Douglas Mass


Doug is the President of Cosentini, internationally recognized in the design and construction industry because of his expertise as a mechanical engineer, his commitment to design innovation, and a long list of high-performance building projects designed by leading architects. His work in the area of LEED/sustainable design has involved design commissions from both corporate and government clients who have sought his assistance on the development of building systems that are energy efficient, ensure occupant comfort, and promote the preservation of the environment. Under his direction, Cosentini has engineered more than 50 projects that have received LEED certification, and more than 100 current projects that will achieve various levels of LEED certification.

Doug’s career spans more than 30 years and includes pioneering achievements such as the design of the first sustainable high-rise office building in Manhattan (4 Times Square) and the first LEED Gold residential high-rise in the country (The Solaire in New York City’s Battery Park City). He is also well-known for implementing underfloor air delivery systems at the first corporate headquarters in the US to incorporate this technology (Owens-Corning’s headquarters in Toledo, OH), as well as subsequent advances as seen in Goldman Sachs’ new headquarters in New York City and FedEx’s new headquarters in Memphis, TN. A significant current project is Shanghai Tower, which at 638 meters will be the tallest building in China.

Mr. Mass’s dedication to the education of future engineers and architects is evident in his service at Columbia University’s School of Architecture and at his alma mater, Brown University. He is also a committed lecturer who has spoken extensively on sustainable design and underfloor air system design at the US Department of State, the New York City Economic Development Corporation, and ASHRAE. He has a Bachelor of Science in Mechanical Engineering from Brown University, is a registered engineer in 26 states and two Canadian provinces, and is a member of the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE), the U.S. Green Building Council (USGBC), and serves on the board of the Salvadori Center.
