Local climatic data and their impact on construction and urban design

Abstract

The basic aim of this research is to know the extent local climatic effect in Diala Governorate on the process of designing the residenrial unit. The descriptive method is used to achiere the aim of the research .The resulys of the research are : 1. At first grade the solar radiation effects the process of designing the residental unit and its ratio is 0.52 out of the effected climatic elements . This is through sharpness , length and duration . 2. The temperatune Comes at the second grade of the effect of the positive temperature parallel dduring the yrear ; its ratio is 0.35. 3. The air flow comes thirdly in its importance and its ratio is 0.10. 4. The elements of the climatelogy ( Humidity and evaporation have limited effect and their ratio is %03.)
