These appendices contain solicitation and contract samples for working with energy service contractors (ESCOs) and go with the previously published, "A Guide to Performance Contracting with ESCOs".
Pacific Northwest National Laboratory (PNNL) with funding from the U.S. Department of Energy's Building Technologies Program (BTP) evaluated a number of control strategies that can be implemented in a controller, to improve the operational efficiency of the packaged air conditioning units. The two primary objectives of this research project are: 1) determine the magnitude of energy savings achievable by retrofitting existing packaged air conditioning units with advanced control strategies not ordinarily used for packaged units and 2) estimating what the installed cost of a replacement control with the desired features should be in various regions of the U.S. This document reports results of the study.
The purpose of this report was to analyze the potential market value of a commercial building energy asset rating program for the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy. It Identifies core messaging to motivate owners, investors, financiers, and others in the real estate sector to adopt a voluntary asset rating program and, as a consequence, deploy high-performance strategies and technologies across new and existing buildings.
While tungsten-halogen (halogen) lamps have traditionally been used to light surgical tasks in hospitals, LED technology offers the potential for adjustable color and improved color rendition/quality, while reducing side effects from non-visible radiant energy. LED lighting also offers significant energy savings. This document was developed as part of a Hospital Energy Alliance (HEA) Lighting Project Team initiative.
This fact sheet was developed to provide objective guidance to hospital owners and managers seeking to acquire high-performance LED surgical task lights. It discusses potential advantages for using LEDs, industry standard performance metrics, color characteristics, lifetime characteristics, recommended specifications structure, and performance verification.
The Walmart Supercenter in Leavenworth, Kansas, offered a test case to determine whether an LED system could meet the CBEA specification and be competitive with conventional systems when maintenance and energy costs were factored in. The LED system was compared to two systems: a 1,000-watt (W) pulse-start metal halide (PMH) and a 400-W PMH. This case study provides initial results and results after two years.
This document provides a framework for standard measurement and verification (M&V) of lighting retrofit and replacement projects. It was developed to provide site owners, contractors, and other involved organizations with the essential elements of a robust M&V plan for lighting projects. It includes details on all aspects of effectively measuring light levels of existing and post-retrofit projects, conducting power measurement, and developing cost-effectiveness analysis. This framework M&V plan also enables consistent comparison among similar lighting projects, and may be used to develop M&V plans for non-lighting-technology retrofits and new installations.
This document, developed in response to the hospitality sector’s increasing interest in using HVAC occupancy-based control (OBC) systems to reduce the energy used by unoccupied guest rooms, provides information on a technology demonstration evaluating the energy-savings potential of OBC systems produced by five manufacturers. These systems were deployed in six different hotels in three metropolitan areas and the report documents the research team’s calculation of aggregate and location-specific energy savings across four study periods, from December, 2011 to August, 2012.
This case study details Cleveland Clinic’s conversion to LED lighting in its six-story, 3,000-space 100th Street parking garage, using the Commercial Building Energy Alliances (CBEA) High-Efficiency Parking Structure Lighting specification. Cleveland Clinic used the specification to prepare its request for proposals, which was sent to six manufacturers, with five submitting bids. The case study details the criteria used to evaluate the bids and illustrates a comparison between the existing 200-watt high-pressure sodium (HPS) system and the LED replacement system.
