Submetering
Submetering measures electricity at the unit, tenant, and equipment level. Owners get precise visibility and can buy power at a lower commercial rate through a master meter, while billing residents fairly at the standard residential rate and keeping the spread.
For large portfolios it is one of the most reliable ways to lift net operating income. Submetering typically generates around $400 per unit each year, roughly a 1% NOI increase, which can translate into double-digit asset-value appreciation at typical multifamily cap rates.
2 Charlton, a 176-unit Manhattan co-op, nets roughly $94,000 a year from submetering alone, on track for a payback under three years.
Submetering is only the beginning. Once it is in place, solar, EV charging, and battery storage layer onto the same platform, with the revenue reinvested into the next move.
Local Law 97, part of New York City's Climate Mobilization Act, sets carbon-emissions limits for most buildings over 25,000 square feet, covering roughly 50,000 properties across the city. Limits apply now and tighten sharply in 2030.
Buildings over the limit face penalties currently set at $268 per metric ton of CO2 equivalent above their cap, assessed every year. Local Law 88 adds its own metering and lighting-upgrade requirements for commercial tenants on top.
Submetering is the starting point for both. It gives owners the unit-level and equipment-level data that makes it possible to target the moves that cut emissions and cost together, and to prove compliance instead of estimating it.
Submetering means measuring electricity use at the unit, tenant, or equipment level inside a building that would otherwise run on one master meter. It lets an owner buy power in bulk at a commercial rate and bill each resident individually at the standard residential rate.
Most multifamily buildings see around $400 per unit each year, close to a 1% increase in net operating income. 2 Charlton, a 176-unit Manhattan co-op, nets roughly $94,000 a year with a payback under three years.
Yes. Submetering electricity in New York is regulated by the state Public Service Commission, and DaisyChain's platform is built around that framework, from metering through resident billing.
It gives owners the granular energy data that Local Law 97 compliance depends on: where load is going, building by building and system by system, so upgrades can be sequenced by actual impact instead of guesswork.
