Material selection should balance technical performance, environmental impact, supply stability and future maintenance.

Industry developments
Green construction extends from individual energy measures to lifecycle management of materials, construction, operation and refurbishment. Assessment requires clear project boundaries and data.
Engineering practice
Supply, cost, performance and material availability influence low-carbon solutions. Project teams must balance safety, quality, programme and environmental requirements.
New materials and technologies require stated application conditions, testing evidence and site controls rather than conceptual labels alone.
