Energy Code: About

The New York City Energy Conservation Code (NYCECC) is a series of local laws and the current Energy Conservation Construction Code of New York State (ECCCNYS) that they amend. By State law, all local government energy codes, including the NYCECC, must be more stringent than the ECCCNYS. 

The 2011 NYCECC introduces an entirely new Chapter 1 with New York City administrative and enforcement procedures, amends parts of Chapters 2, 5 and 6 and adds a new Appendix A. 

The NYCECC is comprised of the following:
