The document explores the design and functionality of service cores in high-rise buildings, highlighting their role in facilitating essential services like elevators, ventilation, and plumbing. It discusses various elevator types and advancements, such as the 'multi' elevator technology, which allows for vertical and lateral movement, enhancing efficiency. Additionally, it emphasizes the importance of sustainability in structural and service core design to reduce energy consumption and enhance rentable space.

1. CORE DESIGN IN HIGH RISE AND ITS SERVICES
BUILDING MATERIAL AND CONSTRUCTION-IX
WHAT IS CORE ?
An element that gathers the space necessary to provide visual, physical and functional vertical
connections that work effectively to distribute services through the building
servant functions necessary for core :
(1) Services: the main servant facilities of the building , such as elevators, their shafts and corridors,
egress stairs and secure spaces, machine and electrical/communication rooms, toilets and storage
rooms.
(2) Subservices: vertical risers, ducts, pipes and chutes, whose subservant role derives from being
necessary to the operation of the main services. They are generally placed in the residual areas
left free by the design of the main utilities.
(3) Core: the structural shell that often encircles the services.
But how quickly are the elevators actually moving?
The fastest installed elevator reaches speeds of 67 feet per second (20.5 meters per
second), in the Shanghai Tower

But how quickly are the elevators actually moving? The fastest installed elevator reaches
speeds of 67 feet per second (20.5 meters per second), or 46 miles per hour (73.8
kilometers per hour) in the Shanghai Tower.

2. TYPES OF LIFT
 Electric Lift
 Hydraulic Lift(Machine Room At Lower Lvl Only Below 60')
 Paternoster(Continious Lift)
 Double Decker Lift
 Cargo Lift
 Dumb Waiter Lift(Kitchen)
 Capsule Lift(For Exterior)
 Shaft Less Lift Or Pod Lift(Residence Floor To Floor)
 Vacuum Lift(Small Circular For Residence)
ENERGY-EFFICIENT DESIGN OF SERVICE CORES (Relationship Between Service Cores And The
Embodied/Running Energy Of Tall Buildings)
The most important aspects to consider in the design of the service core, so as to enhance its
sustainability, are:
(1) Structural schemes: they influence the amount of materials used for load-bearing purposes.
Structural cores use a lot of material
exterior structures should be preferred—they have more structural significance since ‘it is quite
desirable to concentrate as much lateral load-resisting system components
External structures free the service core from load-bearing functions: the core could, therefore, be
omitted, and greater design variance is possible.
(2) Structural materials: the choice of structural materials has an important role too, since a great
share of the embodied energy of the building depend on them. Despite economic factors, steel should
be preferred for the sustainable design of a tall building; in fact, its embodied energy can be recovered
by recycling the material at the end of the life cycle of the structure, while concrete requires
Demolition
(3) Services: two major services under the control of the design team are responsible for a great share
of floor-space consumption: vertical transportation and mechanical ventilation, since the size and
the number of other services (egress stairs, number of toilets, etc.) are generally imposed by
building codes.
(4) Lift scheme and technology: The aim of the lift engineer (to provide the best transport
service) conflicts with the objectives of developers (to maximize the NRA/GFA ratio). Direct lifts
provide the best comfort level (no changes are required to reach the destination fl oor); however,
buildings higher than 70 fl oors suffer great space inefficiencies from this, and a sky lobby confi
guration is required. Double-decker lifts further improve the space-use effi ciency
(5) Service core design: as shown, the drawbacks arising from an unconventional design and
placement of the service core require careful evaluation, since their negative impact can reverse the
benefi ts generated. Furthermore, aside from Yeang (Yeang, 1991), no author thinks ‘out of the
box’, demonstrating that an external core can easily dissipate its internal gains (elevator machinery,

3. lighting, moisture from toilets, etc.), thus reducing the energy requirements for cooling.
Moreover, since the service core is a transitional space between the inside and the outside of the
building, it can mediate the differential temperature; if one adopts this conceptual idea the thermal
control of the service core, it can produce important savings, thus requiring less energy for cooling
in summer and heating in winter or can even not require HVAC at all.
FUTURE OF CORE
The effective area of the building is what a tenant is willing to rent and to pay for, and therefore can be
called the Net Rentable Area (NRA). Services occupy an area that is equal to SC = GFA − NRA, where
`GFA is the total gross floor area of the building and SC is the area of the service core. Most usable
area we give to core
Loop system
Most of the skyscaper have the core which is centralised .
This is like a person standing with his legs closed.
Also it increases number of elevators in a high rise like 96 may be more

Stacking elevator
 CUT DOWN ELEVATOR WAIT TIME TO ZERO
 INCREASE USABLE FLOOR AREA
 CREATE MORE STABLE STRUCTURE
 TAKE WIND AND OTHER FORCES MORE STABLE
Elevator That Travels Up, Down, And Sideways - All Without Cables
 The elevator is called a "Multi" elevator and the company is using lightweight materials
that will make an elevator cabin 50 per cent lighter than conventional elevator cabins to
be first one in a German office tower
 "Guarantees" a cabin will be available within 30 seconds and handle 50 per cent more
passengers than conventional elevators.
 Elevator that uses magnets instead of cables

4.  Magnets drive the elevator, it can go up, down, sideways or diagonally
 Otis - smart digital connectivity,can call from call and also from where to take lift from
 Solar powed,producing net zero energy use
SERVIES IN CORE
These cores can be interchangable in a buiding
 fire and life safety
 Ventilation

 Hvac
 Stairs
 Lift
 Pluming
 Garbage chutes
 Toilets
 Electrical room
