SOLUTIONS FOR SUSTAINABLE BUILDINGS THE GUIDE TO LEED Architect: Arata Isozaki/RHWL architects The LEED (Leadership in Energy and Environmental Design) Green Building Rating System is a voluntary, 2 3 Reynaers Aluminium evolving, consensus-based international standard for developing high-performance, sustainable buildings, develops innovative using a comprehensive, point-based system. The LEED certification programme is initiated by USGBC (US Green and sustainable Building Council) and is internationally recognized. The certification confirms that a building is designed aluminium solutions and built to achieve a performance that surpasses national standards for energy savings, water efficiency, CO2 emissions reduction, indoor environmental quality, stewardship of resources and environmental impacts. We develop aluminium solutions for windows, doors, These topics are specified in nine categories, with curtain walls and sun screening, which increase multiple credits, on which the building is evaluated. LEED points are awarded per credit on a 110-point scale, the architectural value of buildings and enhance resulting in four levels of performance - Certified, Silver, people’s living and working environment. Integration Gold and Platinum. of Reynaers Aluminium products in buildings can contribute to the overall sustainability level of the building, thus achieving points for building certificates such as LEED. 40-49 50-59 60-79 80+ points Architect: Arata Isozaki/RHWL architects Using Reynaers Aluminium’s solutions in combination with other building components, up to 24 LEED points can be gained on the following credits (according to LEED v4 for New Construction and Major Renovations): 33 Max.
