Every high-rise carries a hidden number few developers ever ask about: how much of its floor area actually does anything - and what the rest is quietly costing in energy, every single year, for the life of the building.

Backed by a dataset of 34 buildings, 20 expert interviews, and eight projects tracked across five design stages, this book proves what practitioners have long suspected but never measured: spatial efficiency isn't a leasing metric with a side effect on sustainability - it's one of the most powerful, controllable levers on a building's lifetime energy performance. In hot arid, high-density markets specifically, each percentage point of Net-to-Gross ratio lost is associated with a 10.43 kWh/m /year increase in energy intensity - 46% steeper than the equivalent effect in temperate-climate buildings (R = 0.887).
