Indoor Environmental Quality

Minimum Indoor Air Quality Performance

Ensure the final design of the building has suitable air quality for resident wellbeing.

● Meet at a minimum, ASHRAE 62.1 2010 performance requirements for the indoor air

quality performance.
● Have the project’s mechanical engineer conduct the calculations and provide

confirmation of compliance.

Building Flushout

● Perform an entire Building Flushout: at the end of construction before occupancy.

○ (Reduces the level of toxic chemicals building occupants are exposed by flushing them out
of the space. These chemicals or material “off-gassing” are often left in the building and are

caused by the off-gassing of non-sustainable materials used in the building during
construction.)

● Have your mechanical engineer determine how many days the flush-out needs to
occur to meet the following conditions: 14,000 cubic feet of outdoor air per square foot

of the floor area.

● Turn on all HVAC systems at full operation for the number of days determined needed

for the flush-out and have windows open.
● Maintain and indoor temperature of 60 degrees Fahrenheit or GREATER during the

flushout

● Maintain an indoor humidity level of 60% or LOWER during the flushout period
● Use a MERV 8 filter or greater during the flush out Building Flushout

● Replace the HVAC filter with at least a MERV 8 or greater (MERV 13 ideal) after the

flush out period

● Provide routine checks on all HVAC systems
● Replace the MERV 8 or higher air filters regularly
