Minimum Indoor Air Quality Performance Calculator

The Minimum Indoor Air Quality Performance Calculator can be used for projects using ASHRAE 62.1 to comply with LEED BD+C, ID+C and O+M EQ Prerequisite Minimum Indoor Air Quality Performance, EQ Credit Increased Ventilation, and EQ Credit Enhanced Indoor Air Quality Strategies, Option 2, Strategy B: Increased Ventilation, as well as LEED Homes and Multifamily Midrise EQ Prerequisite Ventilation. The calculator accommodates all ventilation types (multiple zone, single-zone, 100% outside air) in one spreadsheet. Assumptions for occupancy categories are from ASHRAE 62.1-2010 (for LEED v4 projects) and ASHRAE 62.1-2007 (for LEED 2009 projects).
