GREEN COMPLEX

Eco-friendly Green Complex

Using the eco-friendly system turning the natural resources such as rainwater,
Han-river water source, solar energy, and geothermal energy,
LOTTE WORLD TOWER received the LEED Gold Rating by U.S. Green Building Council.

Utilizing 14.5% of total energy use as renewable energy
Internal production of 51,168Mwh of electric power annually
Reduction of 23,113t CO2 which is equivalent to planting
8.5 million 20-year-old pine trees annually

Electric vehicle infrastructure

Strong Mat Foundation

Compact Filling of Mat Foundation of
72m(W) X 72m(L) X 6.5m(H)

As the supertall skyscrapers on the side of Lake Michigan in Chicago U.S.,
the safety of skyscrapers near a lake has been verified
by the cutting-edge geodynamics and civil engineering technology.

Foundation(MAT) construction

The weight of the completed Lotte World Tower is 750,000 tons,
and it is equivalent to a total weight of around 10 million
Seoul residents assuming an adult weighs 75kg.

To support the LOTTE WORLD TOWER, the MAT foundation sized
72m (W) x 72m (L) x 6.5m (H) was constructed by digging the ground to 38m in depth.
108 steel columns of 1m in diameter and 30m in length were driven through
the firm bedrock layer to reinforce the bedrock, and then placing reinforcing bars and then
placing reinforcing bars of 4,200 ton and pouring high strength concrete of 60,000 ton.

This is much thicker than the world’s tallest building
Burj Khalifa and firmer using 2.5 times more concrete.

Wind and Earthquake Resistance Design

009

Earthquake resistance design
to withstand Richkter-9 or higher magnitude earthquakes

Core wall and 8 Mega Column
The core wall and eight mega columns which are
the center frame of the tower supports the vertical gravity.
Outrigger and Belt Truss
The outriggers and belt trusses that function like joints
of bamboo are installed in every 40 floors in LOTTE WORLD TOWER
to withstand the traversal pressure of wind and earthquake.
Diagrid Method of Construction
The diagrid structure at the top connects
the steel frames like a mesh to withstand
the traversal pressure of typhoon and
earthquake without additional column or support.

Structural Safety Management Technology

Structural Health Monitoring System

“Structural Health Monitoring System” to manage the structural safety of Lotte World Tower.

The Structural Health Monitoring System monitors the structural safety and risk from typhoon, earthquake and terror. More than 600 sensors and the cutting-edge measuring system installed in the building checks the health of building in real time using the integrated monitoring system.

Disaster Prevention System

Disaster Prevention System of IBC (International Building Code) and NFPA (National Fire Protection Association) Standard

In case of fire, the fireproof concrete can withstand for at least 3 hours, and 19 high-speed elevators are immediately converted into the evacuation elevator to evacuate people from each floor to five safety zones within 15 minutes. 15,000 residents can all be evacuated within 63 minutes. It is the better plan than Burj Khalifa which requires 89 minutes to evacuate people to four safety zones.

More than 160,000 spring coolers and 30,000 fire sensors are installed in LOTTE WORLD TOWER. Five fire fighting water sources can supply the water for up to 300 minutes, and the emergency power generator operates the spring coolers to delay proliferation of fire in case of blackouts.

The safety system exceeds the international standard, and the disaster prevention system operated for 24 hours a day can immediately mobilize the internal fire engines and fire fighters (including professional fire fighters) to extinguish a fire quickly. Moreover, the joint anti-terror training in the realistic simulated situation against the international terror ensures prevention of risks and protection of citizens.
