I used to build smart homes with automation etc. I once ducted the waste heat from the server racks into the elevator shaft in the middle of the house to capture some heat in the winter with a vent to switch the exhaust outside in the summer (this was in Canada)

A home with a server rack? Sounds expensive. Pretty good idea though. I was thinking about our dryer vent and how to capture that wasted heat in the colder months.

The clientele I worked for typically spent anywhere from 2-20 million dollars on their homes with our contracts ranging anywhere from $50000 to a million for all the A/V, lighting control, security, surveillance, and full systems integration with HVAC and gates, garage doors, hot tubs, self playing pianos, etc. Whatever they wanted. This was the high end of home automation, mind you.
