CarbonCure and Roberts Oxygen offer CO2 utilisation solution https://t.co/KIR7T4R3Xd
CarbonCure concrete products contribute towards 3 credits under LEED v4 Materials & Resources. The first is Building Product Life Cycle Optimization since CarbonCure’s technology helps to reduce the embodied CO2 emissions of concrete products. Secondly, CarbonCure provides Environmental Product Declarations (EPDs) and Health Product Declarations (HPDs) for concrete products made with CarbonCure’s technology. Projects that include 20 products with EPDs receive a point (2 points if regionally sourced), and projects including 20 products that have HPDs receive a point (2 points if the HPDs meet certain criteria).
CarbonCure products can also contribute towards LEED 2009 credits. Innovation and Design credit, and the credits designed for LEED v4 are eligible as pilot credits under LEED 2009. Details of how CarbonCure’s technology can contribute to LEED points can be found in the LEED package.
An Environmental Product Declaration (EPD) is similar to a nutrition label on a food package, except that it discloses the environmental impacts of building materials. To issue an EPD, a manufacturer conducts a life cycle assessment on its products and measures the environmental impacts in a number of categories, including global warming potential (or the carbon footprint). The EPD is a standardized summary of the findings of the life cycle assessment that is used to compare building materials in the same category.
A Health Product Declaration (HPD) is a standardized document that discloses the health impacts of the ingredients used in a building material. To issue an HPD, a manufacture breaks down the product into its most basic components, and then runs each material through a comprehensive database to reveal any health hazards associated with the component.
