2026 Title 24 Part 6 California Energy Code Changes: What HCAI Projects Need to Know Webinar
2026-02-26 09:00 - 10:00
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.
Learning Objectives:

Identify key hospital code changes for 2026
Recognize how energy regulations impact MEP system design
Reduce project risk and delays through early compliance planning
Improve long-term energy efficiency and building performance

Mechanical Rooms: Strategies for Electrification Retrofits in Homes
2026-02-26 09:00 - 12:00
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.

Ventless Combo Washer Dryers
2026-02-26 12:00 - 12:45
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?
