Renewable Energy Systems and Net Zero Buildings
Chair:
Kristen Cetin, Ph.D., P.E., Iowa State University
Technical Committee: 07.05 Smart Building Systems
In recent years there have been significant efforts to implement net zero energy (NZE) buildings throughout the United States. This seminar covers several of these recent efforts, highlighting various alternative energy systems and new design strategies to reach NZE as well as how these buildings interact with the electric grid.
1 Net Zero Energy: What Metric to Use?

Before we know if a building has achieved Zero Net Energy (ZNE) status, we must know which metric is being used in the ZNE evaluation. The seminar presents the various metrics and their pros and cons being used in the ZNE definition from Site energy to Time Dependent Valuation energy and everything in between as well as their impact on the building systems design and energy code compliance.
2 The Net Zero Roadmap: The Net Zero Plus Electrical Training Institute
 |
Brett Moss, Electrical Training Institute |
Utilizing the Net Zero Plus Electrical Training Institute facility (one of the largest net zero commercial retrofits in the United States) as a dynamic case study, this presentation provides a roadmap to achieving zero net energy (ZNE) including discussion on the research, design strategies, and engineering processes that maximize energy efficiency and reduce consumption and costs. The presenter also discusses renewable energy systems and advanced technologies including microgrid systems paired with battery energy storage and measurement and verification (M&V) systems for achieving and maintaining ZNE status. Discussions also include various ZNE financing mechanisms and rebates.
3 Reaching Net Zero Energy: Single-Family Home Retrofit Strategies

Carlos Haiad, P.E., JCH Energy Management Solutions, Inc. |
Significant attention has been given to get residential new construction to reach zero net energy (ZNE) as already seen in many city (e.g. Austin), county (e.g., Tucson-Prima) and state (e.g., California) energy code requirements. This presentation focuses on retrofitting single-family homes to reach ZNE status. The presentation provides the results of retrofitting three blocks of homes with different levels of energy efficiency measures, demand response strategies, renewable energy systems, battery energy storage units, and electric vehicles charging stations in the quest to reach ZNE. The presentation also highlights potential electric grid impact of some of these technologies.
