Action Steps

Enter the names of the regularly occupied spaces in the LEED credit form along with the total floor area for each regularly occupied space.

Fill out the LEED credit form and upload all supporting documents to LEED Online.

Determine which spaces in a project are “regularly occupied” (per LEED definition) and need to be included in the views calculations.

For naturally ventilated spaces, confirm compliance with the requirements of ASHRAE 62.1-2007 section 5.1.

For mechanically ventilated spaces, run ventilation calculations to verify that the final design meets the minimum outside air rates equal to or exceeding the ASHRAE 62.1-2007 minimum.

Continue to run calculations and develop flow diagrams to inform the design process and confirm compliance. If you are using a natural ventilation modeler for the project, use the model as a tool to inform design development.

Analyze building orientation and site selection for opportunities to provide access to views to the outside.

The mechanical engineer continues to run ventilation rate calculations during the mechanical design process to inform design development and confirm compliance with this prerequisite. The ventilation rate procedure is explained in section 6 of ASHRAE 62.1-2007. See the attached 62MZ calculator.

Consider using Computational Fluid Dynamics (CFD) modeling to determine proper opening sizes and ensure proper airflow. Some energy modeling programs also have CFD analysis capabilities.

Determine the applicable floor area for operable wall or roof openings according to ASHRAE 62.1-2007 section 5.1.
