Data centers

We are proud to design, build and operate some of the most sustainable data centers in the world.

Data centers power the internet, making digital communication and connection possible. They also account for the highest percentage of Meta’s energy use, water use and GHG emissions.

We can have the largest impact on our overall emissions reductions by designing, building and operating some of the most sustainable data centers in the world. Data center buildings we completed in 2021 exhibit a Power Usage Effectiveness (PUE) of 1.09 and Water Usage Effectiveness (WUE) of 0.26.

For the Earth

Efficiency and renewable energy are key components of our approach to designing, building and operating sustainable data centers. We have 33 certified LEED Gold data centers totaling more than 19 million square feet, six of which earned the designation in 2022.

Each data center site is designed to promote biodiversity, native plants and adaptive landscapes that mimic the natural hydrology of the region to help reduce urban heat island effect. We choose plant species, efficient irrigation and alternative water sources when available in addition to Forestry Stewardship Council (FSC)-certified new wood products and smart scheduling technologies that together save more than 80 million gallons of water per year.

For our people

With each new data center, we strive to improve sustainability, inclusiveness and comfort for our Metamates. These efforts include:

  • Reducing indoor air contaminants, resulting in  lower absenteeism and increased productivity
  • Improving interior acoustics for better privacy and concentration as well as improved lighting for better visibility
  • Following LEED guidelines to increase fresh air by 30% to improve cognition
  • Maximizing natural light and views to outdoor landscaping

Case study

Optimizing humidity for efficient water use

In 2021, we identified winter humidification as an opportunity to improve operating efficiency by optimizing our relative humidity (RH). We piloted an RH adjustment at our data center in Los Lunas, New Mexico, and found by lowering our current 20% minimum RH to 13% minimum RH, we were able to reduce water use by 40% over nine months.

Since then, we have begun to implement this change across existing data centers, while new construction will reduce water use 10% to 65% annually

Data center water efficiency

Because data centers rely on water to cool servers and maintain humidity levels, our teams are always looking for ways to reduce our water use. One method we use to conserve water is through direct evaporative cooling, which relies on outside air.

Traditional technologies, like chilled water plants and cooling towers, rely on water to reject heat. In areas facing specific environmental challenges, such as high levels of dust, extreme humidity or elevated salinity, using direct cooling could severely impact IT equipment.

In these cases, we use indirect cooling systems to minimize the risk to our buildings and the servers housed within. In partnership with Nortek Air Solutions, we have developed an indirect cooling technology, called the StatePoint Liquid Cooling (SPLC) system. The first of its kind to be deployed to data centers, the system uses less water than a typical indirect cooling system because it uses air to cool water instead of using water to cool air.

Sustainability impact map

We are committed to creating a positive impact on the communities where we operate. That is why all of our renewable energy projects are interconnected to the same electric grid as our facilities. This map highlights our renewable energy procurement and deployment efforts worldwide, water stewardship efforts in the communities we operate in, and other sustainability features across our global portfolio of data centers.
