- Tinted, energy-efficient, low-e, double-pane glazing is encouraged; provide triple-pane glazing in extreme environments.
- Glazing color shall follow Installation Facilities Standards (IFS).
- Translucent wall panels may be integrated into wall systems.
- Do not use mirrored glazing.
- Fully integrate applicable shading designs for overhangs, louvers, light shelves and grilles.
- Where appropriate, install window screens to take advantage of natural ventilation.
Connect interiors and exteriors with doors and windows to provide daylighting, passive thermal comfort methods, and to lower life cycle costs. Provide an efficient thermal envelope and cost-effectively integrate passive heating and cooling systems. Design the building envelope to control the transfer of these elements: heat, air, moisture, light/radiation, and noise. Design each control strategy holistically and use an integrated design approach to optimize building performance while promoting occupant comfort, health, safety, security and productivity.
Select doors and windows for a long life span with the possibility of one or more uses during that time. Provide durable long-lasting windows and doors in all high-use areas and in all exposures subject to weathering and UV light. Lower life cycle costs by selecting low-maintenance materials. Hardware types and finishes shall be long-lasting, showing minimal effects of use over their lifespan.
Windows may be of different sizes and proportions based on the direction a wall is facing, but a facility’s overall design shall be cohesive and of consistent quality. Use an organized placement and pattern of windows that coordinates with the overall facility design.
Ensure the type and level of quality of doors and windows is appropriate for the Facility Group designation.
Following the directives of UFC 1-200-02, determine whether passive design strategies are cost-effectively incorporated before the active and mechanical systems are designed. Integrate windows to support passive systems. Concentrating windows on south-facing walls is encouraged when climate appropriate.
Evaluate life-cycle cost effectiveness of passive (non-mechanical) ventilation and cooling systems such as shading integrated with window systems. Passive thermal comfort methods are allowed and encouraged. Operable windows, when permitted, must be coordinated to ensure interiors are secure and protected from rain, snow and inclement weather.
Window and door systems should enhance indoor environmental quality and must promote thermal comfort, moisture control and daylighting. Material specifications should include consideration of environmentally preferable products, products with recycled content, as well as low-emitting and biologically-based products.
