I am working with a convention center currently certified Silver in the v2009 EBOM rating system. The owners are monitoring data with the goal to re-certify when the time comes. They are currently undergoing a kitchen remodeling and are going to install all new equipment and change the layout. My question is the following: will they need to perform commissioning on the kitchen once complete? I am not sure whether the kitchen equipment should be considered a "system" or just individual pieces of equipment with manufacturers specifications.

Would the fact that they have a new hood or makeup air units be relevant to understand?

Thanks!
