While mature, many commissioning strategies have not reached wide market adoption. While commissioning required building code has helped, it is only required for nonresidential buildings over 10,000 square feet, with limited mechanisms to ensure performance will persist over time. ET investments should focus on supporting wider market adoption of commissioning and technologies to ensure performance is maintained over time.

System modeling and analytics solutions are advancing rapidly with growth of sensors and IoT devices, data availability, and software capabilities. Additionally, traditional first-principal energy modeling is time consuming and, in many cases, cost prohibitive. ET investments should focus on demonstrating use cases that reduce cost and timelines: measuring energy and GHG savings, approaches for using analytics in utility programs, and first-principal energy modeling.

BPS and NMEC program solutions are being deployed, but there is a lack of understanding of the technical and market barriers, as well as limited tools and technologies for meeting targets or maximizing incentives. ET investments should focus on technologies that help buildings achieve BPS targets or improve NMEC incentives.

REA systems face several challenges including cost of smart panels, complexity for residential occupants, uncertainty and dynamics of loads and generation, optimal capacity configuration, control strategies, infrastructure limitations, and microgrid challenges. ET investments should focus on lower cost solutions, proof of usability for residential occupants, pilot adoption scenarios, and demonstrating use cases,

Potential barriers studies should address:

• Barriers to NMEC: There is a need for validation of automated NMEC software and calculation algorithms, including handling of nonroutine events. Market studies should address technology and service providers and technology and market barriers. Measure development and program opportunities include streamlined custom measure verification process and tools to increase program participation for NMEC projects. Measure development should align with California Technical Forum (Cal TF) Custom Measure efforts.

• Barriers to Residential Energy Automation Systems: There is a need for a detailed breakdown of benefits by feature combined with comparative analysis among products. Market studies should address a comprehensive analysis including a market survey, literature review, and energy modeling to quantify benefits by climate zone and system type. Measure development and program opportunities include a preliminary energy model analysis and measure development and should prioritize DAC.

• Barriers to System Modeling and Analytics: There is a need for more field validation of physics-based models. Market studies should address types of service providers, technology applications, and market barriers. Measure development and program opportunities include streamlined custom measure verification process and tools to increase program participation. Measure development should align with Cal TF Custom Measure efforts. Measure and program development should prioritize DAC.

• Barriers to Automated Building Commissioning: There is a need to measure the savings and cost-effectiveness of automated commissioning technology. Market studies should address technology and vendor landscape of smart building software, interoperability, and open standards. Measure development and program opportunities include streamlined custom process, tools, or hybrid measures to increase program participation in MBCx, CCx, and VCx. Measure development should align with Cal TF Custom Measure efforts and could include a hybrid or deemed approach for commissioning submeasures with higher effective useful life (EUL).
