period specified by the latest criteria.  Furnish a report, complete with
necessary back-up data and calculations, at the 60% submittal.  Furnish
computer floppy disk (3 1/2 inch) on input made for Carrier and Trane Ultra
programs.  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.  Consider the use of natural ventilation in
lieu of air conditioning for space cooling.
5.20.3.1  Air Conditioning:  Provide a brief description of the air
conditioning system proposed, such as the type of air system or type of
terminal unit, type of refrigeration systems, size, factory or built-up
systems, any redundancies and facility for expansion, etc.  Specify areas
to be air conditioned and whether air conditioning is authorized in
accordance with MIL-HDBK-1190.  The values for the U-factors and R-factors
noted in Table 8.4 of MIL-HDBK-1190 are to be considered mandatory unless
specified otherwise by the "SCOPE" or by written waiver from the Officer in
Charge.
5.20.3.2  Ventilation:  Discuss ventilation required by criteria and the
means to be used to accomplish dilution ventilation, exhaust ventilation,
make-up air, etc.
5.20.3.3  Design Temperatures:  State the required inside temperatures and
relative humidities and outside wet and dry bulb design temperatures.
Outside design temperature should correspond with NAVFAC P-89, "Engineering
Weather Data."  Include "U" factors for the type of construction proposed
and a statement of the economics of applying insulation and/or sun shades.
5.20.3.4  Equipment:  Describe equipment to be used, such as reciprocating
or centrifugal compressor, condensers, air handling equipment, duct system,
piping, etc., and type of building temperature control system such as
electric, electronic or pneumatic and sequence of operation.  To preclude
problems with proprietary equipment and for large equipment requiring
clearances for installation and maintenance, ensure that several
manufacturers products can satisfy the contract requirements and is
suitable for the space allocated.  List the manufacturers and model numbers
and include catalog cuts for all major equipment in the Basis of Design.
5.20.3.5  Design Analysis:  The final design analysis shall have complete
cooling load calculations, a psychrometric chart with conditions shown and
manufacturers' equipment listed that would satisfy the design.  Provide
explicit balancing and testing procedures for extensive systems.
5.20.3.6  Controls:  Design Air Force projects in accordance with Air Force
Engineering Technical letter ETL 83-1 and Change 1 Design of Control
Systems for Heating, Ventilation, and Air Conditioning Systems.  This
requires the designer to use design instructions, control drawings and
technical specifications attached to Change 1 to ETL 83-1 for all Air Force
(except SAC) HVAC design and construction.  For SAC HVAC designs, use SAC
standard HVAC control drawings.  Design Navy projects in accordance with
NFGS-15901 and NFGS-15910.  The intent is to provide a control system which
is simple to trouble shoot and maintain and to provide complete detailed
maintenance documentation.
5.20.4  Plumbing:  Base plumbing fixture quantities on occupancy allowances
for naval shore facilities, except that plumbing fixtures for the
physically handicapped shall be provided in accordance with Federal
Standard 795, "Uniform Accessibility Standards" (April 1, 1988).  Indicate
the type of materials proposed for water pipe, soil pipe, stacks, etc.  Use
5-20
