Discover practical strategies for sealing and insulating crawlspaces to boost home performance and comfort. Learn from Dan Perunko of Balance Point Home Performance as he tackles moisture, rodents, and wildfire resilience. Ideal for professionals working on energy upgrades and crawlspace retrofits. Dan Perunko Dan Perunko is cofounder of Balance Point Home Performance Company. In 2006, along with Gavin Healy, Dan started a successful company providing full service home performance analysis, retrofits, consultations, and trainings. Dan works on new and existing

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.

Part two of this series will discuss installation best practices including line set construction and leak management as well as duct system design and installation. There is clear evidence that refrigerant release poses a significant hazard to our environment and Dan Perunko will review best practices to minimize this issue. Finally, this session will look at the new refrigerants options that are entering the market place. Agenda: Introduction and safety message Class poll: refrigerant types, global warming interactions, best practices

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. Accurately calculating the heating and cooling loads

This webinar equips participants with the knowledge to make smart, scenario specific choices when selecting heat pump water heaters (HPWHs). We'll begin with a brief overview of why HPWH deployment is a state priority, then explore the key factors that differentiate products, such as noise levels, ducting requirements, physical location constraints, electrical panel capacity, and more. The session concludes with an exercise exploring real world installation scenarios including garages, basements, indoor closets, outdoor closets, outdoor tankless replacements, and attics. Attendees

Part one of this series will start by covering best practices for line set testing, addressing refrigerant leaks and refrigerant line insulation. This session will focus on how efficient heat pump output relies on both refrigerant charge and total system airflow including: improving the airflow in existing systems, measuring and estimating airflow, and adjusting the airflow settings on various types of equipment. Agenda: Introductions and safety message Line set testing using high pressure nitrogen Line set testing and cleaning using
