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.

Project design : Environmental analyzing (cont.)
From the previous analysis, the output of ECOTICT program was as follow:

Thermal analysis
Using ECOTICT program, we analyzed the second floor in existed and suggested buildings, and extracted the simulation output.

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 Mpa2.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 cmwe used 25 cm as a thickness of slab.
