Course description Part 1 of 2  Crawlspaces come in all shapes and sizes including shallow or hillside, and crawlspaces adjacent to conditioned spaces. The geometry of a crawlspace is an important factor when deciding where to establish a continuous air barrier. Ultimately the insulation will follow and remain aligned with that air barrier. In this course, Dan Perunko of Balance Point Home Performance will present air sealing and insulating strategies for various crawlspace types, along with the myriad benefits effective

Course description Part 1 of 3  This full day webinar focuses on the unique residential loads and energy code encountered in the Dry Climate of California. The material covers the basic science behind ACCA Manual J load calculations and Manual S equipment selection. During this session, a sample plan is entered into Wrightsoft first using the 1975 code, since many homes meet these criteria it provides a touchstone for contractors in equipment sizing. The plan is then altered to meet

Course description Part 2 of 2  Many existing crawlspaces require remediation prior to other energy upgrade work, including attic or electrification upgrades. This course examines retrofits of vented and unvented crawlspaces, tradeoffs between each crawlspace assembly, and the crawlspace assembly's impact on the home's overall performance and comfort. From home durability to occupant safety and comfort, Dan Perunko of Balance Point Home Performance will address moisture and vapor sources, rodent control, as well as strategies to reduce wildfire ember intrusion.

Course description Part 2 of 3  This full day webinar focuses on the principles involved in designing residential duct work. A practice session is included where attendees sketch a duct design based on the floor plan from the Manual J/S developed in the first session, ACCA Dry Climate Manual J and S, with Wrightsoft. During this session, Residential Equipment Sizing, (Manual S) is reviewed and duct design concepts such as location of registers, the effect of supplies and returns on

Course description Part 3 of 3  This full day webinar reviews the basic principles involved in designing residential duct work. The Wrightsoft floor plan developed on day one in Wrightsoft is used in this duct design session. The set-up of Wrightsoft to match best practices is covered and a portion of the presentation is a practical session demonstrating the process of selecting registers. A sample register schedule is reviewed and explained. The session begins with a brief review of the

As our electricity supply becomes cleaner, due to an increased use of renewables for generation and a growing number of local ordinances prohibiting gas installs in new homes, electricity becomes an attractive fuel source to designers and builders interested in reducing residential greenhouse gas emissions and creating zero carbon homes. Dan Perunko of Balance Point Home Performance will present on efficiency gains, and overcoming common installation pitfalls from electric heat pump water heaters in new and existing buildings. Class discussion

Electrification is taking form in California. Gas water heaters are being phased out in the Bay Area by 2027 and over 70 municipalities have policies phasing out gas appliances. The massive transition from gas to electric will spark giant demand for all trades, including plumbers. In this session, Electrify My Home will introduce unique business opportunities for plumbers with a focus on heat pump water heaters, strategies for collaborating with other trades (e.g., electricians), and the importance of comprehensive electrification

Part 1 of 2  Part one of this series will provide an overview and introduction to mini split systems. Dan Perunko will also address the pros and cons as well as the relative efficiencies available for each system. In this session, we will also review how these smaller systems provide advantages for mechanical system design and layout. Agenda: Introduction and safety message Overview types of mini split systems Pros and cons of the different system types Load calcs, system layout

Waiting one to two minutes for hot water is excruciating. Yet we don't design our homes around this important goal of minimizing the time to get hot water at the tap. This intermediate level webinar covers the science of hot water distribution with guidelines to get Hot Water Time to Tap (TtT) down to 10 seconds, 20 seconds flat. This webinar will cover architectural compactness, pipe sizing, strategies for recirculation loop systems, and compare the energy efficiency of various systems.
