Business Context
Increasing building height can improve land utilization and increase development capacity, particularly on valuable urban sites. However, taller buildings experience greater wind and lateral-load effects, increased vertical transportation requirements, more demanding foundations, and greater structural complexity, causing structural cost to increase.
Real Estate & Construction TRIZ Resolution
Structural efficiency at height should be improved through system configuration rather than proportional increases in material. Optimized cores, perimeter systems, outriggers, appropriate geometry, distributed stiffness, lightweight construction, and integration between architectural and structural functions can improve performance while controlling additional structural demand.
Applicable TRIZ Principles
Principle 17 – Another Dimension uses vertical development to increase land productivity.
Principle 5 – Merging integrates architectural and structural components so common elements perform multiple functions.
Principle 3 – Local Quality concentrates stiffness and strength where structural demand is greatest.
Expected Outcome
Increased development capacity
Controlled structural cost
Improved structural efficiency
Better utilization of valuable land
Decision Indicators
Early indicators include:
Structural cost rises disproportionately with additional floors.
Building height is limited primarily by structural inefficiency.
Lateral-load systems consume increasing usable space.
Structural solutions rely mainly on additional material.
Height increases create disproportionate foundation requirements.
