Abstract :

Nowadays, by applying new methods, a high percentage of fuel can be reduced to provide adequate heating or cooling for rural and urban buildings. These methods are still under study and should be reduced to 50% with accurate calculations by carefully examining them and applying new ways to reduce excessive energy consumption in urban and rural buildings. The objective of this paper is to estimate the annual cooling and heating amount (HDD and CDD) in comparing the need of Anzali city gas consumption with its estimated cost. The research method uses the calculation of the warm and cold days by Dr. Khalili's inventive formula, which is possible by using calculated cooling and heating rate. The instrument of this meteorological data and its proposed formula were used during a 34 year period (1979-2013) of Anzali station temperature. The results of this study showed that the need for the heating day is 1546.42° -day and the degree-cooling day is 94.55°, and the need for heating energy for a residential building with 100 m² and 2.7 meters height is 15657300 Rials and in the heating season it is 957.3 Rials.  The results of this research can help local and regional planners in relation to the actual cost of gas consumption and the zoning of its coefficient.
