Protecting God's blessings

Our Catholic faith teaches us to care for God's creation, and the design, construction and operation of our campus reflects this commitment. We are proud to have ENERGY STAR certification and we also appreciate the economic benefits this brings to our community.

In recognition of superior energy performance, the U.S. Environmental Protection Agency awarded Eastside Catholic School ENERGY STAR certification in 2012. Buildings that earn the EPA's ENERGY STAR rating use 35 percent less energy and generate 35 percent fewer greenhouse gas emissions than similar buildings across the nation.
