Qualitative and quantitative analysis of ultra-efficiency projects: Commonalities, differences, and lessons learned
Year: 2025
Type: article
Abstract: Industrial companies must become more sustainable and environmentally friendly to cope with rising energy and resource costs and regulatory requirements. One approach achieving these goals is the concept of ultra-efficiency, which has been developed and promoted by Fraunhofer in recent years. In many cases, measures to increase sustainability are more effective when neighboring companies work together than when they act individually. This is why the concept of ultra-efficiency has been extended from a single factory to multiple factories in industrial zones and, more recently, to agriculture in mixed-use urban districts. Understanding the benefits and identifying barriers and best practices for fostering such collaboration is important for translating scientific concepts into practice. Therefore, three completed projects are selected and qualitatively and quantitatively analyzed in terms of their similarities and differences. Based on the analyses, a list of eight lessons is highlighted to assist in its quest for greater sustainability: Project complexity increases with diverse stakeholders. Public engagement and demonstrators are key to communication. A strong lead entity is essential early on. Decision maker engagement, clear benefits, data sharing, and independent operator models are key to achieving viable synergies. Long-term planning and infrastructure investment are essential to achieving sustainability goals.
