California announces first-in-nation statewide green building standards code

by jbs011910 i3 — January 20, 2010—California Governor Arnold Schwarzenegger announced on January 12 that the California Building Standards Commission unanimously adopted the first-in-the-nation mandatory Green Building Standards Code (CALGREEN) for all new buildings in the state. Taking effect on January 1, 2011, these comprehensive regulations are designed to achieve major reductions in greenhouse gas emissions, energy consumption and water use, and to help California meet its goals of curbing global warming and achieving 33 percent renewable energy by 2020.

CALGREEN will require that every new building constructed in California reduce water consumption by 20 percent, divert 50 percent of construction waste from landfills, and install low pollutant-emitting materials. It also requires separate water meters for nonresidential buildings’ indoor and outdoor water use, with a requirement for moisture-sensing irrigation systems for larger landscape projects and mandatory inspections of energy systems (e.g., heat furnace, air conditioner and mechanical equipment) for nonresidential buildings over 10,000 square feet to ensure that all are working at their maximum capacity and according to their design efficiencies.

Upon passing state building inspection, California’s property owners will have the ability to label their facilities as CALGREEN compliant without using additional costly third-party certification programs, noted the governor. The California Air Resources Board estimates that the mandatory provisions will reduce greenhouse gas emissions (CO2 equivalent) by 3 million metric tons equivalent in 2020.
