That would be an interesting read. I have a pretty simple Python script controlling a Z-Wave thermostat that I'm pretty satisfied with. I've been curious about how much more efficient I could make it with a PID scheme, with my suspicion being "probably not too much more".

Its been 4 years since I've seriously cracked that stuff open, so I can't find any of the research papers we looked at. A quick internet search brought me to this page though: http://ilsagfiles.org/SAG_files/Meeting_Materials/2015/6-23-15_Meeting/CLEAResult_Smart_Thermostat_WhitePaper_20150505.pdf http://ilsagfiles.org/SAG_files/Meeting_Materials/2015/6-23-... To say they "did nothing" isn't to say they weren't better; to have someone constantly controlling your thermostat can be beneficial, but a smart thermostat over a programmable one did " 6.55% on heating and 0.95% on cooling over a programmable thermostat baseline" in terms of savings.
