If your building heats with Con Edison district steam, you don't need a reminder of how punishing monthly utility bills have become.

When Local Law 87 (LL87) compliance comes around, many district steam building owners view it as just another bill from the city.

That’s a mistake. In a steam-heated building, your mandatory LL87 audit is actually your best tool to uncover hidden mechanical waste, slash utility bills, and shield your asset from escalating Local Law 97 (LL97) carbon penalties.

The ConEd Steam Reality: High Rates + System Inefficiency

We can’t control Con Edison’s steam rates. What we can control is how much steam your building needlessly consumes—and wastes—every single day.

District steam systems are inherently complex. Over time, valves stick, sensors drift, vacuum pumps fail, and steam traps blow out. Unlike standard gas or oil boilers where inefficiencies slowly bleed money, a malfunctioning steam system burns through cash at an alarming rate due to high fuel costs.

Worse yet, steam carries a heavy carbon coefficient under Local Law 97 rules. Every pound of wasted steam isn't just an inflated ConEd bill today—it's a potential carbon fine tomorrow.

Turning Mandatory LL87 Work into Steam Cost Relief

Local Law 87 mandates an Energy Audit and Retro-commissioning (RCx) process every 10 years for qualifying NYC properties. While many view this as administrative friction, a steam-focused LL87 audit provides immediate operational value:

Pinpointing Hidden Steam Losses: Identifying failed steam traps that allow live steam to blow straight into condensate return lines without heating the building.

1. Optimizing Control Strategies: Fixing miscalibrated outdoor air reset controls and steam station pressure regulators that over-supply steam during mild weather.
2. Insulation & Heat Recovery: Spotting bare steam piping and uninsulated valves in mechanical rooms that radiate expensive heat into unconditioned spaces.

What We Look For in District Steam Buildings

When auditing a steam-heated building, our priority is finding practical, high-ROI fixes that immediately trim your ConEd statement:

1. Steam Trap Testing & Auditing: Identifying leaking traps that drain thousands of dollars per month in live steam.
2. PRV & Control Valve Performance: Checking pressure reducing valves (PRVs) to ensure the system operates at the lowest safe pressure.
3. Condensate Return Health: Evaluating condensate tanks, pumps, and heat exchangers to recover maximum heat energy before water leaves the system.
4. Zone & Radiator Valve Regulation: Resolving localized overheating issues that force residents to open windows in the dead of winter.

Stop Paying for Steam You Don't Use

You don't have to accept staggering ConEd steam bills as an unchangeable cost of doing business in NYC. By using the required Local Law 87 process strategically, you can identify mechanical failures, reduce steam consumption, and build a buffer against 2030 Local Law 97 emissions caps.
