Retrofit electrification of existing buildings is critical for reaching energy and climate goals, yet there are many substantial challenges with replacement of heating, cooling, ventilation, and water heating systems. In particular, the extensive rework required to switch to heat pumps is complex, laborious, disruptive, bespoke, and expensive. In this webinar, researchers and practitioners will share about innovations and experience with emerging system design strategies that advance efficient electrification of single family and multifamily buildings. In part through grants funded by the US Department of Energy (DOE) and the California Energy Commission (CEC), the presenters have explored, installed, and monitored a variety of all-in-one, combi-, integrated-, and modular mechanical systems that combine most or all of the heating, cooling, ventilation, and water heating functions into pods or packages to simplify design, streamline installation, and enhance performance. This session will overview various technologies investigated, consider their tradeoffs, present an evaluation of their field performance and installation experience, and examine their applicability in different residential applications. Learning Objectives: Introduce and discuss combined mechanical equipment both in development for and available in the US residential building market today. Understand installation experience, system performance, and serviceability from case studies of equipment installations in occupied apartments. Compare and contrast with conventional mechanical equipment retrofits, and evaluate market applicability for these products. Share lessons learned from field demonstration research on product design for manufacturers, system design for building owners and design teams, and installation procedures for contractors.

Three RESNET standards combined: 1 - operations (HERS Index), 2 - the grid (CO2 Index) and 3 - embodied carbon (currently being written) provide capacity to analyze Carbon Usage Intensity. We'll explore time-of-use, load reduction and carbon sequestration in buildings at both the single-family and multi-family scale (500 units) to show cumulative impact. And discuss policy benefits of energy labeling and decarbonization for advancing energy equity, so that vulnerable populations can make informed housing opportunity decisions. While the content is technical in nature, the presenters will draw a direct relationship to equity in the context of who has access to low carbon housing and how carbon reductions strategies in both operational and embodied phases can be scaled to the housing industry at large through the standards and programs being developed through RESNET. While the early adoption of low carbon strategies have been pioneered in large part by well-funded custom single family construction, the approaches being discussed in this presentation are designed to bring much broader access to the industry at large and in so doing, increase resiliency. Further, we will explore equity from a climate justice lens to understand which communities are most directly impacted by the climate crisis that the residential housing sector is currently contributing to and provide the context and motivation for why building resilience through these initiatives is so critical. Learning Objectives: 1) Understand how the RESENT Carbon "Trifecta" allows calculation and analysis of blended metrics like Carbon Use Intensity. 2) Understand how such a blended metric facilitates a Whole Lifecycle Analysis at the residential scale and how close we are to being able to do this. 3) Understand the role that HERS Raters play in resiliency, especially in EJ neighborhoods, though the evolution of dynamic grid electrification, load management/reduction and carbon sequestration in buildings. 4) Understand the cumulative impact of simple materials substitutions at the scale of a residential development of 500 units.

In the 2006 International Energy Conservation Code (IECC), the primary residential provisions of the code (Chapter 4) consisted of four pages. That same chapter in the 2021 IECC is 21 pages long! Mandatory, prescriptive, performance, energy rating index, additional efficiency packages and UA trade-offs all combine to make IECC compliance complicated. Prescriptive compliance is increasingly more expensive and complicated to use, and the performance compliance option doesn’t allow consideration for high efficiency equipment. The energy rating index path provides a whole-house performance approach but has aggressive targets that are complicated with amendments for ventilation requirements and no requirements for quality assurance oversight of third parties. If the energy code’s primary purpose is to reduce energy consumption, why can’t we set performance goals and let builders figure out how to achieve it? One recent example of this approach is in Texas. Texas House Bill 3215 updated the state’s universal energy code compliance pathway to allow builders to use the energy rating index for energy code compliance across the state, in lieu of the state energy code or any stretch code adopted by municipalities. The legislation ratchets down target ERI scores to improve efficiency through 2028, allowing builders to plan for future efficiency requirements. Attend this webinar to learn how a simpler approach to energy code compliance can work, how it can be used to set a path to net-zero energy and how to implement it in your state. Learning Objectives: Learn about the changes and complexities of the IECC over time. Understand how the energy code can be simplified. Be able to describe how a simplified performance-based approach has worked in other states. Learn how a performance-based energy code approach can be used to get builders to net-zero homes more quickly.
