Title24 CALGreen: A Guide to California’s Sustainable Building Code
Understanding Title 24 is essential for construction in California, and its green building standards are a critical component. The California Green Building Standards Code, known as CALGreen, forms Part 11 of the Title 24 regulations. It was the nation’s first statewide mandatory green code, created to help achieve the goals of California’s landmark climate law, the Global Warming Solutions Act (AB 32). This legislation identified buildings as a major source of greenhouse gas emissions, prompting the development of sustainable construction standards.
The Legislative Foundation of CALGreen
The legal authority for CALGreen originated from Assembly Bill 32. This law mandated reducing greenhouse gas emissions to 1990 levels by 2020. Subsequently, Senate Bill 1473 specifically empowered the Building Standards Commission (BSC) and other agencies like the Department of Housing and Community Development (HCD) to develop these crucial green building standards for various occupancies.
Evolution from Voluntary to Mandatory
The initial 2008 version of CALGreen contained only voluntary measures. However, the 2010 edition introduced mandatory requirements, ensuring all new California construction projects adhered to sustainable practices. The code was reorganized for better usability, with separate chapters for residential and nonresidential buildings. It established five key divisions: Planning and Design, Energy Efficiency, Water Conservation, Material Efficiency, and Environmental Quality.
Tiered Compliance and User Resources
To encourage higher performance, CALGreen includes voluntary “Tier 1” and “Tier 2” standards. These tiers allow local jurisdictions to adopt more stringent green building measures. To aid with compliance, the state provides comprehensive guidebooks and standardized checklists. These resources help design professionals and building officials effectively apply and enforce the code’s provisions.
Continuous Improvement and Impact
CALGreen is updated triennially, with additions like water recycling mandates and electric vehicle charging infrastructure. Its impact has been significant, contributing to California achieving its greenhouse gas reduction goals ahead of schedule. A state report confirmed emissions fell below 1990 levels, a milestone where CALGreen played an important role.
