All-Electric Accessory Dwelling Units (ADUs)

All-electric homes are becoming more and more common in California. Accessory Dwelling Units (ADUs) are also becoming a common way to house people in California. This program is a unique opportunity to tour a new 1-bedroom all-electric ADU built above an existing garage in Long Beach, and to see the systems required to build all-electric: heat pumps, heat pump water heaters, induction ranges, and heat pump clothes dryers. Plus, this ADU was built using Structural Insulated Panel System (SIPS) and went up in 7 days; the ADU tested at Passivhaus airtightness as a result of the owner’s focus on the building envelope. Also incorporated into this ADU build is a Heat Recovery Ventilator and a 12-panel PV system. Nick Brown, President of Build Smart Group, is the owner and will speak about the need to electrify homes to meet California’s climate goals.

Learning Objectives

• Identify and describe the all-electric systems necessary to build all-electric ADUs
• Virtually tour the project and see first-hand the functionality of heat pump water heaters, SIPs panels, and Heat Recovery Ventilators.
• Define the difference between Net Zero Energy and Net Zero Carbon
• Detail the energy-saving benefits of a high-performance all-electric ADU
