… Expert advice. “So I knew what we had, but I didn’t know where we could go,” says McGinnis. He turned to En-Power, the energy consultant 2 Charlton had used for other efficiency projects, for next-step advice. En-Power double-checked the math and recommended a bi-level LED fixture manufactured by Remphos. This fixture would dim the lights when no one was in the hallway; but as soon as someone entered, the lights would brighten to full strength.

That’s why energy gurus talk about how much time it will take to see a return on your investment. The total project cost about $42,450. ConEd gave them a rebate of $12,900, and the co-op wrote a check for $30,000. Each year the co-op will be saving about $9,000 in electricity charges, bringing their payback period to about 2.4 years.”
