I was wondering if anyone has had any experience with return registers for log cabin homes. I am GEN.Con. in the Sierra mountains doing corrections on my plans. I have a home that is 1955 sq ft. There is a Great room with a vaulted ceiling, down stairs master bdrm, a loft and 2 upstair rooms. I have logs up to 8.5' which then will turn into 2x6 stud walls for the 2nd floor. I dont have to many options that I can see about placement for my return. I want to keep it away from the supply registers, but the heater will be in the garage and the furthest area is the master bedroom. I have one place that I can come up from underneath the main floor,(which is a Crawlspace) it would be where the stairs will be up to the 2nd floor. I would like to have a return upstairs, but can't figure out how to get it there and if I do put it downstairs I think I have to put it where the stairs will be since they will be enclosed. Any suggestions, I am also having to follow Title 24 for all of this. Thanks for any replys.
