The present study proposes improvement directions for responding to small buildings when revising the G-SEED (Green Standard for Energy and Environmental Design) in the future through the analysis of the system and current status of certification standards for small housing. G-SEED, the small housing standard, was introduced in 2012. However, the certification standards for small buildings are not separately operated. As such, standards for small housing are regulated in terms of certification days, review personnel, reviews, fees, and items. To analyze the difficulties encountered with small housing standards, the present study compared the scores of certified small and general buildings. As a result of comparing certification items, 9 items out of 20 items for small housing are the same, 8 items are easy, 1 item is difficult, and 2 items are evaluated only in small housing. For comparison of certification acquisition scores, buildings certified as general housing were converted into small housing standard scores and compared. The present study noted that in terms of certification acquisition scores, the average score for small housing was 60.78 points, which was approximately 4.6 points higher than that for general housing. However, buildings that scored high in general housing were downgraded. Next, directions for the regulation of small buildings in the G-SEED were reviewed. It is to operate certification items without classification of use by integrating the existing use classification system. At this time, the certification items can be diversified and differentiated within the items. Furthermore, adjustments to the level of difficulty of certification items for small building use are essential. To reflect small buildings in the G-SEED, the most important adjustments to system operation include introducing guidelines for the use and characteristics of small buildings, clarifying the certification audit documents, and simplifying the process of certification.
