H. FAN SYSTEMS & AIR ECONOMIZERS
2 Low-turndown single-zone VAV fan system must be capable of and configured to reduce airflow to 50 percent of
design airflow and use no more than 30 percent of the design wattage at that airflow. No more than 10 percent of the
design load served by the equipment shall have fixed loads.
3 Fan system allowance includes fan system base allowance.
4 Filter pressure loss can only be counted once per fan system.
5 Complex Fan System means a fan system that combines a single cabinet fan system with other supply fans, exhaust
fans, or both.
6 Computer room economizers must meet requirements of 140.9(a) and will be documented on the NRCC-PRC-E

J. VENTILATION AND INDOOR AIR QUALITY
This table is used to demonstrate compliance with mandatory ventilation requirements in 120.1 120.2(e)3B 140.4(p) and 140.4(q) for all nonresidential and hotel/motel and
d:t24refnolink/]160.2, 160.3(a)3D, 170.2(a)4N, 170.2(a)4O for high-rise residential occupancies. For alterations, only ventilation systems being altered within the scope of the permit
application need to be documented in this table. In lieu of this table, the required outdoor ventilation rates and airflows may be shown on the plans or the calculations can be presented
in a spreadsheet.
01 Check the box if the project is showing ventilation calculations on the plans, or attaching the calculations instead of completing this table.
02 Check this box if the project included Nonresidential, Hotel/Motel Spaces or Multifamily Common Use Spaces
03 Check the box if the project is using natural ventilation in any nonresidential or hotel/motel spaces to meet required ventilation rates per 120.1(c)2.
