A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.

This dynamic document provides background information to any potential audience of building re-tuning training. This document provides background information specifically geared toward small- to medium-sized commercial building operations. It introduces basic building energy terminology associated with building energy use to “prime” targeted participants to get the most out of the building re-tuning training. The intent is for participants who are less familiar with the concepts to review this material before taking the building re-tuning training class.
The primary audience for this instructor manual is the person who will be teaching the re-tuning course. In addition, community college instructors, retro-commissioning training providers and building operator training providers may find value in the material presented in this instructor manual as well. The purpose of this course is to help building operations staff to learn how to operate buildings more efficiently, reduce operating cost and provide energy savings. The knowledge and skills learned through the training will be highly valued by organizations and companies seeking to improve the performance of their buildings. Provides additional information on what to highlight in each of the small building re-tuning slides.

The intent of this user guide is to provide a description of the functionality of the Energy Charting and Metrics plus Building Re-tuning and Measurement and Verification (ECAM+) tool. ECAM+ facilitates the charting and analysis of energy use and point-level data from utility meters, building automation systems (BASs), and data loggers. This document describes the tool’s general functions and features, including installation, use, guidance, and limitations.The Energy Charting and Metrics Tool (ECAM) is an add-on for Microsoft Excel® which was developed to facilitate analysis of data from building (energy and other data). Key features of ECAM+ include the creation of charts to help re-tuning.
One of the nation’s largest schools serving over 60,000 students, the University of Minnesota (U of M) is upgrading the lighting at all 18 parking ramps and garages on its Minneapolis campus. In the Northrop Auditorium Garage, a small 24,000 square foot facility with 75 parking spots, U of M replaced low-wattage high-pressure sodium fixtures with high efficiency, lower- wattage LED fixtures with lighting controls. This Lighting Energy Efficiency in Parking (LEEP) Campaign Award winning project achieved 90% energy savings by upgrading to LEDs with lighting controls.
When it comes to achieving significant sustainability gains, an international retail giant has unique opportunities to cut energy use. With a total of 4,500 sites, Walmart’s commitment to efficiency in parking lighting in new construction and retrofits is paying off in major savings.
As a result of its lighting upgrades Walmart received individual Lighting Energy Efficiency in Parking (LEEP) Campaign awards for a superstore, a neighborhood market and a Sam’s Club. Across 100 stores including both new and retrofitted sites, over 40 million square feet in surfaces for parking and over 100,000 parking spaces, Walmart is saving over 15 million kWh each year as a result of lighting upgrades.
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.
Regency Centers is a national owner, operator, and developer of neighborhood and community shopping centers with over 300 properties throughout the United States. Regency Centers recently upgraded the parking lot lighting at Rona Plaza in Santa Ana, California. Rona Plaza is a grocery-anchored shopping center with 52,000 square-feet of gross lettable area and 250 parking spaces across 77,000 square feet of parking area. Regency Centers retrofitted the existing parking lot and exterior wall mounted fixtures, which were high-intensity discharge (HID) fixtures, with high efficiency LED fixtures coupled with a wireless dimming system. The retrofit resulted in energy savings of nearly 88% compared to pre-existing conditions and was recognized by the Lighting Energy Efficiency in Parking (LEEP) Campaign with the Highest Percentage Energy Savings in a Retrofit at a Single Parking Area award.
This guide primarily applies to facility managers and energy managers of large existing office buildings larger than 100,000 square feet, but also includes considerations for small and medium office buildings. By presenting general project planning guidance as well as financial payback metrics for the most common energy efficiency measures, this guide provides a practical roadmap for effectively planning and implementing performance improvements for existing buildings.
