Energy and Environmentally Efficient Architectural Model Using Native and Adopted Strategies for Lyari Hospital

Abstract

The healthcare industry is becoming a model for the larger world in developing an ecological environment; medicine approach is: “first do no harm”. Developing new hospital campus in urban site; ideas of therapeutic architecture based on ASHRAE recommendations of sustainable site planning principles. For the energy and environmentally efficient architectural model for the design of Lyari hospital, we developed a series of models using native and adopted architectural strategies. The environmentally efficient master plan will form design decisions so that the foot print of the proposed development does not overwhelm the capacity of the site. The climate of Karachi has additional challenge of humidity control, compared to rest of the cities in Pakistan due to the proximity of sea. For all code and standards defined in climate consultant, the comfort zone of winter and summer temperature range lies between 20oC and 31oC respectively. The traditional passive architectural strategies are still most popular in designing the climatic responsive buildings for Karachi. The Double skin façade building presented a model of the envelop for Karachi which was simulated to be 87% more efficient from energy conservation perspective then vice versa
