Purpos
2、e. This ETL establishes energy performance standards for replacing, upgrading, or modifying equipment. These standards are designed to achieve the maximum practicable improvements in energy efficiency, cost effectiveness, and water conservation. 2. Application. Requirements of this ETL are mandatory
3、 for all facilities equipment on Air Force installations. 2.1. Authority. This ETL incorporates the new requirements of the 1994 edition of 1 O CFR 435 and the Energy Policy Act of 1992 (Public Law 102-486). 2.2. Effective Date: Immediately. Expires five years from date of issue. 3. Reference Public
4、ations. 3.1. 1 O CFR 435, Energy Conservation Performance Standards for New Buildings, 1 January 1994 (refer to Attachments 3 through 6, this ETL). 3.2. ETL 94-5, Fire Protection Engineering Criteria and Technical Guidance - Emergency Lighting and Marking of Exits. 4. Specific Requirements. Replace,
5、 upgrade, or modify equipment in accordance with the following minimum requirements, as specified in 1 O CFR 435. 4.1. Lighting. 4.1.1. Work Areas. For work areas larger than 450 ft2, check lighting levels and set IAW Attachment 3, page 1. At least one lighting control must be used for each task or
6、group of tasks within each 450 ft2. 4.1.2. Individual Fluorescent Fixtures.

Do not use incandescent lighting for replacements. Use LED lights ONLY. 4.1.4. Exterior Lighting. Exterior lights must have
10、photoelectric cells or attached timing devices. Refer to Attachment 3, sheet 3, for required lighting levels. 4.1.5. Fluorescent Lamp Ballasts. Fluorescent lamp ballasts must have a ballast efficacy factor not less than specified in Attachment 3, sheet 2. The power factor for these ballasts must be
11、equal to or greater than 90 percent. 4.2. Motors. Motors will meet minimum efficiency standards IAW Attachment 4. Do not rewind motors except under emergency conditions. Replacement motors should achieve the highest efficiency and lowest energy consumption when meeting facility load requirements. Ev
12、aluate using motors with variable speed drives as replacements whenever possible. NOTE: Recommend using Motor Mastep computer software for a listing of manufacturers of motors suitable for normal operations. Motor Mastep is included in the Construction Criteria Base (CCB). 4.3. HVAC Systems. Validat
