The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: final report.

Author(s) : ORNL, HUGHES P. J., SHONDER J. A.

Type of monograph: Report

Summary

This report documents an ORNL (Oak Ridge National Laboratory) evaluation of an energy retrofit of 4003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract. Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 2.5 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community gas previously used for space conditioning and water heating in a typical meteorological year. Extract from the table of contents: methodology and calculation of energy savings; maintenance savings; using calibrated engineering models to predict energy savings; geothermal heat pump system models, calibrated to data; comparison of practical BHEx design methods to a Fort Polk data/model benchmark; measurement and verification of energy savings.
