Naturally ventilated buildings can attempt this credit, but the requirements are more challenging. You’ll need to produce design diagrams or analytic models illustrating compliance with the relevant standards. This compliance path is rarely pursued for existing building certifications, due in part to the simple lack of many naturally ventilated buildings pursuing LEED-EBOM certification.

Conduct a second set of airflow measurements and compare these to your original VRP calculations to verify that the outdoor air rate for each ventilation system is at least 30% better than ASHRAE 62.1-2007.

You can increase ventilation rates by adjusting all dampers and louvers in the ventilation system throughout the building. In addition, visually inspect all intake vents and registers and remove any obstructions that restrict outdoor airflow. These activities should also become a part of regular preventive maintenance and ongoing commissioning tasks.

Increasing the amount of fresh air in your building may also have positive impacts on health and productivity of employees. There have been a number of studies that linked indoor environmental quality with occupant health and productivity—see Resources.
