Materials: Moving Beyond Glass and Steel
1. Mass Timber (CLT and Glulam)
Cross-Laminated Timber (CLT) and Glulam are becoming increasingly popular. These materials are strong enough for mid- to high-rise buildings, lighter than concrete, and they store carbon instead of emitting it.
When using timber, engineers must rethink load paths, fire protection, and lateral stability. This involves encapsulation layers and careful design considerations.
Example: The C6 Tower in Perth, Australia.) aims to be the world’s tallest timber building.
2. High-Performance Façades
Move over single-skin glass walls. Today's focus is on triple glazing, low-e coatings, and thermal breaks to minimize heat loss.
Dynamic glazing (like electrochromic glass) automatically adjusts tint levels. This reduces the need for cooling inside the building.
3. Photovoltaic Facades
Solar panels are no longer limited to roofs. Facades featuring BIPV (Building Integrated Photovoltaics) now generate power directly from walls.
