Abstract

Estimation of energy needed for heating or cooling buildings during cold or warm season, is one of the most important parameters in architectural designs. This energy is a function of climatic values named heating (HDD) or cooling (CDD) degree-days .In this study, as a first step, a computational model is developed which calculates daily values of HDD and CDD based on mean monthly air temperatures, for a network of 218 stations .In the second step, the spatial distribution of HDD and CDD was analyzed by multiple regression method. Based on the equations obtained, the HDD and CDD at each point of country could be estimated. In the next step, considering some thresholds for HDD, the 7 climatic groups from H1 (Mild) to H7 (Extra cold), were identified. With similar method the regions were divided into 5 groups as function of their COOLING DEGREE-DAYS need, from C1(mild) to c5 very warm . In addition, four humidity groups were added to the classification system. As a result the proposed classification, was defined by general formula of HiCjRk where i, j and k (only for costal zones) vary from 1 to 7, 1 to 5 and 1 to 4, respectively. Finally, based on criteria of classification, the CLIMATIC CLASSIFICATION map of IRAN with the 1:1000000 scales at GIS media was provided.
