Office buildings, retail facilities, warehouses, healthcare properties, educational facilities, hotels, and industrial sites can use energy-management practices to understand consumption patterns and coordinate building systems.

A commercial energy-management strategy may combine energy meters, building automation, monitoring platforms, HVAC controls, lighting controls, equipment scheduling, benchmarking, and ongoing performance analysis.

The objective is to create better visibility into building energy performance while supporting reliable facility operations.

What Is Commercial Energy Management?

Commercial energy management is the structured process of monitoring and managing energy use across a facility.

A program may involve:

• Electricity and fuel monitoring

• HVAC management

• Lighting controls

• Building automation

• Equipment scheduling

• Energy benchmarking

• Demand monitoring

• Building-performance analysis

• Preventive maintenance planning

• Efficiency project evaluation

Energy management can be centralized through a building management platform or distributed across individual systems and meters.

Building Energy Monitoring Systems

Energy monitoring provides facility teams with information about when, where, and how energy is being consumed.

Common monitoring components include:

• Main utility meters

• Electrical submeters

• Smart meters

• Power-quality meters

• Gas meters

• Thermal-energy meters

• Equipment-level monitoring

• Data collection gateways

• Cloud-based energy dashboards

Submetering can provide more detailed information about individual floors, equipment groups, production areas, or other energy-consuming zones.

Building Automation and Energy Management Systems

A building automation system (BAS) can connect and coordinate building equipment.

Depending on the facility, a BAS may monitor or control:

• Heating and cooling

• Air handling units

• Chillers

• Boilers

• Fans

• Pumps

• Lighting

• Indoor environmental conditions

• Occupancy-related controls

• Equipment schedules

Energy management software can use information from these systems to identify unusual consumption patterns, equipment operation outside scheduled periods, or opportunities for improved control.

HVAC Energy Management

HVAC systems can represent a major portion of commercial building energy use.

Energy-management strategies can include:

• Temperature scheduling

• Occupancy-based controls

• Variable-speed operation

• Economizer management

• Chilled-water optimization

• Heating-system scheduling

• Airflow management

• Equipment sequencing

• Setpoint management

• Preventive maintenance

The appropriate strategy depends on the building's design, climate, occupancy, equipment, and operating requirements.

Energy efficiency should not compromise required ventilation, indoor environmental conditions, safety, or equipment performance.

Lighting and Electrical Management

Lighting management can combine efficient fixtures with automated controls.

Potential approaches include:

• Occupancy sensors

• Daylight controls

• Time-based scheduling

• Dimming

• Lighting-zone management

• Centralized controls

• Electrical load monitoring

Energy monitoring can also help identify unusual electrical consumption and changes in facility operating patterns.

Energy Benchmarking

Benchmarking allows facility managers to compare current performance with historical consumption or comparable buildings.

Important indicators can include:

• Total energy consumption

• Energy-use intensity

• Peak electrical demand

• Energy consumption per floor area

• Consumption by building zone

• Seasonal energy patterns

• Operating-hour consumption

ENERGY STAR Portfolio Manager is a widely used U.S. platform for tracking and benchmarking building energy and water performance.

Benchmarking does not automatically identify the cause of inefficient performance. It is most useful when combined with building-system information and operational analysis.

Demand Management

Commercial facilities may monitor periods of high electricity demand as part of broader energy planning.

Demand-management strategies can include:

• Scheduling flexible equipment

• Coordinating HVAC operation

• Monitoring peak periods

• Managing battery storage where applicable

• Adjusting noncritical loads

• Using automated controls

Facilities should evaluate demand-management strategies against operational requirements and applicable utility arrangements.

Energy Data and Analytics

Modern energy-management platforms can collect large quantities of building data.

Analytics may help identify:

• Unexpected equipment operation

• Abnormal energy consumption

• Simultaneous heating and cooling

• Control problems

• Equipment scheduling issues

• Seasonal performance changes

• Potential maintenance requirements

Trend data can also help facility teams evaluate whether changes in building operation produce measurable improvements.

However, automated alerts should be reviewed in the context of actual building conditions rather than treated as definitive conclusions.

Energy Efficiency Planning

Energy-management data can support longer-term facility planning.

A planning process may include:

1. Establishing a baseline.

2. Identifying major energy-consuming systems.

3. Reviewing operating schedules.

4. Evaluating equipment performance.

5. Identifying potential efficiency measures.

6. Estimating energy impacts.

7. Prioritizing projects.

8. Establishing measurement procedures.

9. Tracking results over time.

This approach can help organizations distinguish between operational adjustments and larger capital projects.

Renewable Energy and Distributed Resources

Commercial energy planning may also consider on-site energy resources.

Depending on the property, these can include:

• Solar photovoltaic systems

• Battery storage

• Combined heat and power

• Electric vehicle charging infrastructure

• Thermal storage

• Demand-response capabilities

Integration with the building's electrical infrastructure should be carefully evaluated because generation and storage can affect load profiles, controls, protection systems, and operating procedures.

Cybersecurity and Connected Building Systems

As more building equipment becomes connected to networks, cybersecurity becomes an important part of energy management.

Energy-management platforms may communicate with building automation systems, meters, sensors, cloud platforms, and other connected technologies.

Basic planning considerations can include:

• User authentication

• Role-based access

• Network segmentation

• Software updates

• Backup procedures

• Access logging

• Vendor access controls

• Data protection

Cybersecurity requirements should reflect the facility's technology architecture and risk profile.

Recent U.S. Energy Management Considerations

U.S. commercial-building energy planning is influenced by federal programs, state policies, utility programs, building energy codes, and local requirements.

The U.S. Department of Energy provides building-efficiency resources, technical information, and energy-management guidance.

State and local jurisdictions may also establish requirements involving energy benchmarking, building performance, disclosure, efficiency improvements, or energy codes.

Federal incentive programs can also change over time. Eligibility and program requirements should therefore be confirmed using current government guidance before financial or facility decisions are made.

Laws, Standards, and Resources

Commercial energy-management planning may reference:

• U.S. Department of Energy building-efficiency resources

• ENERGY STAR Portfolio Manager

• ASHRAE building-performance guidance

• International Energy Conservation Code provisions where adopted

• Local building energy codes

• State energy programs

• Utility demand-management programs

• Applicable electrical and building standards

The requirements applicable to a particular property depend on its location, building type, systems, and jurisdiction.

Tools and Resources

Facility teams may use:

• Smart meters

• Electrical submeters

• Building automation systems

• Energy dashboards

• Temperature and environmental sensors

• Power-quality meters

• Equipment monitoring devices

• ENERGY STAR Portfolio Manager

• Energy benchmarking tools
