As far as posting threads on hvactalk this is my first time, but been visiting this site off and on now for 5 years and this is a wonderful place to be. My profession has mostly been involved with working with all professional tradesman in the building maintenance and building science arenas. My current position in a datacenter based in Hawaii is pretty straight forward as the weather here is a constant 78 degrees (give or take a few degrees). No heat recovery, economizers, outside air, etc I surely miss the extreme weather changes, which I think, keeps a mechanic well versed in all aspect of a buildings operation.
Have fun and be safe
