How does CIRRUS Low Carbon compare to LEED®?
LEED is the most well established certification found around the world. Its early and progressive start set the stage for other certifications that followed.
CIRRUS Low Carbon focuses on REDUCING CARBON. We believe that when we focus on the root cause of climate change, we make the greatest impact and our customers come out ahead.
Key wins from CIRRUS Low Carbon:
- Significant rate reduction from PACE Equity plus reduced construction period interest
- No cost to participate (skip the high price tag associated with other green building programs)
- Third party verification when the building design is finalized (rather than when construction and commissioning is complete) which means you have the marketing kit before you reach Certificate of Occupancy.
