Question
a. Draw one diagram showing plan view (footprint) of the building and nearby obstacles, and others showing the profile (elevation) view and the relative heights of these obstacles.
b. suppose that your goal is to get the most out of radiation absorption in all seasons. Where would be the best place to put a solar collector and to what angle must the collector be adjusted for the solstices and equinox? Using the diagrams that you have drawn for (a), indicate how you would correct your solar collector for obstruction due to the presence of those obstacles.
The slope, aspect and albedo are three important variables upon which radiation budget depends. Calculate the rates of solar heating (SH) at solar noon on the equinox for the four surfaces using the equations.
