I have a 1600 sq. ft. warehouse with 3 solid walls and one wall that has two doors. Getting air to circulate in the space is nearly impossible. I have a plan but wanted to see if it was a good idea first. I have 5 skylights that extend up from the roof of the warehouse. They are about 2 ft. x 4ft and extend up about 2ft. at the tall end. There are two at the back, one in the middle and two at the front. I can't cut holes in the roof because it's a membrane roof and the homeowner's policy is very specific about it. However, if I cut holes in the highest part of my skylights and mounted exhaust fans, I should be able to circulate the air pretty easily. Not only that but for more than half of the year so far, the temperature outside our loft has been lower than inside our loft. Often, we are running the AC unit when opening a window (which we don't have) would suffice. By placing exhaust fans in the rear skylights, I think we can effectively draw air in from the doors. This could save us a ton of money and help avoid all of the noise that accompanies our 5 ton AC with too small ducts. Will this work and if so, where can I get some decent, inexpensive exhaust fans for my skylights. Probably between 10 and 18 inches. Any other considerations? Thanks in advance for any advice.

Hi there, i just bought myself an old house and I'm remodeling, I live in NJ and I bought those new LED lights that have snap springs that mounts on the sheetrock and comes with junction boxes that they claim are ic rated. My question is for the rough in part, do I need to make the connections to the box or can I leave the wires hanging in place and fish for them after? And don't know how the inspector would like to see it. Thanks in advance!
