Report on a formation thermal conductivity test that was performed on the geothermal test bore at Ulbrich Heights at 38 Louis Circle Lane in Wallingford, Connecticut. Data are applicable only within the Wallingford region and should not be extrapolated for other climatic and geographic regions. The analysis assumes no systemic defects in the borehole prior to and during installing and testing. A graphite and Bentonite grouting mixture was assumed to be consistent throughout borehole length. These data were collected as part of the Community Geothermal Heating and Cooling Design and Deployment Grant Program. This associated project's goal is to design and develop a district geothermal heating and cooling system that will serve at least 50% of the heating and cooling load of a 132-unit, affordable housing complex in Wallingford, CT. The project is led by Connecticut Department of Energy and Environmental Protection (DEEP). Borehole drilling and thermal conductivity testing were conducted by Connecticut Wells Inc. and data were analyzed by Geothermal Resource Technologies Inc. (GRTI).

Provided here are a final thermal conductivity test report, a drilling log, and a heat rejection log from Carbondale, CO. Also attached is a report made before drilling, which contains predictions on the hydrogeologic conditions of the drill site. The forty-eight (48.9) hour in-situ thermal conductivity test was performed on the 28th through the 30th, of November 2023. The test was performed at the borehole drilled on November 16th through the 20th, at the 3rd Street Center at 520 S. 3rd, Street in Carbondale, Colorado. Testing was done with a certified Ewbank portable test unit.

This dataset encompasses the development of a geothermal energy system for the West Woodlawn neighborhood in Chicago, Illinois. This project is part of a broader initiative to design and deploy geothermal heating and cooling systems at a community scale. The dataset includes thermal conductivity test results, calculations for borehole sizing based on the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) method, as well as simulated thermal loads based on actual energy usage from individual buildings. Also provided here are files used for numerical modeling via COMSOL Multiphysics to simulate borefield design and subsurface thermal behavior. Two manuscripts are attached, which outline the broad objectives of the project and a description of the numerical modeling methodology and results.

This dataset provides an overview of the design, development, and technical specifications of for a community-scale geothermal heating and cooling system in Carbondale, Colorado. This thermal energy network (TEN) within the town's Three-Two Zero Energy District (32ZED) is part of the town's efforts to achieve carbon neutrality by 2050. Provided here is a case study report detailing project objectives, technical and environmental assessments, building energy modeling, retrofit designs, and community engagement efforts. The dataset also contains design drawings for TEN components, including an Ambient Temperature Loop, Geo-Borefield, High Temperature Loop, and Mechanical and Electrical Designs for retrofitting the Third Street Center in Carbondale. These drawings cover infrastructure like ATL pumps, heat exchangers, boilers, and HTL heat pumps, offering technical blueprints that complement the report?s findings.

This dataset contains materials from the Coalition for Community-Supported Affordable Geothermal Energy Systems (C2SAGES) project, which evaluated the techno-economic feasibility of a community geothermal system for a residential development in Hinesburg, VT. The dataset includes detailed soil conductivity test reports, energy models, borehole design reports, hourly energy loads for heating, cooling, and hot water, and design layouts. EnergyPlus was used to model building energy loads, and Modelica software was applied for geothermal loop sizing based on these loads and soil conductivity results. Python scripts for network design further refined the models. Key files include PDF reports on borehole design (with projections for 1-year, 15-year, and 30-year systems), soil conductivity test results, EnergyPlus modeling outputs, and 2D/3D design drawings in PDF, DWG, and DXF formats. Python notebooks for network design and OnePipe model files are also provided, with Modelica required for viewing certain files. Outputs and modeling data are in various formats including CSV, JPG, HTML, and IDF, with units and data clearly labeled to support understanding of system design and performance for the proposed geothermal solution.

Included here are the mechanical, electrical, and plumbing design report and drawings for the proposed community geothermal system at an affordable housing complex in Wallingford, Connecticut. The report and drawings were developed by LN Consulting, in partnership with the University of Connecticut, which completed the energy modeling that formed the basis of the design work. The drawings can be used as a basis for a Request for Proposals to procure entities to complete construction-ready design documents.

These reports, plans, and drawings review the achievements of Home Energy Efficiency Team (HEET) and its partners to plan and design a network of interconnected ground-source heat pump systems, or geothermal network, in an area encompassing multiple environmental justice (EJ) neighborhoods in the City of Framingham, MA. The materials provided in this dataset include, a) stakeholder and design best practices, b) study on optimal method to interconnect geothermal loops, c) guidelines for monitoring and metering, d) operations and maintenance plans, e) permitting guidelines and f) 10-day driller tutorial curriculum. These materials can guide the efficient and ethical design of future geothermal networks nationwide. The capacity of the system is estimated at 217 tons and is designed to provide 100% of heating and cooling needs for the buildings connected to the loop. In this project, 80 boreholes are used as the main thermal resources, the distribution system (or loop) consists of 0.61 miles of an 8-inch single-pipe at ambient temperature, with the capacity to connect 44 buildings, including 13 apartment buildings from the Framingham Housing Authority, one transitional home, one school building and 29 single family homes. While Framingham already has a geothermal network loop that is currently in the commissioning stage, our proposed project is unique because it is the first utility-led expansion loop (2nd loop) project that will connect to an adjacent existing geothermal loop (1st loop) in a pre-existing neighborhood. Both the 1st and 2nd loops are being installed, owned and operated by Eversource Energy, the utility Deployment Partner.

Included here is a geothermal industry workforce needs assessment report for Connecticut. As part of the DOE-funded Community Geothermal Heating and Cooling Design and Deployment grant, Northeast Energy Efficiency Partnership (NEEP) conducted several online surveys to gain a better understanding of the current geothermal workforce in Connecticut as well as gaps and needs that can be addressed to better support the geothermal workforce. The surveys also looked into training opportunities for geothermal in Connecticut. Attached here is the needs assessment report that was produced from the surveys. The report's appendix includes all survey results from facility managers, training centers, as well as drillers, installers, manufacturers, and engineers. The names of respondents have been redacted.
