Bloomingdale’s Year of Major Energy Efficiency

POSTED UNDER Energy & Lighting

For quite some time, the buzz circulating through Macy’s Energy Services has been about one major energy-efficient aspect of the company – Bloomingdale’s. In the past year, the store “like no other” outperformed Macy’s stores in energy reduction. We sat down with Michael Nesmith of Energy Services and Jose Herrero from Bloomingdale’s to get the story behind the company’s success.

In 2014 alone, Bloomingdale’s increased overall energy efficiency by more than six percent. In the energy services world, this number is huge, especially within the scope of only one year. Bloomingdale’s saved 8,186,234 Kwh worth of energy – which is enough energy to provide electricity to 776 average American homes for one year.

So how is Bloomingdale’s making such great strides toward energy reduction? Two major initiatives were implemented to make a substantial difference.

First, several LED lighting retrofits were put in place, including replacement of 25 watt metal halides and 47 watt halogen lamps with 14 or 17 watt LED lamps.

Second, bi-monthly calls were set up between Energy Services and Bloomingdale’s engineers, opening communication and collaboration between departments. Trend data from Energy Services was put in the hands of the engineers and feedback was shared on building performance. Any issues causing energy inefficiency were quickly addressed. These calls put building engineers in the driver’s seat to make a big difference by optimizing energy usage in their store.

Bloomingdale’s has had an impressive year for energy efficiency … so what’s next?

Bloomingdale’s will continue calls with Energy Services, as this collaboration will keep the momentum rolling on these initiatives. Additionally, Bloomingdale’s will investigate several energy saving programs including:

  • Monitoring escalator start/stop time
  • Lighting retrofits in two high-energy rate locations (Boston and California)
  • Energy management system upgrade at the 59th Street location, helping the flagship store to operate as efficiently as possible

2014 was a monumental year for Bloomingdale’s energy efficiency. Time and time again we’re seeing the benefits of cross-departmental collaboration. We can’t wait to see the progress made in 2015!
