high rise vertical circulation and service

Study onVertical Circulation & Service……………..

Vertical circulation:Vertical circulation, as usually applied in architecture, is the movement of people and goods between interior spaces in buildings and to entrances and exits. Safe, convenient, rapid circulation is essential for all buildings under both normal and emergency conditions.

Element of Vertical circulation:1. RAMP.2. STAIR.3. ESCALATOR.4. ELEVATOR.

Service:Simply state that service is defined as those part of a building that consists of the service lift, fire stair,Toilet, M&E service riser duct .

Core:

The core of a multistory building that integrates functions and service needs for established occupants. Such areas are normally composed of toilet facilities, elevator banks, janitors’ closet, utilities, mechanical facilities, smoke shafts and stair. Core also known as facade envelope is a spatial element for load-bearing high-rise building system

Types of core:

1. central core

2. Split core

3. End core

4. Atrium core

Structure of Core:

a. If the building structure been R.C.C,the core structure should be shear wall. In this case core structure may not be steel structure.

b. If the building structure been steel , the core structure should be steel structure. In this case core structure may be R.C.C structure.

c. If the building structure been Composite ,the core structure should be shear wall. In this case core structure may not be steel structure.

Arrangement pattern & spatial effect of Vertical circulation:(ELEVATOR)

ARRANGEMENT TWO-CAR GROUPING

•Side-by-side arrangement is best•Passenger face both cars& can react immediately•AVOID separation of elevators•EXCESSIVE separation destroy advantages of group operation

THREE-CAR GROUPING

•3 cars in a row is PREFERRABLE•2 cars opposite 1 is acceptable •PROBLEM: location of elevator call button


ARRANGEMENT FOUR-CAR GROUPING

•commonly in large, busier buildings•2-opposite-2 arrangement is the most efficient

SIX-CAR GROUPING

•found in large office buildings, public buildings & hospitals•provide quantity & quality•3-opposite-3 position is PREFERRED •dimension of the LOBBY must not be less than 3m or 3.6m if function as a passageway

ARRANGEMENT EIGHT-CAR GROUPING

•the largest PRACTICAL group•4-opposite-4 arrangement


EXPRESS ELEVATOR :• fastest elevator• interval stoppage: specific floor• interval time: 33 ft/s(World Trade Centre) 54 ft/s (Taipei 101)

LOCAL ELEVATOR :• normal speedy elevator• interval stoppage: each floor• interval time: up to 10 ft/s

ELEVATOR

1.Central Core


Elevator position preferable in centre &Horizontal circulation is easier

ELEVATOR

2.Split Core


Individual elevator layout position according to using purpose &

Horizontal circulation is noteasier

ELEVATOR

3.End Core


Horizontal circulation is noteasier

4.Atrium Core


Horizontal circulationis easier

STAIR & FIRE EXIT

1.Central Core

Arrangement pattern & spatial effect of Service:(STAIR & FIRE EXIT)

Easily escape for central position & mechanical lighting

2.Split Core

STAIR & FIRE EXIT


More easily escape for split position

3.End Core

• Toilet layout should be in service core• Toilet block should be near of riser duct• Block position is located in a place so that

people can use it without access in lift lobby

Ventilating is the process of replacing air in any space to provide high indoor air quality ( to control temperature, replenish oxygen, or remove moisture, odors, smoke, heat, dust, airborne bacteria and carbon dioxide). Ventilation is used to remove unpleasant smells and excessive moisture, introduce outside air, to keep interior building air circulating, and to prevent stagnation of the interior air.

Types of ventilation:1. Natural ventilation: occurs when the air in a space is

changed with outdoor air without the use of mechanical systems, such as a fan. Most often natural ventilation is assured through operable windows. Open windows or vents are not a good choice for ventilating a basement or other below ground structure. Allowing outside air into a cooler below ground space will cause problems with humidity and condensation.

2. Mechanical ventilation: an air handling unit or direct injection to a space by a fan. A local exhaust fan can enhance infiltration or natural ventilation, thus increasing the ventilation air flow rate.

3. Mixed Mode Ventilation: both mechanical and natural ventilation processes.
