USGBC released the complete suite of LEED v4.1 rating systems in April. They include:
- Building Design and Construction (BD+C)
- Interior Design and Construction (ID+C)
- Operations and Maintenance (O+M)
- Residential
- Cities and Communities and Recertification
A few significant updates to the BD+C category are the inclusion of both cost and greenhouse gas emissions to energy metrics as well as a new renewable energy credit. For the O+M category, which is for existing buildings, the council has shifted to data-based documentation by tracking performance in energy, water, waste, transportation, indoor air quality, toxin-free environment and occupant satisfaction.
