[Code of Federal Regulations] [Title 41, Volume 2] [Revised as of July 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 41CFR101-20.107] [Page 207-208] TITLE 41--PUBLIC CONTRACTS AND PROPERTY MANAGEMENT CHAPTER 101--FEDERAL PROPERTY MANAGEMENT REGULATIONS PART 101-20--MANAGEMENT OF BUILDINGS AND GROUNDS--Table of Contents Subpart 101-20.1--Building Operations, Maintenance, Protection, and Alterations Sec. 101-20.107 Energy conservation. Agencies shall comply with the energy conservation guidelines set forth in 10 CFR part 436 (Federal Energy Management and Planning Programs) and shall observe the energy conservation policies cited herein. (a) Agencies shall ensure that lights and equipment are turned off when not needed, that ventilation is not blocked or impeded, and that windows and other building accesses are closed during the heating and cooling seasons. (b) Except where special circumstances exist, illumination levels shall be maintained as near as is practical to the following standards: (1) 50 foot-candles at work station surfaces, measured at a height of 30 inches above floor level, during working hours (For visually difficult or critical tasks, additional lighting may be authorized by the GSA buildings manager or by agencies that have been given delegated authority to perform buildings management functions.); (2) 30 foot-candles in work areas during working hours, measured at 30 inches above floor level; (3) 10 foot-candles, but not less than 1 foot-candle nonwork areas, sufficient to ensure safety in non-work areas during working hours. (Normally this will require levels of 5 foot-candles at elevator boarding areas, minimum of 1 foot-candle at the middle of corridors and stairwells as measured at the walking surface, and 1 foot-candle at the middle of corridors and stairwells as measured at the walking surface, and 10 foot-candles in storage areas.); and (4) Other lighting essential for safety and security purposes, including exit signs and exterior lights, shall be maintained. (c) Within the limitations of the building systems, heating and cooling systems shall be operated in the most overall energy efficient and economical manner. (1) Temperatures will be maintained to maximize customer satisfaction by conforming to local commercial equivalent temperature levels and operating practices. GSA will seek to minimize energy use while operating its buildings in this manner. During non-working hours, heating temperatures shall be set no higher than 55 degrees Fahrenheit and air-conditioning will not be provided except as necessary to return space temperatures to a suitable level for the beginning of working hours. (2) The locations used for measurement of temperatures to determine compliance will be representative of the spaces to be heated or cooled. (3) Work stations which are the most adversely affected may be the basis for establishing the temperature levels throughout that portion of the building. (4) Reheating, humidification, and simultaneous heating and cooling shall not be permitted. (5) During extreme weather conditions, building systems shall be operated as necessary to protect the physical condition of the building. (d) The operation of portable heaters, fans, and other such devices in Government-controlled space is prohibited unless authorized by the GSA buildings manager or by agencies that have been given delegated authority to perform buildings management functions. (e) During working hours in periods of heating and cooling, provide ventilation in accordance with ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality where physically practical. Where not physically practical, provide the maximum allowable amount of ventilation during periods of heating and cooling and pursue opportunities to increase ventilation up to current standards. ASHRAE Standard 62 is available from ASHRAE Publications Sales, 1791 Tullie Circle NE, Atlanta, GA 30329-2305. (f) Energy standards for existing buildings will be no less stringent than those prescribed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers and the Illuminating Engineering Society of North American in ASHRAE/IES Standard 90A-1980 as amended by Department of Energy (DOE). These energy standards are applicable where they can be achieved through life cycle, cost effective actions. [[Page 208]] (g) Exceptions to the foregoing policies may be necessary for specialized requirements of for agencies to accomplish their missions more effectively and efficently. Such exceptions may be granted by the GSA buildings manager or by agencies that have been given delegated authority to perform buildings management functions. (h) Contracting officers shall ensure that all new lease contracts are in conformance with the policies prescribed in this Sec. 101-20.107. Existing lease contracts shall be administered in accordance with these policies to the maximum extent feasible. (i) Each agency shall report to the Department of Energy (DOE) the energy consumption in buildings, facilities, vehicles, and equipment under its control within 45 calendar days after the end of each quarter as specified in the DOE Federal Energy usage Report DOE F 6200.2 instructions. This report has been cleared in accordance with FPMR 101- 11.11,\1\ Interagency Reports Management Program, and assigned interagency report control number 1492 DOE OU. --------------------------------------------------------------------------- \1\ Editorial Note: At 50 FR 26908, June 28, 1985, 41 CFR part 101- 11 was recodified as 41 CFR parts 201-22 and 201-45.
