to provide access to views of the outdoors to increase occupant
productivity and comfort. Although glazing will increase costs,
maintenance, and decrease envelope insulation over standard walls,
energy savings in lighting power density has been shown by up to
30% in some office buildings.
Provide a direct line of sight to the outdoors for building
occupants in 90% of all regularly occupied areas.
- Consider vision glazing (glass between 2'6" and 7'6") only when
applying lines of sight to interior spaces.
- Consider footprint shape and space layout early in design to
maximize views to glazing.
- Open office floor plans with centralized building core designs
more readily achieve this point.
- Design the building floorplate so that as many regularly
occupied spaces as possible are located near the perimeter, with
access to glazing. Open offices should be located at the perimeter
with enclosed spaces and support areas near the building core.
- Glazing should be shaded appropriately to control solar heat
- Include interior transom glazing to add views to enclosed
spaces away from the perimeter of the building.
- Perform preliminary space area calculations early in design to
determine if design approach will easily achieve the appropriate
level of views for the building occupants.
- 64% of all California LEED Certified projects achieved this
credit for LEED v2.1.
