On Jan. 1, the California Green Building Standard Code (Cal Green) became mandatory for all new construction. "Cal Green" is the nation's first mandatory statewide code for "green" construction to fight climate change.
The code aims to reduce greenhouse gases by requiring all new buildings to be more efficient and environmentally responsible. As such, the code has been written to address issues as site design, energy efficiency, water conservation, indoor air quality and recycling. Cal Green will require that every new building constructed in California to:
Reduce water consumption by 20%;
Divert 50% of construction waste from landfills;
Install low emitting pollutant materials;
Install separate water meters for non-residential buildings indoor and outdoor water use;
Provide moisture-sensing irrigation systems for large landscape projects; and
