General Motors installed 580 kW of solar to the roof of its e-Motor building at its Baltimore, Maryland, operations complex.
Together with an existing 1.23 MW solar array on its grounds, six percent of the facility’s electricity now comes from renewable sources. Maryland-based Empower Energies installed the solar system.
The US Green Building Council certified the building as LEED Silver for environmental upgrades such as the solar array, installing LED exterior lighting and using compact fluorescent lighting in production areas.
Employee efforts to further reduce the building’s carbon footprint led to its surpassing the voluntary EPA ENERGY STAR Challenge for Industry, which requires a 10 percent reduction in energy intensity within five years.
