Tri-Service Energy Tool, Worldwide

To simplify development of A-E solicitations, NAVFAC Southeast turned to RS&H to develop a one-of-a-kind custom energy modeling spreadsheet tool for U.S. Army, Air Force, and Navy facilities. The tool estimates the baseline facility energy consumption and costs for 14 typical DoD building types, following the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) 90.1 (2007), Appendix G (Performance Rating Method).

Facility types include:

  • Airfield Fire & Rescue
  • Air Control Tower
  • Instructional (Classroom) Training
  • Operational (Simulator) Training
  • Reserve Training
  • Indoor Firing Range
  • Aircraft Maintenance Hangar
  • Vehicle Maintenance
  • Armory
  • Multipurpose Administrative
  • Housing
  • Dining
  • Nursery and Child Care
  • Indoor Physical Fitness

To accomplish this task, RS&H used the Carrier Hourly Analysis Program (HAP) to develop over 440 building energy models. The data from the energy models was compiled and used to create an energy usage algorithm for the various building energy end-use components.

To use the tool, the user selects the building type and city and inputs the building size in square feet. The spreadsheet tool then produces an ASHRAE 90.1 – 2007 baseline energy consumption and cost estimate. The results also include a breakdown of the annual energy use and annual energy cost for each end-use category required for LEED energy models.
