 5.19.10 Lateral Forces: Describe the structural system to be employed to
resist lateral forces for the structure and associated equipment including
mechanical, electrical and architectural. List Seismic Zone and wind
velocity and what parts of the design are controlled by each.
5.19.11 Special Considerations: Include a statement of any special
considerations that would affect the design, including slanting and fallout
shelter requirements.
5.19.12 Calculations: Provide sufficient structural calculations to
verify the framing system, and major structural elements for loads
including wind and seismic.
5.20
MECHANICAL:
5.20.1 Heating, Ventilating and Air Conditioning (HVAC): Design the HVAC
systems in strict accordance with MIL-HDBK-1190 and MIL-HDBK-1003/3,
"Heating, Ventilating, Air Conditioning and Dehumidifying Systems" unless
specified otherwise by the "SCOPE" or by written waiver from the Officer in
Charge. In the design as well as selection of the appropriate HVAC
systems, consider economic and energy conservation aspects in arriving at
the optimum design solution. Consider such design factors as siting,
orientation, insulation alternatives, reflective surfaces, solar shading,
fenestration, glazing types and natural ventilation. Also consider and
compare alternate solutions based on initial installation, operation and
maintenance costs.
5.20.1.1 Solar Energy: State that solar energy applications for domestic
hot water and space heating were considered.
5.20.2 Heating: State the indoor and outdoor design temperatures and "U"
factors for walls, ceilings, floor, etc., to be used in the design.
Include a general statement regarding the ability of an existing mechanical
system to carry the load when the existing system is expanded or modified.
Describe the heating medium, such as steam, hot water, gas or electric, and
the type of heating system such as convector, baseboard, forced warm air or
unit heater. Describe the type of temperature control, such as electric,
electronic or pneumatic, and indicate energy conservation control systems
to be incorporated. Describe the equipment to be used such as boilers,
convectors, registers, type of pipe, etc.
Indicate the location of the heating plant. Include a brief explanation of
the basis for the selection of the type of fuel, including an economic
comparison with other fuels. Address solar energy feasibility and
applications. Consider energy storage as a means for handling peak loads
without creating corresponding peak demands on utility, also as a help in
down-sizing HVAC equipment.
5.20.2.1 Electrical Resistance Heating: Ensure electrical resistance
heating is limited to applications indicated in NAVFACINST 4l00.4B,
Electric Resistance Space and Domestic Water Heating.
5.20.3 Air Conditioning and Ventilation: Follow applicable design
policies and criteria described in the MIL-HDBK-1190 and DM-3.01 "Plumbing
Systems." Also, consider recommendations in "Air Conditioned Buildings in
Humid Climates, Guidelines for Design, Operation, and Maintenance." In
many instances an economic analysis is required before certain selections
can be made. Provide these analyses, taking into consideration the
equipment, first costs, operating costs and maintenance costs over the
