Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

In Korea, it is necessary to improve the performance of buildings with respect to the energy efficiency while improving the quality of occupants' lives through a sustainable built environment. During the design and development process, building projects must have a comprehensive, integrated perspective that seeks to reduce heating, cooling and lighting loads through climate-responsive designs. The aim of this study is to assess the optimal window-to-wall ratio of multi-rise residential units in the early design phase in Korea. The study analyzed the variation of annual heating and cooling energy load in two apartment prototype units located in Seoul city using different WWRs. The analysis was conducted using Autodesk Ecotect Analysis 2011 tool. The study found for total annual building load reductions WWR on the south and north face should be studied independently based on the room function. It also found reducing the WWR for bedrooms and windows on the northern façade resulted in reduced total annual building load.

It is necessary to improve the performance of buildings with respect to the energy efficiency while improving the quality of occupants' lives through a sustainable built environment. During the design and development process, building projects must have a comprehensive, integrated perspective that seeks to reduce heating, cooling and lighting loads through climate-responsive designs. The aim of this study is to find an optimal thermal transmittance (U-values) for building envelope elements for low energy multi-rise residential buildings in the early design phase in Korea. The study found that using small U-values of $0.15w/m^2K$ for exterior walls, ceilings and floors and $1.0w/m^2K$ for south and north facing windows has resulted in energy reduction of 22.1%-59.4% in the south facing rooms and 43%-77.6% of the north facing rooms. It has also found the energy load reduction potential of using small U-values are higher on the north facing rooms. The findings of this study can be suggested to be used as a baseline case for low energy consumption studies. It can also be used to determine appropriate envelope materials and insulation values.

A vertical city with multifunctional land use turns out to be the most viable solution for an urban condition characterized by increasing density due to population expansion, topographical limitation of buildable land, economic development and the pursuit for collective sustainable living, such as in Hong Kong. This paper presents initial research results from a study on the chronological and typological evolution of tall buildings in the city, from the climate-responsive verandah typology to the mixed-use hyper-commercial podium and residential tower typologies that predominate today, to the ultimate formation of a vertical city. Case studies and surveys have focused on the development of this building typology throughout the decades since the 1920s, substantiating a discussion on the subjective and objective factors contributing to a genesis of the vertical city phenomenon in Hong Kong. The discussion will engage, under the notion of the vertical city, on how residents and visitors adapt to the growing density of the city, and how they accustom themselves to the changing urban morphology over time. Advantages such as high efficiency, spaces savings, time convenience, etc.; and disadvantages such as deficiency in livability, incompatibility of uses, environmental health deficiencies, etc.; serve as a reference for other cities in need of high-density planning due to population and economic growth.

경관과 정원은 현대 도시에서 중요한 실천 매체로 부각되었다. 이 중 본 논문에서는 정원을 프레임으로 도시를 살펴본다. 정원은 도시민의 활동 매체로 재설정되고 있으며, 도시 재생과 도시형 마을 만들기의 중요한 실행 주제가 되었기 때문이다. 이런 입장에서 본 논문은 정원을 매개로 나타나는 도시 구조와 도시민의 행태, 그 과정 및 결과에 집중하여 볼 때 현시대 우리에게 적합한 조경이론으로 "통합적 정원도시론"을 검토하고 제안한다. 이것은 한 세기 넘도록 진화해온 조경을 되돌아보며, 조경의 정체성을 되묻는 과정이자 결과이기도 하다. 먼저 정원과 도시 사이에서 조경의 씨앗을 품어둔 바 있는 에벤에저 하워드(Ebenezer Howard)와 프레드릭 로 옴스테드(Frederick Law Olmsted)의 입장이 크게 다르지 않았음에 주목하며 '작동하는 경관과 감응하는 풍경'이 도시의 기본적 요소이자 조경이론의 시작이었음을 정원도시론을 통해 살펴보았다. 또한 지난 세기를 지나며 그들의 이상이 도시에 모두 구현되지는 못하였으나, 현재는 동아시아 도시에서 전통 정원문화에 기반한 정원의 원형이 형성되고 있음을 살펴보고, 그에 대응하는 조경이론의 진화 방향을 살펴보았다. 결론은 새로운 버전의 정원 개념은 우리 도시에서 생활 인프라로 재설정되어야 한다는 것과 그것이 작동하기 위한 새로운 정원도시론이 필요하다는 것이다. 이를 위해 각 장별로 다음과 같이 세 가지 논점을 검토하였다. 첫째, 현대 도시에서 나타나는 정원과 동아시아 정원문화의 가치는 공동체성(community)과 통합성(integrity)을 주제로 형상화되고 있다. 둘째, 아파트로 대표되는 한국적 공동체성은 가드닝(gardening)으로 표출되며 도시와 생활의 재결합과 그것을 지원해줄 전문분야로서 조경의 역할을 필요로 하고 있다. 셋째, 동양적 자연관에 기초한 도시 기반, 일상생활, 정원 매체, 즉 도시-생활-정원이 유기적인 실천론으로서 통합적 정원도시론을 검토하고 고민해 본다. 결과적으로 현대의 정원과 도시는 동아시아 조경문화, 정원문화에서 아직 재발견이 필요한 중요한 요소와 가치들을 찾고 있음이 확인된다. 통합적 정원도시론의 제안이 조경의 지속을 담보할 수는 없겠지만, 이를 계기로 조경뿐만 아니라 도시와 관련한 모든 분야가 협업하며 정원도시를 고민하는 기회는 될 수 있다. 이를 통해 "대도시 또는 밀집 도시에 적합한 정원과 도시의 개념, 공동체성에 기반한 정원문화의 확산과 지원 방안, 생활방식과 지형조건에 적합한 조경이론/설계이론의 진화, 기후변화 대응이 가능한 지속가능한/회복탄력적인 정원도시론 모색, 그리고 21세기 조경의 새로운 역할 설정" 등이 본격적으로 고민되길 기대한다.
