Image & Character
Building Types Group 3

Hangars are designed for industrial uses, heavy wear, and ease of maintenance. Where appropriate, hangars are the centerpiece of mission facilities and are designed with a similar level of design (if not similar finishes or materials) as a Group 1 facility. They are designed to create optimal conditions for mission support. Design features that emphasize mission functions without compromising security are encouraged. Pedestrian movement among buildings is facilitated through the design of the built environment and its relationship to the site and other exterior features.


1. Massing & Articulation

The massing is articulated in response to the building program and be able to accommodate generous daylighting of the interior where appropriate. Because of its overall building size, attention is given to balancing simplicity of form, structure, and envelope with architectural impact. A strong, easily identified entrance is appropriate. Overall articulation is modest, appropriate to Group 3 Buildings, allowing form and color to create the overall character.

Roof Style

2. Roof Style

Sloped standing-seam metal roofing is preferred for most of the roof area. Due to large spans, low-slope roofing is acceptable. Use overhangs to protect window openings as much as practical. Create covered gathering areas at the main entrance. Use simple roof forms, but they may be responsive to programmatic function. Curved roofs may be used for the main form or to highlight architectural features, such as the entrance.


3. Primary Entrances

Provide a covered entrance to accommodate groups of 20 to 30 people. Open-sided (versus recessed) covered entrances are preferred. Provide large glazed areas to designate the entrance and a modest level of finishes on the exterior.


4. Shading Devices

Use aluminum louver and/or shading devices at windows. Shading devices integral with the building façade also is encouraged. Provide shading devices and canopies at covered entrances for strong architectural presence.


5. Secondary Entrances

Provide a covered entrance to accommodate groups of three to four people, using glazing to identify the entrance. Provide coverage to protect openings for utility entrances.


6. Fenestration

Use vertically proportioned punched window openings with aluminum windows in limited appropriate areas. Larger expanses of curtain walls or storefronts are appropriate for this large facility type. Storefronts and/or curtain walls may be used to designate entrances, gathering areas, or vertical circulation. Use of linear or other shapes as design elements is permissible in moderation. Translucent wall panels are appropriate to assist daylighting spaces.
