This file contains a zipped file that contains many files required to run GEO2D. GEO2D is a computer code for simulating ground source heat pump (GSHP) systems in two-dimensions. GEO2D performs a detailed finite difference simulation of the heat transfer occurring within the worki...

The goal of this project was to develop a detailed computer simulation tool for GSHP (ground source heat pump) heating and cooling systems. Two such tools were developed as part of this DOE (Department of Energy) grant; the first is a two-dimensional computer program called GEO2D ...

Feasibility study completed to identify the economic and operations benefits of using a geothermal based heat pump to supplement domestic hot water production for a large county detention facility.

This PowerPoint presentation describes the ground source heat pump system installed at the District Energy Corporation's thermal plant at the Lancaster County Adult Detention Facility in Lincoln, NE. The detention facility is a 270,000 sq. ft., 750 bed, secured facility.

Drawing showing the configuration of 667 bore holes drilled to depth of 300 ft. for the Lancaster County Adult Detention Facility geothermal heat pump system.

Ideal Homes built a Zero Energy Home (ZEH) in Edmond, OK, (a suburb of Oklahoma City) using an extensive package of energy efficient technologies and a photovoltaic array for site electricity generation. The ZEH is part of a demonstration project to exhibit high efficiency techno...

This Dataset contains field research raw data, analysis spreadsheet, photos, and final report from the Hathaway Solar Patriot House Building America Case Study project.

The Hathaway Solar Patriot House was a Building America field research case study from 2001 to 2004. A report on this project is available in this record or from the National Renewable Energy Laboratory. http://www.nrel.gov/docs/fy05osti/37731.pdf

This library contains g-functions (thermal response functions) for standard, regularly spaced vertical borehole ground heat exchangers. In total, it contains 34, 321 configurations. To permit interpolation, each configuration has g-functions for heights of 24, 48, 96, 192, and 384...
