Can you meet the enhanced ventilation performance criteria by providing >30% ventilation for the building as a whole, even if you do not meet this performance for all zones/spaces?

Hello,

Hello.  We have documented Triple Bottom Line Analysis using Autocase for a Warehouse and Distribution Center.  The effort returned very interesting results in terms of values and particu

Proposed LEED project involves only a building addition in a campus setting where portion is served by new mechanical equipment and portion by existing building mechanical equipment.

For Option 1, the credit requirement refers to Section 1.2-5.1.6 and Section 1.2-5.1.6.2 in 2018 FGI Guidelines for Design & Construction of Hospitals.
