Which rating system would be the most appropriate one to use?

A 1,500 ft2 (139 m2) mobile home is built in the downtown area of a major city. 90% of the project’s gross floor will be completed by the time of occupancy. LEED certification is being sought.

Which rating system would be the most appropriate one to use?
A . LEED Interior Design and Construction
B . LEED Building Design and Construction
C . LEED for Homes
D . No rating system

Answer: C

Explanation:

For a mobile home, especially one built in a major city, the most appropriate LEED rating system to use would be LEED for Homes. This is because ASHRAE 90.1 and associated LEED rating systems typically exclude low-rise residential buildings, which include single-family houses, multifamily structures of three stories or fewer above grade, and manufactured houses (modular or mobile homes). Since the mobile home in question falls under the category of manufactured houses, it would be more fitting to pursue LEED for Homes certification, which is designed to cater to residential projects.

Reference: Information derived from the ASHRAE 90.1-2013 User’s Manual indicates the exclusion of low-rise residential buildings, including manufactured houses, from the standard’s scope.
