NOTE: Meeting the baseline or industry average in Table 2 can achieve no more than two points.
Option 1. Whole-building Life Cycle Assessment (1–6 points New Construction, 1–7 points Core and Shell)
Conduct a cradle-to-grave (modules A–C, excluding operating energy and operating waterrelated energy) whole-building life-cycle assessment (WBLCA) of the project’s structure, enclosure, and hardscape materials. Compare results to a baseline developed for the project and earn points according to Table 1.
Include results for the following impact categories in the WBLCA report:
-
Global warming potential (GWP) (greenhouse gases), in kg CO2e
-
Depletion of the stratospheric ozone layer, in kg CFC-11e
-
Acidification of land and water sources, in moles H [+] or kg SO2e
-
Eutrophication, in kg nitrogen eq or kg phosphate eq
-
Formation of tropospheric ozone, in kg NOx, kg O3 eq, or kg ethene
