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.

The second largest gaming company in the world by revenue, MGM Resorts International (MGM) has recently installed energy efficient parking area lighting and controls at 65% of its U.S. facilities. With 20 U.S. facilities in NV, MI, and MS, MGM lighting projects have covered more than 8 million square feet of parking area. By replacing more than 4,400 existing metal halide and high-pressure sodium light fixtures in the parking facilities with a mixture of LED and induction fixtures, MGM saved 4.5 million kWh per year across their portfolio.
Most impressively, at the MGM Grand Detroit Casino–a 401-room hotel and gaming facility— the company achieved 4 million kWh of annual energy savings by replacing medium-wattage metal halide fixtures in a 2.6 million square foot parking structure with high efficiency, low- wattage LED fixtures.
The JBG Companies (JBG), an investor, owner, developer, and manager of real estate in the Washington, D.C. Metropolitan Area, achieved almost 50% energy savings compared to energy code by using a combination of high efficiency LEDs coupled with lighting controls for the parking structure at the National Cancer Institute (NCI) Shady Grove in Maryland. The NCI
parking structure was recognized by the Lighting Energy Efficiency in Parking (LEEP) Campaign for the Highest Percentage Energy Savings in a Single Parking Structure (New Construction)
and Highest Absolute Annual Energy Savings in a Single Parking Structure (New Construction). In addition to its 2014 LEEP Campaign Award, the buildings have also been recognized in 2011, 2013, and 2014 by both local Maryland organizations and national organizations.
The Howard Hughes Corporation upgraded the lighting for the parking structure at the Ward Centers in Honolulu, Hawaii. Currently, the Ward Centers is occupied by 130 national retailers, local shops and restaurants in five shopping districts. The Ward Centers parking structure is seven stories high, and encompasses nearly 300,000 square feet and houses over 800 parking spaces.
The parking structure is a 2014 Lighting Energy Efficiency in Parking (LEEP) Campaign Award winner for Best Use of Lighting Controls in a Single Facility as the new lighting system uses both LED and fluorescent fixtures along with various lighting controls. The Ward Centers was able to achieve 75% in energy savings.
With more than 40,000 parking spaces to light Cox Enterprises, owner of Manheim Pennsylvania Auto Auction, the world’s largest auto auction carries a sizable electric load. The lot achieved 50% outdoor lighting energy savings through a retrofit of outdoor lighting—totaling 1.8 million kWh in annual savings over the 13.5 million square foot facility.
Cox’s Lighting in Energy Efficiency in Parking (LEEP) Campaign Award winning project retrofitted high-wattage metal halide fixtures with reduced- wattage pulse-start metal halide lamps and a wireless control system. The controls enable further energy savings by allowing fixtures to be turned off when not needed. In addition to the energy savings, the longer rated life of the new lamps also reduces maintenance costs. The significant energy saving from the new fixtures and lighting controls resulted in a simple payback period of less than 4 years.
This document provides an example request for proposal (RFP) for a Department of Energy (DOE) and National Renewable Energy Laboratory (NREL) Ingress/Egress Project with a Site Entrance Building and Parking Structure. The RFP has been annotated by NREL to demonstrate the project’s steps that follow NREL and DOE’s Energy-Performance-Based Acquisition process.
This guide was created to help healthcare facility decision-makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
This paper illustrates the challenges of integrating rigorous daylight and electric lighting simulation data with whole-building energy models, and defends the need for such integration in order to achieve aggressive energy savings in building designs. Through a case study example, we examine the ways daylighting – and daylighting simulation – drove the design of a large net-zero energy project.
The California Energy Commission’s Public Interest Energy Research (PIER) program sponsored development of bi-level parking garage luminaires for the University of California, Davis that integrate intelligent controls with bi-level electronic drivers or ballasts to control light output based on garage occupancy. Luminaires operate at a reduced level during vacancy and switch to full light output upon occupancy. Many of the products may be combined with traditional photocontrols to maximize energy savings.
Adaptive exterior lighting is a relatively new concept recognized by the lighting industry and energy regulators as a potential method to increase energy savings in outdoor applications. Many adaptive exterior lighting products are being developed and have been introduced into the marketplace, allowing users to implement dynamic lighting designs that offer 30%–75% energy savings over traditional systems. These savings are achieved by coupling advanced lighting controls with an efficacious, dimmable source.
