This guide describes the benefits offered by energy service companies (ESCOs) and the things to consider when selecting and contracting with your provider. The appendix document is also available and contains solicitation and contracting samples.
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".
This report describes miscellaneous electric loads (MELs), the assessment and monitoring of building loads, and how to implement a MEL reduction strategy in lodging facilities.
In order to seize the opportunities for improving energy performance in the United States, it is important to understand what drives American companies and building owners to adopt efficiency improvements and sustainability policies. The research in this report provides new insights on how to create high-performing buildings and how to make the right business case to seize these opportunities.
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.
This report outlines the technical protocol used to generate Department of Energy's Commercial Building Energy Asset Score for commercial buildings, explains the scoring methodology, and provides additional details regarding the Asset Scoring Tool. This report also describes alternative methods that were considered prior to developing the current approach. Finally, this report describes a few features of the program where alternative approaches are still under evaluation.
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 FEDS system allows data input to range from minimal to extremely detailed. With minimal input, FEDS can be used as a top-down, first-pass energy systems analysis and energy resource acquisition decision software model for buildings and facilities. Providing FEDS with more detailed input allows the user to generate optimized building retrofits for an entire installation and provides detailed output for each retrofit in each building set.
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.
