skylight 25x25, with 16 bronze tinted skylights. will be a cafeteria underneath for 10-15 people. 14 ft high walls. constant volume system.
With U=1.0 and SC=0.73 for a singele 1/4" coated skylight, the cooling load comes to ~ 10 tons (4500 cfm) with Trace 700.
What is good estimate of U-value, SC.
Is 4500 Cfm too high? total area is 600 sf. almost 8 cfm/sf? what is good tonnage estimate?
