From the outside, designing a data center might seem straightforward: build a structure, plug in some servers, and ensure its connected to the internet. However, anyone who has ever worked within or on a data center knows the reality is far more complex. Data center design is a nuanced, high-stakes process that involves balancing reliability, scalability, energy efficiency, safety, and cost—all while staying ahead of evolving technologies and regulations.
In this comprehensive guide of gbc engineers, we'll delve into the most common data center design challenges that professionals face today. Understanding these obstacles not only helps you avoid common mistakes but also ensures your facility can meet both current demands and future growth.
Power and Cooling Challenges
Power and cooling are two of the most critical components in data center design. As data centers evolve to handle higher processing demands, they require denser hardware configurations and, consequently, more power.
Key Power Challenges:
Selecting an electrical system that supports high scalability and performance
Managing increased power consumption due to high-density server racks
Ensuring robust power distribution and redundancy to prevent outages
Addressing arc flash risks that rise with increased power loads
Cooling Challenges:
Equipment density leads to excessive heat output
Traditional HVAC systems may not suffice for modern energy-intensive setups
High heat levels can result in equipment malfunction or failure
To tackle these challenges, many data centers adopt modular and scalable designs that offer flexibility and allow for efficient cooling strategies. This includes using hot/cold aisle containment, liquid cooling, or immersion cooling systems. The goal is to maintain optimal temperatures while minimizing energy consumption and cost.

Scalability and Futureproofing
Scalability is vital in today’s data-driven world. As data creation is expected to exceed 180 zettabytes by 2025, data centers must be ready to handle massive increases in storage, processing, and network demands.
Common Scalability Issues:
Physical space constraints
Limitations in existing power and cooling infrastructure
Inability to adapt to new technologies or workloads
Futureproofing Solutions:
Use of modular infrastructure that grows with demand
Integration of virtualization and software-defined networking (SDN)
Design flexibility that allows for phased capacity additions
By incorporating these strategies, data centers can scale cost-effectively while reducing the environmental footprint and mitigating operational risks.
Energy Efficiency and Sustainability
With the growing global emphasis on sustainability, data centers face pressure to reduce energy consumption and environmental impact.
Why It Matters:
Hyperscale data centers can use as much energy as 80,000 homes
Regulatory bodies in countries like Singapore and the Netherlands are enforcing sustainability measures
Green certifications like LEED are becoming industry standards
Sustainability Challenges:
Integrating renewable energy sources
Managing energy in high-density environments
Implementing energy-efficient lighting, hardware, and cooling systems
Expert Insight:
"Adopting a sustainability-first approach to data center design and operation is the best way to future-proof your facilities while aligning with both current and future sustainability standards." – Victoria Steventon Paterson, Global Arc Flash Manager, Skanwear
Designing an energy-efficient data center often involves higher upfront investment but yields long-term cost savings and operational efficiency.

Facility Constraints
Facility limitations are among the most persistent challenges in data center design.
Common Constraints:
Limited physical space in urban or pre-existing buildings
Geographical limitations (seismic zones, flooding risk, etc.)
Retrofitting older facilities with modern equipment
When upgrading existing data centers, major elements like HVAC systems and electrical infrastructure may need to be replaced entirely. Additionally, newer equipment often demands more power and increases arc flash risks due to complex electrical setups.
Best Practices:
Conduct thorough arc flash and facility risk assessments
Plan layouts to optimize airflow and minimize electrical hazards
Incorporate safety upgrades alongside performance enhancements
Decentralization and Edge Computing
The rise of edge computing is decentralizing traditional data center models. Instead of centralized, monolithic facilities, we're seeing a move toward distributed data centers located closer to end users.
Decentralization Benefits:
Lower latency
Improved responsiveness
Enhanced user experience for time-sensitive applications
Challenges Introduced:
Managing distributed infrastructure at scale
Ensuring consistent performance and uptime across multiple sites
Addressing physical security and redundancy needs
To address these, designers must adopt scalable, modular architectures and automated monitoring systems that provide visibility across all nodes in the network.

Cost Management
Designing and building a data center is a capital-intensive endeavor. From equipment and materials to labor and logistics, managing costs effectively is a major hurdle.
Cost Challenges:
Supply chain volatility and component shortages
Rising prices for skilled labor and raw materials
Inaccurate budgeting and cost estimation
Strategies for Cost Control:
Detailed project planning and transparent cost tracking
Budgeting buffers for unexpected expenses
Partnering with experienced vendors and consultants to avoid costly missteps
An agile, well-documented cost management plan ensures that your data center project remains on time and within budget.
Compliance and Regulatory Requirements
Compliance is non-negotiable in data center design. Facilities must adhere to a host of local and international standards governing safety, environmental impact, energy usage, and data security.
Major Compliance Areas:
Fire safety and emergency planning
Environmental regulations
Data privacy and cybersecurity (e.g., GDPR, HIPAA)
Occupational safety standards (including arc flash compliance)
Failing to meet these standards can result in fines, shutdowns, and long-term reputational damage. Involving legal and compliance experts early in the design process is a smart way to stay ahead of potential issues.

Security Considerations
Physical and digital security must be at the forefront of any data center design.
Physical Security Challenges:
Unauthorized access prevention
Perimeter fencing, surveillance, and biometric entry systems
Redundant systems for power, cooling, and fire suppression
Cybersecurity Design Considerations:
Segmentation of networks
Infrastructure support for real-time threat monitoring
Robust backup and recovery systems
A secure-by-design approach ensures your facility is prepared for both physical intrusions and cyberattacks.
Staffing and Operational Expertise
Building the data center is only half the battle; operating it efficiently requires skilled personnel.
Staffing Challenges:
Finding technicians with up-to-date knowledge in networking, power systems, and HVAC
Ensuring 24/7 monitoring and response capabilities
Ongoing training to keep pace with evolving technologies
Incorporating automation, remote management tools, and AI-driven monitoring can help alleviate staffing burdens and improve operational efficiency.
