Residential Applications
SLIDE 16
- 1. A building cannot be partially certified. Single units in multi-family buildings cannot
participate in LEED for Homes unless the entire building is registered to participate.
Stacked attached homes, such as condominium flats, are considered to be multi-family buildings.
- 2. Every unit within a multi-family building must earn the same certification level
(e.g. Silver, Gold).
- 3. Separate buildings must be certified separately. Multiple buildings in a complex, or
single-family homes in a subdivision, may be certified separately, but it’s not a requirement that all the buildings or homes be certified or that they meet the same certification level. If multiple buildings are planning to certify through the program, each participating building must be registered with USGBC.
Single-family side-by-side attached homes, such as row houses, are considered to be separate buildings.

SLIDE 37
- LEED-H has more name recognition nationally
- Earthcraft is written for our climate
- Earthcraft may be simpler to apply for an uninitiated team/ owner because it’s more
prescriptive
- Both employ on-site visits, inspections, tests
- Both are less expensive than LEED-NC overall, and Earthcraft-related certification fees
(professional fees plus Earthcraft VA imposed fees) are often lower than LEED-H
- LEED is probably more advanced, though Earthcraft is beyond code in many ways too
- Teams and owners already familiar with LEED would have less of a learning curve moving to
LEED-H vs Earthcraft
- Since the systems have some differing criteria, knowing requirements of each would create a
better building, but only 1 certification is needed, though both can be done.
