The Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive

Compliance: ASHRAE 50% Advanced Energy Design Guide allows projects to follow the

recommendations of the ASHRAE 50% Advanced Energy Design Guides (AEDGs) for different building

types and climate zones. The AEDGs provide design guidance for buildings that use 50% less energy

than those built to the requirements of the ANSI/ASHRAE/IES Standard 90.1-2004 commercial code1.

However, not all building types and sizes are covered by the AEDGs. According to the LEED Reference

Guide for Building Design and Construction2, the following building types and sizes are eligible for

this option:

Small to Medium Office buildings up to 100,000 ft2 (9 290 m2)

Medium to Large Retail buildings up to 100,000 ft2 (9 290 m2)

K-12 School buildings up to 200,000 ft2 (18 580 m2)

Warehouse and Distribution Center buildings up to 500,000 ft2 (46 450 m2)

Therefore, among the given options, only the school project is eligible to pursue this option, as it falls

within the size limit for the K-12 School AEDG3.
