Ypsilanti’s Gilbert Residence: Saving Energy and Water

Clean Energy Coalition, through the Rebuild Ypsilanti program, conducted an energy audit for the Gilbert Residence, a 43,000-square-foot continuing care facility in Ypsilanti, Mich. The energy audit identified a variety of ways the residence could conserve energy and water, and Gilbert’s managers followed the advice, adding insulation, efficient lighting fixtures, and low-flow showerheads, faucets and toilets.

Assessment Findings

  • Lack of adequate insulation
  • Outdated water fixtures
  • Outdated lighting

Improvements made

  • Insulation added in attic
  • Hot water pipe wrap
  • 90 dual flush toilets
  • Low flow faucets and showerheads
  • Upgraded T12 fluorescent light fixtures to more efficient T8
  • Lighting sensors


  • Received $2,800 in incentives
  • Buildings stay warmer in winter, more comfortable for residents
  • Heating energy reduced by 40% for electricity and 20% for natural gas
  • Water usage reduced by 20%

Gilbert Residence is now saving an estimated $30,000 annually (some 27 percent of its previous yearly utility expenses). But the savings didn’t stop there. In 2010, Rebuild Ypsilanti audited more than 100,000 square feet and saved a total of $50,000 in energy costs and water savings.
