More fresh air means healthier buildings. Building on IEQp1: Minimum Indoor Air Quality Performance, this credit calls for exceeding by 30% the minimum outside air requirements set by ASHRAE 62.1-2007. Our indoor environments are burdened by carbon dioxide produced by occupants and by off-gassing of construction materials and furnishings. These conditions can cause fatigue and contribute to occupant health problems. Increased ventilation is one way to mitigate these problems.

More fresh air means healthier buildings. Building on IEQp1: Minimum Indoor Air Quality Performance, this credit calls for exceeding by 30% the minimum outside air requirements set by ASHRAE 62.1-2007. This credit applies only to occupied spaces of the building unlike EQp1, which applies to all the rooms as per by ASHRAE 62.1. This increased ventilation helps reduce concentrations of carbon dioxide produced by occupants, and pollutants produced by off-gassing of construction materials and furnishings.
