I can't speak to what others have done / are doing, but there's movement within the general "building science" community to improve the documentation around home systems. As more technical devices get added to homes' mechanical systems (PoE, ERVs, whole-home dehumidifiers), it's important that new owners (or even you, as current owner!) have access to an operating manual for the home. Maintenance procedures and schedules, numbers for service technicians, general operating instructions and troubleshooting, etc.

(Of course my mind goes to "maybe there's a SaaS opportunity here?", but I suspect that if it's difficult to get people to even gather documentation about maintaining their home's systems, it'll be even more tricky to get people to pay for it.)

On the "building science" side, do you know any search terms or group names that might help me find out more?

It makes sense! The industry went from no-HVAC, to locally-controlled HVAC, to the modern (solar, networked HVAC, data network, IoT) era in the span of about 50 years.
