building

The Lyman Spitzer Building (LSB) is located at the Princeton Plasma Physics Laboratory (PPPL), which is funded by the Department of Energy (DOE) and managed by PrincetonUniversity. The LSB is the Laboratory's main administration building, providing office space, workshops, meeting facilities, and computing support for more than half of PPPL's employees. The building also provides the main control room for operating PPPL's major fusion energy experiment, the National Spherical Torus Experiment (NSTX).

 

In 2007, PPPL began using ENERGY STAR tools and Portfolio Manager to benchmark the energy performance of LSB. After determining the baseline energy performance of the building, PPPL began tracking its energy performance on a monthly basis. In 2008, the organization became an ENERGY STAR partner, solidifying its commitment to the ENERGY STAR program.

 PPPL has placed major emphasis on improving its energy performance, including that of the LSB. A complete lighting retrofit project was completed to replace T12 bulbs with 32-watt T8 bulbs, which reduced overall lighting load by 20 percent. In addition, approximately 200 ceiling incandescent reflective floodlight bulbs were replaced with reflective floodlight compact fluorescent lamps (CFLs), which resulted in an 80 percent reduction in wattage while also significantly reducing lighting maintenance. A building automation system is used to turn off lighting and adjust building temperatures to reduce energy load during off hours.

 In addition to lighting energy reductions, the HVAC and water cooling systems were modified to improve overall efficiency. Direct-digitally controlled (DDC) controlled variable frequency drive fans and enthalpy economizer DDC programming were installed, which not only provided for increased energy efficiency but also improved indoor air quality and worker comfort. In 2008, PPPL replaced six 3-way pneumatically-controlled chilled water control valves with 2-way direct digital control modulating control valves. PPPL estimates that the valve replacement project will save as much as 475,000 kWh annually.

 A small computer center housed in the basement of the building has been dismantled as of January 2014.
