In regards to the Daylight & Views supplemental spreadsheet which is now available under the 'Credit Resources' link in LEED Online:
When selecting to pursue Option 2, Views - this spreadsheet contains the following language under tab F "Views":
"1 Measures are defined as follows:
Measure 1. Multiple lines of sight to vision glazing in different directions at least 90 degrees apart
Measure 2. Views that include at least 2 of the following: 1) vegetation, 2) human activity, or 3) objects at least 70 feet
from the exterior of the glazing
Measure 3. Access to unobstructed views within 3 times the head height of the vision glazing
Measure 4. Access to views with a view factor of 3 or greater, per the Heschong Mahone Group study, Windows and Offices;
A study of Office Worker Performance and the Indoor Environment. (Refer to page 47, http://www.h-m-g.com/_vti_bin/
shtml.dll/downloads/Daylighting/day_registration_form.htm)"
Although these requirements have never been mentioned previously in the reference guide - are these now required in order to document compliance with this credit? If yes, are all areas with views required to comply with all 4 measures, or should each view comply with at least 1 measure?
For buildings in dense urban areas, would a view of an occupied adjacent building with windows be considered 'Measure 2: A view that includes human activity, and objects at least 70 feet from the exterior of the glazing?

Jason, I haven't double-checked the spreasheet so I'm not sure about this, but those sound like the Exemplary Performance requirements for Views -- and thus most projects don't need to document them.Does that make sense?
