Green building principles in construction
Green building
The concept of green building emerged during the energy crisis of the 1970s and 1980s and emphasises energy efficiency, conservation and appropriate use of natural resources. Today's sustainable construction techniques benefit both owners and builders through time and cost savings.
Design
Simple building shapes are optimal for sustainability. Complex structures lose more energy through their exterior surface area relative to volume, whereas streamlined designs minimise heat transmission.
Durability
A truly sustainable building avoids premature demolition and prevents resource waste. Longevity depends on moisture control, as water damage manifests through paint peeling, rot and mould growth. Climate considerations and proper vapour barriers, especially in cold regions, help extend building lifespan.
Energy efficiency
Quality insulation and airtight construction are essential. Contractors must address air leaks at both small openings, such as wires and pipes, and larger gaps, such as behind fixtures, soffits and bathtubs.
Waste minimisation
Coordination between trades reduces material waste. Recycling cardboard and metal scraps further supports sustainability goals.
Indoor air quality
Proper ventilation and natural lighting prevent volatile organic compounds from paints, formaldehyde from carpets and excessive moisture build-up.
Green materials
Alternatives like bamboo flooring and fly ash concrete offer reduced environmental impact compared to conventional materials such as Portland cement.
Water conservation
Proper groundwater management and innovative water systems protect environmental resources and site viability.
