What to Consider During the California CHPS Public Review Period

The California CHPS Partner Advisory Committee spent the last quarter updating the CA-CHPS Criteria. This is the first convening of the CA-CHPS Partner Advisory Committee, chaired by Chet Widom, the California State Architect.

In the 2014 Edition of CA-CHPS that is out for public review, only changes to the Core Criteria are considered for public comment. Because the Core Criteria has already been publicly vetted, only those changes, in addition to any missed opportunities, need to be considered for the CA-CHPS update.

General
  • Integrate California Green Building Code (CALGreen) mandatory measures into CA-CHPS Criteria. CALGreen changes that become effective January 1, 2014, apply to new schools, replacement schools, and new buildings on an existing campus (but not modernizations/renovations).
  • New point allocations by category (Table 1, page 9)
Integration
  • The Design for Adaptability, Durability and Disassembly credit has been moved from Material & Waste Management to an Innovation Credit.
  • New Innovation credits are proposed for School Farms and Retro-commissioning.
  • A new credit is proposed for District-wide Sustainability Planning.
Indoor Environmental Quality
  • The minimum filtration is proposed to be increased to MERV 13 from MERV 11 for increased protection given California’s impacted air quality and the greater availability of MERV 13 filters. An additional credit is proposed for MERV 15 or greater.
  • The California-based formaldehyde limit of 9 micrograms per cubic meter is proposed for monitoring if the alternative to flush-out method is used.
  • The Thermal Displacement Ventilation credit is continued from the 2009 Edition of the CA-CHPS Criteria because Title 24 energy modeling rules may not fully account for the energy or indoor air quality benefits.
  • An Electric Vehicle Charging credit is proposed to help improve air quality and reduce global climate change.
Energy
  • The Energy Prerequisite is proposed as 5% better than 2013 Title 24 Energy Standards. 2013 Title 24 compliance is an estimated 7-12% more stringent than ASHRAE 90.1-2010/IECC 2012 which is the Core Criteria national standard. Since the 2014 CA-CHPS Criteria was released for public comment, the effective date of Title 24 has been delayed to July 1, 2014, because the modeling software has not been finalized. In light of this uncertainty, comments are specifically sought on the proper level for the prerequisite.
  • A total of 10 additional points are proposed for the Energy Scale with an emphasis on the first 40% above code.
  • The previous CA criteria for Natural Ventilation and Energy Conservation Interlocks has been merged with the Core Criteria language and further emphasized in recognition that the Title 24 Energy Modeling rules may not fully account for the energy benefits of natural ventilation.
  • A new credit for Low Carbon Schools is proposed
Water
  • Include a credit for a Water Management System
  • Add a new credit for a Demonstration Rainwater Catchment
Site
  • Carry-forward Siting requirements from 2009 CA-CHPS Criteria for public schools in the Siting Prerequisite.
Materials & Waste Management
  • Set the prerequisite for Construction Site Waste Management at 65%.
Operations & Metrics
  • Add a new credit for Active Energy Management for the development and implementation of a behavior-based energy conservation program.
  • Eliminate Power Purchase Agreements (PPA) from qualifying for the Green Power credit.
We encourage all of our stakeholders to participate in the CA-CHPS public review. The first public comment period is open until Thursday, January 9, 2014, 5 PM PST.
December 17, 2013 (Sacramento, CA)With the California CHPS Criteria 2014 Edition under public review, we discuss the major elements that stakeholders should consider when commenting on the public review draft. ~order=2013-12-17
