Automated Utility Intelligence
for Real Estate Portfolios.
Ara acquires utility bills portfolio-wide, validates consumption data, and produces GRESB-ready datasets at scale — eliminating the manual collection that most teams fail to complete before submission.
Automated Utility Intelligence
From data gap to
GRESB-ready coverage.
Most portfolios enter GRESB submission season with incomplete water data. Ara closes that gap before it costs you points.
The Problem
Most portfolios enter GRESB submission
with a data coverage problem.
The WT1 indicator is worth up to 4 of ~7.67 available water points — more than any other water indicator. It measures data coverage, not performance. A portfolio that has improved water efficiency but has incomplete data scores lower than a portfolio that has done less but documents everything. Ara exists to close that gap.
Problem 01
Manual bill collection takes 30+ hours per GRESB cycle
Sustainability teams spend weeks chasing utility providers, property managers, and sub-meter data before each submission. Every missed property is a coverage gap that costs points — not because the water wasn't managed, but because the data wasn't collected.
Problem 02
Missing coverage suppresses your WT1 score
WT1 awards points based on the percentage of portfolio floor area for which you can submit verified consumption data. A 10-property portfolio where 3 properties have gaps loses WT1 points regardless of how well the other 7 are managed. Coverage, not performance, drives this indicator.
Problem 03
Billing errors go undetected for months
Without automated validation, billing errors — rate misclassifications, estimation overrides, meter substitution errors — compound over multiple billing cycles. The average commercial property with unreviewed bills carries 8–12% in recoverable overcharges. Ara flags these before they reach year-end.
On the DiamondRock portfolio, Ara enabled GRESB-reported documentation across 31 assets — converting verified field savings into submission-ready data that satisfied WT1 requirements and contributed to a 4-star overall GRESB rating.
GRESB Water Indicators
Ara directly addresses
three GRESB water indicators.
Not as a secondary benefit — as its primary purpose. Every dataset Ara produces is structured to satisfy the specific evidence requirements of WT1, MR3, and RA4.
"Ara enabled us to close the coverage gap that had been suppressing our water score for two consecutive cycles. The data was submission-ready within weeks."
