At the end of construction, the architect revisits the preliminary calculations to confirm that the percentage of reused building elements is above the 50% threshold required for the credit.
Total the square footage with access to views and enter it in the LEED credit form.
Include more than one sight line if necessary to meet the requirement for all spaces.
Create a floor plan showing areas with access to views as distinct from areas with no access to views.
Direct-line-of-sight can pass through two interior glazing surfaces before reaching exterior glazing, but not through solid doors, walls, or partitions taller than 42”.
Direct-line-of-sight is determined by visibility between the vision glazing (between 2’6” and 7’6” inches above the floor) without obstructions such as full-height partitions or solid doorways.
Calculate the floor area with direct-line-of-sight to perimeter vision glazing for each regularly occupied space. Moveable partitions must be included in your calculations.
Plan View Direct Line of Sight to Perimeter Glazing Calculations:
In projects with operable windows, occupants may not know when conditions are best for opening the windows. Implement a system so that occupants are informed of when to open and close the windows to achieve designed performance and optimal comfort.
Ensure that glare controls are factored into the design of daylighting and views.
