Provide optimal shading

Rationale: Providing shading on all windows enhances occupant control over temperature, glare, and nighttime darkness, which can lead to reduced task-related eye strain, contributing to improved thermal comfort and enhanced sleep quality.

Requirements

Demonstrate compliance with one of the options below:

Option 1 - Shading on All Windows (Full Credit):

Provide shading devices to manage daylight exposure that meet all of the following requirements:

1. Provide shading on all windows within all regularly occupied spaces within the building.
