Construction waste: The Latest Architecture and News

Two primary building approaches are commonly identified in architecture and design: solid versus hollow construction. These methods vary significantly across different cultures and regions, specifically for interior partitioning systems, when they appear interchangeable. Each has its own established practices influenced by local materials, labor preferences, climatic conditions, and cultural traditions. When architects and designers focus on their local context, it is easy to overlook the broader construction assumptions, limiting design flexibility and methodology. This raises an important question: How do these two building approaches differ?

Focusing mainly on interior systems, the distinctions between solid and hollow construction largely stem from the availability of materials and workforce preferences. For example, in the United States and Japan, stud walls, both wood and metal, are frequently used for partitioning. Conversely, brick remains the predominant material for partition walls in regions such as Hong Kong and southern China. Why do we build differently, and what are the benefits and challenges of each building methodology?

The construction industry is one of the largest in the world, and cement and concrete are literally the building blocks of its success. Evolving from prehistoric caves to today’s towering skyscrapers, concrete structures have and will continue to be vital components of modern civilization, providing long-lasting, reliable support for buildings, roads, bridges, tunnels and dams. So much so that concrete is the most consumed material on Earth, second only to water, while the steel used to reinforce it is by far the most commonly used metal. But this doesn’t come without high environmental costs: concrete accounts for 8% of global CO2 emissions, much of which come from the extraction and transportation of aggregate materials such as sand, gravel and crushed stone.
