The Skyscrapercity forum has pictures from the China Broad Group 202 story building site. Site preparation has started and the actual assembly of the world’s tallest building will take 7 months.
(H/T to readers Anthony Scalzi and phamnuwen for the additional information)
Chinese urban per capita area of about 500 square meters
Sky City Urban per capita area of only 4 square meters (including buildings surrounding land)
• construction area of 1.05 million square meters
The base is 9,000 square meters, floor Covering rate of 1%, significantly reducing construction
In the past, high-rise building energy consumption was much higher than conventional buildings but the Sky City will be the opposite. It will use a lot less energy
• 20 cm wall insulation (walls 70% decrease heat loss)
• quadruple glazing (windows 60% decrease heat loss)
• window shade (located at the outer glass inside, isolated heat)
• New air heat recovery (reducing ventilation heat loss 80%)
• CCHP (equal to the cooling and heating without energy)
• HVAC annual energy 90kWh/m2 (9 liters of oil equivalent)
More than 30 buildings have been built using the factory mass production (can be built) Broad Group method.
