How the math works

Net cost = (hardware − rebate). Annual = savings + DR revenue.

150 × $225 = $33,750 − $12,750 = $21k net. Savings $23,100 + DR $7,500 = $30,600/yr. Payback 8.2 mo.

Frequently Asked Questions

Smart thermostat savings?

Ecobee, Nest, Honeywell smart thermostats adjust schedules and learn occupancy. Typical savings: 10-15% heating cost, 10-20% cooling cost. On $800-1,500 annual HVAC spend per unit: $100-300 annual savings per unit. Owner captures if pays utilities; tenant captures if tenant pays. Even when tenant pays: rent can be raised modestly to reflect shared benefit.

Demand response programs?

Utility pays landlord/tenant to curtail HVAC during peak demand events (4-20 hours/year). Payment: $25-75 per thermostat/year. Tenant experiences 2-4°F temperature change during events. Programs: Nest Rush Hour Rewards, OhmConnect, Leap, Voltus. On 100-unit building: $2,500-7,500/year income. Aggregates across portfolio: serious add'l revenue.

Utility rebates?

Utility rebate per thermostat: $40-120 typical. Some programs cover 100% of hardware cost. Programs: DTE Energy, ConEd, PG&E, DUQUESNE LIGHT, NYSEG. Tax credit (IRA 179D): energy-efficient equipment qualifies. Stacked with demand response: effectively free thermostats with annual income stream. Best economics in utility territories with strong DR programs (CA, NY, NE, TX).

Rollout logistics?

Self-install by tenants (mailed kit): 60-80% adoption, cheapest. Professional install (HVAC tech rounds): 95%+ adoption, $75-150/unit additional cost. App onboarding: 70-80% completion of setup. Most operators: distribute at move-in for new leases, offer opt-in for existing. Smart thermostats compatible with most HVAC systems but check compatibility (no common wire = issue for 15% of units).
