UN Headquarters in New York City

Marc Karell managed the project including providing a peer review and recommendations for enhancement of the green building and energy efficiency proposals incorporated into the intended billion dollar Capital Master Plan (CMP) renovation of the United Nation’s headquarters campus in New York City. An assessment of building performance against the LEED rating system was undertaken. The project team recommended about 20 design and operational changes to enhance building performance. The UN CMP incorporated nearly all of them into the final design to become a high performing campus complex.
