Open Innovation at Xella

Open Innovation means that a company’s traditionally closed innovation process is extended outwards beyond its boundaries. With Open Innovation, internal and external ideas flow together to develop new products, services and business models.

For Xella this means entering into partnerships with universities and research institutes as well as other companies – where worthwhile and beneficial. Participation in third party funded joint research projects is also part of our innovation strategy. The path we choose in each case depends entirely on the requirements and the opportunities. One thing is certain though; it will become increasingly important for us to benefit in an appropriate way from external networks and cooperative ventures and to make an active contribution to them.

Xella is a member of several networks and joint research projects:



Future_bizz is a Germany-wide Open Innovation network for companies in all sectors of industry. Its aim is to monitor trends and share new business ideas about life and work.

Verbundprojekt Napos

Napos Joint Research Project

(Nanostructured, highly insulating autoclaved aerated concrete masonry“)

Project content: Development of an homogenous, recyclable and resource-efficient solid unit consisting mainly of lime, sand and water which has excellent inherently insulating properties even without an exterior insulation and finishing system.
Project sponsor: German Federal Ministry of Education and Research (BMBF)
Project partners: Celitement GmbH, Karlsruhe Institute of Science (KIT), XTF
Project duration: 2014-2017


EU-Project [H]house

“Healthier Life with Eco-innovative Components for Housing Constructions”

Project content: Development of innovative, sustainable facade materials and internal wall systems designed to create a healthy indoor climate and increase user comfort. The aim of the concept is to develop building components for both existing residential buildings as well as new buildings with a focus on resource efficiency and reduced energy use.
Project sponsor: EU, 7th Framework Programme
Project partners: International consortium comprising 3 research institutes (including BAM, the Federal Institute for Materials Research and Testing), 5 SMEs and 4 industry partners.
Project duration: 2013-2017

Realdania, Danmarks Tekniske Universitet

Internal insulation of historic buildings

Project content: Application test of mineral insulation systems for the internal insulation of historic buildings.
Project sponsor: Realdania
Project partners: Technical University of Denmark (DTU), XDK, XTF
Project duration: 2014-2016

Karlsruher Institut für Technolgie / Hochschule für angewandte Wissenschaften München

Implementation of a pilot phase for the assessment method “Kleinwohnhausbauten (Ein- und Zweifamilienhäuser)” (Small-scale housing construction (single-family and two-family homes))

Project content: The aim of the project was to test the evaluation method developed in 2013 for ‘single-family and two-family homes’ using real construction projects and to design a practical certification system. The aim is to launch the certification system on the market following a pilot phase.
Project sponsor: Stiftung für Forschungen im Wohnungs- und Siedlungswesen (Foundation for housing and settlement research), Berlin
Project partners: University of Applied Sciences Munich, Ingenieurbüro Prof. Hauser GmbH, Karlsruhe Institute of Science (KIT), XTF
Project duration: 2014-2015

Technische Universität Dresden, Institut Bauklimatik

Energy-efficient refurbishment of buildings of historic importance using capillary-active, mineral-based internal insulation 

Project content: Monitoring the functional performance and safety of use of a mineral-based, vapour-permeable internal insulation used in the energy-efficient refurbishment of Güterfelde Castle.
Project coordinators: Institute of Building Climatology, Dresden, XTF
Project duration: 2012-2017

Innovationsnetztwerk Morgenstadt

Innovation network “Morgenstadt: City Insights”

Project content: Strategic system partnership and cooperative venture based on the research field ‘City of the Future’.The initiative has a broad research remit which goes way beyond buildings in the City of the Future to include energy, urban processes, production & logistics and mobility & transport.
Project coordinator: Fraunhofer Gesellschaft
Project partners: 21 industry partners, 11 German cities and 10 Fraunhofer Institutes
Project duration: 2012-2017
