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.


Toolkit for Identification, Characterization and Energy Evaluation of Low-Efficiency Rural Housing (GBCI Approved)

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.


AI and Building Energy Efficiency (GBCI Pending Approval)
Corina M. Cross, Siemens

View PDF of Presentation

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.

Boyd Lee encourages attendees to prepare themselves for “outside the box” thinking while sharing the story of CKenergy’s successful geothermal loop ownership program. His presentation proves the benefits of utility-owned geothermal ground loops for the utility, its customers, and the environment. Since 2013, the cooperative has paid to install over 1,340 geothermal ground loops for their customers. Boyd will discuss changes in the market they have observed and how this extremely bold step has produced significant financial wins for the utility’s operations and benefits to rate payers. This presentation is a must for utility marketing, cost of service and rate managers, and other decision makers as well as regulatory commission staff and other industry professionals.


Keeping Cool: Refrigeration Thermal Energy Storage for Refrigerated Facilities (presented remotely) (GBCI Approved)
Lee Shaver, Slipstream
Greg Marsicek, Slipstream

View PDF of Presentation

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.

R19 Windows Are Real!
Greg Clarahan, LiteZone® Glass

View PDF of Presentation

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.

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.
