Commercial Building Energy Management — BMS-Grade HVAC & Sub-Metering | EC.DATA
Commercial Building Energy Management — Occupancy-Driven HVAC & Tenant Sub-Metering
EC.DATA delivers BMS-grade HVAC control, tenant energy billing, power quality monitoring, and LEED/EDGE compliance reporting for commercial office buildings — without replacing existing BACnet or Modbus controls infrastructure.
Commercial Building Energy Challenges
- Low and variable occupancy with full-power HVAC serving empty floors
- Service entrance power quality events affecting sensitive IT equipment
- Stranded chiller capacity running inefficiently during partial-occupancy periods
- Tenant energy allocation based on floor area rather than actual consumption
- After-hours HVAC waste from tenants requesting out-of-hours conditioning without metered cost
- CRREM carbon intensity reporting required by institutional owners
EC.DATA Commercial Building Solutions
- EC.BMS: HVAC zoning by occupancy — ramp down empty floors automatically
- EC.PQ: service entrance power quality monitoring for IEEE 519 compliance
- EC.Chillers: chilled-water plant COP optimization for partial-load conditions
- EC.Billing: tenant sub-metering with accurate monthly invoicing
- EC.GAIA: predictive occupancy modelling and proactive HVAC scheduling
- After-hours HVAC metered billing and schedule control (EC.Alerts)
- LEED/EDGE and CRREM energy intensity and carbon reporting (EC.EMS)
Commercial buildings: half-empty but fully heated
Modern office buildings average 40–60% occupancy, yet HVAC typically serves every floor at design capacity. EC.DATA integrates with existing BACnet and Modbus HVAC controllers via EC.BMS — no rip-and-replace — and adds occupancy sensor data from LoRaWAN desk and people-counting sensors to drive zone-level setpoint adjustments. Buildings consistently achieve 20–35% HVAC energy reduction without any mechanical changes, purely from occupancy-responsive scheduling.
