Event Description Improved health and cognitive performance. Easier Title 24 compliance. Utility bill savings. These are the reasons to consider incorporating Heat Recovery Ventilators & Energy Recovery Ventilators (collectively Recovery Ventilators or RVs) into your next high-performance home project. The instructors are a high-performance home contractor and energy consultant, who together have specified and installed hundreds of RVs. They will draw on these experiences and data gathered from these units to better understand these mechanical ventilation systems and their benefits.

Event Description We all learned the principles of passive solar design in school – south facing orientation, strategic windows, thermal mass, etc., but the old rules don’t apply in the same way. In the meantime, Passive House building principles are folding into every-day construction. Modern buildings should still incorporate a range of passive strategies, but they need a new spin on the implementation to account for improved insulation, prevalence of high-performance glazing, and efficient HVAC systems and lighting.

Event Description This class teaches building department personnel how to use the ECC (formerly HERS) Registry to track the status of all of the ECC tests and inspections, as well as all of the other compliance documents: CF1R, CF2Rs, and CF3Rs. The Project Status Report generated by the registry is probably the single most valuable tool for building departments to ensure compliance with the energy code. Learning Objectives What the ECC program is in the energy code How ECC verification

Event Description Heat pump water heaters (HPWH) are becoming the standard in California. This free training will prepare your plumbers to install them correctly to avoid callbacks and achieve their full potential in terms of efficiency, capacity, longevity, and customer satisfaction. We’ll cover how they work, the range of models available on the market, the critical detail of air flow, and research on closet installs and condensation risk. You’ll come out prepared to add heat pump water heaters to your

Event Description Join us for an office-hours style open discussion focused on energy code compliance and performance modeling. This interactive session gives participants direct access to experts who can help clarify Energy Code requirements, compliance forms, modeling approaches, and energy modeling software. Bring your questions and real-world project challenges! The conversation will be guided by the needs and questions of attendees. The session will be led by Grant Murphy of In Balance Green Consulting, one of 3C-REN’s Energy Code Coaches.

Event Description This class will cover the basics of residential HVAC design following the industry standard and code-referenced ACCA Manuals J, S and D. It will discuss the four steps of the design process: Collecting information about the house. Performing load calculations (Manual J) Selecting equipment appropriate to the load calculations (Manual S) Design a duct system for efficiency and comfort (Manual D) It will also discuss some of the new technologies and software that has reduced the time it

Event Description Learn what the critical details are that make the difference between an accurate load calculation versus the rule of thumb guesstimate used by so many HVAC companies. Manual J myths, mysteries and truths will be revealed to attendees of this session. Learning Objectives Gain knowledge of the critical details needed to create accurate load calculations based upon ACCA Manual J procedures. Have a list of ACCA Manual J do’s, the mandatory requirements for an accurate load calculation. Have

Event Description Under the new 2025 energy code, HERS rating is now called Energy Code Compliance (ECC), but regardless of the name change, the 3rd-party verification process is still a great way to improve energy performance and meet the Title 24 Energy code. In this two-part course, we’ll cover what architects and builders need to know to successfully integrate ECC measures into residential design and construction. Part 1 will provide an overview of ECC verification, show how it fits into

Event Description Working through specific examples, we’ll help project teams identify strategies that have the highest impact for improving energy efficiency, comfort and indoor healthy environments in renovations and additions. Beginning with a focus on client needs and incorporating occupant goals, a high-performance remodel may be phased or done all at once, may focus on efficient equipment and appliances or more on indoor comfort, and may be very visible or mostly behind-the-scenes. Come learn the art and science of higher-performance

Event Description Join us for an office-hours style open discussion focused on permitting requirements for heat pump water heaters (HPWHs) and solar installations. This interactive session provides direct access to an industry expert who can help clarify general permitting processes, answer project-specific questions, and address common challenges encountered by contractors, designers, installers, and building professionals. Bring your questions and participate in an open dialogue designed to support successful project planning, compliance, and implementation. The session will be led by Reuben

Event Description With the growing occurrence of devastating wildfires, there’s an imperative to make buildings fire-safe and resilient. Passive House can support a clear pathway to achieve these goals. The class will review the latest science on wildfires and building safety, including the interplay among building structure, the surrounding landscape, community, and the Passive House methodology. We will dive into a toolkit with specific steps for analyzing and implementing fire-resilient Passive House strategies for your next building project Learning Objectives
