The conversation around data centers is changing.
As demand for digital infrastructure continues to accelerate, driven by cloud computing and the exponential growth of data, owners and communities alike are asking more difficult questions about environmental impact, energy use and long-term sustainability. Historically, mission critical facilities have been viewed as incompatible with high-performance sustainability standards. Granger’s experience with enterprise data centers proves otherwise.
Across multiple markets and owners, Granger has successfully designed and constructed five LEED‑certified data centers, demonstrating that reliability and environmental responsibility are not competing priorities. With the right approach, data centers can meet stringent operational requirements while achieving meaningful sustainability outcomes.
Delivering LEED Performance in a Mission Critical Environment
LEED (Leadership in Energy and Environmental Design) is the world’s most widely-used, voluntary green building rating system, developed by the U.S. Green Building Council (USGBC). It provides a framework for healthy, efficient and cost-saving green buildings. LEED certification verifies environmental sustainability in design, construction, operation and maintenance, promoting lower energy/water usage and healthier indoor environments. There are 1,721 LEED-certified and registered data centers as of December 2025.
LEED was intentionally developed to address high‑intensity building types, including data centers, with rating system adaptations designed to account for their unique energy, cooling and operational demands. Experience delivering LEED‑certified data centers developed a clear understanding of how to apply these frameworks in mission critical environments without compromising reliability or resiliency.
Across five LEED‑certified data center projects—four achieving LEED Gold and one LEED Silver— the project teams aligned design intent, system performance and construction execution with LEED requirements from the start. Sustainability strategies were embedded into early planning decisions, allowing teams to pursue efficiency gains while maintaining the redundancy and uptime essential to mission critical operations.
Through close coordination with design partners, these efforts have contributed to facilities achieving Power Usage Effectiveness (PUE) values as low as 1.133, well below industry averages. For context, the average data center PUE commonly ranges around 1.55, while a PUE of 1.2 or lower is considered highly efficient.
These outcomes demonstrate that LEED certification is compatible with and reinforced by efficient, well-executed mission‑critical facilities.
Energy Efficiency that Exceeds Industry Norms
Energy efficiency is one of the most cited challenges in sustainable data center development. Mission critical projects like these directly address this challenge through design coordination, constructability expertise and data-driven decision-making.
Reaching the suitability benchmarks, such as the PUE, requires a deliberate focus on system optimization, including:
- Evaluating multiple mechanical system configurations and redundancy strategies
- Supporting energy-efficient cooling approaches aligned with local climate conditions
- Analyzing energy tradeoffs early to inform owner decisions with clear cost, risk and performance implications
Rather than prescribing a single solution, this approach facilitates informed decision-making by presenting owners with clear, comparative options that balance cost, operational efficiency, resiliency and long-term value.
Construction Decisions that Support Long-Term Performance
Sustainable outcomes in data centers are not achieved through design alone. Construction means and methods play a critical role in reducing environmental impact while protecting long-term operational reliability.
On one recent project located on a former industrial landfill site, the team implemented construction strategies that resulted in minimizing disruption to existing environmental controls, reducing landfill waste and protecting site integrity. Extensive water management systems were installed to manage groundwater responsibly, and dynamic replacement techniques were used in lieu of deep foundations, significantly reducing soil disturbance and material intensity. These decisions supported both LEED objectives and owner sustainability goals without compromising onsite health or safety.
Sustainability as a Shared Responsibility
The need for data centers will only continue to grow. With that growth comes increased responsibility—both to owners investing in long-term assets and to the communities in which these facilities are built.
Granger views sustainability not as an aesthetic or optional feature, but as a core obligation of modern mission critical delivery. By working closely with clients, architects, engineers and local jurisdictions from the earliest stages, teams can support designs that maximize energy efficiency, minimize water usage and reduce environmental impact.
This collaborative approach ensures sustainability strategies are integrated holistically rather than applied retrospectively, resulting in facilities that perform efficiently from day one and remain resilient over decades of operation.
Dispelling the Myth: Sustainable Data Centers are Achievable
One of the most persistent misconceptions is that data centers cannot realistically meet high sustainability standards. Granger’s experience demonstrates that assumption is outdated.
Granger has shown that mission‑critical facilities can be designed and built to meet the strict guidelines required for LEED certification through repeatable construction strategies, documented processes and proven energy performance metrics across five LEED‑certified data centers and counting. These projects stand as proof points that sustainability and mission critical performance are not mutually exclusive, but mutually reinforcing.
The biggest concerns with new data center construction include massive energy consumption straining power grids, high water usage for cooling (often in water-stressed regions), increased carbon emissions and noise pollution. LEED certification addresses these by mandating energy efficiency, water conservation, sustainable materials and reduced environmental impact.
As the industry evolves, owners seeking next-generation data centers must demand partners who can navigate both operational complexity and environmental responsibility. Granger’s mission critical experience shows what is possible when sustainability is treated not as a constraint, but as a design and construction imperative.
