Overview of Project

ES2 had the opportunity to work on its first, but not last, international project for the Air Force at the Misawa Air Base in Japan. Located in Misawa, Aomori Prefecture of Japan. The Misawa Air Base was built in 1938 and has seen use throughout World War II, Korean War, Cold War, Global War on Terror, and current day. Today it is the only joint service installation in the western Pacific and is used by the Japan Air Self-Defense Force, the United States Air Force, United States Army, and the United States Navy. The base houses 5,200 US military personnel, 350 US civilian employees, and 900 Japanese national employees.

This $206 million Energy Savings Performance Contract (ESPC) was awarded to Trane who brought in ES2 to perform the Commissioning for this project. The project scope includes:

700 diverse, mixed-use, and highly-secured buildings totaling nearly 8M Sq. Ft. The primary elements of the ESPC are electrical power generation and steam production. The power generation will be provided via installation of 7.5 MW DC of Solar PV, 6.5 MW AC of CHP, a cyber secure microgrid allowing Island Operation, a LNG Satellite Plant, and on-base natural gas distribution. (Trane 2020)

ES2’s role in this project included overseeing multiple building automation system upgrades & VFDs as well as a liquid natural gas plant and solar field. There was a total of 136 buildings with upgraded BAS systems that had to be commissioned. The liquid natural gas facility was a unique design that required a detailed testing procedure. The amount of detail included in this project required ES2’s Professional Engineers and NEBB Certified Professionals to develop and implement the testing procedures. With this project taking place on a joint US and Japanese military base it required our team members to receive the proper clearance to work and operate on the base.

The goal of the project was to create a source of renewable and redundant energy in case of a natural disaster such as a tsunami. The second goal was to use the upgraded BAS and VFDs to reduce the general energy cost and upgrade the building’s efficiency.

As with any project there can be setbacks. With a project that is on the other side of the world it is inevitable that difficulties can arise. Our team had to overcome language barriers as they worked with Japanese engineers on both the solar field and the liquid natural gas plant. Traveling logistics were made more difficult as a large part of this project took place during the Pandemic. Our team members also had to learn how to drive on the left side of the road while battling 3 ft of snow in blizzard conditions.
