Interior Signage
Interior signage is important to support the functionality of the facility and for wayfinding.
Use colors, textures, and finish materials on the walls and floors to help define
circulation patterns. Use signs with words and graphic symbols, where appropriate.
Interior signage should be horizontal only and in upper and lower case text, except
where specifically required to be in all capital letters according to Americans with
comply with all other ADAAG requirements for the visually impaired. An interior signage
system should be developed in accordance with UFC 3-120-01, Design: Air Force Sign
Standard.

FACILITY SYSTEMS
Facility systems include specific guidelines for core building systems, such as structural,
mechanical, electrical, plumbing, lighting, fire protection, life safety, and acoustics.
Expeditionary libraries located in austere camp sites present unique system
requirements and compliance is locally driven.
3-5.1
Structural
Select an economical structural system based on facility size, projected load
requirements, local availability of materials and labor, and wind, snow, seismic,
geologic, and permafrost conditions. Select and design the structural system based on
analysis of projected future needs to accommodate future expansion requirements
easily and economically. However, do not over-design the initial construction.
Structural bay sizes should reflect space requirements, economy, and subsystem
dimensions, such as masonry units and ceiling grids. Structural bay sizes should be
compatible with standard shelving unit sizes and standard row-to-row dimensions.
Keep the floors to under two stories in height, where possible, or the costs associated
with designing in progressive collapse criteria will need to be incorporated.

Heating, Ventilation, and Air Conditioning (HVAC)
Provide heating, ventilating, and air conditioning (HVAC) systems in compliance with
comply with the recommendations of the American Society of Heating, Refrigeration
HVAC control and design are also found in AFH 32-1084, Facility Requirements.
Perform a life cycle cost analysis of available energy sources. Inside design
temperatures and relative humidity levels shall conform to criteria in AFH 32-1084.
Provide a night setback for the HVAC system. Provide zone control for maintaining
different environmental conditions in each functional area. HVAC systems for activity
areas, like conference and meeting rooms, should be designed to allow night-time
operation while the rest of the facility is closed. Ductwork serving the children's areas
and the activity areas shall be designed to help acoustically separate those areas from
the rest of the facility. Provide tamper proof thermostats that may be internally
controlled by the facility manager. Provide controls that are programmable and utilize
security features so they are only accessible to authorized personnel. Provide
mechanical exhausts for restroom spaces. Design of new facilities shall ensure that
