Commercial Replacement & Attachment Window Solutions MTI Plan

May 12, 2026

This MTI Plan is open for public comment on the CPUC Public Documents Area through Tuesday, June 9.

CalMTA’s Commercial Replacement and Attachment Window Solutions (CRAWS) market transformation initiative (MTI) seeks to reduce carbon intensity of buildings through improved building envelope thermal performance and downsized heating, ventilation, and air conditioning (HVAC) systems.

This Market Transformation Initiative (MTI) Plan describes the business case for investment in the MTI including strategic interventions, intended market outcomes, and evaluation activities that will be implemented during Phase III: Market Deployment. This investment would result in long-term energy efficiency and other benefits for California. The MTI Plan was developed using the findings of Phase II assessment and research, which are detailed in the appendices of this document. 

The Commercial Replacement and Attachment Window Solutions (CRAWS) Market Transformation Initiative (MTI) offers a significant opportunity to reduce carbon intensity of buildings through improved building envelope thermal performance and downsized heating, ventilation, and air conditioning (HVAC) systems.

This draft MTI Plan is based on more than two years of development, research, outreach, and analysis. Links to the supporting appendices are listed to the right. CalMTA will submit this the full plan and appendices to the California Public Utilities Commission (CPUC) via an Application in 2026 following MTAB review and public comment.
