The scorecard provides a spreadsheet template for collecting and tracking building data related to energy performance modeling.
This guide discusses how to achieve greater energy efficiency through occupancy behavior analysis and energy auditing to create targeted and strategic behavior change.
This guide explains the benefits and process of building commissioning thereby providing owners and other stakeholders a tool to improve building efficiency and operation. It is intended to be a resource, as well as a call to action, for building owners and facility managers who want to verify their buildings are not only operating as originally intended, but also as efficiently as possible. Commissioning of new construction and major renovations is the primary focus, although commissioning of existing buildings is also briefly discussed as well.
A brief introduction to Operations and Maintenance, the potential energy savings involved, and referral to the O&M Best Practices guide.
This guide provides an overview of the different energy audit options available and information on how to select an energy auditor.
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.
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 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.
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.
