SUMMARY:Electrify Efficiently: Overcoming Heat Pump Objections (Part 1 of 5)
DESCRIPTION:Heat Pumps are quickly gaining traction as a preferred HVAC and water heating technology. California has a goal for 6 million installed heat pumps by 2030\, and state plans indicate that new gas furnace and water heaters will not be permitted after 2030. While the path forward for heat pumps seems clear\, the technology is still foreign to most homeowners. To meet the above-mentioned goals\, contractors and other industry professionals must arm themselves with the knowledge (and sometimes the data) to dispel myths about heat pumps. \nIn this webinar\, you’ll hear from Larry Waters\, an HVAC industry veteran who switched his focus towards home performance in 2010 and towards inverter heat pumps in 2014. With over 400 heat pump installations under his belt\, Larry’s heard just about every objection in the book and will relay best practices for responding to such objections.

SUMMARY:Introduction to Heating and Cooling Load Calculations for Electrification Projects
DESCRIPTION:In this webinar\, Judy Rachel will explain what a heating and cooling load calculation is and how it provides essential information for the successful implementation of electrification projects. Beyond providing the essential information for properly sizing a residence’s HVAC system\, the heating and cooling load calculation informs electrification project design and planning in significant ways. In addition\, this presentation will explore the business case for this important planning step within the construction process. \n  \nAccurately calculating the heating and cooling loads for a building provides the information necessary to choose appropriately sized space conditioning equipment. When pursuing electrification using right sized\, typically\, lower capacity HVAC equipment you will frequently negate the need for panel upgrades which provides a significant advantage in electrification projects. This contributes significantly to reducing project costs\, while saving on energy consumption and ongoing costs to comfortably condition a given home.

SUMMARY:2026 Title 24 Part 6 California Energy Code Changes: What HCAI Projects Need to Know Webinar
DESCRIPTION:The 2026 code cycle places increased emphasis on energy efficiency\, electrification\, system performance\, and documentation quality. For HCAI projects\, these changes influence not only system design\, but also coordination\, regulatory review\, and long-term operational outcomes. Hospitals that understand these requirements early are better positioned to reduce energy use\, control operating costs\, and improve system reliability while maintaining full compliance. For projects involving seismic upgrades\, infrastructure improvements\, or Non-Structural Performance Category (NPC) compliance\, the transition introduces both risk and opportunity. Proactively aligning design decisions with the 2026 code requirements can help avoid redesign\, streamline HCAI review\, and deliver lasting operational and energy savings. This session provides a practical\, technology-aware overview of the most important 2026 code changes affecting hospitals and offers guidance on how to prepare HCAI projects for a smooth transition. \nLearning Objectives: \n\nIdentify key hospital code changes for 2026\nRecognize how energy regulations impact MEP system design\nReduce project risk and delays through early compliance planning\nImprove long-term energy efficiency and building performance

SUMMARY:Mechanical Rooms: Strategies for Electrification Retrofits in Homes
DESCRIPTION:For as long as we’ve built homes we’ve been using some kind of combustion to heat them. As a result\, our buildings are designed and constructed to safely manage the operation of gas appliances. In this webinar\, Dan Perunko of Balance Point Home Performance will look at mechanical rooms as we transition from gas appliances to electric appliances. There is an opportunity for contractors and designers to offer their clients additional efficiencies beyond those offered by the change to electric appliances. We will identify easily overlooked building enclosure and mechanical changes that can be incorporated into an electrification retrofit project. This three-hour webinar is based on completed projects and will have images of floor plans that illustrate the complexities of combustion appliance mechanical spaces and the opportunities available when they are electrified.

SUMMARY:Ventless Combo Washer Dryers
DESCRIPTION:Washers and dryers account for anywhere from 8-10% of the energy use in our homes and a significant amount of our water use. Heat pump dryers are rated ENERGY STAR’s most efficient dryers on the market\, using roughly 75% less energy than a typical electric resistance or gas dryer. They use heat pump technology to move heat rather than create it\, and have many benefits. Manufacturers from GE to Samsung to LG offer combo washer + heat pump dryers that wash and dry a complete load of laundry in the same machine. They’re lauded for their space saving\, convenience\, and energy efficiency\, as well as the advanced wash cycles and smart features they offer. As the market for this technology grows\, we’ll take a look at the big advantages and minor challenges of switching to a combo unit. Not only do combo washer + heat pump dryers have the potential to save time and improve a homeowners’ washing/drying experience\, they greatly reduce energy use required to dry clothing. Most also plug into a 120-volt outlet\, helping homes with gas dryers electrify this end use more easily. Join us for a 45-minute webinar with a live demo\, in which we explore: What is a combo washer + heat pump dryer and how does it work? What are the advantages and disadvantages of combo washer + heat pump dryers? What models are on the market? How are these appliances performing from a service and warranty perspective? How did the current models of combo washer + dryers overcome challenges to create a new way of doing laundry? What are the expected time and energy savings from combo washer + heat pump dryers?

SUMMARY:Net Zero Energy Buildings Now and What’s Next
DESCRIPTION:Buildings tend to be the primary energy consumer in the U.S.—and amid rising utility prices and concerns about the impacts of climate change\, efforts are being made to incorporate energy saving strategies into commercial building design\, construction\, and operation. The concept of a Net Zero Energy building\, which produces as much energy as it uses annually\, is a reality in most regions. These buildings often come with added benefits that include improved comfort and resilience. In this online event\, our panelists will discuss Net Zero Energy buildings. Presenters will clarify what these terms mean and how they compare with other classifications\, such as Net Zero Carbon or Living Buildings\, and introduce Future‑Ready building concepts. The session will feature case studies\, explore why clients made this choice\, and highlight how the current market for these buildings is evolving today.

SUMMARY:Practical and Efficient Hot Water Delivery: Meeting Hot Water Demand with Heat Pump Water Heaters
DESCRIPTION:On average Californians consume less water than the residents of other states. Even so there is a need for us to conserve even more water. The construction community has an opportunity to further reduce residential water use in ways that do not feel like conservation to customers. In this class\, Dan Perunko of Balance Point Home Performance looks at changing the way hot water is stored and delivered to the tap in residential buildings. The theory behind our approach is called “Structured Plumbing”. This will be a practical class focusing on how to install or modify hot water plumbing following the principles of “Structured Plumbing”. The presentation is based on completed projects including retrofits and new construction.

SUMMARY:Optimizing Ducted Heat Pumps for Residential Electrification: Efficiency Comfort and Low Loss Duct Systems
DESCRIPTION:This three hour class  will deal with low loss duct systems. The relevant performance factors are: duct leakage\, duct conduction\, room by room airflow\, and system airflow. We will review design\, installation and commissioning details as they relate to duct system performance for each of these performance factors. These performance factors can be applied to both conditioning and ventilation system ducts. We have designed\, built and commissioned both retrofit and new construction projects that exemplify the concepts covered in class. Course content will include design examples\, photos installations\, and test results from commissioning.
