NASA AMES OVERVIEWNASA AMES OVERVIEW Located at Moffett Field, CA in the heart of Silicon Valley One of ten (10) NASA field installations with a primary
focus on providing critical R&D on enabling technologies for NASA missions
Approximately 271 structures totaling over 2.6M ft2
Total annual utility spend of $15.5M Aging mechanical and electrical infrastructure
• Three large and inefficient central steam systems• Over sixty chilled water plants• Extensive and problematic pneumatic control systems (minimal
DDC)

UESC UESC PROJECT BACKGROUNDPROJECT BACKGROUND Previously implemented two small
ESPC projects (1999 & 2000) – primarily indoor / outdoor lighting upgrades
Significantly behind federal goals / mandates
Seeking a mechanism to implement a comprehensive & bundled project
Engaged Pacific Gas & Electric (PG&E) in 2010 to discuss the viability of using their UESC program
PG&E/NASA selected AECOM as UESC ESCO partner

FACILITY CHALLENGES / ISSUESFACILITY CHALLENGES / ISSUES Low electric and natural gas rates
($0.045/kWh, $0.70/therm) Significantly behind federal and NASA
energy mandates and goals (224,890 BTU/GSF vs. goal of 157,423 BTU/GSF)
Much of the “low hanging fruit” was included in two prior ESPC projects – eliminated leverage for future projects
Aging and inefficient steam systems causing significant operational issues impacting mission

FACILITY CHALLENGES / ISSUESFACILITY CHALLENGES / ISSUES Many of the facility’s boilers were not in compliance with
local air quality district NOx standards (pending fines) Lacked adequate funding to address boiler NOx
compliance issue within required time frame Funding shortfall for installation of photovoltaic system at
new state of the art headquarters building (required for LEED Platinum certification)

UESC PROJECT GOALS UESC PROJECT GOALS Bundled / integrated project meeting federal
mandates while also addressing critical facility infrastructure needs
Install roof-mounted photovoltaic systems in the new Collaborative Support Facility (Building N232) attain LEED Platinum certification.
Replace aging and inefficient boilers not meeting Bay Area Air Quality Management District standards (approximately 31 boilers)

UESC PROJECT GOALS UESC PROJECT GOALS Replace centralized steam systems with high efficiency
hot water boilers Replace / upgrade existing pneumatic controls with DDC
and integrate to base-wide EMCS Capture utility incentives, rebates, and appropriated
funds to maximize scope of work

PROJECT OUTCOMESPROJECT OUTCOMES Project affected 131 buildings totaling 2.6M ft2
Total construction cost $22M Total financed cost $20.2M over a thirteen (13) year term
Project buy-down included $1.2M of appropriated funds, $420k utility incentives, $300k water incentives (verified by utility)
Additional $600k in retro-commissioning incentives being used to implement additional scopes of work
Annual energy savings: 9,095,382 kWh (9.1% of non-industrial consumption), 957 kW of peak demand, and 1,291,757 therms (33.3% of estimated boiler consumption)
Annual cost savings: $1,648,331 (energy and O&M) Construction will be complete in October 2012
