This study focused on changes in form and spatial uses of Urban Hanok in Bukchon, Seoul. There are 10 representative cases which have been renovated through the policy of 'Preservation & Regeneration of Bukchon' by Seoul metropolitan government and other experts. Changes in form and spatial uses of Urban Hanok in Buckon are as follows. First, Changes of scale. Trough removing extension parts, facade of renovated Hanoks are 'transformed' into recovering their identity. Using basements or lofts, intensive application of spaces is transformation which promotes the vitality of Hanoks. Second, changes of space organization. As Hanok changes its function from residence to commercial or cultural use, il a1so changes space character or reorganizes space organization. It is important that deciding function of Hanok has to adjust its scale and organization. Third, changes of construction performance. Through introducing new material and constructing method, performance of wall has been changed respecting its wooden structure and interior-exterior figure. However, technical studies must back it up not to destroy its value of eco-friendly architecture. Fourth, changes of facility systems, like floor heating system. They changes floor level of Hanok equally, and then sections of Hanok have became simple. Furthermore, inserting new facility space, such as boiler room, stand-up kitchen, bathroom and toilet, organization of space also changed. It is necessary that wise alternative proposal through the method of transformation or mutation must be presented. These four changes can be classification into method of 'transformation' and 'mutation'. Changes of scale are method of transformation and changes of space organization are method of mutation. Also, while changes of construction performance are mutation, changes of facility systems are transformation. Recently, as price of lots have been increased, a lot of Hanoks have been commercialized. Thc commercial energy threat 'the identity of Bukchon as residential area'. From now on, to operate 'identity' and 'vitality' complementary, it is necessary to make up for the preservation policy of Hanok and consolidate renovating standards of Hanok which correspond to character of particular region and building usage.

빌딩에서 발생하는 폐열을 활용할 목적으로 동절기 옥상정원에서 푸른 잔디를 유지하기 위한 잔디생육시험을 실시하였다. 옥상정원 지반에 Heating system을 설치하여 시기별 잔디생육상태를 조사한 결과는 다음과 같다. 겨울철 옥상녹화 지반을 heating처리한 결과, 무처리구에 비해 잔디품질 및 피복률이 우수하였으며, 잔디의 뿌리길이, 잔디밀도가 모두 상승하였다. 표면온도를 비교한 결과, heating지반의 온도는 평균 $10.9^{\circ}C$로 $0^{\circ}C$를 유지하였던 무처리 지반에 비해 월등히 높았으나, 수분함량은 평균 1.9% 낮아진 것은 $10.9^{\circ}C$로 유지된 지온으로 인해 수분증발이 계속 이루지는 것으로 사료되었다. 적설량이 15cm 이상 쌓인 상황에서, 히팅 시스템이 설치된 잔디밭에서는 4일만 눈이 완전히 녹았으나 대조구에서는 적설량의 변화가 거의 없었다. Heating system의 보일러 수온을 $55^{\circ}C$에서 $60^{\circ}C$로 높이자, 잔디는 건조 스트레스를 받아 잎끝이 마르는 증상이 나타났다. 앞으로 옥상정원에서의 잔디 재배과 관계된 세부적인 생리적 스트레스에 관한 연구가 필요하다고 판단된다.
