The organization and standards you are looking for are:

BICSI  - and TIA/EIA 568 et al for structured 
cabling design for low voltage distribution.

The BICSI organization has training and certification for RCDD 
Registered Communications Distribution Designer

A BICSI article that is on there web site about data center design is

TIA/EIA 568(ab) how ever many they are up to discuss structured cabling 
design for UTP/STP/fiber/coax including patch cables single and multi 
pair UTP/STP/fiber  patch panels,  HVAC control, fire system control and 
security systems.
