The Mount Sinai Health System’s new Corporate Services Center at 150 East 42nd Street has received Leadership in Energy and Environmental Design (LEED) Silver Certification from Green Business Certification Inc., a program that recognizes best-in-class building strategies and practices. Certification requires that building projects satisfy prerequisites in areas such as Indoor Environmental Quality, Water Efficiency, and Innovation in Design. “The LEED rating system aims to help owners be environmentally responsible and use resources efficiently,” says Loida Ramos, Vice President, Planning, Design and Construction. “LEED certification means healthier, more productive places, and reduced stress on the environment.”
