If you have an older building with no lighting controls and are either wanting to upgrade your lighting controls, or are wanting to reduce your energy consumption, then the Lutron Vive product is a great way to accomplish that goal without spending a mini fortune to rewire your entire building. The Vive product is specifically designed for commercial retrofit applications and with its combinations of wireless hubs, remotes, plug controllers, occupancy and daylight sensors you can achieve a retrofit on a budget you might never have thought possible.
Also, if you are being required to upgrade all of part of your building to comply with the latest California Title 24 requirements, then the Vive product might be just what your looking for.
