State Department Uses Smart Building Tech to Significantly Cut Energy Usage

The agency makes its embassies more efficient and helps model the technology for foreign host countries.

The State Department replaced a 23-year-old dimming system running on a floppy disk drive and replaced it with a modern smart energy system. 

The agency installed an electrical monitoring system for its headquarters building in Washington, D.C., that has about 60,000 points that it monitors for energy usage, according to Tom Berringer, chief electrician for the State Department. 

The effort is part of a larger one at the State Department to install smart building technologies at not only its main headquarters but at embassies around the globe. The agency is using Internet of Things sensors, smart meters and monitoring tools to dramatically cut its energy usage and carbon footprint. 

“The reason we use smart meters initially started out for tracking what our energy use was and tracking our baseline of activities,” says Landon Van Dyke, the acting deputydirector of the Center for Analytics. “Because of smart metering, we’re able to address things like energy efficiency and resource efficiency, but we’re also doing resiliency and more reliability in the services that we’re providing at the embassies.”

State Department Uses Smart Meters to Monitor Energy Usage Abroad

Smart buildings rely on internet-connected advanced utility meters to measure utility use (such as electrical power and natural gas or water use) in real time. They also use software to collect and analyze data from advanced meters, which can then be used to alert building staff to potential problems. 

The State Department’s reach sprawls across the world, with 190 missions and posts in 274 total cities. “The operating conditions are vastly different from country to country,” Van Dyke says.

For example, in Mongolia, the building embassy staff worked out of was an old Soviet-era building where staff didn’t have any control over the amount of heat that would come in. “It was negative 40 outside and people wanted to open the windows because we were sweating,” says Leila Tabor, former facilities manager for the U.S. embassy in Ulaanbaatar, Mongolia. 

“One of the things that we wanted to do with the smart metering program was to give the embassy as much independence as possible,” Van Dyke says. 

The State Department can have engineers in Washington “peek in and take a look at what’s going on in Africa and not have to send a quarter million dollars’ worth of engineers over to a post to take a look,” he says. 

Back in Foggy Bottom, the department uses a smart energy Eaton Foreseer Monitoring System. “It’s very good at looking at large groups of data,” says Berringer. “We look at the main power coming in, we look at our emergency power system very carefully. We look at critical power, which is used for computer rooms and special areas.”

State Department Models Smart Building Tech for Host Countries

The State Department started out with a blank slate for its smart meter platform, according to Van Dyke, because all its embassies “are from different years and have a slew of different technologies.”

The agency had to create a platform that was technology agnostic. “New technologies, new interfaces always come out, and we wanted to make sure that we were future-proofing the ability to grab energy and interpret it,” Van Dyke says. 

Many host countries will tell embassy staff and diplomats that they cannot install smart meter technology because their power grid and internet service are unreliable, according to Van Dyke. 

“Many times, we have our officers in the field say, ‘Did you realize that this building here at the American embassy is a smart building?’” he says. “And they can demonstrate how the technology is already active in their country. It was definitely an unexpected success to have our embassies be a model of how we can address environmental issues and energy efficiencies.”
