Pricing questions
Conditioned area only — the floor area your HVAC system actively heats and cools. Parking structures, unconditioned storage, and mechanical rooms are excluded. If you're not sure of your conditioned area, we can estimate it from your BMS zone list during the observation phase.
No issue. The Portfolio plan covers any mix of office, retail, and healthcare administrative buildings. Each building gets its own thermal model. Pricing is based on total conditioned square footage across all buildings, not by building type.
The Portfolio plan already prices 5 buildings at $490/month — significantly lower per building than the Single plan. For 10+ buildings, Enterprise pricing is negotiated based on total portfolio size. Contact us for a quote.
At Day 30, we send your savings report and ask if you'd like to continue. If yes, billing starts at month 2 on the plan you select. If no, the BMS connection is closed and no charge occurs. No automatic renewal, no credit card required to start the pilot.
The savings methodology is described in detail in every monthly report: comparison baseline is the trailing 90-day average energy cost for the same calendar period, weather-normalized using degree-day adjustment. We compare to what you were actually spending, not a theoretical optimal. The methodology PDF is included in every report.
Email [email protected] with your cancellation request. We'll close the BMS connection within 24 hours and confirm in writing. No cancellation fees, no notice period required on monthly billing. Annual billing refunds the unused portion pro-rated.

5:1 ROI in year one — at 30% savings.
This uses 30% savings, the low end of the 25–40% range we see across pilot buildings. For a Pacific Northwest office on PGE Schedule D with standard demand charges, this is conservative. Your actual number depends on your building's thermal inertia profile, current tariff structure, and how much your BMS schedule is currently missing. The 30-day pilot produces your actual baseline and savings data before any billing starts.
