I work for SRP in Arizona, we have 17 buildings and currently use Metasys PMI and Extended Architecture for our front end. We have some pnuematics, ASI VAV's, and 99% JCI end controllers. Management is trying to spend some $$$ and get us into the 20th century (pun intended), we have spent big bucks on a survey but I feel the contractor had an agenda from the beginning since he is also a vendor. We are getting steered towards Tridium systems. Has anyone here replaced Metasys with another controls system?
