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.
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 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.
