ASHRAE Manual for Saving Energy
(Oct.3) An updated version of the User’s Manual for ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, is now available. The manual is intended to assist users of the ASHRAE/IESNA energy-conservation standard in energy-efficient design. It has gone through an extensive revision process to incorporate the various addenda approved since the 2004 edition.
Updates have been made to reflect and illustrate the changes in every portion of the 90.1 Standard. Changes have been to Appendix G, which provides specific guidance on the rules and procedures used to simulate building energy and energy costs, when the objective is to substantially exceed the requirements of 90.1.
“The Appendix G changes will be particularly useful to people involved with projects that are trying to achieve a certain amount of savings over and above the minimum requirements of the standard,” said Keith Emerson who oversaw review of the manual for the Standard 90.1 committee.
The 90.1-2007 User’s Manual illuminates the standard by providing detailed instruction, calculation examples and compliance forms for the design of commercial and high-rise residential buildings. It includes sections on administration and enforcement, building envelope, HVAC systems, service water heating, power, lighting, the energy-cost budget method and the building-performance rating method.
California to Mandate Energy-Use Reporting
(Sept. 29) A law requiring annual energy-use reporting for all California’s nonresidential buildings takes effect in January 2009, and the state Department of General Services has been working closely with utilities to streamline the reporting process, according to www.BuildingGreen.com. Beginning in 2010, owners of commercial buildings must disclose their energy usage and ENERGY STAR rating to potential buyers, leasers, and financiers. The legislation, which is similar to a European Union (EU) requirement that took effect in 2006–2007, was signed into law in October 2007.
The California regulation differs from the EU law because it looks only at actual energy use, while the EU also requires a computer-modeling estimate of projected use based on the efficiency of the building’s systems, which gives potential buyers more data to work with. Researchers at the Lawrence Berkeley National Laboratory and elsewhere are exploring the potential of a more robust benchmarking system that would provide guidance on energy use by specific systems within the building, which would help identify conservation opportunities.
Kohl’s Opens 45 Stores Built to LEED Standards
Menomonee Falls, Wis. Kohl’s Corp. on Wednesday celebrated the opening of 47 stores, giving it a total of 1,000 locations nationwide. Of the 47 new stores, 45 are built according to LEED (Leadership in Energy and Environmental Design) standards. The stores are pre-certified at the silver level from the U.S. Green Building Council.
Among the stores opening are Kohl’s first locations in the Miami-Fort Lauderdale-West Palm Beach area, as well as the first store in Montana, which marks the company’s 48th state. In total, the retailer will open 75 stores in 2008, giving it 1,004 stores in 48 states by the end of November. In 2009, Kohl’s plans to open approximately 50 new stores and remodel 60 locations, an increase from 36 remodeled stores in 2008.
