Building owners who filed Decarbonization Plans in 2025 believe they are protected until 2030. But the DOB is now auditing "Good Faith" claims. They want to know: what did you do to maintain the equipment you're still using?
If you filed a Decarbonization Plan in 2025, you might think you're protected until 2030. You're partially correct. And that partial correctness is dangerous.
Decarbonization plans filed
Good Faith claims submitted
DOB audits begin
Good Faith claims reviewed
Final compliance deadline
Caps tighten 50%
The "Good Faith" extension allows you to avoid penalties for exceeding 2024-2029 emissions caps IF you submitted a plan showing how you will comply by 2030.
However:
The extension does NOT protect you from LL87 audit violations
It does NOT protect you from failing to maintain existing equipment
It does NOT protect you from tenant lawsuits about energy waste
"Owners can significantly reduce or defer penalties by documenting 'Good Faith Efforts,' including signed retrofit contracts, permits, financing commitments, and a clear implementation schedule."
The DOB is now asking: "You said you would install heat pumps by 2028. That's fine. But why did you let your existing boiler deteriorate so badly that it's emitting 30% more carbon today than it did in 2023?"
In 2026, DOB auditors are asking specific questions about your existing equipment:
"Show us what you did to maintain the boiler you're still using. Where are your service logs?"
"What's your current boiler efficiency? How does it compare to five years ago?"
"What have you invested in maintaining current equipment while you plan for 2028?"
"Have you done anything to improve the efficiency of existing systems?"
The bottom line: Negligence is not "Good Faith." If you ignored the equipment you currently own, the DOB can revoke your extension and impose retroactive penalties.
Required Elements
ASHRAE-level energy audit
Board-approved capital plan
Financing in place or committed
Permits filed with DOB
Signed contracts for retrofit work
What's Missing
Notice what is NOT on the required list:
Evidence that existing equipment was maintained
Documentation of current operating efficiency
Proof that the building isn't wasting energy TODAY
This is the gap the DOB is now auditing.
Smart building owners are adding these to their Good Faith files:
Vulcan installation date (capital invested in existing equipment)
Pre-installation efficiency measurements (delta-T, stack temp)
Post-installation efficiency improvement (12-18% verified gain)
Maintenance records showing proactive care
Location: Arch, Switzerland
Property Type: Residential home
Installation: Over 13 years ago
"Vulcan has now been in service for more than 13 years and still requires no maintenance. In addition, we no longer have any scale problems with our water pipes. That is why we recommend the purchase of this unit and would be prepared to buy it again if necessary."
Installation date: 13+ years of documented history
Maintenance record: Zero maintenance required
Performance proof: "No more scale problems with water pipes"
Owner satisfaction: "Would buy again"
Why This Matters for Your Good Faith File: When the DOB asks "What did you do to maintain your existing equipment?", a 13-year track record of documented, maintenance-free scale prevention is powerful evidence. It shows proactive ownership, not neglect.
Residential House in Arch — 13 years of maintenance-free protection
Proof of capital invested in equipment preservation, not just promises.
Documented baseline showing existing efficiency (or lack thereof).
Verifiable 12-18% efficiency gain = proof of proactive maintenance.
Like the homeowner in Arch, you can document years of maintained efficiency.
When the DOB asks "What did you do to maintain your existing equipment?", Vulcan documentation is your answer.
Sample ROI Calculation
Annual fine exposure (typical building, 200 MT excess) | $53,600 |
10-year exposure | $536,000 |
Good Faith extension (with documentation) | Penalties reduced/deferred |
Good Faith extension (without documentation) | At risk of revocation |
Vulcan model (typical installation) | |
Value of documented Good Faith | $500,000+ preserved |

Fully cast in acrylic for optimal quality endurance
Do-it-Yourself installation without cutting pipes
Zero salt, zero chemicals, zero maintenance
ASHRAE-level energy audit – Completed within last 5 years
Decarbonization plan – Board-approved, with timeline to 2030
Financing documentation – Commitments, grants, or budget allocations
Permit filings – DOB permits for planned work
Signed contracts – For heat pumps, retrofits, or other improvements
Maintenance records – Vulcan installation, efficiency measurements, service logs
Pre/post efficiency data – Delta-T improvements, stack temperature reductions
Long-term documentation – Like the 13-year homeowner in Arch
