Green Features of the Astellas Headquarters for the Americas
Northbrook, Ill., Facility Achieves LEED Gold Certification
Our headquarters for the Americas in Northbrook, Ill., achieved LEED Gold certification by the U.S.
Green Building Council (USGBC). LEED, which stands for Leadership in Energy and Environmental Design,
is one of the primary rating systems for the design, construction and operation of energy-efficient
buildings. A Gold certification indicates that the buildings are designed and constructed with
sustainable concepts and practices that substantially reduce their impact on the environment as
compared to other, similar facilities.
"This honor further demonstrates our commitment to the environment, the local community, and as an
employer of choice to our employees," said Collette Taylor, Astellas, Senior Vice President Human
Resources & Corporate Administration of Astellas and headquarters project manager. "With energy
costs and carbon emissions on the rise, we're thrilled that we invested in green building at our
The Northbrook complex obtained LEED Gold certification for its environmentally conscious
- Use of a hybrid geothermal field, which uses the earth as a heat source in the winter or heat sink in the summer to reduce energy costs by more than 20 percent
- More than 77 percent of wood was grown in managed forests certified by the Forest Stewardship Council
- Use of 35 percent recycled materials and 45 percent locally manufactured materials, plus the recycling of more than 85 percent of waste during construction
- Improved indoor air quality, with building flush-out using outdoor air to remove the majority of pollutant emissions
- Providing outdoor air more than 30 percent above the mandated standard
- Use of high-efficiency heating and air-conditioning equipment and plumbing fixtures to reduce water consumption
- Indoor secured bicycle storage and showering facilities
- More than 70 percent of the facility's parking under cover to reduce heat island
- Landscape irrigation from retained storm water
Tapping Into Earth's Energy
One "cool" feature of the headquarters for the Americas is the hybrid heating and cooling system using both traditional and geothermal technology. The hybrid geothermal field, which works by using the more stable temperatures found deep in the earth and pumping water into deep wells that access these areas, acts as a heat source in the winter and a heat sink in the summer. This geothermal technology allows Astellas to save more than 25 percent of the energy cost associated with a traditional heating and cooling system while reducing our carbon footprint. The energy savings, with the help of a government energy savings credit, helps offset the construction premium and is expected to pay for itself in less than four years.
Opened in June 2012, the complex includes two six-story buildings totaling 425,000 square feet, with ample space to build a future third building to accommodate the company's projected growth.
