Final answer:
The ASHRAE standards used for the Energy and Atmosphere category are primarily ASHRAE 90.1 and ASHRAE 189.1.
Step-by-step explanation:
The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) standards used for the Energy and Atmosphere category in building design are primarily the ASHRAE 90.1 and ASHRAE 189.1 standards.
ASHRAE 90.1: This standard provides minimum requirements for energy-efficient design and construction for buildings.
It focuses on reducing energy consumption by setting guidelines for building envelope, HVAC systems, lighting systems, and other energy-related aspects.
ASHRAE 189.1: This standard is specifically for the design of high-performance, sustainable buildings.
It addresses energy efficiency, water efficiency, indoor environmental quality, and other sustainability aspects.
