Residential Building Energy Management — Multi-Floor Monitoring | EC.DATA

Residential Building Energy Management — Unit-Level Billing & Utility Allocation

EC.DATA enables multifamily residential buildings to sub-meter electricity, water, and gas at the unit level — generating accurate monthly utility invoices, eliminating disputes, and detecting leaks before they escalate.

Residential Building Energy Challenges

• Unit utility allocation based on floor area rather than actual consumption
• Manual bill-back processes prone to error and resident disputes
• Water and gas leaks undetected for weeks — invisible until the utility bill arrives
• Common-area HVAC and lighting energy unallocated and unmonitored
• No visibility into which units or systems drive peak demand charges

EC.DATA Residential Solutions

• EC.Billing: automated unit-level sub-metering with resident invoice generation
• Electric, water, and gas sub-meters at each unit via EC.Node (Modbus and pulse-output)
• EC.Alerts: leak detection alerts and abnormal consumption notifications per unit
• Common-area HVAC and pool energy sub-metering for accurate CAM allocation
• EC.Bills: master utility bill audit to catch billing errors on the service entrance account
• Resident-facing energy dashboard via the EC.DATA client portal

Residential buildings: fair billing changes resident behaviour

When residents pay a flat pro-rata share of the building's utility bill, high consumers have no incentive to conserve. EC.DATA's residential solution meters each unit individually and issues monthly statements itemizing electricity, water, and gas. Buildings that switch from pro-rata to metered billing typically see 15–25% reduction in per-unit consumption within three months — driven entirely by resident behaviour change, with no capital investment in insulation or equipment. The leakage detection capability adds another layer of value: a toilet running continuously for 30 days often goes unnoticed until EC.Alerts fires on the abnormal flow pattern.
