E3D Energy-Efficient Building Facades with 3D-Printed Concrete

The E³D project is dedicated to enhancing energy efficiency of building facades through the innovative use of 3D-printed concrete elements. By incorporating 3D printing technology with sustainable construction practices, E³D aims to address the limitations of traditional facades and contribute to a more resource-efficient and environmentally friendly building industry.

The E³D project aligns with key strategic goals of sustainable construction by focusing on several critical areas: firstly, it applies 3D printing techniques to create passive façade elements that optimize resource and energy consumption, addressing the challenges posed by climate variations and moisture-related damages. The project's emphasis on 3D-printed concrete allows for greater design flexibility and customization, significantly reducing material use and labor costs compared to conventional methods. Secondly, E³D aims to change the building envelope's role in energy efficiency by incorporating active façade solutions together with the use of a novel insulating material made of cellular lightweight concrete (CLC) for superior durability (active façade solutions) and insulation (CLC). Thirdly, the project prioritizes a user-centric approach, ensuring that the developed solutions are practical and tailored to the needs of stakeholders. By conducting user interviews and life cycle assessments, E³D aligns its goals with real-world requirements, enhancing market readiness and usability.

Collaboration drives E³D, uniting research institutions, academia, and industry experts like RISE and KTH with industry partners including ABB, Adaxis, Heidelberg Materials, FOJAB, and SIKA. Their combined expertise in robotics, materials, architecture, and concrete technology ensures a comprehensive approach to developing, testing, and implementing 3D-printed façade elements.

The E³D project advances 3D printing technology and promotes sustainable, energy-efficient construction, reducing environmental impact and encouraging innovative building solutions in Sweden through collaboration among industry, academia, and RISE's multidisciplinary expertise.
