16. STRUCTURAL SYSTEM:
TRUSS WITH SHEAR WALL TYPE
 The mixed-use structure features
 The structure is pretty straightforward
featuring regular steel frame and concrete
shear wall.
 The hard part would be analyzing the
vierendeel truss which is structurally
indeterminate.
 A concrete central stepping core
 The central column is articulated at the top
of the building with illuminated glass beams,
which extend 38 meters above the tower,
adding a dramatic presence to the skyline
Central
STEPPING
CORE

17. • The members are not triangulated but form
rectangular openings, and is a frame with
fixed joints that are capable of transferring
and resisting bending moments
• The diagonal members are omitted in these
structures, their function must be taken over
by the remaining members which are thereby
subjected to flexural and shearing stresses
Virendeel Truss :

18. STRUCTURAL SYSTEM:
FOUNDATION
•The foundation system consists of
caissons, central mat slab & perimeter cast-
in-place foundation walls
•The load on foundations was 11,401.5 lb/SF
which is normal for a very tall skyscraper.
•The foundations would be deep bored piles or
caissons so that all this load is transferred to
deeper soil levels that are more stable
•Transfer loads to solid rocks of bearing capacity
20 tons per square foot.

19. STRUCTURAL SYSTEM:
ELEMENTS & CORE
 The main structural part is Core Shear
Wall.
 The structure consists of a concrete
core containing cast-in-place slabs
within the core.
 The building envelope is a unitized
curtain wall system.
Core Shear Wall

20. HVAC SYSTEM
•Featuring two prominent cooling
towers in the front of the building, it
uses well insulated glass and sunlight
infiltration to ensure efficient
cooling/heating system. It is
assumed that the HVAC system is a
mixture between Radiant
Heating/Cooling.
•"Chilled Structural Beams", which
house pipes of running water that
cool the columns, that in turn cools
the surrounding air.

21. CHILLED STRUCTURAL BEAMS:

22. HVAC SYSTEM:
Each home and hotel room is provided with a
low-e double glazed curtain facade. It helps to
 maximize views while minimizing heat
transfer inside the tower.
 Displacement ventilation at the occupant
zone
 The base building construction materials
have been selection for low volatile organic
compound (VOC) emitting finishes and
furnishings, protecting human health and
improving indoor air quality.
Double-glazed
curtain facade

23. CURTAIN WALL
SYSTEM:
• Heating, lighting, and
total energy
consumption, which is
about 34-38%, 28%,
and 17-20%,
respectively.
• For the cooling energy
consumption, the
dispersion is about 55%
for the east and west
façade 65% or the
south facade, and 42%
for the north facade

24. FIRE FIGHTING SYSTEM:
 Fire Escape Stairways are built in
Comcast Technology Centerin each
floor.
 Fire Resisting Concrete are used.

26. ELECTROMECHANICAL SYSTEM:
 The coordination of high
performance mechanical
systems captures plant and
distribution side efficiencies
resulting in reduced
conditioning loads.
 These systems include active
chilled beams, displacement
ventilations
 Dual flush toilets reduce
potable water consumption

27. ELECTROMECHANICAL SYSTEM:
• The electrical power
distribution system is
fed by a dual utility
service and
incorporates double
ended switchgear.
• Taps require zero
energy as they are solar
powered.

28. LIGHT OPERATING SYSTEM:

29. SERVICE CORE:
 No. of Elevators : 40
 Top Elevator Speed : 8 m/s
 separate banks elevators serving
both entrances.
 one of which is an all-glass elevator
located along the tower's exterior on
the 19th street

31. SERVICE CORE : HOTEL LEVEL

32. SUSTAINABILITY :
• The green design strategies employed by
the property developer reduces water
usage by 40%,
• cuts back on heat-island effect by 70%
• Uses a glass curtain to block 60% of heat
while allowing 70% of the sun’s visible
light
• Reducing energy used for air conditioning
while utilizing natural light to its fullest.
• The developer also diverted 77% of
construction waste to salvaging and
recycling.
• Introduce Leed Platinum Design Theory

33. SUSTAINABILITY : CON….
