The extension notably increases the square-foot tax deduction for buildings with 50 percent whole-building energy cost savings from $1.80 to $2.25. It also raises from $.60 to $.75 the square foot tax reduction for single systems, such as lighting, HVAC and the building envelope, if savings meet the criteria set forth in the legislation. "Tax incentives like these are crucial because they help building owners make the financial case to implement energy-efficiency upgrades," said Kurt R. Padavano, chairman and chief elected officer, The Building Owners and Managers Association International. Currently, tax incentives allow up to a $1.80-per-square-foot deduction for energy-efficient upgrades that exceed ASHRAE 90.1 (2001) by 50 percent. It also provides up to $0.60 per square foot of partial credit for each of the three subsystems that exceed ASHRAE 90.1 by 16.66 percent. "The opportunity we have to save energy and make our buildings more intelligent and efficient is significant," said Evan Gaddis, president of the National Electrical Manufacturers Association (NEMA). "There is no downside here. It's a win for consumers, building owners, electrical manufacturers and the nation." It is important to remember the bill has merely been introduced, but check back on these pages in the coming months for more updates on the new extension. Until then, electrical contractors can continue to reap the benefits of the EPAct of 2005, which is prompting more facility owners to make the switch to energy-efficient products and systems.

The proposed green building standard is being developed by the three organizations to help drive green building into mainstream building practices and is scheduled for completion in 2007. EPACT 2005 [Source: Building Codes Assistance Project - http://vnvw.bcao-enerav.ora/home.ohol Pa e1of8 IESNA South Pacific Coast Region Energy & Legislative Committee Report June 2007 Incandescent Ban -Latest Developments April 4, 2007 (ROSSLYN, VA) -The members of the Lamp Section of the National Electrical Manufacturers Association (NEMA) today announced a joint industry commitment to support public policies that will transform the U.S. market to more energy-efficient lighting within a decade. There is a growing number of proposals at the international, state and local levels that would eliminate the presence of certain general-service incandescent lamps in the marketplace. Citing this as an issue of national importance, NEMA is calling on the U.S. government to devise a federal solution in order to avoid confusion in the marketplace. Central to this commitment is the setting of standards that will eliminate the least efficient products from the market, based on the following six principles: • The market transformation must be orderly and target as a starting point the least efficient medium screw base A-line incandescent lamps from 40 through 100 watts in widespread use today. • Performance standards must be used to accomplish the transformation. • Performance standards must be technology-neutral. • The market transformation will take up to a decade. • The set of A-line incandescent lamps to be addressed includes clear, frost, soft white and enhanced spectrum. Performance standards will be needed for each of these types. • The market transformation should begin with strategies that will save the most energy. In the absence of a federal solution, states and localities should follow these principles when deliberating on this matter. The member companies in the Lamp Section (listed below) are committed to providing high quality, energy- efficient, and safe lighting products to the public, and they work to ensure that the interests of the lighting consumer and lighting industry are addressed in technical, government, and industry activities in NEMA. The domestic lamp industry represents about $3 billion in lamp shipments covering the commercial, industrial, institutional, residential, automotive, and specialty lighting markets. The member companies are: EYE Lighting International of N.A., Inc. Feit Electric Company, Inc. GE Consumer & Industrial, Lighting Halco Lighting Corporation Light Sources, Inc.

However, these individual comparisons cannot provide an overall effect on code adoption at a state level. Therefore, the whole building cost data derived in the analysis is used for comparisons. The models aze used to derive both difference in cost and difference in energy (power density) between the application of 90.1-1999 and 90.1-2004 LPD levels to each building type. The cost difference is the difference between the whole building lighting cost per squaze foot derived using the 90.1-1999 models and the 90.1-2004 models. The energy difference is the wattage (power density) difference per square foot. These values for the 32 building types are shown in Table 1. Table 1.
