This paper is a review of the development of a software application that analyzes energy consumption and conservation options for existing Navy Family Housing neighborhoods.This software was developed in response to Executive Order 12902, which requires energy audits of federally owned facilities, identification of energy conservation measures with a payback of ten years or less, and implementation of those conservation measures by the year 2005. This Windows 95 compatible application performs these audits by calculating energy loads and associated utility costs for entire homogeneous housing neighborhoods. An extensive facility database, containing building characteristics and weather and utility rate information, provides the basis for these calculations. This database is updated annually, incorporating changes in energy costs, additions and deletions to inventory, and revitalization of existing neighborhoods. Energy conservation measures are calculated on an interactive basis. Both simple payback and savings-to- investment ratios are used to evaluate potential savings. Saving calculations incorporate both utility savings and maintenance avoidance and/or cost. The application includes a Revitalization Wizard to adjust conservation measure costs when similar work is being performed for nonenergy reasons. For example, if windows are being replaced for nonenergy reasons, energy savings are automatically calculated for a vinyl, dual-pane low-E window at no cost. The rationale being that you only pay for the replacement window once, but you receive multiple benefits (i.e., energy, maintenance, lead-based paint removal, etc.). Similarly, savings on upgraded windows are calculated on the delta between their cost and the “base” window’s cost. Summary reports compare existing units’ energy performances against a revitalized neighborhood with composite conservation measures and against new construction standards.
