SE-2426 -- An Evaluation of Energy Conservation Alternatives in an Engineering Office Building ✓ Most Recent

Building 1000 is a 25-year old office building, located at Oak Ridge National Laboratory, Oak Ridge, Tennessee. It is a two-story, wooden frame stru~ture which has been recently covered with aluminum siding. Most of the building's 48,000 ft (4460 m2) of floor area is utilized as offices for approximately 200 engineering personnel. Other characteristics of,the building which were considered in evaluating energy conservation alternatives are as follows:

1. Walls and Floors - Wood, with no insulation
2. Roof - Flat, built-up, with ceiling and 3 in. (7.6 em) of blown wool insulation
3. Windows - Double-hung, with aluminum frames
4. Lights - 2,465 fluorescent bulbf!, 40 watts each
5. Ventilation - 4,700 cfm (133 cmm) exhaust for toilets and blueprint machines
6. Occupancy - 8:00 A.M. to ~:30 P.M., weekdays
7. Heating System - Electric baseboard heaters
8. Cooling System - 160 package air-conditioning units
9. Equipment - Miscellaneous small equipment, such as copiers, vending machines, water coolers, and blueprint machines

Building 1000 bas no characteristics which would make it particularly wasteful or conservative of energy. The building is seen as representative of any number of office buildings, which were built prior to the oil embargo of 1973. Therefore, it provides an opportunity to evaluate energy conservation alternatives which exist in buildings constructed prior to the energyconservation era and which are common throughout the country.
