EV Charging Infrastructure for Corporate Headquarters: Design, Installation, and Integration Strategies for Commercial Buildings

Building owners should budget approximately 3 to 5 percent of the initial installation cost annually for ongoing maintenance and software subscriptions. This figure increases if the building participates in demand response programs or uses charging revenue to offset operating costs, as these arrangements require higher reliability and uptime guarantees.

The Burns & McDonnell demonstration project at their headquarters represents a replicable model for commercial EV charging infrastructure. By combining open standards technology, thoughtful electrical infrastructure planning, and integration with building energy systems, the project demonstrates how corporate facilities can prepare for the transportation electrification transition. Building owners who adopt similar approaches position their properties to serve current EV-driving occupants while retaining the ability to adapt as technology, regulations, and market conditions evolve.

1. Weekly visual inspection of charging connectors for damage, debris, and corrosion
2. Monthly functional testing of each charging station using a test vehicle or load bank
3. Quarterly inspection of electrical connections for signs of overheating or loosening
4. Semi-annual calibration verification of energy metering components
5. Annual software updates and cybersecurity patches for networked charging equipment

Code Compliance Requirements

EV charging installations must comply with the National Electrical Code, local building codes, and applicable accessibility standards. Building owners should verify that their installation meets NEC Article 625 requirements, including provisions for disconnecting means and ground-fault protection. Many jurisdictions have adopted specific EV charging requirements in their energy conservation codes and standards that mandate minimum charging infrastructure for new construction and major renovations.

Maintenance and Lifecycle Planning

EV charging stations are electromechanical devices exposed to weather, vehicle impact, and frequent connector insertion cycles. A maintenance program that addresses these wear factors extends equipment life and maintains user satisfaction. The SKY platform’s real-time monitoring and fault detection help identify issues before they cause charger downtime, but physical inspection and preventive maintenance remain essential.

Renewable Energy Pairing and Net-Zero Alignment

Corporate headquarters pursuing sustainability certifications increasingly pair EV charging installations with onsite solar generation and battery storage. This pairing converts charging loads from a grid liability into a managed asset that supports the building’s net-zero building design and construction strategies. When solar panels generate excess power during midday hours, that energy can charge employee vehicles rather than being exported to the grid at wholesale rates.

Utility Rate Structure Impacts

Many commercial buildings pay demand charges based on their highest 15-minute power draw during the billing period. Adding EV charging without load management can spike these demand charges, offsetting charging revenue. Building owners must analyze their rate structure and implement load management controls that prevent demand spikes from eroding the financial viability of their charging investment.

Data Collection for Optimization

Networked charging systems generate rich data on usage patterns, energy consumption, charger uptime, and user behavior. As Chris Underwood, General Manager of Burns & McDonnell’s Business & Technology Solutions Division, noted, this data is invaluable for utilities and regulators as they develop new policies, rate structures, and legislation needed as EVs become a larger part of the transportation fleet. For building owners, this data enables continuous optimization of charging operations and supports sustainability reporting.

Installation Best Practices and Lifecycle Management

Successful EV charging infrastructure extends beyond electrical and software components to encompass physical installation and ongoing maintenance. The Burns & McDonnell demonstration integrated Level 2 charging stations across their headquarters campus, requiring coordination between electrical contractors, civil engineers, parking lot designers, and network integrators. Following established best practices helps building owners avoid common pitfalls that delay installations and increase lifecycle costs.

Site Selection and Layout

The physical location of charging stations within a parking facility affects installation cost, user convenience, and maintenance accessibility. Charging stations should be placed near the electrical service entrance to minimize trenching and conduit runs, while also being located where they will be used regularly.

Recommended site selection criteria include:

• Proximity to electrical service: keep conduit runs under 150 feet to avoid voltage drop
• Accessibility compliance: meet ADA requirements for accessible parking spaces with EV charging

Integration with Building Energy Systems and the Grid

Modern EV charging networks do not operate in isolation. The Burns & McDonnell project specifically explored how charging infrastructure integrates with other technology platforms to unlock the benefits of a distributed energy future. This integration spans building energy management, renewable energy generation, energy storage, and utility grid interaction. Building owners who plan for these connections from the outset can optimize energy costs and reduce strain on both building electrical systems and the broader grid.

Demand Management and Load Shifting

Networked EV charging systems offer valuable demand management capabilities. Rather than allowing all chargers to draw full power simultaneously, intelligent load management systems can sequence charging sessions, throttle power during building peak demand periods, and shift charging to off-peak hours when electricity rates are lower. The SKY platform includes advanced grid balancing tools that permit grid operators to control charging networks from a broader energy perspective.

Key demand management strategies include:

• Dynamic load balancing that distributes available capacity across active chargers
• Scheduled charging that prioritizes vehicles with the greatest need or earliest departure times
• Integration with building energy management systems to avoid exceeding utility demand limits
• Participation in utility demand response programs that provide financial incentives for load reduction

As Chris Underwood, General Manager of Burns & McDonnell’s Business & Technology Solutions Division, noted, this data is invaluable for utilities and regulators as they develop new policies, rate structures, and legislation needed as EVs become a larger part of the transportation fleet. For building owners, this data enables continuous optimization of charging operations and supports sustainability reporting.

Installation Best Practices and Lifecycle Management

Successful EV charging infrastructure extends beyond electrical and software components to encompass physical installation and ongoing maintenance. The Burns & McDonnell demonstration integrated Level 2 charging stations across their headquarters campus, requiring coordination between electrical contractors, civil engineers, parking lot designers, and network integrators. Following established best practices helps building owners avoid common pitfalls that delay installations and increase lifecycle costs.

Site Selection and Layout

The physical location of charging stations within a parking facility affects installation cost, user convenience, and maintenance accessibility. Charging stations should be placed near the electrical service entrance to minimize trenching and conduit runs, while also being located where they will be used regularly.

Recommended site selection criteria include:

• Proximity to electrical service: keep conduit runs under 150 feet to avoid voltage drop
• Accessibility compliance: meet ADA requirements for accessible parking spaces with EV charging
• Weather protection: locate stations under canopy cover or specify weather-rated equipment for open lots
• Cable management: use pedestal-mounted systems to reduce tripping hazards and cable damage
• Signage: clearly mark charging spaces to prevent use by non-electric vehicles

Code Compliance Requirements

EV charging installations must comply with the National Electrical Code, local building codes, and applicable accessibility standards. Building owners should verify that their installation meets NEC Article 625 requirements, including provisions for disconnecting means and ground-fault protection. Many jurisdictions have adopted specific EV charging requirements in their energy conservation codes and standards that mandate minimum charging infrastructure for new construction and major renovations.

Maintenance and Lifecycle Planning

EV charging stations are electromechanical devices exposed to weather, vehicle impact, and frequent connector insertion cycles. A maintenance program that addresses these wear factors extends equipment life and maintains user satisfaction. The SKY platform’s real-time monitoring and fault detection help identify issues before they cause charger downtime, but physical inspection and preventive maintenance remain essential.

A comprehensive maintenance program includes:

1. Weekly visual inspection of charging connectors for damage, debris, and corrosion
2. Monthly functional testing of each charging station using a test vehicle or load bank
3. Quarterly inspection of electrical connections for signs of overheating or loosening
4. Semi-annual calibration verification of energy metering components
5. Annual software updates and cybersecurity patches for networked charging equipment

Building owners should budget approximately 3 to 5 percent of the initial installation cost annually for ongoing maintenance and software subscriptions. This figure increases if the building participates in demand response programs or uses charging revenue to offset operating costs, as these arrangements require higher reliability and uptime guarantees.

The Burns & McDonnell demonstration project at their headquarters represents a replicable model for commercial EV charging infrastructure. By combining open standards technology, thoughtful electrical infrastructure planning, and integration with building energy systems, the project demonstrates how corporate facilities can prepare for the transportation electrification transition. Building owners who adopt similar approaches position their properties to serve current EV-driving occupants while retaining the ability to adapt as technology, regulations, and market conditions evolve.

1. Verify OCPP compliance certification for all candidate charging hardware
2. Confirm the network platform supports the required OCPP version (1.6 or 2.0.1)
3. Review integration capabilities with existing building management systems
4. Evaluate data ownership terms to ensure the building owner retains access to usage data
5. Test interoperability between proposed hardware and software before large-scale deployment

Integration with Building Energy Systems and the Grid

Modern EV charging networks do not operate in isolation. The Burns & McDonnell project specifically explored how charging infrastructure integrates with other technology platforms to unlock the benefits of a distributed energy future. This integration spans building energy management, renewable energy generation, energy storage, and utility grid interaction. Building owners who plan for these connections from the outset can optimize energy costs and reduce strain on both building electrical systems and the broader grid.

Demand Management and Load Shifting

Networked EV charging systems offer valuable demand management capabilities. Rather than allowing all chargers to draw full power simultaneously, intelligent load management systems can sequence charging sessions, throttle power during building peak demand periods, and shift charging to off-peak hours when electricity rates are lower. The SKY platform includes advanced grid balancing tools that permit grid operators to control charging networks from a broader energy perspective.

Key demand management strategies include:

• Dynamic load balancing that distributes available capacity across active chargers
• Scheduled charging that prioritizes vehicles with the greatest need or earliest departure times
• Integration with building energy management systems to avoid exceeding utility demand limits
• Participation in utility demand response programs that provide financial incentives for load reduction

Renewable Energy Pairing and Net-Zero Alignment

Corporate headquarters pursuing sustainability certifications increasingly pair EV charging installations with onsite solar generation and battery storage. This pairing converts charging loads from a grid liability into a managed asset that supports the building’s net-zero building design and construction strategies. When solar panels generate excess power during midday hours, that energy can charge employee vehicles rather than being exported to the grid at wholesale rates.

Utility Rate Structure Impacts

Many commercial buildings pay demand charges based on their highest 15-minute power draw during the billing period. Adding EV charging without load management can spike these demand charges, offsetting charging revenue. Building owners must analyze their rate structure and implement load management controls that prevent demand spikes from eroding the financial viability of their charging investment.

Data Collection for Optimization

Networked charging systems generate rich data on usage patterns, energy consumption, charger uptime, and user behavior. As Chris Underwood, General Manager of Burns & McDonnell’s Business & Technology Solutions Division, noted, this data is invaluable for utilities and regulators as they develop new policies, rate structures, and legislation needed as EVs become a larger part of the transportation fleet. For building owners, this data enables continuous optimization of charging operations and supports sustainability reporting.

Building owners who adopt similar approaches position their properties to serve current EV-driving occupants while retaining the ability to adapt as technology, regulations, and market conditions evolve.

Transformer and Switchgear Upgrades

Adding significant EV charging load often necessitates upgrades to the building’s transformers and distribution equipment. Building owners working with an existing transformer nearing capacity may need to replace it with a larger unit or install a dedicated transformer for the charging infrastructure. The switchgear that distributes power to the charging stations must be rated for continuous duty and protected with appropriate overcurrent devices. Proper shielded switchgear for electrical safety becomes particularly important when EV charging circuits are integrated into existing building electrical systems, as these installations involve high continuous currents and frequent load cycling.

Circuit Configuration for Continuous Loads

Each charging station requires a dedicated circuit with appropriate overcurrent protection. The National Electrical Code treats EV charging equipment as continuous loads, meaning the circuit must be rated at 125 percent of the charger’s maximum current draw. A 30-amp Level 2 charger requires a 40-amp circuit. This derating factor compounds when planning multiple stations and must be reflected in the overall panel schedule.

Open Standards and Network Interoperability

The Burns & McDonnell demonstration specifically tested open standards charging technology, a critical distinction in the evolving EV charging landscape. Proprietary charging networks lock building owners into single-vendor ecosystems, limiting their ability to switch hardware, software, or service providers as technology improves. Open standards ensure that charging stations from different manufacturers can communicate with network management platforms from different vendors, creating flexibility and competition in the marketplace.

Key Standards for Commercial EV Charging

The Greenlots SKY platform used in the Burns & McDonnell project exemplifies how open-standards software integrates charging infrastructure with other building technology platforms, providing real-time monitoring, fault detection, and flexible pricing tools on protocols that allow interoperability with diverse hardware and utility systems.

Steps to Avoid Vendor Lock-In

Building owners should specify OCPP-compliant charging stations as a baseline requirement. This preserves the ability to switch network management providers later without replacing hardware. The process for selecting an open-standards system involves several steps:

1. Verify OCPP compliance certification for all candidate charging hardware
2. Confirm the network platform supports the required OCPP version (1.6 or 2.0.1)
3. Review integration capabilities with existing building management systems
4. Evaluate data ownership terms to ensure the building owner retains access to usage data

As Chris Underwood, General Manager of Burns & McDonnell’s Business & Technology Solutions Division, noted, this data is invaluable for utilities and regulators as they develop new policies, rate structures, and legislation needed as EVs become a larger part of the transportation fleet. For building owners, this data enables continuous optimization of charging operations and supports sustainability reporting.

Installation Best Practices and Lifecycle Management

Successful EV charging infrastructure extends beyond electrical and software components to encompass physical installation and ongoing maintenance. The Burns & McDonnell demonstration integrated Level 2 charging stations across their headquarters campus, requiring coordination between electrical contractors, civil engineers, parking lot designers, and network integrators. Following established best practices helps building owners avoid common pitfalls that delay installations and increase lifecycle costs.

Site Selection and Layout

The physical location of charging stations within a parking facility affects installation cost, user convenience, and maintenance accessibility. Charging stations should be placed near the electrical service entrance to minimize trenching and conduit runs, while also being located where they will be used regularly.

Recommended site selection criteria include:

• Proximity to electrical service: keep conduit runs under 150 feet to avoid voltage drop
• Accessibility compliance: meet ADA requirements for accessible parking spaces with EV charging
• Weather protection: locate stations under canopy cover or specify weather-rated equipment for open lots
• Cable management: use pedestal-mounted systems to reduce tripping hazards and cable damage
• Signage: clearly mark charging spaces to prevent use by non-electric vehicles

Code Compliance Requirements

EV charging installations must comply with the National Electrical Code, local building codes, and applicable accessibility standards. Building owners should verify that their installation meets NEC Article 625 requirements, including provisions for disconnecting means and ground-fault protection. Many jurisdictions have adopted specific EV charging requirements in their energy conservation codes and standards that mandate minimum charging infrastructure for new construction and major renovations.

Maintenance and Lifecycle Planning

EV charging stations are electromechanical devices exposed to weather, vehicle impact, and frequent connector insertion cycles. A maintenance program that addresses these wear factors extends equipment life and maintains user satisfaction. The SKY platform’s real-time monitoring and fault detection help identify issues before they cause charger downtime, but physical inspection and preventive maintenance remain essential.

A comprehensive maintenance program includes:

1. Weekly visual inspection of charging connectors for damage, debris, and corrosion
2. Monthly functional testing of each charging station using a test vehicle or load bank
3. Quarterly inspection of electrical connections for signs of overheating or loosening
4. Semi-annual calibration verification of energy metering components
5. Annual software updates and cybersecurity patches for networked charging equipment

Building owners should budget approximately 3 to 5 percent of the initial installation cost annually for ongoing maintenance and software subscriptions. This figure increases if the building participates in demand response programs or uses charging revenue to offset operating costs, as these arrangements require higher reliability and uptime guarantees.

The Burns & McDonnell demonstration project at their headquarters represents a replicable model for commercial EV charging infrastructure. By combining open standards technology, thoughtful electrical infrastructure planning, and integration with building energy systems, the project demonstrates how corporate facilities can prepare for the transportation electrification transition. Building owners who adopt similar approaches position their properties to serve current EV-driving occupants while retaining the ability to adapt as technology, regulations, and market conditions evolve.

As electric vehicle adoption accelerates across the United States, commercial property owners and corporate facility managers face a pressing question: how to design and install EV charging infrastructure that meets current needs while remaining adaptable for future technology. The engineering firm Burns & McDonnell recently demonstrated one approach by partnering with Greenlots to build an advanced EV charging network at their headquarters, testing open standards charging technology that could reshape how commercial buildings integrate transportation electrification. This demonstration project illustrates the technical and operational considerations that building professionals must address when incorporating EV charging into their properties. Beyond simple installation, successful implementation requires careful planning around electrical capacity, intelligent building technology integration, grid interaction, and long-term scalability.

Electrical Infrastructure Requirements for EV Charging Stations

The foundation of any commercial EV charging installation is the electrical infrastructure that delivers power from the utility grid to the charging equipment. Unlike residential installations that typically draw from existing panel capacity, commercial installations often require substantial electrical upgrades that must be coordinated with the building’s overall power distribution system.

Load Calculation and Capacity Planning

Every EV charging installation begins with a thorough load calculation that accounts for the building’s existing electrical demand, the additional load from charging stations, and anticipated usage patterns. The Burns & McDonnell project incorporated networked Level 2 charging stations, each capable of fully charging a vehicle in four to six hours. Level 2 chargers typically draw between 3.3 kW and 19.2 kW per unit, meaning a bank of 20 stations could add 66 kW to 384 kW of load to the building’s electrical system.

Key considerations for load planning include:

• Existing service capacity and available headroom in the main switchboard
• Peak demand periods and the building’s daily load profile
• Load management strategies such as sequential or scheduled charging
• Future expansion allowances for additional stations or higher-power chargers
• Local utility requirements for interconnection agreements

Transformer and Switchgear Upgrades

Adding significant EV charging load often necessitates upgrades to the building’s transformers and distribution equipment. Building owners working with an existing transformer nearing capacity may need to replace it with a larger unit or install a dedicated transformer for the charging infrastructure. The switchgear that distributes power to the charging stations must be rated for continuous duty and protected with appropriate overcurrent devices. Proper shielded switchgear for electrical safety becomes particularly important when EV charging circuits are integrated into existing building electrical systems, as these installations involve high continuous currents and frequent load cycling.

Circuit Configuration for Continuous Loads

Each charging station requires a dedicated circuit with appropriate overcurrent protection. The National Electrical Code treats EV charging equipment as continuous loads, meaning the circuit must be rated at 125 percent of the charger’s maximum current draw. A 30-amp Level 2 charger requires a 40-amp circuit. This derating factor compounds when planning multiple stations and must be reflected in the overall panel schedule.

Open Standards and Network Interoperability

The Burns & McDonnell demonstration specifically tested open standards charging technology, a critical distinction in the evolving EV charging landscape. Proprietary charging networks lock building owners into single-vendor ecosystems, limiting their ability to switch hardware, software, or service providers as technology improves. Open standards ensure that charging stations from different manufacturers can communicate with network management platforms from different vendors, creating flexibility and competition in the marketplace.

Key Standards for Commercial EV Charging

The Greenlots SKY platform used in the Burns & McDonnell project exemplifies how open-standards software integrates charging infrastructure with other building technology platforms, providing real-time monitoring, fault detection, and flexible pricing tools on protocols that allow interoperability with diverse hardware and utility systems.

Steps to Avoid Vendor Lock-In

Building owners should specify OCPP-compliant charging stations as a baseline requirement. This preserves the ability to switch network management providers later without replacing hardware. The process for selecting an open-standards system involves several steps:

1. Verify OCPP compliance certification for all candidate charging hardware
2. Confirm the network platform supports the required OCPP version (1.6 or 2.0.1)
3. Review integration capabilities with existing building management systems
4. Evaluate data ownership terms to ensure the building owner retains access to usage data
5. Test interoperability between proposed hardware and software before large-scale deployment

Integration with Building Energy Systems and the Grid

Modern EV charging networks do not operate in isolation. The Burns & McDonnell project specifically explored how charging infrastructure integrates with other technology platforms to unlock the benefits of a distributed energy future. This integration spans building energy management, renewable energy generation, energy storage, and utility grid interaction. Building owners who plan for these connections from the outset can optimize energy costs and reduce strain on both building electrical systems and the broader grid.

Demand Management and Load Shifting

Networked EV charging systems offer valuable demand management capabilities. Rather than allowing all chargers to draw full power simultaneously, intelligent load management systems can sequence charging sessions, throttle power during building peak demand periods, and shift charging to off-peak hours when electricity rates are lower. The SKY platform includes advanced grid balancing tools that permit grid operators to control charging networks from a broader energy perspective.

Key demand management strategies include:

• Dynamic load balancing that distributes available capacity across active chargers
• Scheduled charging that prioritizes vehicles with the greatest need or earliest departure times
• Integration with building energy management systems to avoid exceeding utility demand limits
• Participation in utility demand response programs that provide financial incentives for load reduction

Renewable Energy Pairing and Net-Zero Alignment

Corporate headquarters pursuing sustainability certifications increasingly pair EV charging installations with onsite solar generation and battery storage. This pairing converts charging loads from a grid liability into a managed asset that supports the building’s net-zero building design and construction strategies. When solar panels generate excess power during midday hours, that energy can charge employee vehicles rather than being exported to the grid at wholesale rates.

Utility Rate Structure Impacts

Many commercial buildings pay demand charges based on their highest 15-minute power draw during the billing period. Adding EV charging without load management can spike these demand charges, offsetting charging revenue. Building owners must analyze their rate structure and implement load management controls that prevent demand spikes from eroding the financial viability of their charging investment.

Data Collection for Optimization

Networked charging systems generate rich data on usage patterns, energy consumption, charger uptime, and user behavior. As Chris Underwood, General Manager of Burns & McDonnell’s Business & Technology Solutions Division, noted, this data is invaluable for utilities and regulators as they develop new policies, rate structures, and legislation needed as EVs become a larger part of the transportation fleet. For building owners, this data enables continuous optimization of charging operations and supports sustainability reporting.
