printer rooms in tenant scope of work

This isn't the first case where the Reference Guide and the Credit Form in LEED online contradict one another. My first line of defense would be to send a technical inquiry specific to the credit to GBCI and have them acknowledge the difference and to confirm if the legal language is required for credit compliance (more so than the recommendation to include in the Tenant Guidelines). Most tenants won't have copiers and printers that are high volume enough to require placement in a separate room with negative pressure and exhaust, though some might. We recently completed a LEED CS building that included reference in the lease to a "LEED Tenant Directive" for all tenants. In this we addressed design issues for all tenants that affected the base building - i.e. all tenants were required to reduce LPD by 15% at a min, all tenants were required to recycle construction waste, and meet all EQc4 requirements, among a few others. The directive laid out the specific design requirements as well as the process by which the owner/property manager would check the inclusion during design reviews. The LEED directive and the Tenant Guidelines were linked documents. So the owner was able to require certain LEED specific design items by reference to the LEED directive in the lease, without the wording actually showing up in the lease itself. The wording for an item such as this could be to the effect of "in the event the tenant requires a separated high-volume copy area X Y Z ventilation requirements must be met in accordance with LEED CS 2009 EQc5 requirements." Good luck!
