Note: This pilot credit was closed for new registrations as of August 15, 2011.
This pilot credit is based upon the LEED 2009 Daylight and Views—Views credit; with a refined focus on the quality of the view occupants can access. It places a focus on specific outdoor elements and movement as criteria for appropriate views.

Provide for occupant comfort by establishing project criteria for background noise levels in each room, speech privacy and airborne sound isolation between spaces, and deter-mine the need for sound absorbing materials to limit the reverberationReverberation is an acoustical phenomenon that occurs when sound persists in an enclosed space because of its repeated reflection or scattering on the enclosing surfaces or objects within the space. (ANSI S12.602002) time and reverber-ant noise buildup in a room, and the need for any sound masking or speech reinforce-ment systems.
Achieve a direct line of sight to the outdoors via vision glazing for 80% of all regularly occupied spacesRegularly occupied spaces are areas where one or more individuals normally spend time (more than one hour per person per day on average) seated or standing as they work, study, or perform other focused activities inside a building..
Regularly occupied areas that can be counted toward this credit must meet the following criteria:
In plan view, the area is within sight lines drawn from perimeter vision glazing to provide at least an 11 degree horizontal angle of view to the perimeter vision glazing.
In section view, the area is within sight lines drawn from perimeter vision glazing to provide at least an 11 degree vertical angle of view to the perimeter vision glazing.
The view from each area must include objects at least 50 feet outside the vision glazing, objects lit with daylight that are exposed to direct sunlight or display wind movement, and natural elements (e.g. sky, vegetation, water, people, animals, or other random movement).
For private offices, the entire square footage of the office may be counted if 80% of the area satisfies the line-of-sight criteria. For other multi-occupant spacesConference rooms, classrooms and other indoor spaces used as a place of congregation for presentations, trainings, etc. Individuals using these spaces share the lighting and temperature controls and they should have, at a minimum, a separate zone with accessible thermostat and an air-flow control. Group multi-occupant spaces do not include open office plans that contain individual workstations., only the actual square footage that satisfies the line-of-sight criteria may be counted.
Lines of sight may be drawn through interior glazing. Any permanent interior obstructions (e.g. lab hoods, fixed partitions) must be considered as limiting the view angle. Movable opaque full-height or partial-height partitions must be included in calculations and line-of-sight drawings.
Fixed window treatments (e.g. ceramic frit patterns, wire meshes, bars, grill-work) in the field of view may compromise the quality of the view. The project team must submit photographs of the views from the interior spaces to demonstrate that such fixed treatments do not compromise the quality of view.
The homepage for the LEED Pilot Credit Library. The LEED Pilot Credit Library is intended to facilitate the introduction of new prerequisites and credits to LEED. This process will allow USGBC to test and refine credits through LEED 2009 project evaluations before they are sent through the balloting process for introduction into LEED.
Background for the LEED Pilot Credit Library is provided in this foundational document.
This credit will be closing in July 2011, with the launch of the LEED 2012 2nd Public Comment period. The credit has received sufficient feedback during this pilot testing period.
What this means for you:
• If you have already registered for this credit, please save a copy of the current version for your records, you do not need to take any other action and may continue to use the credit on your current project.
• If you would like to use the credit on your project(s) but have not yet registered, please do so before July to ensure that the project is eligible to earn credit.
Here's the list of credits that will be closing or modified in July: http://www.usgbc.org/ShowFile.aspx?DocumentID=9455
Does this have an affect on registering for the Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. point in Credit IEQ 8.2 Daylighting and Views - views in LEED v3?

Does anybody know a software that can help us with "3D Model showing shadows at noon on winter solstice, to show views receiving direct sunlight" requriement? Has to be simple for use by novices and hopefully, a free program downloadable from the Internet.
Ecotect (autodesk) is your best bet. Very easy to use if you have some experience in 3D modeling.
If I remember well there is a 30day free trial.
You could also use free Google Sketchup.
Just to double check, is google sketchup accepted as a good shadow render?
Would a high-rise tower be compliant with credits requirements? From the upper floors one would only see the sky outside vision glazing. Would this be enough?
According to Nancy Clanton, Clanton + Associates (and one of the primary authors of the credit):
Yes, the sky is a wonderful view with clouds and birds. Also, long distance viewing is a benefit such as looking at city skyline.
View criteria may include unexpected movement (birds and clouds), distance (greater than 50'), natural scenes (clouds) and changing light (shadows, clouds).
I am unable to access the 'Feedback Survey' web page. I'm located in China and acess to sites is often blocked. Can someone out there check if this is a local (china) issue?
If it is, via what other means (aside from using a VPN) can I acess this form?
We'll have a link up on the survey page soon for projects in China to use. Sorry for the inconvenience.
This link is now up on the participant survey page or by clicking here: http://www.usgbc.org/ShowFile.aspx?DocumentID=8815. For projects in China, you may email the completed form to email@example.com.
