Leadership In Energy And Environmental Design
Already widespread and active in more than 40 countries, the LEED (Leadership in Energy and Environmental Design) certification system assesses and attests to the environmental, social and economic sustainability of buildings considered as a whole. According to the LEED classification criteria, highly environmentally sustainable construction materials contribute to achieving credits and increasing the points for the building. All the slabs presented in this instrument are certified to contain percentage of recycled material higher than 40% in accordance with the ISO 14021 standard, thus guaranteeing the highest points according to the LEED system.

it is the most widespread standard in the world and it is designed to measure the environmental impact of buil¬dings by applying specific criteria for assessing the sustainability of the construction. The rating system requires types of certification deter¬mined by strict technical parameters and quality control which in turn are based on the most recent technology and knowledge available.
