Another nice tool: Maybe you could borrow a FLIR camera. That would show 
every ever so slight hot spot in a room, like something that consumes a 
couple of watts of standby power but has long since been forgotten.

Tried to load your layout but got an error and I could not find any 
pointers via web search.

Error parsing file ...

Then again this is the first time I tried PCB Designer on Ubuntu in 
VirtualBox. Maybe some settings are messed up.

WRT to energy savings, if you find some gizmo that consumes next to 
nothing but has to run and its transformer gobbles up 95%+ you could try 
to replace i.e. a 115V-12V transformer with a 230V-24V. "Modern" 
transformers are often operated a hair below or right at the onset of 
saturation.
