10 CFR Part 433 Energy Efficiency Standards for the Design and Constuction of New Federal Commercial and Multi-Family High-Rise Residential Builidngs  

This regulation establishes energy conservation performance standards for the design of new commercial, high-rise residential buildings. The standards are designed to achieve the maximum practicable improvements in energy efficiency and increases in the use of non-depletable sources of energy.

These buildings must be designed to achieve energy consumption levels that are at least 30 percent below the levels established by the referenced baseline edition of ANSI/ASHRAE/IES Standard 90.1, which is the national model energy code for commercial buildings. The current federal standard for commercial buildings is based on Standard 90.1-2013, effective January 5th, 2016.
