First, LEED-ND 2009(LEED for Neighborhood Development) was addressed with certified projects by US Green Building Council. After that, LEED-NC 2009(LEED for New Construction) was compared with green building certification criteria in Korea to find out unforeseen aspects by each system, in terms of sustainable neighborhood development. As a result of this study, sustainable neighborhood development requires a transition of architects' responsibility beyond building design. Building technology has been advanced at extremely fast pace, however, applying techniques to individual architecture would not make our town sustainable. This study provided basic resources to understand that creating sustainable neighborhood is social phenomenon and more studies should be undertaken to establish Green Neighborhood Certification Criteria in Korea.

The major purposes of this study were to analyze main features of US Green Building Council's LEED for Homes rating system and examine residents' satisfaction on their LEED-certified homes and neighborhoods. The first part of this article shows the structure and features of the LEED for Homes rating system and the process to obtain credits of this rating system. The investigation to assess residents' satisfaction targeted LEED certified home residents in Midwest in the United State. The satisfaction was assessed in relation to socio-demographic and housing characteristics. To collect data, a quantitative survey was administered to the residents of LEED-certified homes in Midwest in the US. A total of 605 surveys was sent out and 235 were collected, yielding a 38.8% response rate. Findings revealed that LEED-certified home residents were highly satisfied with their homes and neighborhood although neighborhood satisfaction was lower than housing satisfaction. Residents' income and education were the significant socio-demographic factors that show significant relationships with housing satisfaction. Residents' home ownership, length of residence, housing types were significant housing characteristics on their satisfaction while the levels of LEED certifications (i.e., certified, silver, gold, and platinum) were not significantly related to housing satisfaction. The findings of this study suggest the importance of developing effective strategies for those who are less educated, lower income classes, renters, or multi-attached housing residents for more successful development of LEED-certified homes in the future.

This study has been conducted to describe the establishment of national measures to reduce world energy consumption and $CO_2$ Emission. Particularly, Reductions in energy consumption from building operation is the most important part to achieve these national objectives. Element to evaluate the quantitative effects of these systems by having rationalized regulation and operation is essential, when planning for building energy reduction design. USGBC(US Green Building Council) have operated sustainable assessment method called LEED, which introduces baseline performance and evaluation direction for building simulation techniques. This research analyzed Quantitative assessments of the building energy consumption and analyzed baseline figures to provide comparative analysis with standard building settings.
