Abstract

Population Increase and cities expansion caused increase in energy consumption and negative effects on climate temperature changes and on physical and mental health of cities residents as well. One of the effective solutions is preservation and development of urban forestry (green space) which can retrieve partly, these negative effects. In order to investigate the urban forestry economy effects (green space), 384 questionnaires were distributed among people and the data were analyzed, using SPSS software. The results indicate that urban forestry has useful effects on energy consumption. Based on calculated coefficient of determination (R2), 56% of variation of depended variable (Urban forestry or green space) can be predicted and determined by tree variables (turn on air conditioner time, maximum of energy consumption and energy cost in hot season). Finally, a mathematical correlation between urban forestry and economical factors was developed. The correlation showed that development of urban forestry (green space) decreased the various costs.
