Draft Commercial Replacement & Attachment Window Solutions Advancement Plan

This draft Advancement Plan summarizes available information for a proposed Market Transformation Initiative (MTI), called Commercial Replacement & Attachment Window Solutions. It describes the scope of work for research, testing, and stakeholder engagement that would be needed to develop a full MTI Plan for approval by the CPUC for implementation.

This proposed MTI would offer a significant opportunity to improve building envelope thermal performance and downsize heating, ventilation, and air conditioning (HVAC) systems. It would seek to address the many commercial buildings that still contain single pane glass windows and offer substantial improvements over typical window replacements.
