Geothermal Heat Pumps in K-12 Schools -- A Case Study of the Lincoln, Nebraska, Schools

Geothermal(Ground-Source)Heat Pumps: Market Status, Barriers to Adoption, and Actions to Overcome Barriers

“…TIAX estimated that GHPs would save 30 percent relative to "typical new" equipment, which is reasonably consistent with internal ORNL analysis based on data from a recent ASHRAE research project 61 and a detailed case study. 62 The residential methodology assumes that the reasonable applications for GHPs were heating, cooling, and water heating in homes that were heated and cooled with either combinations of furnace and central AC, or ASHPs. These applications consume about 3.7 quads annually, and the study estimated 45 percent savings relative to typical new equipment.…”

Modelling ground source heat pump system by an integrated simulation programme

“…Most integrated models reported in the past use a simplified ground exchanger model implemented in a building physics model such as TRNSYS (Magnier and Haghighat, 2000) or EnergyPlus (Sankaranarayanan, 2005). For example, Shonder and Hughes (1998) and Shonder et al (2000) developed a model that considers the interactions between buildings, HPs and GHEs.…”

Energy Performance Evaluation of an Educational Facility: The Adam Joseph Lewis Center for Environmental Studies, Oberlin College, Oberlin, Ohio

“…Many of the individual high-performance components have been studied in the past. For example , Shonder, et al (2000) showed that ground source heat pumps systems in educational buildings in a heating dominated climate are among the lowest energy consuming educational buildings. The evaluation presented in this report focuses on the whole-building performance, with additional analysis of innovative systems, such as the photovoltaic, daylighting, and wastewater systems.…”
