Webinars

Welcome to the 2019 ETCC Webinar Series!

The Emerging Technologies Coordinating Council aims to share knowledge and strengthen capabilities of the emerging technologies community. To this end, the ETCC has launched a free quarterly webinar series to highlight current and/or recently completed projects by the ETCC members. These hour-long webinars will feature two to four projects across a wide variety of energy-efficient technologies and customer solutions and allow time for Q&A from attendees. To receive notifications about upcoming webinars, please subscribe to our email list.

High Performance Attics for Zero Energy Homes

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. (Video | Slides | Report)

Assessment of Horizontal Self-Contained Display Cases Using Natural Refrigerant

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. (Video | Slides | Report)

 

Computer Gaming Systems: Energy Efficiency without Performance Compromise

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. (Video | Slides | Report)

Teren Abear

LED Track Lighting

Teren Abear, Technology Area Lead, SCE

This project evaluates two main approaches to using LED technologies in existing track-lighting applications. Both dedicated LED-specific track heads as well as retrofit options using screw-base LED lamps for use with traditional halogen lamps were tested for photometric and energy savings performance.

Dynamic Air Balancing for Commercial HVAC Systems

Hardik Shah, Senior Engineer / Program Manager, GTI

By adding additional thermostats to create micro-zones within zones managed by AHUs or constant volume HVAC systems, the technology promises potential energy efficiency savings in commercial buildings through air flow balancing, predictive weather analytics, better occupancy detection, enthalpy economizers, demand control ventilation, and multistage thermostat controls. There is also potential for demand response. (VideoSlides)

 

Milica Grahovac

Costs and Benefits of Community vs. Individual End-Use for Solar Water Heating

Milica Grahovac, Senior Scientific Engineering Associate, Lawrence Berkeley National Laboratory

The project develops and implements an analytical model to quantify the relative costs and benefits of community-scale solar water heating systems in comparison to individual systems under a wide range of climate zones and conditions in California. This presentation focuses on the solar thermal system energy use simulation and provides comparative results at individual and community scale. (VideoSlides)
