Time for some technical questions
The basement floor is poured and the HVAC is in. Soon they will hang drywall. The plan is to enclose everything we can, so that all the runs for electric, compressed air, lighting and HVAC are hidden. Time is upon me to figure out some engineering details, and of course the input of VAF's brightest minds is of the essence.
The 60x40 foot maw you see here will become a lounge, mechanical room, closets, and workshop. The shop floorspace will measure roughly 36x40. Should be large enough; we build RV's in one car garages if we have to, right?
Ceiling height is between 8 and 10 feet, varying with the plenum build-outs for the HVAC duct and DWV plumbing.
I've tried to use the online lighting layout apps. Some don't play well with OS-X. After much web browsing, I believe I'm looking for about 100,000 total lumens well-distributed from multiple luminaries (between 50 and 80!) at a color temp of 5000K. I intend to go the LED route. Lorri despises fluorescent lighting and I want her to feel as at home as possible down here. With the homeowners insurance stroking the checks up to the policy limit, cost is not a primary concern (probably the only time in my life I will ever get to say that.) Ceiling will be white drywall, walls white or light beige drywall, and floor a light color epoxy (color suggestions welcome; I know- no flakes, so I can find my dropped rivets). If JonJay or any of the other lighting experts could give me a quick and dirty estimate of luminary quantity, spacing, and intensity, it would put me way ahead in the acquisition process.
Regarding electrical, we are just going to locate outlets everywhere, including a 220 for welder, etc. I'll include an overhead reel cord close to the center of the shop.
The space is well-insulated and will have its own ductless split HVAC unit.
The plan is to locate the compressor at the far end of the garage, about 75 feet from the center of the shop, indoors, but well away from all living space. My HVAC sub has bid the air lines as part of his total package with the modular home people, and he intends to run 1" black iron pipe into the shop and tee 3/4" from there, giving me a center overhead reel air drop and one on each of two opposite exterior walls, plus an outside air drop for spray painting in the driveway. My question is whether this material is a good choice vs copper or the plastic jacketed aluminum pipe I installed just before the fire happened (RapidAir 3/4" kit). Will rust contamination be an issue? The piping run from the compressor will go up, across and down to eliminate condensation trapping as much as possible. A remote power feed will allow the compressor to be turned on and off from inside the shop.
Thanks for any ideas anyone wants to throw out there. My research on these topics is anything but exhaustive, and I want to do this right - without overthinking it.
