By : Bara Thaher Mohammad Sameer Osama Joma’a Supervisor : Dr Sameh Mona Climate Responsive Design For Administrative Building In different climate zones in Palestine An-Najah National University Faculty of Engineering Building department * * Project description Methodology for solutions Project design( Architectural , environmental , Structural , Mechanical, Electrical) Recommendations for selection of environmental elements according to climate differences Outline: Our project is a redesign and suggestion of administrative building. These type of buildings are important as it is used in many fields of usage in different climate zones such as . The building designers establish these type of buildings without an overview to climate differences. Project description Why administrative buildings: The employers of these type of buildings are not responsible for the energy bill, so they switch on the mechanical systems to reach their comfort zone. This will cost the government a lot of expenses. Project description (cont.) Why administrative buildings: We considered education and higher education building in Tulkarm. Project description (cont.) Four floors and ground floor building and 256 m² for each floor. East west orientation , and the entrance form east elevation . Project description (cont.) Orientation of the building east-west. solar design is not taken into consideration. Consumes a large amount of energy because there is a huge amount of air conditioners Project problems Project description (cont.) The east elevation contain large glassing areas. number of elevators is small compared to the size of the building. There are no emergency staircase. No shading. The parking capacity is not enough. Project problems (cont.) we have divided building solutions into three categories to compare. Category 1: existed building in Tulkarm. Category 2: suggested solutions for the existed building in Tulkarm. Category 3: the effect of climate diversity on the building. Methodology for solutions. Project design : Architectural solutions East elevation. Project design : Architectural solutions (cont.) West elevation. Project design : Architectural solutions (cont.) North elevation. Project design : Architectural solutions (cont.) South elevation. Project design : Architectural solutions (cont.) We used ECOTICT simulation program to analyze: Day lighting levels. Thermal insulation. We take a room in each elevation in existed and suggested buildings to be analyzed. Project design : Environmental analyzing.

Project design : Environmental analyzing (cont.) we redesigned the existing building in Tulkarm according to the followings: The American Concrete Institute code ACI 318-05. The seismic design according to UBC-97. The analysis and design were done using SAP2000 program. Project design : Structural Analysis and Design Design data : 1. Compressive strength : f\c =24 Mpa 2.Yielding strength of steel The yield strength of steel for flexure Fy= 420Mpa. 3. Bearing capacity of soil the bearing capacity of soil Qall.= 20Mpa. 4. Slab thickness One way ribbed slab is selected in design. The longest span (one end continues) = 4.55 m. The thickness of slab (h) = 455/18.5=24.6 cm we used 25 cm as a thickness of slab.
