EQ Credit: Enhanced Indoor Air Quality Strategies

Option 1. Enhanced IAQ Strategies
Mechanically Ventilated Space(s)
  1. Ensure that entryway systems are installed at all regularly used exterior entrances.
  2. Ensure that documentation is provided that demonstrates the spaces have been designed for sufficient exhaust and separation. The documentation must include a list of spaces, exhaust rates, and a description of the separation strategy.
  3. Ensure that all ventilation systems that supply outdoor air to occupied spaces have filtration with a minimum rating MERV 13 (Class F7), and that supporting design documentation (e.g., mechanical schedules, specifications) confirms compliance.
Option 2. Additional Enhanced IAQ Strategies
Mechanically Ventilated Space (s) - select one

A. If the Increased ventilation is pursued and Demand Controlled Ventilation is included within the system design, ensure the CO2 setpoints are consistent with the expectations of providing 30% increased ventilation air to the zone. Ensure that documentation is provided that demonstrates the spaces have been designed for sufficient exhaust and separation. The documentation must include a list of spaces, exhaust rates, and a description of the separation strategy.
B. Ensure that CO2 sensors are installed within each densely occupied zone. Confirm that occupant density is reported consistently with the EQp Minimum IAQ Performance Calculator submitted within EQp Minimum IAQ Performance.
