Raising the Sustainability Bar

Posted on by

Following an assessment of the light bulbs used in their restaurants, The Cheesecake Factory completed a re-lamp in each restaurant by installing low wattage bulbs. This reduces their kilowatt usage by 2% to 3% each year based on a standard 10,000 square foot restaurant. In addition, they are upgrading their lighting to more energy efficient products as they become available, and are currently testing new LED lighting to replace neon lights, which are currently being used in certain areas of their restaurants.

Prestigious Princeton Sees the LED Light

Posted on by

One of America’s most prestigious universities is in the middle of an ambitious LED replacement program – more than 100,000 fixtures.  Princeton University is implementing many different energy-mitigation projects on campus, and lighting was determined to be a strategy with one of the best overall paybacks. The university’s Energy Group is funding the program, which represents the first significant lighting upgrade at Princeton in more than 20 years.

Case Study: Medical Center Parking Structure

Posted on by

With 7 hospitals and 22 physician locations serving more than 9 Wisconsin counties, ThedaCare has ample room to implement and reap the benefits of building efficiency measures. At the Appleton Medical Center, ThedaCare’s Lighting Energy Efficiency in Parking (LEEP) Campaign Award winning project involved replacing inefficient medium-wattage HID lighting fixtures at a 126,000 square foot parking structure with high efficiency low-wattage LED fixtures. The resulting energy savings exceed 80 percent of the previous usage. A 100-year old company and the third largest health care employer in Wisconsin, ThedaCare has now implemented LED exterior lighting throughout Appleton Medical Center.

Walmart saves over 40% compared to traditional pulse-start metal halides

This report documents the first full parking lot installation of light-emitting diode (LED) products for Walmart, which was done at a Walmart Supercenter in Leavenworth, Kansas. For years, Walmart has explored alternatives to conventional (metal halide [MH] or high-pressure sodium) lighting technologies in its parking lots as a way to save energy, improve the environmental aspects of operation, and potentially reduce maintenance costs. However, the company has approached LED luminaires cautiously pending additional research and analysis.

In 2008, the U.S. Department of Energy (DOE) formed the Retailer Energy Alliance (REA), which brings together similar types of end users to exchange information and leverage buying capacity in order to help expedite market adoption of energy efficient technologies and design practices.1 The REA encompasses several different building system subcommittees (e.g., electrical, mechanical, renewable power). A working group was formed as part of the Lighting & Electrical Subcommittee, of which Walmart is an active participant, to develop an LED parking lot specification. Version 1.2 of the LED parking lot specification was completed in June 2009 and was subsequently expanded to encompass other energy alliances across the broader Commercial Building Energy Alliance (CBEA) (EERE 2011).

With this milestone completed, Walmart agreed to install LEDs across an entire site and in the process “test drive” the CBEA specification
