CALGreen Overview and Resources

23 Aug

CALGreen 2010Whether you agree with it or not California’s new green building code (CALGreen) is looming on the horizon (going into effect January 1, 2011) and developers, architects, planners, engineers, plan checkers, inspectors, building officials and others involved in designing and approving new construction are scrambling to wrap their arms around the new code and what it means to each tier in the development process. This is the nation’s first mandatory state-wide green building code, intended to encourage more sustainable and environmentally friendly building practices, require low pollution emitting substances that can cause harm to the environment, conservation of our natural resources, and promote the use of energy efficient materials and equipment.

The Five CALGreen Code Categories:

  1. Planning and Design
  2. Energy Efficiency
  3. Water Efficiency and Conservation
  4. Material Conservation and Resource Efficiency
  5. Environmental Quality

CALGreen Requirements for New Buildings:

  • Reduce water consumption by 20 percent.
  • Divert 50 percent of construction waste from landfills.
  • Install low pollutant-emitting materials.
  • Requires separate water meters for nonresidential buildings’ indoor and outdoor water use.
  • Requires moisture-sensing irrigation systems for larger landscape projects.
  • Requires 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.

CAlGreen Facts:

  • The Code is a comprehensive and uniform regulatory code for all residential, commercial, hospital and school buildings.
  • CALGreen will allow cities to impose more stringent standards or provide additional sustainability incentives.
  • It has both mandatory components as well as voluntary components that can be adopted by local jurisdictions (Tier 1 and Tier2).
  • Mandatory measures include elements currently regulated by other agencies (i.e. stormwater pollution prevention (SWPPP), energy efficiency).
  • California Air Resources Board estimates that the mandatory provisions will reduce greenhouse gas emissions (CO2 equivalent) by 3 million metric tons in 2020.
  • The CALGreen Code will not require businesses or property owners to pay additional fees for certification.

CALGreen Bottom Line

CALGreen isn’t going to make a huge difference in building practices in California, most of the requirements are relatively inexpensive.  Where extra costs may have an effect is in pulling a building permit, the entire building documentation and inspection process will change significantly under the new code and many of the inspections required by CALGreen do not currently exist and will require training and education, an expense most cities cannot afford now days.  This may have a huge effect on the residential side of the code.  Also, CALGreen represents the beginning of incremental changes to California’s building standards which will continue to become more stringent in the future.  The new requirements will also lead to an increase in the retrofit market with owner’s and developers focusing on existing buildings rather than building new ones, a market that is under served in California at the present moment.

Following is  a list of relevant resources regarding CALGreen.  I will be periodically writing about the code and adding more resources as well as upcoming events and presentation about the code as well as how it relates to existing voluntary green building standards such as LEED and Build it Green.

CALGreen and Its Impact on Third Party Certification Programs – Build It Green notes “…there is still much work needed to refine and implement the code [CALGreen] including measure definition, education to affected parties and clear strategies to reconcile and understand how the code relates to the growing number of municipal green building ordinances based on established third-party verified green building programs.”
