BIM의 생산성과 효율성 때문에 건축설계 방식으로 BIM을 선택하는 건축가들이 증가하고 있다. 또한 건물의 에너지 사용량에 대한 인식 제고와 환경에 대한 관심이 높아지면서 빌딩에너지 코드의 필요성에 대한 요구가 증가하고 있다. 현재 많이 사용하고 있는 2D CAD 설계방식으로는 건물 외피 에너지코드를 검정하는데 많은 시간과 노력이 소요되며 디자인 변경에 다른 즉각적인 대응이 어렵다. 이 연구의 목적은 BIM을 통한 건물 외피 에너지 모델링의 효율성을 보여주는 데 있다. 우리는 BIM을 통해 설계과정에서 디자인 변경에 따른 정보 값을 누락이나 재계산 과정 없이 동시에 산출할 수 있기 때문에 건물 외피 에너지코드 검증에서 생산성과 효율성을 높이는 데 기여할 수 있다. 연구의 절차는 다음과 같다. Revit 2011으로 만든 the Goldin at Essex Crossing 공동주택의 BIM을 사례 모델로 하여, 뉴욕시의 에너지 코드에 부합하기 위한 에너지 계획의 기준을 분석한다. Revit 모델의 설정을 통해 나온 결과 값과 뉴욕시의 에너지코드에서 요구하는 기준 값을 비교한다. 최종적으로 미국 에너지국 (U.S. Department of Energy)에서 제공하는 에너지 검증 프로그램인 COMcheck에 데이터값을 입력하여 건물 외피 에너지 성능이 뉴욕시 에너지 코드에 부합하는 지 여부를 체크한다.

In Korea, Housing Performance Rating Indication System was first adopted in 2006. Main purpose of the System is on developing criteria which can systematically measure the level of housing performance. Among the five categories of Housing Performance Rating Indication System, Repair Convenience is closely related to Remodeling which has been widely recognized as an alternative to the building reconstruction. Especially, as the actual housing supply level in Korea is reaching almost 100%, it is crucial to expand Long-life Housing through the effective maintenance and management. In addition, consumers should have an access to the performance ratings of apartment buildings on which they can rely on in choosing their own housings. And for construction companies, a performance code enacted by government will provide them with a standard that they can utilize in determining performance level of buildings that they build. This study examines data which has been obtained from the recent application of Housing Performance Rating Indication System and Repair Convenience category is main concern. Findings from the study will provide vital information in improving current Housing Performance Rating Indication System.

Making of agreement with participation subjects is important process laying stress on presentation and a reasonable design guide line to form space order grant and synthetic space in Housing Complex plan. This study analyzed residing application specific character of design guide line that is presented to architects in general planning laying stress on plan only of 'Bongmu-dong town house' and design agreement of by architectural result that appear analyze. Result that analyze is as following: 1) Confer in 18 plan contents and integrate design or was adjusted. Being main conduct and unit plan and residing only in plan many negotiations accomplish. Architect who confer most Designs of 5 architects is 'Jean Michel Wilmott' and 'Shigeru Ban' 2) contents that confer much in plan main conduct and unit generation were details plan. Contents that is conferred with many architects are about door/core/rooftop be and asked a question about proper size of entrance. Negotiation about size was expose to the tribe of knowledge about element that do furniture and detail of necessary each space in life style of our country. We must present furnitures or detail element that appear by emotion of our country and detailed item of furnitures' size etc.. in guide line. It is immediate that creation of guide that architects can approach easily for lacking abroad architects of interests by code difference in each country is pressing. 3) In residing plan 4 architects of 5 architects applied similarly guide line in design. Most architects look by active support that make synthetic housing complex. and this is construed that act positively to make by unified residing. That plan of woods or landscape architecture and security of green area space are thing to approach on 'Environment-friendly mode of life residing only' that is general planning subject of 'Bongmu-dong town house'. 4) common question items of architects guide line of though is refered definitely when make out effective interests plan. So that can overcome legislation difference, countermeasure to make understood construction code of our country is pressing
