Green building in facades
Green building Green building focuses to build from a sustainable point of view. The raw materials energy and materials are used as efficiently as possible, while at the same time the negative impact on people and the environment is reduced. The production of the building is considered, as well as the period of use and the environmentally friendly disposal of the materials after use. In order to make all this measurable and comparable, institutions have been established in many countries that carry out the assessment according to various evaluation standards. In Germany, assessment according to DGNB predominates, while in North and South America, as well as India and the UAE, assessment according to LEED is used. In Great Britain by BREEAM and in France by HQE. The DGNB considers the following assessment criteria: ecological quality, economic quality, sociocultural and functional quality, technical quality, process quality and site quality. In the individual criteria, evaluation points are awarded for the achievement of targets. For each of these criteria, points are awarded and weighted to reach a designated level of certification: bronze, silver, gold or platinum. As a member of the DGNB, we are pleased to be able to make our contribution to a more environmentally friendly future. Under the LEED protocols, the classification are certified, silver, gold or platinum. Eight characteristics are scored and weighted to achieve the certification level. A life cycle assessment of the individual product, the socalled environmental product declaration (EPD), is used as the basis for the certifications.
Environmental product declarations in accordance with DIN EN ISO 14025 Type III and EN 15804 are available for the Metawall® facade products.
In order to make sustainable construction practically applicable, measurable and comparable DGNB has developed a certification system based on:
- Life cycle assessment
- Holistic approach
- Performance orientation
With a share of over 80% in new construction and over 60% in the overall commercial real estate market, the DGNB is the market leader among certification system provider in Germany (as of December 31, 2021).
Metawall® products make a notable contribution in archieving the svore required for certification because they stand for sustainability as a fully recyclable product. We can support our customers in the DGNB certification process with our current EPDs of Metawall® A2 and Metawall® B1. These can be found on the IBU-website (Institut Bauen und Umwelt e.V.). In order to be able to certify the building according to LEED, our EPDs at IBU can be used in the European area. For LEED certification in the USA, we have an EPD for the Metawall® A2 according to the standards applicable there.
