This document provides an analysis of renewable energy and efficiency options for the Northrop Grumman corporate building located in Falls Church, Virginia. It examines multiple scenarios involving different technology combinations to reduce energy costs and greenhouse gas emissions in line with the company's sustainability goals. Key considerations for the analysis include environmental impacts, technology viability, capital costs and return on investment, electricity pricing, and local regulations. The options considered include energy efficiency upgrades, renewable sources like solar, wind, and fuel cells, backup generators, electric vehicle charging, and integrating solutions with a smart building management system.
