Presentations and speakers:
• "High Performance Attics for Zero Energy Homes" by Iain Walker, Scientist, Lawrence Berkeley National Laboratory
This presentation will discuss the thermal and moisture performance of lower-cost approaches to high-performance attics. The presentation will answer questions such as: Are these attic spaces truly inside the home so we can reduce HVAC system losses? What are the moisture concerns with new construction practices? How can we best address these moisture issues? It will conclude with recommendations for construction codes/standards to enable lower-cost, durable high performance attics. This project was funded by the California Emerging Technologies Program and the California Energy Commission’s Electric Program Investment Charge (EPIC) program.
• "Assessment of Horizontal Self-Contained Display Cases Using Natural Refrigerant" by Edwin Hornquist, Senior Emerging Technologies Program Manager, SCE
Self-contained refrigerator/freezer display cases are used by many commercial retailers, including supermarkets, mass merchants, c-stores, drug stores, and dollar stores. They maintain products at desired temperatures while displaying them for sale to consumers. The use of natural refrigerants in these systems (including propane, CO2, and isobutene) has a potential for significant energy and demand savings as well as environmental benefits.
• "Computer Gaming Systems: Energy Efficiency without Performance Compromise" by Leo Rainer, Principal Scientific Engineer Associate, Lawrence Berkeley National Laboratory
Two-thirds of Americans play computer games. Although among the most complex and energy-intensive plug loads, gaming has been largely overlooked in energy R&D and policy. Computer gaming in California used 4.1 TWh in 2016—5% of residential electricity and 20% of miscellaneous electric loads. While simultaneously quantifying efficiency and gaming performance is highly problematic, evidence suggests that efficiency can be improved while maintaining or improving user experience. This project was funded by the California Emerging Technologies Program and the California Energy Commission’s Electric Program Investment Charge (EPIC) program.
