I suggest here conversation about best practice for LEED Views Credit with current both schemes that are active. I even suggest we use our “template gbXML” together with GH/Dynamo scripts linked in Hydra-share to show best practices and documentation. I guess we just always need to refer to LEED version, GH or Dynamo approach or direct cloud simulation. I place all documentation for this credit below.

IEQc: 8.2 Daylight and Views – Views
Achieve a direct line of sight to the outdoor environment via vision glazing between 30 inches and 90 inches (between 0.8 meters and 2.3 meters) above the finish floor for building occupants in 90% of all regularly occupied areas. Determine the area with direct line of sight by totaling the regularly occupied floor area that meets the following criteria:
In plan view, the area is within sight lines drawn from perimeter vision glazing.
In section view, a direct sight line can be drawn from the area to perimeter vision glazing.
The line of sight may be drawn through interior glazing. For private offices, the entirefloor area of the office may be counted if 75% or more of the area has a direct line of sight to perimeter vision glazing. For multioccupant spaces, the actual floor area with a direct line of sight to perimeter vision glazing is counted.
The core and shell design must incorporate a feasible tenant layout(s) per the default occupancy counts (or some other justifiable occupancy count) that can be used in the analysis of this credit.

Achieve a direct line of sight to the outdoors via vision glazing for 75% of all regularly occupied floor area.
View glazing in the contributing area must provide a clear image of the exterior, not obstructed by frits,
fibers, patterned glazing, or added tints that distort color balance.
Additionally, 75% of all regularly occupied floor area must have at least two of the following four kinds of
multiple lines of sight to vision glazing in different directions at least 90 degrees apart;
views that include at least two of the following: (1) flora, fauna, or sky; (2) movement; and (3)
objects at least 25 feet (7.5 meters) from the exterior of the glazing;
unobstructed views located within the distance of three times the head height of the vision
views with a view factor of 3 or greater, as defined in “Windows and Offices; A Study of Office
Worker Performance and the Indoor Environment.”
Include in the calculations any permanent interior obstructions. Movable furniture and partitions may be
Views into interior atria may be used to meet up to 30% of the required area.
