The building certifications are especially notable as the homes provide affordable housing for “low income” communities.  Both LEED and EGC focus on making the homes energy and water efficient, maintaining good indoor air quality, and look at materials and landscaping used onsite.  The EGC program was specifically designed for low income housing and also addressed common needs and benefits for that population. Some of the EGC requirements include access to open spaces for opportunities to exercise, access to local and fresh food sources, and local job opportunities.  The certification also ensures resilience in case of natural disasters or power outages by requiring access to potable water during an emergency and designing to avoid flooding damage to homes.
