OFFICE BUILDING

  • A 34-floor office building 43 000 м2
  • Peak energy load 1,6 MW
  • Annual energy consumption 10 mn kWh
  • Critical server equipment requires main and reserve cooling systems are operated during all year
  • Annual carbon emissions – 33 000 tons
  • Total cost of the system Euro 450 000
  • Installation and configuring the system – 30 days
  • Payback <1 year

EXAMPLE OF A TYPICAL CASE

  • Solar PV
  • 4 000 sensors that monitor energy consumption of all significant power load, thermal comfort air quality, equipment parameters
  • Integrated control of the BMS system
  • Control of all significant power consuming devices – chillers, pumps dry coolers, fan coils, heat curtains, ventilation, lighting, refrigerators, kitchen and office equipment
  • External data sources that provide data on energy prices and weather forecast
  • A digital twin

Microgrid

  • IoT Equipment control, sensors
  • Power loads, DR, emissions
  • Big Data
  • Analysis/visualization

Microgrid generation and energy flow control

Smart Energy Storage

Mesh optimization: Digital Twin + Machine Learning

SMART MICROGRID

The Energy droid:
  • Flexible flows among independent sources: Renewables integration & lower connection costs
  • Smart allocation of storage & DR among applications
  • Aggregation of small-scale distributed resources

The Energy Router:
  • IoT-based, end device microgrid model predictive control, energy mgt & DR based on digital twin
  • Agnostic smart thing mesh connection
  • Two-level optimization: AI-enabled real-time control + insights for structural efficiency investments

  • Electricity consumption down 35%
  • Heat consumption down 45%
  • Carbon emissions down 38%
  • Additional reserve margin that allows to install fast EV charging without very costly grid connection charge
  • Increased reliability and power quality for critical application
  • Generating an additional stream of revenues in the demand response market

SYSTEM INSTALLATION RESULT AND SOLVED PROBLEMS

Base period actual and reference electricity consumption based on digital twin.
After the microgrid is installed, actual consumption starts to converge to the reference load.

The microgrid also will be supplemented with ice storage that will
  • Allow to stop standby chiller operation that is currently required to maintain a reserve source of cooling for servers
  • Improve chiller efficiency
  • Earn more revenues in the demand response market
  • Further decrease peak load to connect more EV charging

HOW DOES IOE HELP SAVE ENERGY?

  • A sophisticated control model predictive (digital twin based) algorithm that prevented conflicting heating and cooling
  • Optimized the total energy consumption of all elements of the system – Dry coolers, pumps, chillers, fan coils
  • AI based algorithms that determine the actual need in resources (are people present in the area? How long would they stay? Which resources do they need?)
