Best Orientation Determination of Buildings in Zanjan City Based on Solar Radiation
Authors
Abstract:
In recent years, high consumption of energy has become one of the major problems of world, especially in big cities. One of the solutions given for this situation is using solar energy as much as possible. If buildings are constructed in accordance with solar radiation and regional climate, they can absorb the lowest energy in hot and the most energy in cold periods; there will then be noticeable saving in energy consumption. Since Zanjan has special location, the buildings’ orientation should be in a way that the most possible energy could be absorbed by the building through the cold periods, and the lowest amount of energy would be able to hit the building in hot periods. In this research, to reach the most efficient use of solar energy in Zanjan, as the case study of research, first the climate information of 40 years timing was collected from Zanjan Synoptic Center, and the orientation and height of sun was extracted afterwards by using Q-BASIC software. The amount of solar radiation on vertical surfaces of walls in various angles was calculated using law of cosines. And finally the best orientation for buildings in this city has been determined. The results of this research showed that vertical surfaces with the orientations of +150 and -150 south-west absorb the most amount of energy, and the surfaces with orientations of +15 and -15 north-east and west absorb the lowest energy in cold and hot months of the year. The highest difference of radiated energy in vertical surfaces is at +135 south - east and – 135 southwest through hot and cold periods. According to the research results, the best settlement orientations for buildings are 135 degree and 225 degree of Azimuth angle.

The Possibility of using Flat Plate Solar Collector Based on the Best Calculated Tilt Angle in the City of Rasht as a Case Study (TECHNICAL NOTE)
The possibility of using flat plate collector in northern parts of Iran specially city of Rasht has been investigated in this paper. According to the high humidity in the northern parts of this country, diffuse radiation plays a more important role than direct radiation. This fact can change the results of delivered solar energy and the best tilt angle of the collector compared to the sunny cen...
