Which of the following projects is eligible to pursue the Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide?

Which of the following projects is eligible to pursue the Energy and Atmosphere Prerequisite, Minimum Energy Performance, Option 2. Prescriptive Compliance: ASHRAE 50% Advanced Energy Design Guide?
A . 50,000 ft2 (4 645 m2) office project
B . 80,000 ft2 (7 432 m2) hospital project
C . 110,000 ft2 (10 219 m2) school project
D . 140,000 ft2 (13 006 m2) retail project

Answer: C

Explanation:

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.
