Heat Pump technologies have evolved greatly in efficiency, durability and popularity in recent years. In this class you will learn how heat pumps work to heat and cool homes as well as domestic water heating. This class will detail proper design and installation as well as the common mistakes that lead to poor performance, call backs and high bills. This class will explain how heat pump efficiency is measured and how to select heat pumps for performance and comfort. If
California’s 2022 Title 24 Residential Energy Code all but requires high-performance walls with exterior insulation while higher-performance home designs, like Passive House, requires continuous exterior insulation. This class examines how to design and build high-performance wall assemblies that deliver energy efficiency, reduce space conditioning loads, and do not lead to water or moisture failures. Presenter Steve Easley will delve into the best installation practices for air barrier/sealing to meet and exceed building codes.
This class will look at specific building examples, covering a broad spectrum of building types and architectural styles in multiple climate zones. We’ll review details to understand the building science behind each project. Attendees will leave with a clear understanding of the broad applicability of Passive House for all building types and climates. New & retrofit, Historic restoration, Commercial & complicated.
Part 5 of 5 - April 21, 2023 (8:30am - 12:30pm) This training series will focus on the design, commissioning and operational issues associated with heat pumps and heat pump systems with a focus on how this type of equipment can facilitate electrification of buildings and building systems. The content will be divided into five half-day sessions. Each session will stand alone, but the different training modules will also be inter-related. Ideally people interested in using heat pumps as part
This webinar will provide an overview of improved and modified tax credits in the Inflation Reduction Act (IRA) that can improve the economics of residential new construction with energy efficient and clean energy upgrades. Topics to include Section 48/48E commercial credit, Section 179D commercial credit, Section 25D residential credit, and more. The practical application of IRA incentives continues to unfold and this webinar will provide a starting point for industry to understand its current state.
California’s new Title 24 energy code and Passive House recommends high performance attics. Summer attic temperatures can easily add ½ to 1 ton of air conditioning load. The 2016 and 2019 T-24 energy codes require these loads be mitigated. These codes prescriptively require attics and roofs with multiple layers of insulation in what seem to be in confusing and contradictory locations. This class examines how to design and build high performance attics and roofs assemblies that delivery energy efficiency and

Improved design, installation and commissioning practices lead to a dramatic improvement in building energy consumption, indoor air quality, and comfort. There are six performance factors that can be applied to HVAC design, installation and/or commissioning. In the Optimizing Residential Forced-Air series, we will review how each factor can be specified at design, implemented during installation, and tested/adjusted during commissioning. We will also look at how we can redesign our approach to high performance HVAC systems to support CA climate goals,
As we start turning our attention to the existing building stock, electrification retrofits are becoming increasingly important to achieve our emission goals and have healthier homes. Come explore how to approach an electrification retrofit, what are the constraints and opportunities for multifamily buildings with different configurations and how it is shaped by electrical infrastructure and available technology. Gain an understanding of what an electrification retrofit looks like by working through example project(s) in class.
Amruta Khanolkar of the New Buildings Institute will give an overview of the emerging, retrofit ready 120V heat pump water heaters (HPWH) and findings from the California statewide field validation effort. This course will present the retrofit market opportunities and limitations with this emerging 120V HPWH technology. This class is for program managers, engineers, policy makers, installers, and California building jurisdictions.
Our final class in this series will bring this home to cover the evolution of Passive House design here in California. We’ll review up to four specific projects located in Northern California, including a Sacramento project. Details for each project will be shared to gain an understanding for how this approach varies across our local climate zones, and how Passive House may be cost-effectively implemented in our region. Attendees will leave with a clear understanding of how the Passive House
Comfort problems can occur in homes even when the equipment appears to be working perfectly well. Most comfort problems are related to design issues and can be easily diagnosed using basic design principles and simple diagnostic tools. This class will cover the most common comfort complaints, the diagnostic tests, how to interpret the results and how to use industry standard design principles to suggest solutions. Learning objectives: Understanding the most common symptoms of comfort problems vs. equipment problems Understanding how
