Automated Building Energy Optimization

Automated Building Energy Optimization refers to software that continuously monitors and controls building systems—primarily HVAC, but also lighting and other services—to minimize energy use and operating costs while maintaining occupant comfort. It ingests high‑frequency data from building management systems, sensors, and meters, detects inefficiencies or faults, and automatically adjusts setpoints, schedules, and control strategies in real time. This matters because commercial and residential buildings are major drivers of both operating expenses and carbon emissions, yet are often tuned manually, infrequently audited, and operated far from optimal performance. By using data‑driven models and control logic hosted in the cloud, these applications reduce energy consumption, cut utility bills, lower emissions, and decrease reliance on manual engineering work. They also surface maintenance issues earlier, improving reliability and extending equipment life.

The Problem

Closed-loop HVAC optimization that cuts energy use without breaking comfort

Organizations face these key challenges:

1

Energy spend is volatile and higher than expected despite “tuned” BMS settings

2

Hot/cold complaints spike during weather swings or schedule transitions

3

Faults (stuck dampers, leaking valves, simultaneous heating/cooling) persist for weeks

4

Operators change setpoints manually with little measurement of savings or comfort impact

Impact When Solved

Lower energy costs by 30%Fewer hot/cold complaintsEarlier fault detection and resolution

Rule-Guided Setpoint Advisor

Typical Timeline:Days

Start by ingesting BMS trends and meter data, then generate operator recommendations (e.g., schedule tightening, static pressure reset, supply air temperature reset) using configurable rules and constraint checks. The system does not directly control equipment; it produces change proposals with estimated impact and comfort guardrails. This validates data availability, operator workflow fit, and baseline savings opportunities quickly.

Key Challenges

  • Messy point naming and missing sensors leading to brittle rules
  • Separating energy waste from legitimate comfort needs (e.g., extreme weather)
  • Operator trust: recommendations must be explainable and safe
  • Baseline variability across weekdays, seasons, and tenant schedules
