End of Life Tips

For alignment with LEED Standards

  • Regional Materials: For credit achievement calculation, products sourced (extracted, manufactured, purchased) within 100 miles (160 km) of the project site are valued at 200% of their base contributing cost.
    • BD+C and ID+C MR: Building Product Disclosure and Optimization – Sourcing of Raw Materials and Material Ingredients
    • O+M MR: Purchasing - Facility Maintenance and Renovation
  • Energy: Comply with ANSI/ASHRAE/IES Standard 90.1-2010.
    • BD+C EA: Minimum Energy Performance
  • 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
