Heat Pumps are a big part of the solution to meeting California’s climate goals in buildings. In plain terms, they’re reversible air conditioners and have been around for over 100 years. This session is designed for HVAC contractors, builders, and others who want to understand how to install heat pumps right. We will cover how heat pumps can add value to your business, how heat pumps work and various configurations, and how to overcome common installation hurdles. Hurdles covered include
This is class 4 of 6 in 3C-REN’s High Performance Fundamentals Certificate series. Earn a 3C-REN certificate of completion after finishing the series and passing short quizzes at the end of each class. This series will be hosted twice throughout 2023. Having gained a solid understanding of high-performance building enclosures from classes 1 through 3 in 3C-REN’s High Performance Fundamentals series, participants are well-prepared for this class, which will provide a foundation in the use of heat pumps for both
This is class 5 of 6 in 3C-REN’s High Performance Fundamentals Certificate series. Earn a 3C-REN certificate of completion after finishing the series and passing short quizzes at the end of each class. Do you have any customers who wait a long time to get hot water somewhere in their house? Do you know someone who is frustrated watching the water run down the drain while waiting when outdoor watering is restricted due to drought? Have you ever wondered why a
Event Description: The 2025 code cycle will see large revisions to the HERS (Home Energy Rating System) Rating program. To prepare attendees to understand these changes, this virtual forum will first introduce the history of HERS Rating, what the program has accomplished, and why HERS Rating is important for code compliance. With this knowledge, attendees will be ready to learn what changes are anticipated for the 2025 code cycle and how it will impact their work. Learning Objectives: After attending this forum, participants will be able to summarize the history of the HERS
Course Overview There are several design considerations for individual heat pump water heaters. In addition, heat pump water heaters can be an effective strategy to reduce grid peak loads. This course will provide an overview of heat pump water heaters and associated code requirements. The course will take a deep dive into design considerations discussing sizing, venting configurations, load shifting, and installation best practices. This course draws from experience of working through hundreds of heat pump water heater retrofits with
This is class 6 of 6 in 3C-REN’s High Performance Fundamentals Certificate series. Earn a 3C-REN certificate of completion after finishing the series and passing short quizzes at the end of each class. This class is designed to prepare building practitioners, who have basic to advanced knowledge of residential building, to assist homeowners on their pathways to electrification. We will cover all phases of the assessment process from understanding homeowner goals and setting expectations, through a methodical investigation and documentation of existing
Join Russ King, CEO of Coded Energy Inc., and Nick, an energy consultant, as they make the case why energy consultants should add HVAC design to the services they offer. Title 24 consultants have all the data they need to do HVAC load calculations, and Russ has recently introduced new software that simplifies the workflow to create a Title 24 compliance model and a HVAC load calculation model, but only build a single model. Russ and Nick will show how
As more California homeowners begin electrifying their homes, heat pump installers will be faced with the challenge of navigating electrical panel challenges including condition, capacity, fitment, supply chain, etc. With panel and service upgrades being costly and complex, it’s important for practitioners to understand their options for running new circuits. In this session, you’ll hear from Electrify My Home discuss real-world electrical panel scenarios including visual assessments, electrical load calculations, and examples of different solutions for “making it work.” Learning
All-Electric in Design & Construction Series Incorporating all-electric systems into residential and small commercial projects can be a bumpy road, but understanding the nuts and bolts of specific systems helps smooth out the process. By identifying and reviewing specific products and manufacturers, we’ll provide architects, builders and owners with the tools to easily go from design and permitting to construction and operation. This is a five-part series to pick-and-choose, or take all five: Part 1: Ductless Heat Pumps will address ductless

Zone control is a popular strategy for addressing different climate zones in a home. Many customers and contractors newer to heat pumps are drawn to multi-split systems that utilize a single outdoor unit to run multiple air handlers, but there can be unintended comfort sacrifices if not done carefully. In this webinar we will focus on various approaches to zone control for efficient and comfortable outcomes. We will compare traditional zoning with zone control, multi-split systems, multiple 1-to-1 systems, and
