U.S. Army Corps of Engineers (USACE) ECIP SolarWalls®

Tooele Army Depot, Utah

For the Tooele Army Deport ECIP SolarWalls® project, E-Corp worked directly with Conserval, the proprietor of the SolarWall® technology, to place approximately 11,250 square feet of solar panel on the walls of 11 buildings—spread out across Tooele Army Depot—and tie these panels into air handling units (AHUs) inside the buildings. SolarWall technology is a solar air heating system that heats building ventilation air and improves indoor air quality. SolarWall® systems deliver huge life-cycle cost savings.

At the start of the project, E-Corp identified one of the original buildings in the statement of work (SOW) as a poor candidate for the SolarWall® system. We proposed another building for the system and were able to provide SolarWalls® for the new building, complete with design and without additional costs to the government.

The scope of work included the following:

  • Penetrating the wall between the air intake locations
  • Ducting the heated air into the building (using insulated duct) where E-Corp installed a damper and a DDC control system to control the solar-heated air between the two air handling units
  • Installing SolarWalls® on buildings 507, 509, 510, 519, 594, 1236, 1261, 1265, 1267, 1376, and 1400
  • Adding a single-stage and a two-stage SolarWall® system

Despite the project being spread out over a large geographic area, E-Corp successfully installed SolarWalls® for the USACE on time and on budget.
