Option 1, Path 1: Daylight Simulation

Glare-control is required for all spaces using Option 1: Daylight to demonstrate compliance. This requirement is generally satisfied through the use of adjustable blinds and/or exterior shading devices.

Determine the total area of compliant, regularly occupied spaces, and the overall percentage of compliant spaces according to the compliance path you selected before the performance period (as outlined below).

There are several free-download programs available that allow users to calculate floor areas from electronic floor plans (PDF or CAD files). (See Resources.)

Regularly occupied spaces are those in which workers are seated or standing as they work during the day. In residential applications, regularly occupied spaces include all spaces except bathrooms, closets, and other storage or utility areas. Non-regularly occupied spaces include corridors, bathrooms, storage, and mechanical rooms.

Identify your building’s regularly occupied spaces and calculate their total area.

Most project buildings that qualify for Daylight compliance would also meet the Views requirements. Teams most often choose to pursue this credit through Option 2: Views, because the documentation is easier and more efficient, though it can still be time-consuming, especially if building floor plans are not easily accessible. 

Option 2: Views

The Daylight path for measurement is more doable, but unlike other Daylight paths, your results can be affected by shading influences on your building, such as adjacent structures.
