Alexis London Kevin Frost | Bringing sustainability to Wisconsin affordable housing: the Bayview Foundation Bayview was formed in 1966 to support culturally diverse, low-income families in Madison, WI. Bayview is in the final year of an effort to revitalize its diverse community. The first two phases of the project are complete, with the third to be complete later this year. The development consists of a new community center and 130 apartment units, the majority of which are Section 8 housing to maximize affordability for low-income residents in Madison. BIOs

Rachel Ruekert | Words Matter in a BAS Submittal ASHRAE Guideline 36, complicated designer control sequences that might emulate ASHRAE 36 or even packaged Roof Top Units....these devices, these systems don't work by magic though people might think so. So, what is the best way to verify that the Owner, the Designers, the Mechanical Contractor, the Electrical Contractor, the Controls Contractor, and the Cx Provider all understand how the control systems work as shown in the project control submittal with its sequences and the interdependencies in the exact same way? The answer to this question is of course, a controls page turn meeting! BIOs

Spencer Ingaldson | Leveraging groundwater to bring geothermal everywhere Darcy Solutions groundwater based geothermal systems provide 100+ tons of capacity per well by utilizing a heat exchanger placed in the aquifer. This leap in technology and capacity is drastically reducing the amount of space needed to implement a geothermal system. Darcy’s team of geologists are able to precisely design a system that is capable of leveraging constant groundwater temperatures to operate with unbalanced loads, with no limit to the size of the system. Darcy’s technology is currently operating at many Midwest locations, including Hospitals, K-12, Municipal Facilities and Universities. Many more projects are currently in construction in Wisconsin. This technology is allowing new and existing building owners to decarbonize, lower their operating costs and leverage the Inflation Reduction Act. BIO Spencer Ingaldson serves as the Chief Development Officer at Darcy Solutions, overseeing Business Development, Sales, Marketing, and Applications Engineering. With over 16 years of specialized experience in HVAC systems sales, Spencer brings a wealth of knowledge in applied HVAC systems, along with a deep understanding of the commercial and industrial HVAC markets. A graduate of Purdue University with a degree in Mechanical Engineering, Spencer also holds a USGBC-LEED Accredited Professional certification, underscoring his commitment to sustainable building practices. |

A New Perspective on the Modern Microgrid
With over 8GW of power installed globally, Clarke Energy is an industry leader in on-site power generation systems. This presentation will aim to explain the benefits of distributed generation projects with several Clarke Energy case study examples. We will also explain the use of different technologies and applications, as well as current trends in the market. More specifically, we will go into the discussion of Microgrid schemes and incorporating renewable energy sources while also utilizing the waste heat from the system. BIO Adam Sandstrom is the Sales & Marketing Coordinator for Clarke Energy USA - A Kohler Company. He has been with Clarke Energy for two years and has a deep interest in the development of microgrid and hybrid technologies as well as renewable natural gas systems. Adam is an active member in several regional and national organizations to include the Midwest Cogeneration Association and the American Biogas Council. |
Ralph Muehleisen | Recent and Coming Advances in Heat Pumps As part of building and industrial electrification, electric heat pumps are replacing gas driven furnaces and boilers for hot water, space, and low-temperature processing heating. While the current generation of heat pumps are able to replace residential furnaces and low temperature radiant heating boilers, replacement of higher temperature furnaces and boilers has been problematic. Research and development of new technologies at the DOE National Laboratories and in industry are creating a new generation of high temperature and wide temperature range heat pumps capable of replacing larger gas driven furnaces and boilers. This presentation will review the current state of the art in heat pumps and give a sneak peek at what is in the research labs and will be coming to market soon. BIO Dr. Ralph T. Muehleisen is the Chief Building Scientist and Buildings and Industrial Technologies Group Leader in the Energy Systems and Infrastructure Analysis Division at Argonne National Lab. At Argonne, Dr. Muehleisen leads research to increase the energy efficiency, sustainability, and resiliency of the built environment while improving the quality of life and return on investment for citizens. His current project portfolio includes R&D related to building energy modeling, future weather data, tools and technologies for decarbonizing the built environment, and decarbonization strategy development and analysis for cities, countries, and continents. |
Stan Nabozny | Unlocking Flexible Demand: Harnessing 68GW of DERs in the US with Thermal Energy Storage
Discover how Thermal Energy Storage can significantly reduce Grid-Scale load and provide a cost-effective alternative to Lithium-ion batteries. Through case studies and examples, the results of TES shifting load and creating efficiency will be shown offering valuable insights for utilities and customers. Refrigerated or air-conditioned spaces can utilize TES as a DER to curtail load during the most expensive periods of the day and shift load to off peak. TES is simple and inexpensive to manufacture and install and lasts twenty years; delivering storage for one-tenth the cost of electric batteries. TES offers a range of benefits over conventional electric batteries, including reduced fire risk, readily available materials for sourcing and manufacturing, and improved efficiency by charging during optimal conditions. Unlike batteries, TES systems do not require heavy parasitic energy consumption to maintain temperature limits and boast a much longer lifespan of up to 20 years. This presentation will describe the tangible benefits and practical implementation strategies of TES. BIO
