NYC Carbon Challenge for Commercial Offices

NYC Carbon Challenge for Commercial Owners and Tenants

Commercial buildings account for roughly 30 percent of New York City’s emissions and the energy used in leased interior space accounts for between 40 to 60 percent of total energy consumption in a typical commercial office building. However, commercial owners and tenants face a range of barriers to meaningful coordination that delay or prevent uptake of energy efficiency and cost saving measures. These include split incentives, in which the party responsible for making the energy improvement does not reap the costs savings, lack of coordination between base building and supplemental heating and cooling systems, and oversizing of equipment in new tenant space fit-outs.

In 2013, New York City launched the original NYC Carbon Challenge for Commercial Offices to the city’s largest commercial tenants and owner-occupiers. In 2017, to help provide the industry with solutions to coordination barriers, the City launched the NYC Carbon Challenge for Commercial Owners and Tenants—expanding the original Carbon Challenge for Commercial Offices to include additional commercial tenants as well as owners. As part of the expansion, participating commercial owners and tenants will be better equipped to find unique and creative solutions that enable greater energy efficiency and sustainability improvements than either party could achieve on its own.
