To meet requirements under the LEED Energy and Atmosphere category, the project team needs to...

Per the LEED v4 BD+C Reference Guide, the baseline for energy performance evaluation is based on:

"ANSI/ASHRAE/IESNA Standard 90.1-2010" for most projects under EA Prerequisite: Minimum Energy Performance and EA Credit: Optimize Energy Performance.

This standard sets the minimum energy efficiency requirements for buildings (excluding low-rise residential) and is the benchmark against which a project's proposed design is compared when using the energy simulation modeling method (whole building energy simulation).

ASHRAE 90.1-2010 defines criteria for HVAC systems, building envelope, service water heating, power, lighting, and other systems affecting energy use.

LEED requires performance above this baseline to earn points.

The other options are not appropriate baselines:

A. SMACNA: Refers to HVAC ductwork and air quality guidelines, not energy baseline standards.

B. ENERGY STAR®: Is a benchmarking tool, not a baseline standard used in energy modeling.

D. ASHRAE 62: Covers ventilation and indoor air quality, not energy performance.

Therefore, the correct baseline standard is ASHRAE 90.1-2010.
