Building Energy Standards Program: Determination Regarding Energy Efficiency Improvements in the Energy Standard for Buildings, Except Low-Rise Residential Buildings, ANSI/ASHRAE/IESNA Standard 90.1-2004
The Department of Energy (DOE) today determines that the 2004 edition of the Energy Standard for Buildings, Except Low-Rise Residential Buildings, American National Standards Institute (ANSI)/ American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Illuminating Engineering Society of North America (IESNA) Standard 90.1-2004, (Standard 90.1-2004) would achieve greater energy efficiency in buildings subject to the code, than the 1999 edition (Standard 90.1-1999 or the 1999 edition). The quantitative analysis of the energy consumption of buildings built to Standard 90.1- 2004, as compared with buildings built to Standard 90.1-1999, indicates national source energy savings of approximately 13.9 percent of commercial building energy consumption. Site energy savings are estimated to be approximately 11.9 percent. As a result of this positive determination regarding Standard 90.1-2004, each State is required to certify that it has reviewed the provisions of its commercial building code regarding energy efficiency, and updated, as necessary, its code to meet or exceed Standard 90.1-2004. This Notice provides guidance to States on Certifications, and Requests for Extensions of Deadlines for Certification Statements.
Request for Information for Photovoltaic Community Project: Fielded Photovoltaic Systems and Components Data
The Department of Energy (DOE) today gives notice of a Request for Information (RFI) to invite comment on approaches to address the need for consistently-collected reliability data of fielded photovoltaic systems, data analysis to deduce methods for assessing reliability and to improve accelerated aging tests to create predictive models, improvement in existing tests, more information on best practices for reliability and accelerated aging tests, and assessing the nature and frequency of safety-related issues (arcing, building integration aspects, and ground faults) and their relationship with long-term performance. It is clear that the foundation to address these needs is a database consisting of photovoltaic system and component reliability, as well as performance data, which are collected in a consistent manner. In addition to the database, it is necessary for DOE to collaborate with the national laboratories and others to evaluate the data, develop new or modified tests, assess safety, evaluate system and component interactions, and develop predictive models. DOE is issuing this RFI for information and feedback from the PV community stakeholders. These include, but are not limited to, system operators and integrators, utilities, project planners, financial planners, manufacturers, third-party data-aggregation companies, universities, testing facilities, and other interested parties. See the SUPPLEMENTARY INFORMATION section of this document, which provides further detail and comments requested.
