ASHRAE 62.1 Ventilation for Acceptable Indoor Air Quality is published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). First published in 1973 as standard 62, standard 62.1 specifies requirements for new and existing buildings commercial buildings. Residential building requirements are covered in the corresponding ASHRAE 62.2 Ventilation and Acceptable Indoor Air Quality in Residential Buildings standard.

The standard defines the minimum ventilation rates and other measures intended to provide indoor air quality that is acceptable to human occupants. While many aspects of a buildings ventilation system are described, the primary requirements as they relate to Building Energy Modeling are the minimum ventilation rates per person and area defined for a range of occupancy categories.

cove.tool refers to the Minimum Ventilation Rates in Breathing Zone tables of ASHRAE 62.1 for different type of buildings to populate the default inputs.  Users are encouraged to review these inputs with the project engineers to confirm they match your project's design intent.
