Sustainability

Environmental Concerns 

Data centers face increasing criticism for their energy and water consumption, drawing attention to their environmental impact. With the energy-sector responsible for roughly 10% of global freshwater withdrawls, the mission-critical sector is under growing pressure to improve energy efficiency and adopt renewable energy to meet sustainability goals. Meeting these demands requires advanced cooling technologies, optimized power usage effectiveness (PUE), and clean energy adoption. Sustainable solutions are critical to balancing the need for increased computing power with reduced carbon footprints and public demand for greener practices.

SIDE Solution

The Resilience Series provides a sustainable solution that reduces carbon emissions, with each campus designed to progress toward a zero-carbon footprint over time. Overwatch Capital’s low PUE design and waste heat capture allow the company to match or exceed the grid standards of carbon intensity. For tenants seeking decarbonization, Overwatch Capital procures renewable natural gas attributes, as well as a series of other fuel inputs that optimize tenant environmental objectives. Future campuses in the Resilience Series will further reduce emissions by developing waste-to-energy solutions for renewable gas and clean electricity.

 

The Resilience Series optimizes water resources through advanced cooling technologies, including adiabatic air cooling, liquid cooling, and direct-to-chip cooling. These systems are selected based on regional factors such as climate, available space, and water resources, allowing for flexibility in deployment. Adiabatic air cooling minimizes water and energy consumption by leveraging evaporative cooling, offering a sustainable alternative to traditional methods. Liquid cooling enables efficient heat removal from high-density compute environments by circulating coolant close to the source, reducing reliance on traditional air systems and enhancing overall energy performance. Direct-to-chip cooling enhances efficiency by delivering liquid coolant directly to heat-generating components, improving thermal management and supporting higher rack densities. The Resilience Series uses advanced cooling methodologies depending on region, climate, space, water, etc., and is adaptable in which type to use to deliver low PUEs.
