Floor area of building space covered by an indoor air quality (IAQ) management program that meets the criteria for this credit:
5,166,951 Square feet

A brief description of the institution’s indoor air quality program(s) (including information about regular auditing or monitoring, mechanisms for occupants to register complaints, and action plans):

Sac State uses Demand Control Ventilation on the majority of its building control systems, the campus can ensure a learning environment that requires the CO2 levels for the classrooms and offices to be maintained at less than 1000 PPM. When Sac State’s CO2 levels rise from the pre-designated set point, the controls automatically open the outside air dampers to introduce more fresh air and remove the CO2 content.
Sac State ensures proper CO2 levels as part of a preventative maintenance (PM) program which confirms correct equipment and filtering operation. The campus also uses HVAC systems with high efficiency filters rated at 85%. To ensure the reliability of the filtration all filter bank seals are inspected during monthly PMs.

Complaints are logged into our work order system, AIM, for proper tracking and resolution. Actions would include meeting with the complainant, identifying possible causes and steps that may include verification of air flows, a recheck on control sensors, and physical checks on all equipment. Adjustments or actions are made as needed at that time and verified for mitigation of the issue.

To calculate the gross area of building space for this credit, we only used buildings on campus that are serviced by the central plant. This excludes all UEI buildings (The Union, The WELL, etc). Additionally, to calculate the floor area of building space covered by an IAQ management program, we used only occupied building space excluding UEI buildings, closets, hallways, etc.
