The Digital Construction Material Passport (DCMP) is a groundbreaking tool designed to enhance transparency and sustainability in the construction industry. Much like food products require detailed ingredient information, construction materials also deserve comprehensive data to support informed decision-making.
A material passport serves as a declaration of a construction product's essential information, such as its composition, production chemistry, and potential for sustainable construction. This passport is supplied by the manufacturer and accompanies the product through the supply chain. Material passports contain data on chemical content, resource potential, and the product's operational and environmental impact. While some environmental indicators are found in Environmental Product Declarations (EPDs), material passports cover other vital information for construction processes.
Material passports and building passports are related but distinct concepts. Material passports provide product-specific data, while building passports include project-specific information like renovations. Material passports are a prerequisite for building passports.
The DCMP is an open-source free communication format for safely communicating detailed information about construction products, i.e. an electronic material passport specifically for construction products. It can contain information about ingredients, chemistry used in production and the products ability to be part of circular/sustainable construction as well as future resource flows. The data format is based on XML and is free to implement by anyone. To encourage its usage there is also a free editor available to create, read, and update files in this format.
