I have a US client that is renting a space inside an existing factory to put in it his laundry facilities services. It's a part of a big warehouse, all a big environment, so it won't be possible to change much on the envelope, mainly on lighting system. There is a system of wall fan on one side that sucks air in from outside and on the other side a water chilling system.
Do my client need to comply with this prerequisite? How?
