I like how easy it is for different building systems to be integrated into one system. It's also nice how quickly the system responds to changes. The system can get very slow at times but it's not always our fault. There are some features we don't use that are still there. We'd like to have an option to turn off the notifications and alerts so that they're only used when we want them to be. Integration has been great! We are able to see all of our systems from one screen. The ability for VIA to connect seamlessly with other systems is one of its best features. I have not found anything yet that I dislike about the product. It has been very useful as we continue to implement our sustainability goals. We are able to track all aspects of our buildings operations from power usage to occupancy levels. This allows us to make informed decisions when managing our facilities. What was once a tedious task is now done automatically through VIA's integration into our systems.
