Energy and utility data for multifamily portfolios

Apartment portfolios waste a large share of the energy they buy, and owners often cannot see it because the data is split between the building and the units.

The problem

Studies suggest the average apartment community wastes about 33 percent of the energy it consumes, and a strategic approach can improve US multifamily efficiency by 15 to 30 percent (ACEEE).

The blind spot is structural. More than 60 percent of multifamily households pay their own energy costs, and utilities often will not release individual unit data to the owner without each tenant's authorization, so owners cannot see in-unit performance.

Submetering helps, and it pays: it can cut consumption by up to 40 percent and lift net operating income and valuation. But it also multiplies the number of bills and data streams someone has to reconcile.

Where we help

01

Whole-building and submetered data in one place

Bring house meters, submeters and unit bills into a single validated model so you can see performance at every level.

02

Benchmark and comply

Meet multifamily benchmarking requirements with clean data instead of estimates, across every property.

03

Protect NOI

Catch billing errors and reconcile submetered recovery so utility cost does not quietly eat into margin.

04

ESG and refinance readiness

Produce the energy and emissions data lenders and ESG frameworks increasingly ask for at refinance or sale.

What you get

  • A single view across house meters, submeters and unit bills
  • Utility cost recovered and NOI protected
  • Benchmarking and ESG data ready without estimates
  • Less manual reconciliation for the property team

Frequently asked questions

How do owners get unit-level data given the authorization wall?

Utilities often require each tenant's authorization to release individual unit data. We support compliant collection flows and normalize whatever arrives, from submeter feeds to tenant-provided bills, into one model.

Does submetering actually improve returns?

Yes. Industry data shows submetering can cut consumption by up to 40 percent and, by reducing owner-paid utility cost, improve net operating income and building valuation.
