GREEN GLOBES #5.3.1 Are there designated storage areas for hazardous materials/janitorial supplies with full-height, floor-to-floor walls and mechanical ventilation?
- Yes (10 points)
- No (0 points)
Mark “N/A” if there are no janitorial storage areas dedicated to the project space and/or they are centralized and not under control of the tenants.
Janitorial rooms or closets typically contain cleaning products that have strong, corrosive fumes. In order to maintain good indoor air quality in the building, these spaces should be negatively pressurized via exhaust systems. Also, full-height walls should be installed to prevent any odors or airborne contaminants from crossing into other spaces via the ceiling cavity. If flammable materials are to be kept in this room, the doors and wall should be fire-rated and the outlets should be fire dampered.
Construction documents should note storage rooms with cleaning supplies, partition type, and show that the room will be negatively pressurized with an exhaust rate as required by code or 50 CFM, whichever is more stringent. The make-up air can be either directly supplied into the room or via transfer air from a grille or undercut door. There should be no return from this area.
