6.5.1 Observations on Suspended Ceiling System
Interface Design
The suspended ceiling system interface DSM includes 6 iteration cycles
(Figure 6.14). These comprise two groups with overlapping cycles in
each. HVAC distribution system, structural frame system, and lighting
system play a major role in these iterations. The floor structure system
does not cause any iteration.
The main critical elements (the elements which cause large cycles) in
the first iteration group are beam depth, HVAC distribution layout, air
diffuser quantity, required depth for lighting equipment, structural
element connection details, HVAC equipment and superstructure
integration scheme, plenum depth, floor to ceiling height, lighting fixture
width and length, and air diffuser layout. The main critical elements in
the second iteration group are weights and maximum weights of lighting
fixtures and air diffusers, and hanger spacings.
Beam depth is a critical parameter since it is sensitive to two
downstream parameter decisions: HVAC distribution layout and HVAC
and superstructure integration scheme. In the actual design process,
the largest beams had been used at the periphery of the building to
save space in the plenum where HVAC ducts would pass. However, the
beams also had been needed to be slightly oversized in order to allow
some of ducts pass through them.
