Over the past few years , there has b een an increasing emphasis on designing low-energy-use buildings. Rising energy prices and clim atic impacts of energy generation are among the important reasons. Super-tall buildings can be sustainable vertical cities of tom orrow, because of their high aspect ratios, efficien cy with res pect to lan d use, and reduced transportation and inf rastructure se...

In cities with tall buildings, emergency responders need an accurate floor level location to find 911 callers quickly. We introduce a system to estimate a victim’s floor level via their mobile device’s sensor data in a two-step process. First, we train a neural network to determine when a smartphone enters or exits a building via GPS signal changes. Second, we use a barometer equipped smartphon...

Efficient vertical mobility is a critical component of tall building development and construction. This paper investigates recent advances in elevator technology and examines their impact on tall building development. It maps out, organizes, and collates complex and scattered information on multiple aspects of elevator design, and presents them in an accessible and non-technical discourse. Impo...

Of the many horrors of September 11, 2001, the sight of people falling and jumping to their deaths from the Towers of the World Trade Center will not be soon forgotten by anyone watching. The sight brutally expressed the desperation of those trapped above the raging fires, unable or unwilling to descend through the wounded structures. Even in light of the eventual collapse of the structures, th...

Recycling steel building components is key to the sustainability of a structure’s end-of-life, as it is the most economical solution. In this paper the effects of usage of recycled steel material in tall buildings aspects are investigated. Keywords—Building, recycled material, steel, structure.
