FALLS CHURCH, Va., Sept. 19, 2011 -- Northrop Grumman Corporation's (NYSE:NOC) green commitment begins at home. The company designed and renovated its new corporate headquarters building to meet the requirements for Leadership in Energy and Environmental Design (LEED) Commercial Interiors Gold level. LEED is an internationally recognized green building certification system.

"The company launched its building renovation with a comprehensive approach to sustainability, from energy efficiencies to mitigate greenhouse gas emissions, to the installation of comprehensive water and waste reduction technologies," said Gloria Flach, corporate vice president and president Enterprise Shared Services, the Northrop Grumman organization responsible for overseeing the renovation project.

Quality American-made, high-efficiency cooling and heating equipment and layers of automated operational controls were incorporated into the design to maximize efficiency and reduce environmental energy use by as much as 30 percent.

Additionally, Northrop Grumman expects the technologically advanced lighting control systems and highly efficient lighting used throughout the building to reduce energy consumption by 15 percent. Other key environmentally-friendly design elements include plumbing fixtures that reduce water consumption by over 35 percent, the use of recycled and locally extracted and manufactured materials, and addressing indoor air quality with low-chemical-emitting paints, sealants, carpeting and adhesives.Â

Under operation, the building is utilizing best management practices for water and waste management to reduce Northrop Grumman's environmental footprint further. From a more sustainable cafeteria to the use of environmentally friendly cleaning supplies, the new headquarters is an accurate reflection of the company's sustainability commitment through its greeNG program.

Developed by the U.S. Green Building Council (USGBC), LEED is intended to provide building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. The hallmark of LEED is that it is an open and transparent process where the technical criteria proposed by USGBC members are publicly reviewed for approval by the almost 20,000 member organizations that currently constitute the USGBC.
