The fourth report is a detailed shading report that gives a plot of the shading pattern on the glass at a specific hour along with all other information concerning shaded and unshaded areas, angles, and solar loads. The final report is a shading analysis summary report that includes the same information as a detailed report except summarized over a specified time period. The many high resolution plots displayed on screen can be printed or written to disk in an AutoCad drawing file. Next, each shading device is gridded into similarly small rectangles, but additionally the coordinates to the center point of each rectangle are also computed. If a projected line is found to intersect the window, then the tiny rectangle where the intersection occurs is said to be shaded.
All input data is checked at the time of entry so that no improper data can be entered.
The general project data includes the project name and number, the project location with degrees latitude and longitude, ground reflectance, client information, and any general remarks. The glass material data includes specific information on the glass type, U-Factor, shading coefficient, and number of panes. The shading device input data not only allows you to define standard overhangs, fins, louvers, and awnings, but also devices of any conceivable shape and size. In fact, an adjacent building or even a tree can be defined as a shading device. Each glass section can have up to 10 different shading devices defined for it.
