End of Life Tips

• Usually reused by future occupants.

For alignment with LEED Standards

• Daylight Penetration: Demonstrate through computer simulations that 75% or more of all regularly occupied areas (for LEED BD+C and ID+C; 50% for O+M) achieve daylight illuminance levels of a minimum of 300 lux and a maximum of 3,000 lux in a clear sky condition on September 21 at 9 a.m. and 3 p.m. OR use a combination of side-lighting and/or top-lighting to achieve a total daylighting zone for the same percent of all the regularly occupied spaces.
  • BD+C and ID+C EQ: Daylight
  • O+M EQ: Daylight and Quality Views
