Advanced Metering
Isaiah Borel, CEM, Linn County Rural Electric Cooperative
Location: Salon 3

Advanced Metering Infrastructure (AMI) is modernizing the grid to bring more visibility and control into utility departments to save money and energy. Linn County Rural Electric Cooperative replaced all analog and digital meters with advanced meters back in 2019.This session will explore what AMI is and how using the data has been an asset for Linn County REC. With millions of data points coming back daily from AMI, a Metering Data Management System (MDMs) can help to determine which data is the most important.

Tomorrow’s utilities will always be learning and shaping the way we move forward. Data tells a story; utilities need to be listening. AMI is having a big impact on utility rates, demand-side management, and consumer behavior that is leading to a redesign.  Utilities and Consumers now have 2,880 usage reads per month compared to a single record. Before AMI, utilities have traditionally made assumptions on how consumers use energy. AMI is allowing a new focus towards mass behavior efficiency and optimization that has been previously limited. At Linn County REC, we are still writing the future on where AMI will direct us.

11:15am / Breakout Session 2


AI and Building Energy Efficiency (GBCI Pending Approval)
Corina Cross, Siemens
Location: Skinner A

Dynamic VAV Optimization applies AI to intelligently optimize AHU static pressure and supply air temperature setpoints, a challenge for traditional systems. DVO bases its decisions on temperature and humidity data collected from existing sensors throughout the building. Its AI-powered algorithm then determines heating and cooling requirements and sends setpoints to your HVAC system that cost-effectively and sustainably ensure better occupant comfort. The energy savings result from reset strategies applied to the static pressure and discharge air temperature setpoints. For buildings that already have these strategies adopted, the energy savings result from dynamic controllability, faster feedback and loop control, and machine learning capabilities that will help predict demand conditions.

Lessons Learned from COVID-19 and its Impact on HVAC Design (GBCI Pending Approval)
Mike Zorich, IMEG Corp.
Eric Henderson, IMEG Corp.
Location: Skinner B

When the COVID-19 pandemic reached the U.S. in early February 2020, so much was unknown about the virus, how it is transmitted, and how many patients would ultimately end up hospitalized with it. Now, a year and a half later, we have much more information on the virus and how it is transmitted. We can analyze how COVID-19 impacts a facility’s infection control strategy and the steps that should be taken to help protect building occupants in schools, university classrooms, commercial offices, hospitals, and more. This presentation, given by two IMEG healthcare design experts, will examine the pros and cons of such strategies as increased ventilation, filtration, AHU/coil-level UVGI, room-level UVGI, humidification, and needle point/bipolar ionization. The presentation will also cover how the virus affects infection control strategy, the necessary system modifications facilities need to make, emergency preparedness, flexibility, and our lessons learned from the past year.

R19 Windows Are Real! (GBCI Pending Approval)
Greg Clarahan, LiteZone® Glass
Location: Skinner A

LiteZone® is a proprietary new insulating glass technology that makes possible very high window insulating values. LiteZone® can achieve up to R21.7 centre of glass and up to R18.7 for an overall window, including both the glass and frame. LiteZone® glass units embrace the need for a thicker assembly to allow much larger thermal breaks necessary to achieve very high overall window insulating values. LiteZone® allows the use of generous glass areas in highly energy efficient buildings. The presentation will explain in detail the various technical elements of how LiteZone® insulating glass is constructed to achieve very high window insulating values and a 60-year life span. Why thicker insulating glass units are required to achieve R12 to R19 window insulating values will be illustrated. Examples will be shown of how to install thicker LiteZone® glass units in a wall without a traditional frame to achieve a higher performing, lower cost, and minimalistic window installation.

Keeping Cool: Refrigeration Thermal Energy Storage for Refrigerated Facilities (GBCI Pending Approval)
Lee Shaver, Slipstream
Greg Marsicek, Slipstream
Location: Skinner B

Thermal energy storage (TES) provides an established means for facilities to reduce peak demand, shift electricity load to off-peak hours, and create grid flexibility. Recent TES developments in energy intense and cold temperature refrigeration operations can now yield significant energy (kWh) savings as well. We will provide an overview of research conducted in Minnesota and Illinois on TES for buildings with refrigeration systems, including refrigerated warehouses and grocery stores. Our research focuses on investigating two primary TES technologies: phase change materials and thermal flywheeling. We will discuss how TES can lower operating and maintenance costs for facility owners and provide grid operators with tools for grid management. We will present insights gained during interviews of manufacturers and buildings owners/operators. Lastly, we will also highlight the results of our energy modeling analysis, including economic results.

Toolkit for Identification, Characterization and Energy Evaluation of Low-Efficiency Rural Housing
Diba Malekpour Koupaei, Iowa State University
Sponsored by IEDA
Location: Skinner C

Residential buildings consume a significant portion of energy and electricity. The residential housing stock in rural areas of the U.S. is generally more likely to be older and less energy-efficient than those homes built in more urban areas. To improve the energy efficiency of such residential buildings, it is important to understand the energy performance characteristics of building in rural areas. This can help to better define which buildings are in greatest need of energy retrofits. In this research, through collaboration with the communities of Ames, Bloomfield, and Cedar Falls, Iowa, U.S., building energy use data and building characteristic data (from energy audits and assessors data) was used to assess the overall characteristics and energy performance of rural residential buildings. Such evaluations can be used to design policies and programs that benefit both individual building occupants, and also address absolute levels of consumption now and moving forward.

 

POSTER PRESENTATIONS


Documenting the Expanding Benefits of Strong Energy Codes: How Energy Codes Impact Community Health
Nicole Westfall, Midwest Energy Efficiency Alliance
Chris Burgess, Midwest Energy Efficiency Alliance

Building energy codes have a clear, well-understood impact on the energy use of a building, resulting in lower energy costs for building owners and occupants. However, the benefits of strong building energy codes extend far beyond traditional energy cost savings. Improved resilience, better indoor air quality and greater comfort are all being studied, and found, in buildings with more advanced energy codes. Direct societal health benefits also accrue when more efficient building energy codes are adopted and enforced. This presentation will discuss the results of a recent study that examines the impact updating building energy codes can have on societal health. The research calculates the health-associated benefits of updating a given states’ current residential building energy codes, including state specific amendments, to the unamended 2018 IECC using EPA’s Health Benefits per Kilowatt Hour tool. Results will focus on Midwestern states, with an emphasis on impacts in Iowa.
