Sun Capture, Carr's Hill Field at 3 PM

Sun Capture, Carr’s Hill Field at 3 PM

Follow-up Question Answers:

a. On March 21st, Carr’s Hill Field receives about 9.5 hours of sunlight from 7:30 a.m. to 5:00 p.m.

b. The sun first strikes this site at 9:30 a.m. on December 21st and 5:50 a.m. on June 21st.

c. July 1st is the day of the year with the most sunlight on my site -with a whopping 13 hours!

d. The sun on August 15th has an altitude of 45 degrees North and an azimuth of 249 degrees (from horizon level)

e. My site receives a heavy dosage of sunlight every day of the year (in varying amounts). To create a porch that is warm in the winter and cool in the summer would require a slant at an angle and height that blocks the high hot summer sun and allows in the low warm winter sun. So, a porch facing directly south (and at a slant to deflect the high summer sun) would stay warmer in the winter (from sunlight) and cooler in the summer (by blocking the hottest hours of sunlight).

f. For shading devices at Carr’s Hill Field, there is a lot of sunlight let onto the open field. So a flat awning would block most of the direct sunlight although facing a southerly direction (as stated in the previous question) would also aid in the cooling process.
