Commercial Building Energy Asset Score. Program Overview and Technical Protocol (Version 1.0).

摘要

The U.S. Department of Energy (DOE) is developing a voluntary national energy asset score that includes an energy asset scoring tool to help building owners evaluate their buildings with respect to the score. The goal of the energy asset score is to facilitate cost-effective investment in energy efficiency improvements of commercial buildings. The system will allow building owners and managers to compare their building infrastructure against peers and track building upgrade progress over time. The system can also help other building stakeholders (e.g., building operators, tenants, financiers, and appraisers) understand the relative efficiency of different buildings in a way that is independent from their operations and occupancy. DOE's long-term goal is to ensure that there is a linked set of compatible metrics and scoring approaches that building stakeholders can seamlessly use to effectively evaluate a buildings as-built and in-operation efficiencies. DOE envisions these linked scores describing various aspects of building energy performance, such as the performance of building assets, performance of building operations, and how a building compares to its peers. Given this larger vision, the energy asset score is being designed to work in concert with tools such as ENERGY STAR Portfolio Manager. Where possible, the energy asset score incorporates methods that are consistent with ENERGY STAR Portfolio Manager. Prior to beginning the energy asset score effort, DOE performed a market study to ensure that the energy asset score will help address market needs and fill identified gaps. In 2012, DOE began initial pilot testing of the energy asset score. As a result of that effort, improvements to the tool, training materials, and other aspects of the program have been made. In 2013, DOE will continue to assess the energy asset score through additional pilot testing as well as evaluations and analyses. Results from these efforts will be published in a separate document.
