Energy data for commercial real estate portfolios
Compliance deadlines, investor scorecards and rising energy cost all land on the same desk, and they all need the same thing: accurate, whole-building energy data across the portfolio.
The problem
A national portfolio can face several different building performance standards at once. More than 40 US cities and states now require benchmarking or set emissions limits, with penalties reaching $10 per square foot in some jurisdictions and $268 per tonne of CO2 over the cap under NYC Local Law 97.
Investors add their own pressure. The 2026 GRESB real-estate standard rewards portfolios that report actual metered data across their assets and scores estimates lower, so data quality is now worth points.
And the recurring cost is the data work itself: assembling bills, normalizing formats and entering consumption for benchmarking can exceed $40,000 a year for just 20 buildings.
Where we help
Portfolio benchmarking, always current
Turn every bill into clean, whole-building data feeding EUI and ENERGY STAR, so a benchmark is a query, not an annual project.
Multi-jurisdiction compliance
Track each building's obligation and its gap to the emissions limit through the year, across every city you report in.
GRESB and ESG reporting
Produce actual, auditable metered data across assets, with the source bills linked, so the number holds up under review.
Find billing errors at the portfolio level
Validate every bill against the tariff and surface the demand-charge and rate-class errors that quietly inflate operating cost.
What you get
- Whole-building energy data across the portfolio, in one model
- Benchmarking and emissions reporting ready on demand
- Operating cost recovered from billing errors
- A defensible, auditable record behind every number
