Building Orientation

  1. Ensure the site will accommodate optimum requirements for building orientation, which is with the long axis parallel to the east/west direction for rectilinear CONUS buildings.
  2. Meet Installation Facilities Standards (IFS) requirements for the locations of the building’s passive and renewable-energy systems—including geothermal and solar systems—and exterior shading systems.
  3. Locate the building(s) and permitted ancillary structures to promote solar gain, solar shading, natural ventilation, rainwater harvesting, wind buffering and other beneficial passive systems. Consider natural ventilation during the design of HVAC systems.
  4. Consider relationships to adjacent sites and their facilities and infrastructure, and cost effectively integrate building systems to harvest heat, grey water or other beneficial byproducts.
  5. Consider the “public side” of the building, its views and the location of the main entrance.

Confirm the NEPA process is successfully complete prior to beginning the site design.

Utilize an integrated design approach to align on-site engineered systems with the natural environment. During design, conduct a site analysis of the associated climate including local and regional context and ensure the site accommodates a building’s optimum orientation, configuration and massing. When possible, preserve previously undisturbed/undeveloped areas of the site.

Conduct a life cycle cost analysis and diligently evaluate feasibility of Enhanced Use Leases, Energy Savings Performance Contracts and Public-Private Partnerships in developing sites to provide the greatest long-term benefit to the Air Force.


Work with the base community planner to select a site and gain appropriate approvals. Incorporate cost effective passive climate responsive design solutions to minimize life cycle costs. Assure Installation Facilities Standards (IFS) requirements for site features and systems and federal guidelines for water resources can be attained. Address climate resilience in site design and minimize ongoing maintenance requirements. Support alternative transportation and promote walkability and cycling.


Follow DoD and AF criteria and define site related climate risk mitigation strategies in the IFS. Prioritize the use of passive systems in site solutions. In areas at high risk to tornadoes coordinate the location of engineered storm shelters for occupants with direct egress path from facilities.
