Path to Net Zero
-
It all adds up to zero Increased incentives
for early design, technical assistance, installation and
post-occupancy
Technical resources and assistance from kick-off through
occupancy
Incentives for net-zero certification
-
Incentives & resources for early design Facilitated kick-off
meeting to adopt an EUI
target that aligns with the Architecture 2030 Challenge
Up to $10,000 to offset a design charrette to refine approach
and goals using:
EUI targeting tool Shoebox modeling
Construction Document review (required)
-
Technical assistance & incentives
75 percent of the cost of energy studies, up to $50,000,
including:
Early design shoebox modeling CFD analysis Daylighting studies
Energy modeling Commissioning design review
-
Installation incentives
Modeled savings: $0.40/kWh, $1.20/therm
- OR -
Market solutions very best level
Standard and/or special measure incentives
-
Performance & post-occupancy incentives $0.15/sq ft for
functional testing, up to $40,000
Up to $40,000, or 50 percent of cost of energy metering
-
Incentives for net-zero certification 50 percent of the cost
of net-zero certification from the International Living Future
Institute, ILFI (including application fee)
