Portfolio Building Energy Management Hub

The Problem

“Your buildings burn energy and fail unexpectedly because controls are manual and reactive”

Organizations face these key challenges:

Energy bills fluctuate with no clear root cause; setpoints and schedules drift over time

Comfort complaints trigger firefighting, while the BMS generates noisy alarms that get ignored

Maintenance is reactive or calendar-based, leading to preventable failures and expensive after-hours repairs

Operational data is fragmented across BMS, meters, CMMS, and vendor portals, slowing diagnosis and optimization

Impact When Solved

Lower energy spendFewer unplanned outagesOptimize portfolios without adding headcount

The Shift

Before AI~85% Manual

Human Does

•Manually tune HVAC/lighting schedules and setpoints based on experience
•Investigate comfort complaints and alarms by pulling trends and walking the site
•Plan maintenance on fixed intervals and respond to breakdowns with emergency work orders
•Run periodic retro-commissioning/energy audits and implement recommendations months later

Automation

•Basic rule-based BMS control and threshold alarms
•Simple reporting/dashboards from meters and BMS trends
•Work order tracking in CMMS (no predictive prioritization)

With AI~75% Automated

Human Does

•Approve/override automated control strategies and define guardrails (comfort, IAQ, safety, tenant SLAs)
•Execute prioritized maintenance actions and verify fixes
•Manage exceptions, escalations, and capital planning based on AI insights

AI Handles

•Continuously optimize control: setpoint resets, scheduling, sequencing, and demand-limiting within constraints
•Detect faults and degradation early (e.g., stuck dampers/valves, simultaneous heat/cool, sensor drift)
•Predict maintenance needs and recommend the next best action with estimated savings/impact
•Correlate weather, occupancy, tariffs, and equipment performance to forecast load and prevent peaks

Operating Intelligence

How Portfolio Building Energy Management Hub runs once it is live

AI runs the operating engine in real time.

Humans govern policy and overrides.
