NASA and Constellation Announce a $28 Million Energy Efficiency Project
NASA and Constellation have announced the beginning of a $28.1 million energy-saving project at NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.
This project assists NASA GSFC in meeting its sustainability goals by lowering energy and water consumption across the campus. These improvements are estimated to help NASA GSFC lower its energy consumption by more than 38 million kilowatt-hours per year and eliminate almost 27,000 metric tonnes of carbon emissions.
NASA GSFC is expected to save $1.8 million in annual energy costs and collect $3.3 million in energy efficiency rebates as a result of the numerous campus improvements.
An extensive audit revealed a slew of energy-saving measures, including significant LED lighting upgrades, more efficient HVAC and plumbing replacements, retrofits to laboratory fume hoods, and retro-commissioning of existing buildings - a detailed process of evaluating and analysing the performance of a building's systems to implement measures to ensure the building is operating most efficiently and as designed.
Constellation will also put in place a monitoring-based commissioning (MBCx) system to offer GSFC building managers detailed operational performance indicators in real-time.
For example, if a building is unexpectedly consuming more energy, MBCx will generate a notification when a building parameter falls outside of its specified range and will assist in determining the underlying cause.
Constellation also recently collaborated with Microsoft to create a carbon accounting system that provides clients with a better way to track their clean energy efforts and makes carbon accounting less abstract by linking power use in real-time with a local renewable energy source.
The Giant Company also signed a long-term renewable supply agreement with Constellation to use renewable energy to power its Pennsylvania businesses, which include select stores, gasoline stations, and perishable distribution hubs. This power purchase agreement (PPA) will buy 80 megawatts of renewable energy.
