What phase does the IAQ Credit Enhanced Indoor Air Quality Strategies pertain to?

The Enhanced Indoor Air Quality Strategies credit primarily pertains to the design phase because it focuses on establishing a framework to ensure that the building's indoor air quality (IAQ) meets high standards before construction begins. During the design phase, teams can incorporate various strategies and technologies aimed at improving indoor air quality, such as selecting appropriate materials, optimizing ventilation, and ensuring effective moisture control. This proactive approach allows for the integration of key considerations into the overall design strategy, leading to healthier indoor environments for occupants.

Implementing these strategies during the design phase is critical, as the decisions made in this stage have long-term effects on the building's IAQ and the health and wellbeing of its users. By setting these standards early, teams can better manage indoor conditions throughout the life of the building. Although other phases like construction, occupancy, and planning are also relevant to air quality, the specific strategies outlined in this credit are most effectively applied and documented during the design phase.
