One building has been constructed using imported components, while the other, has been constructed using locally manufactured materials and components. Local content, or the use of local materials and products and materials, can make a big difference in sustainability performance.
Less transportation means less pollution and environmental damage. Locally available skills and materials support effective maintenance and repairs, increasing service life and reducing waste. Procurement of local materials and components create a diversified local economy that is more resilient to global economic shocks and exchange rate changes.
Local content, or localisation, in built environments, can be supported through the use of the Sustainable Building Assessment Tool (SBAT) 'Local Economy' criteria. The Sustainable Building Materials Index (SBMI) can be used to support more sustainable and efficient local building material and component manufacturing processes.
