Four cards, every building, every day.
Usage, fine, savings, anomalies. Refreshed nightly. Exportable to a PDF that holds up in audit.
Monthly usage, instantly
Every meter read rolls up to a weather-normalized timeline. See exactly where your kWh and therms went — no spreadsheets.

Fine projected in real time
LL97, BERDO, BEPS — every covered regime is computed against your YTD trajectory. Know your May 1 number in April.

IPMVP-grade savings receipts
Option C baselines, ASHRAE G14 quality gates, dollar-exact attribution. Hand these reports to a CFO with confidence.

Anomalies before bills
Z-score detection against your own baseline catches a degrading chiller two months before it shows up on a utility bill.

Built for procurement reviews.
Enterprise buyers don't ask where your code lives — they ask about SOC 2, SSO, MFA, audit logs, and incident response. We ship every one of those from day one, inheriting compliance posture from the certified infrastructure we run on.
Encryption at rest & in transit
AES-256 at rest via Timescale Cloud, TLS 1.3 in transit, HSTS preloaded. Field-level encryption for PII.
Row-level tenant isolation
Every tenant table carries a Postgres RLS policy keyed on the org ID set by the auth middleware. Belt-and-suspenders with app-level filtering.
Append-only audit log
Every insert, update, delete, and auth event lands in an append-only log. DB triggers block rewrites even from a compromised app role.
Clerk for identity
SOC 2 Type II identity provider with SSO, MFA, and audit log built in. We never store passwords.
All customer data in AWS us-east-1
Stored in Timescale Cloud with encrypted daily backups and 30-day point-in-time recovery. Data never leaves the region without your explicit export.
