The Department of Defense has an ongoing program to conserve energy at its installations. One method of energy conservation in residential units is the reduction of excessive air leakage by appropriate retrofits. Under the sponsorship of the Office of Navy Family Housing, a demonstration of air leakage reduction was undertaken at the Great Lakes Naval Training Center. Twoprocedural documents were prepared in draft form: a manual for use by supervision and a handbook for the on-base mechanics doingthe air leakage retrofits.
