NASA Jet Propulsion Laboratory – Phase I
In 2011, CEG was awarded a $10.8 million contract from NASA Jet Propulsion Laboratory (JPL) under the U.S. Department of Energy’s Energy Savings Performance Contract. This comprehensive ESPC project involved a wide array of ECMs to drive deeper savings and improve overall building performance for 20 occupied, operationally dependent mission critical facilities. CEG worked closely with building owners, laboratory managers, facilities staff, IT support, CalTech administration, and NASA administration to complete upgrades in mission critical data centers, clean rooms, and laboratories. This project is now saving NASA over 3 million kWh of electricity and 9,000 MMBtu of natural gas annually, resulting in utility savings of over $425,000 per year.
CEG explored a range of energy & water conservation measures to provide a comprehensive solution for NASA JPL. CEG used whole-building analyses to target the most beneficial HVAC upgrades, including building-specific reset schedules and variable flow control upgrades. These upgrades reduced the load of the central utility plants by 30%. Upgrades to the central utility plants included the installation of Turbocor magnetic-bearing chillers, replacement of electric motors and installation of VFDs, installation of a high efficiency condensing boiler, and implementation of temperature reset schedules. Other ECMs included the installation of direct digital controls (DDC), conversion of air handlers to variable air volume (VAV), daylighting control systems, occupancy & timer controls (installation and modification), spectrally enhanced lighting, resizing and reclassifying water utility infrastructure to leverage more favorable rate schedules, and installing time-of-use controls for electric vehicle charging stations.
Because all work was performed in occupied facilities, CEG scheduled the implementation to minimize disruptions to occupants and the various mission-critical projects. Over 10,000 light fixture retrofits and control installations were performed after-hours. Central plant and HVAC upgrades were rapidly implemented over holiday weekends and seasons of reduced load, and work was coordinated to avoid impacting mission schedules. In addition to the directly measurable energy and water cost savings, other benefits of this project included improved lighting levels, reduced maintenance-related work, infrastructure renewal, and more reliable HVAC and central plant operation.
Estimated Savings: $19,500,000
- Annual Savings over $425,000
- Twenty Buildings & Laboratory-wide ECMs
- Electricity Savings of 3.2 million kWh/year
- Natural Gas Savings of 9.3 billion Btu/year
NASA Jet Propulsion Laboratory
NASA JPL is a government-owned, contractor-operated (GOCO) facility that is managed by the California Institute of Technology (Caltech) for the National Aeronautics and Space Administration (NASA). The laboratory’s primary function is the construction and operation of robotic planetary spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA’s Deep Space Network.
