Which standard is utilized as a part of energy benchmarking in LEED?

The choice of ASHRAE 90.1 as the standard utilized for energy benchmarking in LEED is significant due to its comprehensive guidelines that establish minimum energy performance requirements for buildings. ASHRAE 90.1 provides a framework for evaluating the energy efficiency of buildings through various aspects such as HVAC systems, lighting, and renewable energy sources. This standard serves as a critical baseline against which energy performance can be measured and compared.

In the context of LEED certification, adherence to ASHRAE 90.1 is essential as it supports the goal of reducing energy consumption and increasing the sustainability of buildings. It is widely recognized in the industry and utilized as a reference point for establishing best practices in building design and operational performance related to energy use.

The other options, while related to energy or building standards, do not specifically focus on the comprehensive energy benchmarking framework that ASHRAE 90.1 provides. For instance, the ASHRAE 50% Advanced Energy Design Guidelines are aimed more at achieving significant energy savings in specific building types rather than establishing a benchmarking standard. The Electricity American National Standards pertain to electrical standards in general, and Building-Level Energy Metering refers to the actual measurement of energy, which, while important,
