How to conduct sunshine analysis in Tianzheng Construction 2014

Use Tianzheng to open the drawing that needs to calculate the sunshine. And copy the building separately, or create a new CAD file. The advantage of this is that it will not affect the operation of the soft armor when a large amount of calculations are required. It is best to keep the building markings (number of floors, height, etc.) to save the need to go back and review them.
Enter the building height. Find "Others-Sunshine Analysis-Building Height" in the toolbar on the left side of Tianzheng. The prerequisite for this step is that there must be a building outline and it must be a closed polyline. When entering the building height, you must first determine whether your drawing is in meters or millimeters. When entering the base elevation, pay attention to whether there is a height difference in the base. If not, enter "0".
After the building height is input, Tianzheng will automatically generate a "TG_SUNBUILD" layer, with the default color being blue.
Preparation for analysis. After entering the building height, you can perform sunlight analysis, but there are still some preliminary preparations. After selecting "Multi-Point Analysis", you will be prompted to "Select Occupants", that is, select the building to be analyzed for sunlight and the surrounding buildings that affect it (if there is an existing building nearby, you also need to enter its building height).
Analysis settings. After selecting the occlusion, a dialog box pops up, asking to set up the sunlight analysis. Taking Wuhan City as an example, select the location - Wuhan City. "Wuhan City Construction Project Planning and Management Technical Regulations" stipulates that the effective calculation time is from 8:00 to 16:00 on the Great Cold Day.
Start analyzing. After clicking OK, select the required calculation range, and the sunshine analysis will begin. The progress of the calculation is displayed in the lower left corner of the screen.
The calculation is completed. Generally, it will display 0-8, a total of nine colored numbers, each color represents a different sunshine time.
Check the sunlight conditions. According to the requirements in the "Regulations", different building shapes have different sunshine time requirements. Judging from the calculation results, the sunshine hours for the main bedrooms of the two buildings in the northeast are 0 hours and 1 hour respectively. If the requirements of the regulations are not met, the building location or the height of the building that blocks it needs to be adjusted.
Adjust building height or position. This step needs to be calculated by yourself based on your own experience, and may be calculated and modified repeatedly.
Finish. Through constant modifications and calculations, the sunshine specifications were finally met (the indicators must be carefully controlled).
