What You Need to Know About 25 C Homeowner Energy Efficiency Tax Credits

If you make qualified energy-efficient improvements to your home after January 1, 2023, you may qualify for a tax credit of up to $3,200. Beginning this year, no credit will be granted unless items are produced by qualified manufacturers and the taxpayer reports the PIN for the item on their tax return. This session covered:

• An overview of the 25C homeowner energy efficiency tax credit
• The status of the PIN assignment system
• How AHRI can provide a PIN
• A system demonstration

Flammable Refrigerants (A2s and A3s) – What You Need to Know

Even though the transition to A2L refrigerants is not yet complete, some policy makers at the federal and state levels are discussing a follow-on transition to “ultra low-GWP” refrigerants which, at the current time, are categorized by ASHRAE as A3 (flammable). The panel addressed:

• The current state of discussion in states and the federal government
• The potential path toward the widespread use of A3 refrigerants
• What this could or would mean with respect to technician training and safety

Decarbonizing Commercial and Industrial Heating with Hydrogen Part 1: What is the Decarbonization Potential?
Cohost: GTI Energy

The first session in this two-part series:

• Introduced the current state of research to define the upper practical limit of using H2 to decarbonize large commercial and industrial heating equipment currently using natural gas, the structure of the project for the California Energy Commission with partners GTI Energy, UC Irvine, EPRI, AHRI, and other industry partners (AHRI members)
• Provided the context for displacing natural gas in heating equipment with H2 as a blend or through full conversion to 100% H2, with an overview of key developments and demonstrations in North America
• Described parallel testing methods and results regarding common materials of construction and impacts of being exposed to hydrogen combustion environments

Decarbonizing Commercial and Industrial Heating with Hydrogen Part 2: Recent Results from Testing Boilers, Furnaces, Water Heaters, and Other Equipment
Cohost: GTI Energy

The second session in this two-part series:

• Continued to describe the testing methods employed at GTI Energy and UC Irvine laboratories to test multiple boilers, water heaters, furnaces, and other commercial/industrial equipment and establish practical upper limits of hydrogen blending into natural gas, including considerations for hydrogen safety and novel emissions sampling techniques
• Reviewed the results concerning impacts on heating capacity, efficiency, NOx/CO emissions, CH4/H2 slip emissions, operational safety, and other considerations for the 10+ equipment tested
• Reviewed the project’s preliminary technoeconomic assessment of using H2 in commercial/industrial facilities throughout California and review the technical survey of current research regarding the practical limits of using H2 in heating equipment

Adiabatic Humidification Technologies for Decarbonization

This presentation explored how humidification and evaporation technologies fit into decarbonization strategies, with a particular focus on energy efficiency benefits that can be unlocked with evaporative technologies. Attendees reviewed indoor humidity terminology and commonly available technologies before taking an in-depth look into how those products fit into decarbonization strategies. See the presentation here.

Supporting Healthy Buildings through Humidity Control

This session explored the links between humidity and health in schools, workplaces, and homes, and provided practical approaches for achieving optimal humidity levels. In addition to ventilation and filtration, humidity control is an important component of healthy indoor environments. Both recent and historical research have demonstrated links between humidity control and the health of building occupants, as well as control of infectious aerosols. See the presentation here.

Thermal Energy Storage: Current Technologies and Innovations

Attendees learned about the latest innovations in thermal energy storage and why it is important, especially as it relates to the new investment tax credit included in the Inflation Reduction Act of 2022. The presentation covered the types of products that are commercialized (i.e., rooftop packaged units, chillers, campus-wide tanks), the economic and carbon-reduction benefits to end-users, as well as the benefits to the grid. See the presentation here.

VRF Test Procedure and Efficiency Rating Update

This session provided a summary of the most notable changes in the new VRF test procedure, including an in-depth review of the CVP and associated Appendix C and H sections of the standard. There was a review of definitions, calculations, other significant requirements to meet the CVP, and the budgeting system. See the presentation here.

What You Need to Know - A Closer Look at the Ongoing Implementation of the Inflation Reduction Act Incentives
