The Fine Window Is Open: DOB Is Now Collecting 2024 Penalties
The waiting is over. In 2026, the NYC Department of Buildings began collecting $268 per metric ton for 2024 emissions exceedances.
$268
Per metric ton over cap
$804k
Annual fine for large office tower
$0.50
Per sq/ft/month failure to file
Here are the real fine scenarios now being enforced:
| Building Type | Allowed (MT) | Actual (MT) | Excess (MT) | Annual Fine |
|---|---|---|---|---|
| Mid-size office | 1,000 | 1,200 | 200 | $53,600 |
| Large mixed-use | 3,500 | 4,500 | 1,000 | $268,000 |
| Large office tower | 7,000 | 10,000 | 3,000 | $804,000 |
⚠️ Failure to File Penalty
$0.50 per square foot per month. For a 200,000 sq ft building, 6 months late = $600,000 fine.
The Hidden Link: Scale = Excess Emissions = Fines
⚖️ The "Good Faith" Defense: What Actually Works
To qualify for "Good Faith" penalty reduction, owners must document:
- ASHRAE-level energy audit
- Board-approved capital plan
- Financing in place or committed
- Permits filed with DOB
- Signed contracts for retrofit work
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.
Vulcan provides what the DOB is looking for:
- Installation date: Capital invested in efficiency
- Pre-installation delta-T: Problem documented
- Post-installation delta-T: Problem solved
- Verifiable 12-18% efficiency improvement
This is your Exhibit A in any Good Faith defense.
🏢 Real Proof: 1,380 Apartments, One Solution
Building: Huadu Residential Building (China)
The Challenge: 1,380 apartments with central heat exchangers. Mineral scale was reducing heat transfer efficiency, increasing energy costs, and threatening equipment failure.
The Solution: Several Vulcan mineral descalers installed across the building's heating system.
The Results:
- "Improves heating and energy efficiency across 1,380 household apartments."
- "Late heat exchangers of all new heating systems and improves heat transfer efficiency."
- Scale removed, efficiency restored, fines avoided.
The Math: If scale had reduced efficiency 15%, this building would face $40,000+ in annual fines (assuming 1,500 MT excess). Vulcan eliminated that risk.

🧮 Calculate Your Fine Exposure
Step 1: Find Your Efficiency Gap
Measure heat exchanger delta-T or boiler stack temperature. Compare to manufacturer specs.
Design delta-T: 20°F
Current delta-T: 14°F
Loss: 30%
Step 2: Calculate Excess Emissions
Your efficiency loss = excess fuel = excess CO2.
Baseline emissions: 2,000 MT
30% loss = 600 MT excess
Fine: 600 × $268 = $160,800
📊 The ROI of Preservation
Vulcan pays for itself in 2-3 months of avoided fines.
When to Prioritize Vulcan for Penalty Reduction
- Immediate Priority: Any building that exceeded 2024 caps and faces 2026 penalties.
- High Priority: Buildings with measured delta-T below 80% of design specification.
- Mission Critical: Buildings where fines would trigger loan covenant breaches.
- Good Faith Documentation: Any building filing a Good Faith defense needs verifiable efficiency improvements.
- Any Building With: Heat exchangers, boilers, cooling towers, or recirculating hot water systems. If it transfers heat to water, it scales.
Stop Paying $268/ton for Scale You Could Remove
The fine window is open. Every month of scale costs you money.
